side effects from tamsulosin and finasteride
Finasteride has certain side effects, one of which is erectile dysfunction. Even small amounts of finasteride can cause this side effect. Other medication for an enlarged prostate to minimize urinary frequency include tamsulosin. You can try Flomax or Urotel and see how you respond to these agents which work at the bladder level.
In answer to your question James, I was on Tamsulosin for several years and suffered no serious side effects other than a reduction in ejaculate, a slight lowering of BP and pinpoint pupils.
