Quick overview
Fortesta Gel is a prescription medicine containing testosterone, a naturally occurring male hormone.

It is applied once daily to the front and inner thighs and is not intended to enhance athletic performance.
What is Fortesta Gel
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 Gel uses
- Treats low or absent natural testosterone in men caused by conditions such as primary hypogonadism (a testicular problem) or hypogonadotropic hypogonadism (a pituitary/hypothalamus problem)
- Not for use to enhance athletic performance
Benefits of Fortesta Gel
- Helps treat low testosterone levels (male hypogonadism) when confirmed by a doctor
- Helps restore testosterone to a more normal physiological range
- Can improve sex drive, energy, and overall well-being when symptoms are due to testosterone deficiency
- Helps support muscle mass and strength
- Helps maintain bone density and normal male sexual characteristics
How Fortesta Gel works
Testosterone is the natural male hormone. This medicine is absorbed through the skin, enters your bloodstream, and helps raise your body's testosterone back to normal levels, supporting male sexual characteristics and other body functions that depend on testosterone.
Fortesta Gel dosage
Use exactly as prescribed by your doctor and follow all directions on your prescription label; do not use more or less than prescribed or for longer than prescribed. Before using a new canister for the first time, prime the pump by pushing down on it several times and discarding the gel that comes out.
Apply the gel to clean, dry, intact skin of the front and inner thighs only; use one finger to rub it in evenly. Apply the gel in the morning; if you shower or bathe, apply the gel afterward. Only apply to skin that will be covered by shorts or pants, and avoid the area of the thigh next to the genitals. Let the application site dry completely before dressing, then wash your hands right away with soap and water.
Avoid swimming, showering, or bathing for at least 2 hours after applying the gel (some sources say 2 to 5 hours, so follow your specific product's directions). Cover treated skin with clothing to avoid getting the medicine on other people; if someone else touches a treated area, they should wash it right away with soap and water.
Do not apply to the penis, scrotum, or other parts of the body, and do not apply to broken or irritated skin. Do not let anyone else apply this medicine to your body, and do not share this medicine with another person. Use regularly at the same time each day to get the most benefit.
This medicine is flammable until dry; avoid smoking or being near open flames until it has fully dried on your skin. Not for use in anyone younger than 18 years old.
If you miss a dose, apply the gel as soon as you remember, but skip it if it is almost time for your next dose; do not double up.

- Because the gel is absorbed through the skin, it can pass to a child or woman who has close contact with treated skin, causing signs of male features. Call your doctor if this happens.

- This medicine can lower sperm count and may affect a man's ability to have children.
- This medicine should not be used by women, and pregnant women should avoid any contact with the gel or with skin where a man has applied it, because it can harm an unborn baby. If contact happens, wash the area with soap and water right away.
- This medicine is not meant for use in women, including breastfeeding women, and may cause serious problems in a nursing infant.
