[This information is an update to the FDA Drug Safety Communication: FDA Evaluating Risk of Stroke, Heart Attack, and Death with FDA-Approved Testosterone Products issued on January 31, 2014.]
[Posted 03/03/2015] ISSUE: FDA is requiring that the manufacturers of all approved prescription testosterone products change their labeling to clarify the approved uses of these medications. FDA is also requiring these manufacturers to add information to the labeling about a possible increased risk of heart attacks and strokes in patients taking testosterone. FDA cautions that prescription testosterone products are approved only for men who have low testosterone levels caused by certain medical conditions. The benefit and safety of these medications have not been established for the treatment of low testosterone levels due to aging, even if a man’s symptoms seem related to low testosterone.
Based on the available evidence from studies and expert input from an FDA Advisory Committee meeting (see http://www.fda.gov/AdvisoryCommittees/CommitteesMeetingMaterials/Drugs/ReproductiveHealthDrugsAdvisoryCommittee/ucm404895.htm ), FDA has concluded that there is a possible increased cardiovascular risk associated with testosterone use. These studies included aging men treated with testosterone. Some studies reported an increased risk of heart attack, stroke, or death associated with testosterone treatment, while others did not. See the Data Summary section of the FDA Drug Safety Communication at: http://www.fda.gov/Drugs/DrugSafety/ucm436259.htm for additional details.
BACKGROUND: Testosterone is FDA-approved as replacement therapy only for men who have low testosterone levels due to disorders of the testicles, pituitary gland, orbrain that cause hypogonadism. However, FDA has become aware that testosterone is being used extensively in attempts to relieve symptoms in men who have low testosterone for no apparent reason other than aging. The benefits and safety of this use have not been established.
RECOMMENDATION: Health care professionals should prescribe testosterone therapy only for men with low testosterone levels caused by certain medical conditions and confirmed by laboratory tests. Health care professionals should make patients aware of the possible increased cardiovascular risk when deciding whether to start or continue a patient on testosterone therapy. Patients using testosterone should seek medical attention immediately if symptoms of a heart attack or stroke are present, such as chest pain, shortness of breath or trouble breathing, weakness in one part or one side of the body, or slurred speech.

Testosterone topical products may cause harmful effects to people who touch your skin in the area where you applied the gel or solution. Women and children are especially likely to be affected if they touch skin that has been covered with testosterone topical products. If a pregnant woman touches skin that has been covered with testosterone topical products, her unborn baby may be harmed.
You must take precautions to be sure that others will not come into contact with testosterone gel or solution that is on your skin. After you apply testosterone gel or solution, you should allow the medication to dry for a few minutes and then put on clothing that completely covers the area so that no one will touch your bare skin. When you have finished applying the medication, you must wash your hands with soap and water to remove any medication that may be left on your hands.
Do not let anyone touch your skin in the area where you applied testosterone gel or solution. If you expect that you may have skin-to-skin contact with another person, you should wash the area very well with soap and water. If anyone touches skin that has been covered with testosterone gel or solution and has not been washed, that person should wash his or her skin with soap and water as soon as possible. You should also tell others to be careful when handling your clothing, bed linens, or other items that may have testosterone gel or solution on them.
If women or children touch skin that has been treated with testosterone products, they may develop certain symptoms. If a woman who may have come into contact with testosterone develops either of the following symptoms, she should call her doctor immediately: growth of hair in new places on the body or acne. If a child who may have come into contact with testosterone develops any of the following system, you should call the child's doctor immediately: enlarged genitals, growth of pubic hair, increased erections, increased sexual desire, and aggressive behavior. Most of these symptoms can be expected to go away after the child stops coming into contact with testosterone, but in some cases, genitals may remain larger than normal.
Testosterone topical may cause the bones to mature more quickly than normal in children who come into contact with the medication. This means that the children may stop growing sooner than expected and may have a shorter than expected adult height. Even if these children no longer come into contact with testosterone topical products, their bones may remain more mature than normal.
WHY is this medicine prescribed?
Testosterone topical is used to treat the symptoms of low testosterone in men who do not produce enough natural testosterone. Testosterone is in a class of medications called hormones. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. Symptoms of low testosterone include decreased sexual desire and ability, extreme tiredness, low energy, depression, and loss of certain male characteristics such as muscular build and deep voice. Testosterone topical works by replacing the testosterone that is normally produced by the body.
