Testosterone Warnings

The U.S. Food and Drug Administration (FDA) requires makers of prescription testosterone products to have a label stating that:

• taking testosterone may cause heart attacks, strokes and death, and

• it is approved only for men who have low testosterone levels due to disorders of the testicles, pituitary gland, or brain, that cause lack of sexual function or desire. In June 2014, the FDA began requiring a warning about increased risk for venous blood clots, including deep vein thrombosis and pulmonary embolism that can kill you.

These warnings are needed because testosterone is being used extensively by men and women to treat symptoms caused by natural aging, such as decreased sexual desire and loss of muscle size and strength.

Testosterone in Europe There is still controversy about the safety of testosterone because many studies have failed to show any damage. In November 2014, a regulatory body representing European Union members concluded that there is "no consistent evidence" of an increased risk for heart problems with testosterone products.

You can decide for yourself whether to use testosterone, but the FDA has advised, "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."
