Prometrium

Pronounced: pro-ME-tree-um
Generic name: Progesterone

Why is Prometrium prescribed?

Prometrium is prescribed for postmenopausal women who are taking estrogen (hormone replacement therapy); it prevents a buildup of the lining of the uterus and abnormal bleeding. Prometrium also may be prescribed to restore menstruation if your menstrual periods have stopped.

Most important fact about Prometrium

Prometrium increases the risk of blood clots, which can lead to phlebitis, breathing problems, vision problems, or stroke. If you experience any symptoms that might suggest the onset of a clot-related disorder--pain with swelling, warmth, and redness in a leg vein, coughing or shortness of breath, loss of vision or double vision, migraine, or weakness or numbness in an arm or leg--stop taking Prometrium and see your doctor immediately.

How should you take Prometrium?

Take Prometrium as directed by your doctor. If Prometrium is prescribed to prevent abnormal buildup of the uterine lining, you will take it once a day for 12 days in a 28-day cycle. If it is prescribed to treat missed menstrual periods, you will take it for 10 days. Prometrium is taken in the evening.

--If you miss a dose...

Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.

--Storage instructions...
