Here are some points to consider:
Though usually safe, progesterone may harm your baby in the womb. Avoid getting pregnant by using appropriate contraceptive measures. If you suspect of getting pregnant, inform your doctor immediately.
If you experience any of the followings, promptly discontinue this medicine and inform your doctor:
o Chest pain or pain in the calves o Breathing problems including sudden shortness of breath o A sudden, severe headache o Speech problems o A sudden loss of coordination o Vision problems
Your risk of breast cancer and endometrial (lining of the uterus) cancer is elevated by a slight margin. Inform your doctor about your family history of the cancers, if any.
Large doses of progesterone for prolonged time or using it along with an estrogen-containing medicine may make you more prone to heart attack, stroke, blood clots, or dementia. Consult your doctor if you are concerned. If you are a smoker and overweight with elevated blood cholesterol level, your risk is even more. Lower your risk by:
o Quitting smoking. o Keeping sugar and cholesterol levels down. o Maintaining a healthy weight.
You may need to avoid this medicine during a surgery (including dental surgery) or emergency treatment. Consult your doctor or dentist beforehand.
If you experience vision problems such as sudden vision loss during treatment with progesterone, discontinue immediately and consult your doctor.
Take special care while driving or using machines, as it might cause dizziness or drowsiness.
Progesterone may interfere with results of some laboratory tests. So, it’s better if you inform the doctor in charge about this.
