Methyltestosterone

Pronounced

"METH-ill-tess-TOSS-ter-own"

Common brand names:

Virlone

Uses

This medication is used in men who do not make enough of a natural substance called testosterone. In males, testosterone is responsible for many normal functions, including growth and development of the genitals, muscles, and bones. It also helps cause normal sexual development (puberty) in boys. Methyltestosterone is similar to the natural testosterone produced by your body. It belongs to a class of drugs known as androgens. It works by affecting many body systems so that the body can develop and function normally.

Methyltestosterone may also be used in certain adolescent boys to cause puberty in those with delayed puberty. It may also be used to treat certain types of breast cancer in women.

How to Use This Medication

Take this medication by mouth with or without food as directed by your doctor, usually 1 to 4 times a day. The dosage is based on your medical condition, testosterone blood levels, and response to treatment.

Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day.

Misuse or abuse of testosterone or testosterone-like products can cause serious side effects such as heart disease (including heart attack), stroke, liver disease, mental/mood problems, abnormal drug-seeking behavior, or improper bone growth (in adolescents). Do not increase your dose or use this drug more often or for longer than prescribed. When testosterone is misused or abused, you may have withdrawal symptoms (such as depression, irritability, tiredness) when you suddenly stop using the drug. These symptoms may last from weeks to months.

Tell your doctor if your condition does not improve or worsens.
