I Have Been Prescribed Pamsvax Xl And Finesteride By My

I have been prescribed pamsvax xl and finesteride by my gp for fairly mild swollen prostate problems - frequent need to urinate. I've been taking them for 3 weeks and am concerned about the side effects of erectile dysfunction and ejaculation disorders. Also read on Internet that should not drink alcohol with pans ax although doctor did not mention this. I do not feel inclined to continue with this medication. What do you suggest?
