BEFORE YOU TAKE CERAZETTE
Cerazette, like other hormonal contraceptives, does not protect against HIV infection AIDS) or any other sexually transmitted disease.
Do not take Cerazette if:
- if you are allergic to any of the ingredients of Cerazette.
- if you have a thrombosis. Thrombosis is the formation of a blood clot in a blood vessel (e.g. of the legs (deep venous thrombosis) or the lungs (pulmonary embolism)).
- if you have or have had jaundice (yellowing of the skin) or severe liver disease and your
- liver is still not working normally.
- if you have or if you are suspected of having a cancer that grows under the influence of sex-steroids, such as certain types of breast cancer.
- if you have any unexplained vaginal bleeding.
- If any of these conditions apply to you, tell your doctor before you start to use Cerazette. Your doctor may advise you to use a non-hormonal method of birth control.
- If any of these conditions appear for the first time while using Cerazette, consult your doctorimmediately.
Take special care with Cerazette
Before you start Cerazette tell your doctor or Family Planning Nurse, if
- you have ever had breast cancer.
- you have liver cancer, since a possible effect of Cerazette cannot be excluded.
- you have ever had a thrombosis.
- you have diabetes.
- you suffer from epilepsy (see section ‘Taking other medicines’).
- you have tuberculosis (see section ‘Taking other medicines’).
- you have high blood pressure.
- you have or have had chloasma (yellowish-brown pigmentation patches on the skin, particularly of the face); if so, avoid too much exposure to the sun or ultraviolet radiation.
When Cerazette is used in the presence of any of these conditions, you may need to be kept under close observation. Your doctor can explain what to do.
- It is important to regularly check your breasts and you should contact your doctor as soon as possible if you feel any lump in your breasts.
- Breast cancer has been found slightly more often in women who take the Pill than in women of the same age who do not take the Pill. If women stop taking the Pill, this reduces the risk, so that 10 years after stopping the Pill, the risk is the same as for women who have never taken the Pill.
Breast cancer is rare under 40 years of age but the risk increases as the woman gets older. Therefore, the extra number of breast cancers diagnosed is higher if a woman continues to take the Pill when she is older. How long she takes the Pill is less important.
- In every 10 000 women who take the Pill for up to 5 years but stop taking it by the age of 20, there would be less than 1 extra case of breast cancer found up to 10 years after stopping, in addition to the 4 cases normally diagnosed in this age group.
- In 10 000 women who take the Pill for up to 5 years but stop taking it by the age of 30, there would be 5 extra cases in addition to the 44 cases normally diagnosed.
- In 10 000 women who take the Pill for up to 5 years but stop taking it by the age of 40, there would be 20 extra cases in addition to the 160 cases normally diagnosed.
The risk of breast cancer in users of progestogen-only pills like Cerazette is believed to be similar to that in women who use the Pill, but the evidence is less conclusive.
Breast cancers found in women who take the Pill, seem less likely to have spread than breast cancers found in women who do not take the Pill. It is not certain whether the Pill causes the increased risk of breast cancer. It may be that the women were examined more often, so that the breast cancer is noticed earlier.
See your doctor immediately if you notice possible signs of a thrombosis (see also ‘Regular check-ups’).
Thrombosis is the formation of a blood clot, which may block a blood vessel. A thrombosis
sometimes occurs in the deep veins of the legs (deep venous thrombosis). If this clot breaks away from the veins where it is formed, it may reach and block the arteries of the lungs, causing a so-called “pulmonary embolism”. A pulmonary embolism can cause chest pain, breathlessness, collapse or even death.
- Deep venous thrombosis is a rare occurrence. It can develop whether or not you are taking the Pill. It can also happen if you become pregnant. The risk is higher in Pill-users than in non-users. The risk with progestogen-only pills like Cerazette is believed to be lower than in users of Pills that also contain oestrogens (combined Pills).
POSSIBLE SIDE EFFECTS:
Like all medicines, Cerazette can cause side effects, although not everybody gets them.
Tell your doctor if you notice any unwanted effect, especially if severe or persistent.
Vaginal bleeding may occur at irregular intervals while using Cerazette. This may be just
slight staining which may not even require a pad, or heavier bleeding, which looks rather like a scanty period. You may need to use tampons or sanitary towels. You may also not have any bleeding at all. Irregular bleeding is not a sign that Cerazette is not working. In general, you need not take any action; just continue to take Cerazette. If bleeding is heavy or prolonged you should consult your doctor.
How often are other possible side effects seen?
Common (affecting less than 1 in 10 women): mood changes, depressed mood, decreased sexual drive (libido), headache, nausea, acne, breast pain, irregular or no periods, weight increase. Uncommon (affecting less than 1 in 100 women) infection of the vagina, difficulties in wearing contact lenses, vomiting, hair loss, painful periods, ovarian cysts, tiredness. Rare (affecting less than 1 in 1000 women) skin conditions such as: rash, hives, painful blue-red skin lumps (erythema nodosum)
Apart from these side effects, breast secretion or leakage may occur.
You should see your doctor immediately if you experience symptoms of angioedema, such as
(i) swollen face, tongue or pharynx;
(ii) difficulty to swallow; or
(iii) hives and difficulties to breathe.
