Alpha Blocker Drugs
e.g Tamsulosin or Alfuzosin
These medicines help to relax muscle in the prostate & open out the prostate to improve flow rate & bladder emptying. Side effects can include dizziness & dry orgasm.
5 AlphaReductase Inhibitors
e.g Finasteride or Dutasteride
These are the only drugs that can reduce the size of the prostate & can help to reduce disease progression & the risk of becoming unable to pass urine (retention). However there can be side effects such as decreased libido & erection problems. The PSA level will be approximately halved by either of these drugs.
