I have severe social anxiety disorder and depression and consulted a psychiatrist for this, she prescribes me to pexep cr 12.5 mg once a day in night and beta cap tr in morning. I am taking this from 20 days now I got problem with this medication in my sexual life, sexual dysfunction, ed. I didn't have any history of sexual problem in past. How can I manage this I am thinking of stopping using this antidepressants and switch to natural ways, like dl-phenylanaline, 5 -htp supplements.
