- If you have any condition affecting the womb lining, such as a leiomyoma (benign tissue tumour), endometriosis (presence of womb lining tissue outside the womb) or have had endometrial hyperplasia (excessive growth of the womb lining).
- If you have a history of blood clots (thrombosis) or have risk factors for blood clots (these risk factors and symptoms for a blood clot are listed in section “Blood clots”).
- If any of your immediate family has had cancers related to estrogen (endometrial cancer).
- If you have a liver disorder such as liver adenoma (a benign tumour).
- If you have a kidney or heart disorder.
- If you have diabetes or gallstones.
- If you have epilepsy (fits) or asthma.
- If you have migraine or severe headache.
- If you have systemic lupus erythematosus (SLE, autoimmune collagen disease, which may affect many organ systems).
- If you have high levels of fat in your blood (hypertriglyceridemia).
- If you have otosclerosis (hearing loss sometimes linked to pregnancy).
- You are on treatment for depression.

Estrogen containing medicines, including Estrofem ®, may cause mood changes and depression, which may be severe. Severe depression is associated with a higher risk of suicidal thoughts/behaviour (e.g. talking about suicide, withdrawing from social contact, having mood swings, being preoccupied with death or violence, feeling hopeless about a situation, increasing use of alcohol/drugs, doing self-destructive things, personality changes) and suicide. Contact your doctor in case of mood changes and depressive symptoms, including shortly after beginning treatment of Estrofem ®.
If you need a blood test, tell your doctor that you are taking Estrofem ®, since estrogen can affect the results of certain laboratory tests. If you are going to have surgery, talk to your doctor. You may need to stop taking these tablets 4 to 6 weeks before the operation, to reduce the risk of a blood clot. Your doctor will tell you when you can start treatment again.
Stop taking Estrofem ® If you are experiencing any of the following conditions below, stop taking Estrofem ®, and contact your doctor immediately:
- If you get a migraine-type headache for the first time.
- If you develop yellow skin or eyes (jaundice) or other liver problems.
- If you have symptoms of significant increase in blood pressure (e.g. headache).
- If you become pregnant.
- If any of the conditions listed contraindications “Do not take Estrofem ®” occur.
Medical check-ups
Before you start taking Estrofem ®, your doctor should ask about your own and your family’s medical history. Your doctor may decide to examine your breasts and/or your abdomen, and may do an internal examination - but only if these examinations are necessary for you, or if you have any special concerns. Once you have started on Estrofem ®, you should see your doctor for regular check-ups (at least once a year). At these check-ups, your doctor may discuss with you the benefits and risks of continuing to take Estrofem ®.
Be sure to:
- Go for regular breast screening and cervical smear tests.
- Regularly check your breasts for any changes such as dimpling of the skin, changes in the nipple, or any lumps you can see or feel. Additionally, you are advised to join mammography screening programs when offered to you. For mammogram screening, it is important that you inform the nurse/health care provider who is actually taking the x-ray that you use Estrofem ®, as this medicine may increase the density of your breasts which may affect the outcome of the mammogram. Where the density of the breast is increased, mammography may not detect all lumps.
Safety of HRT
As well as benefits, Estrofem ® has some risks which you need to consider when you’re deciding whether to take it or whether to carry on taking it.
