Thrombosis and the Pill

Thrombosis is the formation of a blood clot that may block a blood vessel.

Thrombosis sometimes occurs in the deep veins of the legs (deep venous thrombosis (DVT)). If a blood clot breaks away from the veins where it has formed, it may reach and block the arteries of the lungs, causing pulmonary embolism (PE).

Blood clots are a rare occurrence and can develop whether or not you are taking an oral contraceptive. They can also happen during Pregnancy. The risk of having blood clots is higher in OC users than in non users, but not as high as during Pregnancy.

Therefore, one should keep the possibility of an increased thromboembolic risk in mind, particularly where there is a history of thromboembolic diseases.

If you notice possible signs of a thrombosis, stop taking Microlut and consult your doctor immediately.

Cancer and the Mini-pill

Breast cancer has been diagnosed slightly more often in women who use the Mini-pill than in women of the same age who do not use the Mini-pill. This slight increase in the numbers of Breast cancer diagnoses gradually disappears during the course of the 10 years after women stop using the Mini-pill.

It is not known whether the difference is caused by the Mini-pill. It may be that these women were examined more often, so that the Breast cancer was noticed earlier.

In rare cases benign liver tumours and, even more rarely, malignant liver tumours have been reported in users of the Mini-pill. These tumours may lead to internal bleeding. Contact your doctor immediately if you have severe pain in your abdomen.

Cervical cancer has been reported to occur more often in women who have been using the Mini-pill for a long time. This finding may not be caused by the Mini-pill, but may be related to sexual behaviour and other factors.
