Testim Gel: Uses, Dosage, Side Effects, Precautions and Alternates product

Quick overview

Testim Gel contains testosterone, a naturally occurring male hormone, and belongs to the androgens drug class. It is a topical gel used for testosterone replacement therapy in adult men with low or absent natural testosterone. Testim delivers testosterone through the skin into the bloodstream, helping restore and maintain hormone levels over 24 hours.

What is Testim Gel

Testim is a topical gel that contains testosterone, a naturally occurring male hormone. It is used to treat conditions in men caused by a lack of natural testosterone.

Testim Gel uses

  • Testosterone replacement therapy in adult men with low or absent natural testosterone (hypogonadism)
  • Primary hypogonadism caused by problems with the testicles (such as undescended testicles, testicular injury, certain genetic conditions, or damage from chemotherapy, alcohol, or heavy metals)
  • Hypogonadotropic hypogonadism caused by problems with the pituitary gland or hypothalamus that lead to low hormone signals to the testicles

Benefits of Testim Gel

  • Helps treat low testosterone levels (male hypogonadism) when confirmed by a doctor
  • Helps improve energy, mood, and general well-being in men with testosterone deficiency
  • Can help improve sex drive and sexual function when low testosterone is the cause
  • Helps support muscle mass and strength
  • Helps maintain bone density and normal male sexual characteristics

How Testim Gel works

Testim delivers testosterone through the skin into the bloodstream. The skin acts like a reservoir, slowly releasing the hormone over 24 hours, which helps raise and maintain testosterone levels in the blood.

Testim Gel dosage

Apply once daily, preferably in the morning, to clean, dry, unbroken skin of the shoulders and/or upper arms. Only apply to the area that would be covered by a short-sleeve T-shirt. Do not apply to the abdomen, genitals, or scrotum. Squeeze the entire contents of the tube into your palm and apply immediately. Let the application site dry for a few minutes before getting dressed. Wash your hands thoroughly with soap and water right after applying. Cover the application site with clothing once the gel has dried. Wash the application site with soap and water before any expected skin-to-skin contact with another person. Avoid showering, swimming, or bathing for at least 2 hours after applying. Avoid fire, flame, or smoking until the gel has fully dried, since it is flammable while wet. Use at the same time each day to help you remember.

If you miss a dose, apply it as soon as you remember, but if it is almost time for your next dose, skip the missed one and do not double up. This medicine should not be used by women. Safety and effectiveness have not been established in males younger than 18 years.
