Prasterone Vaginal

pronounced as (pras' ter one)

Why is this medication prescribed?

Vaginal prasterone is used to treat changes in and around the vagina due to menopause ("change of life," the end of monthly menstrual periods) that can cause painful sexual intercourse. Prasterone is in a class of medications called steroids. It works by replacing hormones that are normally produced in the body.

How should this medicine be used?

Vaginal prasterone comes as an insert to place in the vagina. It is usually used once a day at bedtime. Use vaginal prasterone at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use vaginal prasterone exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Vaginal prasterone comes with a special applicator to use to place the insert into your vagina. Your medication will come with instructions for use. Read these instructions and follow them carefully. Ask your doctor or pharmacist if you have any questions about how to use vaginal prasterone.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
