The cabergoline heart valve side effects only occur when it is used at 3mg daily for 6 months or more... a FAR cry from the .5 mg dosage that is occaisionally used for a comple weeks to a month for libido... just like any drug, if you take alot of it for a long time, side effects occur. Almost EVERY drug is like that. Take Alcohol for example... 1 or 2 glasses of red wine daily actually help you live LONGER (the French already know this... bastards

) But if someone was to drink red wine HEAVILY every day, obviously things will go to sh1t...
