What are Premarin with Methyltestosterone (conjugated estrogens and methyltestosterone)?

Conjugated estrogens are female sex hormones necessary for many processes in the body.

Methyltestosterone is a naturally occurring androgen ("male" sex hormone) that is produced in the testes in men and, in small amounts, by the ovaries and the brain in women.

The combination, conjugated estrogens and methyltestosterone, is used to treat symptoms of menopause that have not responded to estrogen therapy alone. Most often, conjugated estrogens and methyltestosterone is used to treat the symptoms of menopause in women who also have diminished libido (a declining interest in sexual activity).

Conjugated estrogens and methyltestosterone may also be used for purposes other than those listed in this medication guide.

What is the most important information I should know about Premarin with Methyltestosterone (conjugated estrogens and methyltestosterone)?
