What is testosterone topical?

Testosterone topical (for the skin) is used as hormone replacement therapy in adult men with certain medical conditions that cause low or no testosterone levels.

Testosterone will not enhance athletic performance and should not be used for that purpose.

Testosterone is not approved for use in women or in men with low testosterone levels due to getting older.

Testosterone may also be used for purposes not listed in this medication guide.

Testosterone topical side effects

Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Testosterone can increase your risk of blood clots, stroke, or heart attack. Get emergency medical help if you have: chest pain, pain, swelling or warmth in your leg, sudden numbness or weakness on one side of the body, slurred speech, feeling short of breath, or trouble breathing.
