  • Keen Testosterone Spray Rx (testosterone spray) is available in 10mg, 15mg, and 20mg doses. It is a controlled substance (Schedule III), available by prescription only, used to treat adult males who have low or no testosterone due to certain medical conditions.

  • Tell your healthcare provider about all medical conditions including breast cancer, prostate cancer, urinary problems, heart, kidney, or liver problems, or sleep apnea. Share all medications you take including blood thinners, insulin, and corticosteroids.

  • Secondary Exposure to Testosterone — Women and children should avoid contact with any unwashed or unclothed area where Keen Testosterone Spray Rx has been applied, particularly just after application when the skin is still wet. Once dry, the risk is believed to be minimal. Direct exposure may result in unwanted signs of testosterone, such as increased body hair, deepened voice, or other symptoms. In the event of exposure, immediately wash the affected area with soap and water.

    Early signs and symptoms of puberty have occurred in young children who have come in direct contact with testosterone gels and creams by touching areas where men have used other topical testosterone products. Signs and symptoms may include enlarged penis or clitoris, early growth of pubic hair, erections or increased sex drive, behavior problems including aggression, changes in body hair, and increased acne.

    To lower the risk of transfer:


    • Apply to clean, dry skin on the inner arm or thigh only, as directed by your healthcare provider.
    • Avoid areas that may come into contact with others (e.g., hands or neck).
    • Prevent women and children from touching application sites until the spray is dry.
    • Wash your hands immediately after application.
    • Keep out of reach of children.
    • After the spray has dried, cover the application area with clothing. Keep the area covered until you have washed the application area well or have showered.
    • If you expect to have skin-to-skin contact with another person, first wash the application area well with soap and water.
    • Store in a cool, dry place away from direct sunlight.

    Stop using Keen Testosterone Spray Rx and call your healthcare provider right away if you see any signs and symptoms of puberty in a child, or changes in body hair or increased acne in a woman, that may have happened through accidental touching of the application area.

    Do not use Keen Testosterone Spray Rx if you:


    • Have breast or prostate cancer — testosterone therapy is contraindicated in men with these conditions.
    • Have allergies to any components of the spray.
    • Are a pregnant or breastfeeding woman — exposure to testosterone can cause harm to an unborn or breastfeeding baby. Women who are pregnant or may become pregnant should avoid contact with the spray.

    Before using, tell your healthcare provider about all of your medical conditions, including if you have breast cancer, prostate cancer, urinary problems due to an enlarged prostate, heart, kidney, or liver problems, or problems breathing while you sleep (sleep apnea). Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Especially tell your healthcare provider if you take insulin, medicines that decrease blood clotting (blood thinners), or corticosteroids.

  • Testosterone can cause serious side effects, including:

    • If you already have an enlargement of your prostate gland, your signs and symptoms can get worse while using Keen Testosterone Spray Rx (including changes in urination). Do not use without consulting your physician.

    • In large doses, Testosterone hormone replacement therapies may lower your sperm count.

    • Enlarged or painful breasts.

    • Having problems breathing while you sleep (sleep apnea).

    You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
