Warnings and precautions
Medical examination/follow-up: Before you start or re-start treatment with Novofem ®, a complete medical history of you and your family should be taken. During treatment, you are recommended to have periodic check-ups. You are encouraged to report any changes in your breasts to your doctor or nurse.
Be sure to:
- Go for regular 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.
If you notice any changes in your breast, make an appointment to see your doctor as soon as possible. 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 Novofem ®, as this medication 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.
If you get breakthrough bleeding or spotting, it is usually nothing to worry about, especially during the first few months of therapy. But if the bleeding or spotting:
- carries on for more than the first few months
- starts after you’ve been on Novofem ® for a while
- carries on even after you’ve stopped taking Novofem ®
make an appointment to see your doctor. It could be a sign that your endometrium has become thicker.
Ovarian cancer
Long-term (at least 5 years) use of HRTs, such as Novofem ®, has been associated with an increased risk of ovarian cancer in some epidemiological studies.
Breast cancer
Breast cancer has been diagnosed slightly more often in women who use HRT than in women of the same age who do not use HRT. This slight increase in the number of breast cancer diagnoses gradually disappears during the course of the 10 years after stopping use of HRT. When you are using Novofem ®, you must perform monthly breast self-examinations. Your doctor will advise you on when to report for breast examinations and any appropriate investigations.
Effects on your heart or circulation
Heart disease Novofem ® is not recommended for women who have heart disease, or have had heart disease recently. If you have ever had heart disease, talk to your doctor to see if you should be taking Novofem ®. Novofem ® will not help to prevent heart disease.
Stroke Recent research suggests that Novofem ® increases the risk of having a stroke. If you get:
- unexplained migraine-type headaches, with or without disturbed vision
see a doctor as soon as possible and do not take any more Novofem ® until your doctor says you can. These headaches may be an early warning sign of a stroke.
Blood clots
Novofem ® may increase the risk of blood clots in the veins (also called deep vein thrombosis, or DVT), especially during the first year of taking it. You are more likely to get a blood clot:
- if you use estrogen-containing medicines
- if you are of older age
- if you are seriously overweight
- if you have had a blood clot before
- if any of your close family have had blood clots
- if you have had one or more miscarriages
- if you are pregnant or you just had a baby
- if you have cancer
- if you have any blood clotting problem that needs treatment with a medicine such as warfarin
- if you’re off your feet for a long time because of major surgery, injury or illness
- if you have a rare condition called systemic lupus erythematosus. (a disease of the immune system that affects many organs of the body)
If any of the above-mentioned conditions apply to you, tell your doctor to see if you should take Novofem ®. If you get:
- painful swelling in your leg
- sudden chest pain
- difficulty breathing
see a doctor as soon as possible and do not take any more Novofem ® until your doctor says you can. These may be signs of a blood clot.
If you’re going to have surgery, make sure your doctor knows about it. You may need to stop taking Novofem ® about 4 to 6 weeks before the operation, to reduce the risk of a blood clot. Your doctor will tell you when you can start taking Novofem ® again.
It remains unclear if varicose veins play a role in VTE.
Other conditions you should be aware of:
- Novofem ® may cause fluid retention, so if you have heart or kidney problems you should be carefully observed by your doctor. If you suffer from kidney failure you should be closely observed since it is expected that the levels of circulating active ingredients in Novofem ® is increased.
- If you have asthma, epilepsy, or diabetes mellitus (high blood sugar) and these conditions have worsened during Novofem ® treatment, your need for Novofem ® should be reconsidered.
- If you are using Novofem ® and are postmenopausal there is an increased risk of surgically confirmed gallbladder disease If you have a family history of high levels of triglycerides (fat) in your blood (familial hypertriglyceridaemia) you should know that there have been cases of serious elevations of plasma triglycerides, leading to pancreatitis (acute or chronic inflammation of the pancreas) and other complications due to estrogen therapy like Novofem ®.
Conditions which need supervision
If you have (or have had) any of the following conditions, tell your doctor. Your doctor may want to follow you more closely. These conditions may come back or get worse during treatment with Novofem ®.
- Benign tumours of your womb (leiomyoma), deposition of uterine mucosa outside the womb (endometriosis), excessive growth of the womb lining (endometrial hyperplasia;
- History of venous thrombosis (blood clot formation) or embolisms (thromboembolic disorders) or presence of risk factors for such conditions;
- High blood pressure (hypertension);
- Liver disorders (e.g., liver adenoma - primary benign tumour of the liver);
- Diabetes with or without vascular involvement;
- Sudden hearing loss or otosclerosis;
- Migraine or (severe) headache;
- Systemic lupus erythematosus (autoimmune disease);
- Cholelithiasis (formation of stones in your gallbladder);
- Epilepsy fits) or asthma.
If you need a blood test, tell your doctor that you are taking Novofem ® as estrogen can affect the results. Tell your doctor before taking Novofem ® that:
- You are on treatment for depression.
- You have had depression with previous use of estrogen and/or progesterone/progestogen-containing medicines.
- You have a substance abuse problem.
- You have an underlying psychiatric disorder such as post-traumatic stress disorder or bipolar disorder.
- You have a family history of mental disorders.
- You have a history of physical or sexual abuse.
Estrogen and/or progesterone/progestogen containing medicines, including Novofem ®, 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.
