I have been on proscar 1 mg for about two weeks. No problems at all until yesterday when i began to feel my heart beat hard. It has done this before especially when i was on minoxidil. Also i have an anxiety disorder and i would sometimes get this feeling but it would go away quickly. I dont know if his is in my head but i do not want to get off the propecia. The beats are slightly uncomfortable and nothing unbearable. Also i suddenly quit taking my anxiety medication for 5 days and started back up today. I hought the beats wold go away since i took it today but hey are hitting hard right now. Do you think i cold stay on the propecia? My dermatologist said to get off the proscar until i take my anxiety meds again and get my body back to normal and then get back on the proscar. He also said he has never had a patient with heart problems from propecia. Also my heart rate is fine, but i can feel it more than usual.
