I've been taking labetalol for 3 months now, 800 mg per day and now am experiencing excessive hair loss! Has anyone else noticed this while taking labetalol ? My cardiologist denies that this could be a side effect of labetalol. I do also take 3 other BP meds (micardis, clonidine and norvasc). I'd appreciate hearing from others who have experienced the same problem. Thank you!
