Many drugs can cause breast growth and pain in men. That
includes any estrogen hormone drug and any androgen blocker
(eg.,spironolactone). Certain hair growth drugs (eg., finasteride,
dutasteride) would be included.
In some cases, the affected men are not the ones taking the
medication. For instance, couples occasionally misuse estrogen
cream as personal lubricants.
