Hytrin

Generic name: Terazosin

Usage of Hytrin

Hytrin is in a group of drugs called alpha-adrenergic blockers. Hytrin relaxes your veins and arteries so that blood can more easily pass through them. It also relaxes the muscles in the prostate and bladder neck, making it easier to urinate.

Hytrin is used to treat hypertension (high blood pressure), or to improve urination in men with benign prostatic hyperplasia (enlarged prostate).

Hytrin may also be used for other purposes not listed in this medication guide.
