<p>Androgens should be used with caution in pre (pubertal) boys to avoid premature epiphyseal closure or precocious sexual development. Skeletal maturation should be monitored regularly. Patients with latent or overt cardiac failure, renal dysfunction, hypertension, epilepsy or migraine (or a history of these conditions) should be kept under close medical supervision, since aggravation or recurrence may occasionally be induced. Androgens should be used with caution in men suffering from benign prostatic hyperplasia. The use of steroids may influence the results of certain laboratory tests. The misuse of androgens to enhance ability in sports carries serious health risks and is to be discouraged.</p>
