General Information On Prometrium

Prometrium or progesterone is an oral medication used for causing menstrual periods in women who have not reached the age of menopause but are not getting their periods due to lack of the hormone in their body. This drug can also be used for preventing overgrowth of the uterus lining in post-menopausal women who are going through estrogen hormone replacement therapy (HRT). Sometimes, your doctor may advise you to buy Prometrium in order to ensure a safe pregnancy.

Side Effects for Prometrium

Nausea, headache, breast tenderness, bloating, changes in vaginal discharge, dizziness, blurred vision, drowsiness and mood swings are common side effects of the drug. Most of these symptoms diminish on their own, but if they don’t, you should call your doctor and seek help. If you are experiencing some serious side effects of the drug such as unusual vaginal bleeding, depression, frequent and painful urination, dark patches on the face or skin, yellowing of the skin and eyes, dark urine, unusual tiredness, and breast lumps, then stop taking the medicine immediately and talk to your doctor. Seek immediate medical help if you experience pain in the chest, jaw or left arm, weakness on one side of the body, bulging eyes, loss of vision, double vision, slurred speech, fainting, coughing up blood, calf pain or swelling, and have trouble breathing.

Precautions

Some forms of Prometrium may contain peanut oil, and you should not use it if you are allergic to peanuts. You should also not take this medicine if you have a history of breast cancer, liver disease or if you have had a stroke, internal blood clots, or a heart attack in the previous year. The drug is given only for short periods of time like 6 to 12 days during your menstrual cycles, and so, you need to pay attention to your dosing schedule and never miss a dose. You should also not take Prometrium if you have heart disease, high blood pressure, high cholesterol, are overweight, suffer from migraine, asthma, seizure, epilepsy, diabetes, or if you smoke regularly. Smoking and alcohol intake may worsen the side effects of the drug, and therefore, it would be better to quit these habits as long as you are on Prometrium treatment.

Prometrium Dosage

You can buy Prometrium in 100 and 200mg strengths. If you are using the medicine for prevention of endometrial hyperplasia, then you should take one Prometrium 200mg capsule for 12 days in a row within a 28-day cycle at bed time. However, if you are using it to treat secondary amenorrhea, then take Prometrium 400mg for 10 days at bed time. If you are experiencing problems in swallowing the capsules, then you should take it in a standing position with a glass of water.

Interactions

Before taking Prometrium, you should tell your doctor about all the prescription and non-prescription drugs you are using at present, especially drugs that affect liver enzymes like Rifampin, azole antifungals like Itraconazole, anti-seizure medicines like Carbamazepine, Phenytoin, and Phenobarbital. As Prometrium can affect the results of some laboratory tests, you should inform the laboratory staff that you are using this medicine so that they can make the required changes.
