These medicines are available in pill form. A low dose is used at first, then the dosage is gradually increased until the medicine has the greatest effect on reducing symptoms with minimal side effects.
These medicines relax the muscles in the prostate and at the base of the bladder. This reduces muscle tightness and spasms that may prevent normal urine flow.
These medicines may be used to treat symptoms of chronic prostatitis/pelvic pain syndrome, noninflammatory, a type of prostatitis, when muscle tightness and spasms are suspected to be the cause of symptoms and pain. Muscle tightness and spasms may force urine into the prostate, causing irritation that leads to prostatitis.
Most men who take alpha-blockers for prostatitis have fewer symptoms, but it takes awhile for the medicine to give results. Alpha-blockers work best in men who haven't already tried many different kinds of medicines for prostatitis and who have moderate to severe symptoms.1
Alpha-blockers can reduce blood pressure to less than normal. This can result in lightheadedness, especially when you stand up abruptly after sitting or lying down (postural hypotension).
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
Because this medicine can cause lightheadedness, it may be given at night and started at a low dose that will be gradually increased.
