TERAZOSIN HYDROCLORIDE DEHYDRATE

Terazosin belongs to a class of drugs called alpha blockers, which relax certain muscles and help small blood vessels remain open. Alpha blockers work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure. Because alpha blockers also relax other muscles throughout the body, these medications can help improve urine flow in older men with prostate problems.

Uses

Treatment of hypertension and benign prostatic hyperplasia (BPH).

Warnings

You should not use this medication if you are allergic to terazosin.

If you have a history of prostate cancer, you may need a dose adjustment or special tests to safely take terazosin.

Terazosin can affect your pupils during cataract surgery. Tell your eye surgeon ahead of time that you are using this medication. Do not stop using terazosin before surgery unless your surgeon tells you to.
