terazosin

By Abbott Laboratories

What is this medication for?

Terazosin belongs to the class of medications known as alpha-receptor blockers. It is used to treat high blood pressure. It relaxes blood vessels, allowing blood to flow through them more easily. It may be used alone or together with other medications for high blood pressure.

Terazosin is also used to treat enlarged prostate (benign prostatic hypertrophy or BPH). For BPH, terazosin helps to relax the muscles in the prostate and bladder. This helps to improve urine flow and decrease symptoms of BPH. Terazosin does not slow or stop the progression of enlarged prostate.
