Gynecomastia associated with calcium channel blocker therapy. 1988

Division of Epidemiology and Surveillance, Food and Drug Administration, Rockville, Md.

Gynecomastia is a reaction that is not usually associated with calcium channel blocker therapy. The Division of Epidemiology and Surveillance, within the US Food and Drug Administration (Rockville, Md), has received 31 reports of gynecomastia occurring after the use of these drugs. The underlying mechanism of this reaction is unknown, although two patients did report elevated prolactin levels. Gynecomastia developed in two patients, resulting in the surgical removal of the breast and/or nodules before discontinuation of drug therapy. The possibility of an association between calcium channel blockers and gynecomastia should be considered before an extensive workup or surgical procedure is undertaken.
