Doctor i am 22 years old healthy male i only suffer from social anxiety no heart or other issue so the doctor prescribed me inderal propranolol beta blocker 40mg one tablet per day for my anxiety can i have sex and masturbate?

Good Q! Short ans: yes - sexual activity safe in that scenario Long ans: propranolol treats physical symptoms (sweating,tremors,increase heart rate/bp, palpitations, fright,etc) experienced resulting from anxiety. It does not prevent/ reduce actual anxiety. Try small doses (10mg) only taken if needed (PRN) up to 4x/day. No significant increased risk with sexual activity. Possible decreased libido.

you can. One of the side effects of b blockers is it may make it more difficult for you to achieve an erection.
