What is Logynon?
Logynon is taken by mouth with the objective of preventing pregnancy.
Each pack of Logynon contains three strips of 21 tablets.
Logynon tablets contain ethinylestradiol and
levonorgestrel. They are synthetic versions of the naturally occurring female
sex hormones,
oestrogen and
progesterone. Ethinylestradiol (spelt ethinyloestradiol in the UK) is a
synthetic version of oestrogen and levonorgestrel is a synthetic form of
progesterone.
Combined oral contraceptives like Logynon work by over-riding the normal
menstrual cycle.
Logynon
Each Logynon contains the active
ingredients levonorgestrel and ethinylestradiol. This is a phasic pill with
variable dose of oestrogen - 30, 40 , 30 micrograms and levonorgestrel 0.05,
0.75 and 0.125 microgram levonorgestrel.
In 1921 it was suggested that extracts from ovaries could be used as birth
controls. Diosgenin was first extracted from the Mexican yam in 1941 and this
continues to provide a source for the production of sex steroids including
norethisterone (norethindrone in the USA) and progesterone (Progest
progesterone and progestogen in PMS;
progesterone replacement therapy) and Crinone (progesterone
and progestogen in PMS).
How popular are birth control pills?
A birth control was first used in a clinical trial in 1956. The pill became
available in the USA in 1960 and in the UK in 1961. By 1986, 95% of sexually
active women in the UK under the age of 30 had used the combined birth control
pill at some time and by 1991 almost half the women aged 20 years in the UK were
taking it.
A survey in 1995 found that 25% of the 13 million women in the UK aged 16-49
were currently using the combined birth control pill. The peak age group was
20-24 with 48% of all women and 70% of contraceptive users choosing this method.
The use of the various methods of contraception varies from country to country.
In Japan less than 2% of women use the combined birth control pill whereas in
Holland 40% of sexually active women do so.

What are the benefits of Logynon?
Logynon suppresses the natural hormone cycle providing:
The additional benefits include:
- improvement of acne (Q5.10).
- oestrogen for those with amenorrhoea (absent periods) and low oestrogen
levels (Q6.21).
- reduction of excess body hair (hirsutism -
hirsutism treatment).
- reduced incidence of functional ovarian cysts (3).
- improvement in endometriosis (Q15.19
and Q15.20).
The four-weekly bleeds that occur whilst taking the combined birth control
pill are not periods (menstruation) but withdrawal bleeds. Menstruation is a
bleed that occurs each month spontaneously and not in women who are taking
hormonal treatment such as the combined birth control pill.
Will Logynon improve my periods?
The majority of patients report reduced flow and less period pain. There are
occasional exceptions so that a few ladies with light periods find their
menstrual flow increased by the combined birth control pill. During early pill
cycles in particular there may be some breakthrough bleeding. Some women do not
have a withdrawal bleed during pill-free
interval. If this happens for two consecutive cycles a pregnancy test should be
considered. Absence of the withdrawal bleed is not detrimental to health. When
Logynon is discontinued, the periods may take a few
months to return to normal. Premenstrual syndrome is less common whilst taking
Logynon although there may still be some symptoms
for the last few days of the cycle.

Could Logynon alter my libido?
Relieved of the stress of possible unwanted pregnancy, some women report
increased initiation of sexual activity. Others find their libido reduced,
perhaps as there is some sub-conscious wish to have a child. If libido is
reduced, vaginal discomfort due to infection should be excluded. Otherwise a
change to a less progestogenic pill may help.

What are the risks of taking Logynon?
Thromboembolism (blood clots): The early combined oral contraceptive
pills contained 150 mg of the oestrogen mestranol together with norethynodrel
which is a progestogen. The first report of thromboembolism (a blood clot
forming in a vein within the leg or pelvis and then travelling to the lungs) in
association with Logynon came soon after the
combined oral contraceptive pills were introduced. The pharmaceutical industry
has made enormous efforts to reduce the risks associated with the oral
contraceptive pills whilst maintaining their contraceptive effectiveness.
Essentially there have been two avenues that have been explored. Firstly, the
amount of oestrogen in Logynon has been reduced and
secondly newer progestogens have been developed.
The oestrogen in Logynon reduces LH and FSH
production and therefore suppresses follicular development and ovulation (Q
2.3). There has been concern that reducing the amount of oestrogen in the
combined oral contraceptive pills could lead to contraceptive failure. Over the
years it has been found that the lowest dose of oestrogen that remains effective
is much lower than originally contemplated. The original 150 mg was reduced to
100mg then 50mg. The majority of pills prescribed today have less than 50mg of
ethinyl oestradiol and two have just 20mg (Logynon 20 – Parke Davis; Mercilon –
Organon). At this level, the oestrogen content is only a little more than that
found in hormone replacement therapy (HRT). HRT does not suppress follicular
development or ovulation and it therefore follows that the 20mg oestrogen pills
will be the minimum effective dose.
Mortality risks are negligible.

What side effects could I have whilst taking Logynon?
The vast majority of patients taking Logynon
feel very well but, as with any medicine that has benefits, some minor
side effects are occasionally reported. These include:
- altered body weight (some gain a few pounds and others lose a little).
- nausea (feeling sick) and vomiting.
- mastalgia (breast tenderness).
- headaches (Logynon should be stopped if they
become severe).
- altered libido (sex drive - Q15.5) with many women noticing an increase and
others a reduction.
- depression.
- reduced or absent menstrual flow (Q15.4
;24.17A).
These side effects usually settle within two or three months.
What is the effect of birth pills on body weight?
All of us are intermittently gaining or losing
weight.
Inevitably some patients find that they gain
weight around the time of starting Logynon but
others observe a weight loss.
In a personal computer search of the medical
literature from 1966 to date I found exactly fifty papers (articles in medical
journals) where weight change in relation to Logynon had been studied.
- Thirty-six papers indicated no change, eleven
found an increase varying from 0.3kg to 2.4Kg.
- Three papers found weight loss with the
combined oral contraceptive pill for women who were overweight or who had
polycystic ovaries.

Will Logynon increase my vaginal discharge?
Cervical ectopy (erosion -
cervical erosion)
appears to be more common in women taking the combined oral contraceptive pill
although the newer lower dose pill seem to cause this less frequently. Cervical
ectopy only requires treatment if there are persistent significant symptoms
after excluding other problems such as infection. Contrary to popular belief,
there is no evidence that Logynon increases the
incidence of candida (thrush).
Does Logynon increase my chance of pelvic infections?
There is no increase in the incidence of Candida infection in pill users. The
incidence is the same as in women with intrauterine devices and those using no
contraception. Bacterial infections that gain entry to the pelvis through the
cervix are less common in pill users as the progestogen makes the cervical mucus
thick. However, there is no protection against viruses or chlamydia.

What is the relationship between Logynon and fibroids?
Surprisingly, studies show that the combined oral contraceptive pill reduces
the chance of fibroid development. It is a surprise because both oestrogen and
progesterone are factors in fibroid development so fibroids shrink after the
menopause (HRT-Add-Back).
The current presumption is that the total of these hormones provided by the
combined oral contraceptive pill in a month must be less than the natural
hormone output by the ovaries.

Will Logynon increase my blood pressure?
For the majority of women, the blood pressure increases on the combined oral
contraceptive pill by an average of 1mm Hg (a tiny amount). An increase of
5-10mm Hg may be of clinical importance but 1mm really does not matter. This is
an example of a statistical (mathematical) proven increase that has no
consequence from the medical point of view.
The international recommendation is that the combined oral contraceptive pill
should not be started or continued if your blood pressure is 160/100 or higher.
High blood pressure can be a factor in heart disease and strokes and as a few
women (about 1%) may develop clinically significant raised blood pressure,
checks should be carried out periodically. Your blood pressure should be
measured before you start Logynon and three months
later. If your blood pressure is normal it should be reviewed at six months
intervals and after two years it can be reviewed annually.

Does Logynon have any effect on the blood?
All chemicals in the blood are eventually removed and eliminated from the
body. The liver plays a key role in this process and this is true for oestrogens
and progestogens. The oestrogen and progestogens in the combined oral
contraceptive pill results in a slight alteration in the fat chemistry of the
blood. There is a rise in low-density cholesterol (Q
27.4) and triglycerides and a reduction of high-density cholesterol. These
changes have been reduced by the more modern pills.
When we cut ourselves a blood clot forms to seal the wound and stop the
bleeding.
- This involves a cascade of chemical reactions in the blood that lead to the
clot forming.
- Some people are particularly prone to inappropriate blood clots, which occur
within the veins usually in the legs or pelvis.
- If such a blood clot, which is called a deep venous thrombosis, becomes
dislodged it can travel to the lungs and causes a pulmonary embolism, which is a
serious life threatening condition.
- The combined oral contraceptive pills do have a slight adverse effect on the
clotting mechanism. Again, the new low oestrogen dose preparations are less
likely to lead to problems.
What is the relationship between Logynon and thromboembolism (blood clots)?
Deep venous thrombosis and pulmonary embolism are uncommon if you are young
(Figure 15.1). There is a slight increased risk of these problems if you are
taking a combined oral contraceptive pill and the risk is further increased for
those who are overweight or who smoke. The newer and lower oestrogen dose pills
probably cause fewer problems. To put the risk in context, a woman taking the
combined oral contraceptive pill is more likely to be hospitalised as a result
of an accident than from a complication associated with her pill.
A study by the World Health Organisation (WHO) published in 1995 provided
evidence that the newer pills with their lower oestrogen content are associated
with lower incidence of thromboembolism than the earlier higher oestrogen dose
pills. This study also brought attention to the relationship between the
progestogen in the combined oral contraceptive pill and thromboembolism.
What is the relationship between the combined oral contraceptive pill and heart
attacks?
The combined oral contraceptive pill has slight adverse effects on the lipids
(“fat” chemicals) in the blood and these changes are known risk factors for
heart disease. Heart attacks before the menopause are rare. Studies of patients
on the early high dose preparations of the combined oral contraceptive pill
found a five-fold increase in the incidence of heart attacks. Further studies
demonstrated that there are usually confounding (additional) factors
contributing to the attacks. In particular, smoking increases the risks. With
the more modern low dose pills the risks are probably lower. The latest evidence
suggests that there is no increased risk of heart attacks for oral contraceptive
users.
The current recommended advice is that smokers should discontinue the
combined oral contraceptive pill at the age of 35years. The best advice is that
smokers should stop smoking.

What is the relationship between Logynon and strokes?
Strokes are uncommon in young women but there is a marginal statistical
increase in those who have taken the combined oral contraceptive pill. Strokes
may involve haemorrhage (bleeding) within the brain or reduced blood supply (ischaemia)
to part of the brain. In young women it is the bleed variety of stroke that is
the more common. One study in Europe found no significant increase in the chance
of the bleed variety of stroke in association with the combined oral
contraceptive pill. Smoking and high blood pressure are more important risk
factors and these confuse any analysis of the risks of the combined oral
contraceptive pill.

Does Logynon affect the breasts?
Many women find that their breasts are slightly larger when taking the
combined oral contraceptive pill. Breast discomfort (mastalgia) may respond to
vitamin B 6 (pyridoxine) 50 mg once or twice daily. Otherwise a change of pill
should be considered. Should milk production occur (galactorrhoea) investigation
of the prolactin hormone level is indicated (hyperprolactinaemia).
Benign breast disease (Q
27.16) tends to improve when the combined oral contraceptive pill is taken.
Could I feel depressed as a result of taking Logynon?
A few women describe a little depression when taking the combined oral
contraceptive pill. The pill does not cause severe depression. If a change of
pill does not solve the problem, pyridoxine (Vitamin B6) 50mg daily may be
beneficial but it can take up to two months to be effective.

What is the relationship between Logynon and cancer of the ovary?
Several studies have provided convincing evidence that ovarian cancer is less
likely to occur in women who have taken the combined oral contraceptive pill.
Your risk of ovarian cancer is reduced by about 50% if you have taken the
combined oral contraceptive pill for at least five years. The protection
continues for about 15 to 20 years after you stop taking the combined oral
contraceptive pill. This protection appears to be independent of the brand of
pill used. It is likely that the combined oral contraceptive pill needs to have
been taken for a minimum of two years to achieve this protection. The incidence
of ovarian cancer seems to be falling and this is likely to be related to this
benefit of the combined oral contraceptive pill.

What is the relationship between the combined oral contraceptive pill and cancer
of the uterus?
Progesterone and progestogens protect against endometrial (lining of the
womb) cancer. The combined oral contraceptive pill provides progestogen for 21
days each month. Studies indicate a 40% reduction in the incidence of
endometrial cancer when the combined oral contraceptive pill has been taken for
more than five years. Protection continues for more than fifteen years after the
combined oral contraceptive pill is discontinued.

What is the relationship between the combined oral contraceptive pill and cancer
of the cervix?
Sexual activity and number of partners are the factors that have large
impacts on the incidence of pre-malignant and malignant conditions of the cervix
(neck of the womb -
Q32.16). The sheath (condom) provides mechanical protection not only
against pregnancy but also against sexually transmitted disease. It prevents
transmission of the human papilloma virus believed to be responsible for
cervical cancer. It may be that the early studies suggesting that the combined
oral contraceptive pill increased the risk were only reflecting the prevention
of transmission of the virus with the barrier method.
There has been a suggestion that the combined oral contraceptive pill may
increase the chance of pre-malignant conditions of the cervix developing in
women at risk but this remains an area of debate requiring more data. There is
no reason to stop Logynon if you have been found to
have an abnormal smear test provided appropriate investigations and treatment
are undertaken (Pap Test). Related Medical Abstracts - Click on the paper title:-
What is the relationship between Logynon and cancer of the breast?
This question is discussed in
Q32.43.
Deciding on the best pill oral contraceptive pill.
The objective is to choose an effective pill, with the lowest side effects
and the lowest possible hormone content. A pill with 30 or 35mg ethinyl
oestradiol is now the usual first choice. A 50mg pill may be recommended for
women on some anti-epileptic drugs (Q16.20).
If a friend has recommended her brand of pill to you there is unlikely to be
a reason why you should not try it. Similarly, if you are about to recommence
oral contraception and have been happy with one preparation in the past, it
would seem reasonable for you to try it again.
Whilst I am taking Logynon, what monitoring should
I receive?
Medical opinion varies as to how often patients on the combined oral
contraceptive pill should be checked.
At your first visit the doctor will need to review your medical history and
to undertake a general and pelvic examination.
A further review will be undertaken about three months later to ensure that
the chosen pill is acceptable.
Many family planning clinics have specialist nurses to undertake some of
these routine assessments.
The blood pressure is checked at each subsequent visit to the clinic,
which will probably be at three to six monthly intervals. A persistent blood
pressure of 160/100mm Hg or more would be an indication to stop the combined
oral contraceptive pill and to consider medication to reduce your blood
pressure.
Pelvic examination and cervical smears every three years are probably
ade quate unless you develop symptoms. More frequent monitoring may be indicated
for those with risk factors.
Product information for oral contraceptives currently includes the
recommendation that all women should have breast and pelvic examination before
starting the combined oral contraceptive pill and at regular intervals whilst
taking it.
The Committee on Safety of Medicines and the Faculty of Family Planning and
Reproductive Health Care in the UK now believe that it is unnecessary for all
women taking the combined oral contraceptive pill to have routine breast and
pelvic examinations either before or whilst taking the combined oral
contraceptive pill.
Blood pressure should always be measured but other physical examination
should only be performed if considered appropriate by the clinician.
One of my family has had a blood clot (thromboembolism). Should I have any
special tests?
Thromboembolism may occur during immobilisation particularly after a major
operation. If your relative had a thromboembolism in such circumstances we would
not anticipate that you are at increased risk.
Some families have disorders of the blood clotting mechanism, which
predisposes them to thrombosis (thrombophilia). If several of your relatives
have been affected, particularly when the blood clots have occurred
spontaneously without an obvious cause, we would need to consider thrombophilia.
There are blood tests that may detect these abnormalities but they are extremely
expensive. In these circumstances, it may be appropriate to seek advice from a
haematologist (blood disorder specialist).
Does an aeroplane journey increase the risks of taking Logynon?
Modern commercial aeroplanes are pressurised. The increased risks of
venous and arterial thrombosis associated with high altitude are therefore
eliminated.
There have been reports of circulatory complications after a flight but this
is e qually true for those not taking the combined oral contraceptive pill.
Underlying dehydration, following sunbathing, alcohol or a gastro-intestinal
upset increases the risk.
Many airline stewardesses take the combined oral contraceptive pill. They
know the importance of ensuring ade quate fluid intake and they will take a
little walk every hour or so to keep their circulation going.
It has been suggested that Aspirin 75mg daily should be considered before the
flight and for a few days afterwards.
There is one concern about flights for women taking Logynon particularly if they are travelling West as they may
inadvertently take a pill late. It may be prudent to keep one watch set at the
time of your home and use this to guide you on when you should be taking your
pills.
Are there times when the combined oral contraceptive pill should be prescribed
only with special caution?
Yes, there are times when a patient has medical problems such that the
combined oral contraceptive pill can be prescribed but only with special
caution. More careful monitoring is required. Examples are:
- moderately elevated blood pressure (hypertension) requiring medication
(patients with a history of high blood pressure in pregnancy can be given the
combined oral contraceptive pill but again the blood pressure should be checked
more frequently).
- obesity (greater than 50% above ideal weight for height) is a reason for
caution. Calorie control and exercise should be encouraged with a view to
ensuring weight loss.
- hormones may, on occasion, aggravate depression.
- sickle cell disease (an inherited cause of anaemia found generally in people
of Afro-Caribbean origin); this was regarded as a contraindication for the
combined oral contraceptive pill as there is an increased risk of thrombosis;
some authorities now suggest that the combined oral contraceptive pill can be
given with caution. It may be prudent to discontinue the combined oral
contraceptive pill during any episodes of immobilisation.
- some medical conditions when they are mild but not if they are severe.
Examples are diabetes, systemic lupus (SLE), Crohn's disease and renal disease.
Varicose vein problems are not a contraindication for Logynon. Varicose veins are more frequently found in association with
obesity and this would be a reason for caution. The pill should be stopped if
you need injection treatment.
When a woman has a medical problem that may be affected by Logynon, the doctors involved in her care will usually liaise to
ensure consistency of advice. Ultimately it is for the doctors caring for the
woman to provide her with the information that she requires to make an informed
choice.
The more common contraindications to Logynon
include:-
- pregnancy.
- a history of arterial or venous thrombosis.
- cardiomyopathy (an inflammatory condition of the heart).
- ischaemic heart disease (heart attacks or angina).
- familial conditions associated with thrombosis.
- severe migraine.
- strokes.
- diabetes.
- liver diseases.
- gall stones (the combined oral contraceptive pill can be taken after
surgical removal of the gall bladder).
- porphyria (an inherited condition affecting the break down process of red
blood cells)
- very high blood pressure.
- smoking at age 35 years or more.
- severe systemic lupus (SLE) requiring steroid treatment.
- cancer of the breast or uterus.
As with any medication, your doctor will check to
see if there is any specific medical reason contraindicating the combined oral
contraceptive pill.
On which day of my menstrual cycle should I start my first course of Logynon?
Nowadays, we recommend that it should be started on thefirst day of a
period as this provides immediate contraceptive cover. The next period
will occur after 23 days but subsequent periods will be at 28 day intervals.
Following childbirth, the combined pill can be taken if the baby is
not being breast-fed; breast feeding combined with progestogen-only pills
provides excellent contraception. During pregnancy and for the first two weeks
after childbirth there is an increased risk of thromboembolism (blood clot
problems -
surgery risks)
and this may be further increased by Logynon (Q15.14).
- The pill should be commenced no earlier than 21 days after childbirth.
- If there has been a high blood pressure problem associated with pregnancy or
there is a tendency to obesity, Logynon should be
further delayed.
- If Logynon is commenced more than 21 days after
childbirth, additional contraceptive precautions are required for the first
seven days. The combined oral contraceptive pill can be commenced immediately
after early miscarriage or pregnancy termination.
If periods are absent or infrequent, and this problem has been
appropriately investigated (Q6.6),
a course of progestogen tablets will usually provide a withdrawal bleed and
Logynon can be commenced on the first day of bleeding.
Can I start Logynon whilst I am breast-feeding?
Logynon is likely to reduce the quantity and
quality of your milk which will contain a relatively large amount of
hormones. If oral contraception is required the combination of a progestogen-only
pill with breast-feeding will provide highly effective contraception for
you.
Can I take Logynon if I have had episodes when
I did not see my periods (amenorrhoea)?
- The amenorrhoea should be investigated, before Logynon is prescribed, and treated if a specific cause is found (Q6.21).
- If pregnancy has been excluded there is no reason why Logynon cannot be prescribed.
- When Logynon is subsequently discontinued the
menstrual cycle will return to the pattern that would have occurred if Logynon had not been taken.
This means that the amenorrhoea may recur and fertility medication may be
required if a pregnancy is planned.
Can I start Logynon if I am not currently seeing my
periods?
Absence of periods (amenorrhoea) needs to be investigated (Q6.6).
Provided that both pregnancy and a problem requiring treatment have been
excluded, amenorrhoea is not a contraindication to Logynon.
Does it matter if I do not see a period whilst taking Logynon?
A withdrawal bleed ('period' whilst taking Logynon) does not have to occur with every pill-free interval.
Provided you have taken Logynon correctly, a
pregnancy is very unlikely.
If you do not see a withdrawal bleed it usually means that the lining of your
womb is not building up sufficiently to result in a bleed. This reflects the way
that the womb is responding to the combined oral contraceptive pill and does not
indicate what will happen when Logynon is stopped
if you wish to have a baby.
From the medical point of view there is no reason to change Logynon if the problem continues and there is no need to run any
tests.
If you are unhappy that you do not see a withdrawal bleed, a different pill
may suit you better.
A girl of 13 had extremely heavy and painful periods
which were controlled for two years with a monophasic pill (Microgynon). At the
age of sixteen she returned to my clinic as she kept missing withdrawal bleeds.
She had not started sexual activity but was worried that she would lose her
fertility. We reassured her that medically there was no anxiety. After
discussion she was started on a phasic pill (Trinovum) and withdrawal bleeds
occurred.
Some women find that when they stop the combined oral contraceptive pill they
do not see their periods. Until twenty years ago this was called 'post-pill
amenorrhoea'. Research then showed that, with few exceptions, patients with
amenorrhoea after discontinuing the combined oral contraceptive pill had
infrequent or absent periods before they commenced the combined oral
contraceptive pill. The pill had simply masked an underlying problem and was not
the cause.
What is the advice when my changing combined oral contraceptive pill
preparation?
The simplest guide is that the current combined oral contraceptive pill
should be taken until the course is completed and the new pill should commence
on the first day of the withdrawal bleed; no additional contraception is
required but the first cycle on the new pill will be just 23 days.
What should be done if breakthrough bleeding occurs whilst I am taking Logynon?
The first course of action is to check that there is no cause for the
bleeding other than Logynon preparation. A
missed pill, antibiotics or gastro-intestinal upset may have occurred. There
may be a local cause such as vaginitis (inflammation of the vagina), a
cervical polyp (cervical
polyps) or other cervical disease. These can be assessed by medical
examination. A bleed early in pregnancy can be mistaken for break-through
bleeding.
Light breakthrough bleeding may be acceptable for perhaps three months and is
likely to settle. Otherwise a change of pill preparation is appropriate. If the
oestrogen content is very low increasing this may be the first line of approach.
Increasing the progestogen content (Table
16.1) or changing from a monophasic to a bi-phasic or tri-phasic pill (Table
16. 2) are other possible remedies.
Can my combined oral contraceptive pill withdrawal bleed be planned to avoid
weekends?
If a pill packet is commenced on a Sunday, the withdrawal bleed should occur
on weekdays. When starting Logynon for the first
time, if you delay to the next Sunday rather than commence on the first day of
the period, additional contraception is required for the first seven days. For
those on monophasic pills (Table
16.1) who wish to convert to a Sunday start, it is probably best to take two
packets back-to-back and then finish the second packet on the Saturday. The
third packet is commenced on the following Sunday. The other option would be to
continue taking Logynon from a spare pack until the
next Sunday. This spare packet can be kept in reserve for similar cycle
adjustments when required.
Can I take Logynon without a seven-day pill-free
gap?
From the medical point of view, there is no benefit in having the gap,
and if you are taking a fixed, rather than a phasic pill, you can take it back-to-back without pill free days. This may
avoid a bleed during a social event or a vacation. Logynon is a phasic pill and
so this option is not available
What should be done if a pill is missed?
If a pill is taken more than 12 hours late we regard it as missed. The missed
pill can be taken and the course continued at the appropriate time. Additional
precautions (usually condoms) should be used for the next seven days. If there
are less than seven pills remaining in the course, the next packet should be
commenced without a seven-day gap; if you are on an ED (every day) regimen, the
seven inactive pills should be omitted. The risks of pregnancy are highest when
the missed pill is at the beginning or end of a cycle.
Could I conceive whilst I am taking Logynon?
There are few failures associated with the combined oral contraceptive
pill provided that the combined oral contraceptive pill has been taken
correctly.
Ideally, Logynon should be taken at the same
time each day.
There is a maximum safety limit of 12 hours.
If Logynon is taken more than 12 hours late
additional precautions are essential (Q16.18).
The seven pill-free days allow the natural hormone cycle to begin.
If the gap is inadvertently increased, ovulation (egg release) can occur and
pregnancy may ensue.
During a gastro-intestinal upset (vomiting or severe diarrhoea) Logynon may not be absorbed and additional precautions are
required. The additional precautions should be continued for at least seven days
after the bowel has settled. Similarly, some antibiotics reduce the absorption
of the combined oral contraceptive pill and the same precautions would apply.
Can combined oral contraceptive pills interact with other medication?
Some medications, such as those used in the treatment of epilepsy, increase
the rate that the liver breaks down chemicals including the oestrogen and
progestogen in Logynon.
Rifampicin, used for a short course for those at risk of meningococcal
meningitis, is so powerful at speeding up chemical breakdown pathways that
although given for only 2 days, its effects may last for 4 weeks; additional
contraceptive precautions are advisable to cover this. Rifampicin may also be
prescribed for several months during treatment of tuberculosis. This may make
the lower dose pills in particular less effective and breakthrough bleeding more
likely. Higher dose pills (e.g. 50mg ethinyl oestradiol), in these
circumstances, achieve similar hormone levels to lower dose pills taken by women
not taking the anti-epileptic treatment.
Some broad-spectrum antibiotics (effective against a wide variety of
bacteria) can reduce the absorption of oestrogen. Break-through bleeding may
occur if the hormone levels fall below a threshold. For those on long-term broad
spectrum antibiotics (e.g. for treatment of acne) the bacteria in the intestine
become resistant to the antibiotic and after the first two weeks there is no
need for additional contraception.
The combined oral contraceptive pills may interfere with treatment for
diabetes, depression and high blood pressure; appropriate adjustments may be
required.
Can Logynon affect future fertility?
The short answer is no.
At one time it was thought that the combined oral contraceptive pill could
cause 'post-pill amenorrhoea (absent periods after stopping the combined oral
contraceptive pill -
birth control pill)
and this was associated with anovulatory (failure of egg release) infertility.
Subsequent studies showed that those who developed post-pill amenorrhoea had
similar cycle problems before commencing the combined oral contraceptive pill.
The pill was not the cause but it had been masking the underlying problem.
It seems likely that, if anything, the combined oral contraceptive pill may
conserve fertility by reducing the incidence of pelvic inflammatory disease (Q
20.2) and endometriosis (Q9.11).
Pregnancy termination (abortion), which should be prevented by Logynon, can have complications leading to infertility (Q19.14).
Modern contraceptive methods are extremely effective. There is a danger that
one can assume that when Logynon is discontinued a
pregnancy will occur quickly. With increasing age, fertility decreases if you
want a child, you should not leave it too long (Q9.6).

There is no medical advantage in taking a break from Logynon. All too frequently, an unplanned pregnancy will occur. The
concept that the combined oral contraceptive pill should only be taken for five
or ten years at a time is based in mythology.
Surgery and Logynon.
One of the potential complications following an operation is a blood clot in
one of the veins in the legs or pelvis (surgery
risks) and we surgeons try to reduce the risk as far as possible.
As the combined pill is also associated with a tiny risk of blood clot
problems (Q15.14)
we need to consider whether Logynon should be
stopped before we operate.
Ideally, Logynon should be discontinued four
weeks before major surgery or any operation on the legs.
The pill can be
recommenced on the first day of the next period provided that this occurs at
least 14 days after the operation.
If there is need for a major operation when Logynon has not been discontinued, your surgeon may recommend injections of heparin
for a few days to thin the blood a little.
There is no reason to discontinue Logynon for
minor operations or intermediate operations such aslaparoscopy.
There is no recommendation to stop progestogen-only pills or other
progestogen contraception for surgery.
Until what age can I take Logynon?
The official recommendation for women with no risk factors is that there is
no upper age limit for taking the combined oral contraceptive pill.
Women who smoke should stop Logynon by the age
of 35 years as they are at increased risk of heart disease. The best medical
advice is to stop smoking.
As we get older the risks of heart disease increase and fertility falls. If
you are taking the combined pill and wish to continue with oral contraception,
it is probably advisable to change to a progestogen-only pill at the age of 50.
Logynon and the menopause.
The pill does not change the time of the menopause. Each egg appears to
behave as if it has a timer which determines when it will go into an active
phase (Q
2.3). If the hormone environment is not appropriate, the active phase is cut
short and that egg fails to develop. One of the important ways that Logynon works is that it creates a hormone environment that
prevents further development of the eggs that are going into the active phase.
The pill does not stop eggs from going into the early active phase (otherwise
the menopause would be delayed in pill users).
I am taking Logynon. How will I know if I have
reached my menopause?
As you approach the age of 50 there is an increasing chance that you will be
reaching your menopause but withdrawal bleeds will continue for however long the
combined oral contraceptive pill is taken. There is no test that can absolutely
define when the menopause has occurred even for a woman who is not taking the
combined oral contraceptive pill and seems to have stopped her periods although
a blood test for FSH and oestradiol levels (Q
26.14) can be a useful guide. If you want to know if you are likely to have
reached your menopause, the blood test should be scheduled for the last day of
the combined oral contraceptive pill-free interval.

In what circumstances should Logynon be stopped
immediately?
The pill should be discontinued and urgent medical advice sought if any of
the following occur:-
- Severe headache accompanied by visual disturbance.
- Sudden visual disturbance or difficulty with speech.
- Weakness or numbness in one part of the body.
- Severe pain in a calf.
- Unexplained shortness of breath.
- Severe chest or abdominal pain.
- Jaundice.
What symptoms are commonly associated with taking the oral contraceptive pill?
Many women experience mild symptoms that are a nuisance or inconvenience
although they are not damaging to their general health.
Many of these symptoms occur frequently amongst non-pill takers so the
combined oral contraceptive pill may not be responsible. Anxiety that the
combined oral contraceptive pill may be causing major problems frequently leads
the patient back to her doctor.
The more common symptoms include
- breast discomfort,
- bloating,
- headaches,
- vaginal discharge,
- aches in the legs and
- weight change.
After checking that all is well, your doctor will probably only need to
reassure you. frequent change of pill prescription is rarely indicated.
Should Logynon be discontinued if I develop
headaches?
Migraine involves a headache with visual disturbance. If severe migraine
starts, Logynon should be stopped immediately and
not recommenced. The progestogen-only pill is not contraindicated. If mild
migraine occurs, Logynon should be stopped but it
may be tried again later with careful monitoring and advice from your doctor.
Headaches by themselves are not a contraindication to Logynon. If they occur around the time of the combined oral
contraceptive pill-free interval, the combined oral contraceptive pill may be
taken for nine weeks without a break before a pill-free interval reducing the
symptom from 13 to 5 times each year.
Varicose veins and Logynon.
Varicose veins are not a contraindication against taking Logynon.
Vomiting and diarrhoea. How does this affect my oral contraceptive pill taking?
If you have taken a pill within two hours and you do not think that another
will stay down, you should recommence Logynon as
soon as possible and use additional contraception until seven days after the
vomiting has settled. The pill should be continued rather than omitted for the
seven pill free days if they would occur during this time. Mild to moderate
diarrhoea does not interfere with pill absorption.
Starting a pregnancy - When should I stop taking Logynon?
There is no evidence of any increased risk of abnormality for the baby in
women who conceive soon after stopping the combined oral contraceptive pill. The
underlying risk of congenital abnormality (a structural defect of one or more
parts of the body present at birth) is 2% of all babies. Even when pregnancy
occurs accidentally in women taking the combined oral contraceptive pill, the
risk of congenital abnormality is not increased above this 2% level.
At one time, one of the most common problems facing obstetricians was
determination of the duration of pregnancy.
- Only if the menstrual cycle was normal and the mother was certain about the
date of the first day of the last menstrual period (L. M. P.) could the
obstetrician be reasonably confident about the expected time for delivery
(expected date of delivery E.D.D).
- Knowing the dates is critical either when there is a possible need to induce
labour, plan an elective Caesarean section or stop premature labour.
- Periods may be delayed or irregular for a few months after stopping Logynon, reducing the accuracy of determining dates in
a pregnancy.
- Ultrasound, which has been available for more than thirty years, can be
reasonably accurate in the first half of pregnancy in determining dates usually
overcoming this potential difficulty.
There is some evidence that folic acid supplementation reduces the risk
of the spina bifida group of defects when taken before pregnancy and for a
few weeks after conception. We now recommend folic acid supplements to all
women contemplating pregnancy.
