The PRAC has completed an EU-wide review of testosterone-containing medicines following concerns over serious side effects on the heart and blood vessels, including heart attack. The PRAC review did not find consistent evidence that the use of testosterone in men who do not produce enough testosterone (a condition known as hypogonadism) increases the risk of heart problems. The committee considered that the benefits of testosteronecontinue to outweigh its risks but recommended that testosterone-containing medicines should only be used where lack of testosterone has been confirmed by signs and symptoms as well as laboratory tests.
