What is Fortesta?
Fortesta gel is a prescription medicine that contains testosterone.
Testosterone is a naturally occurring male hormone necessary for many processes in the body.
Fortesta gel is used to treat conditions in men that result from a lack of natural testosterone.
Fortesta will not enhance athletic performance and should not be used for this purpose.
Fortesta gel should not be used by a woman. Testosterone can cause birth defects in an unborn baby. A pregnant woman should avoid coming into contact with Fortesta gel, or with a man's skin areas where the gel has been applied. If contact does occur, wash with soap and water right away.
Topical testosterone is absorbed through the skin and can cause side effects or symptoms of male features in a child or woman who comes into contact with Fortesta. Call your doctor if a person who has close contact with you develops enlarged genitals, premature pubic hair, increased libido, aggressive behavior, male-pattern baldness, excessive body hair growth, increased acne, irregular menstrual periods, or any signs of male characteristics.
Misuse of Fortesta can cause dangerous or irreversible effects. Never use more than your prescribed dose. Do not share this medicine with another person.
