Drug Name

Hytrin (Terazosin)

Drug Uses

Hytrin is used to treat the symptoms of urinary obstruction as a result of an enlarged prostate. Hytrin relaxes the smooth muscles of the bladder neck, the prostate, and increases urine flow. Hytrin is also used alone or in combination with another blood pressure medication to treat high blood pressure.

How Taken

Take this medication exactly as prescribed. Try to take it at the same time each day. Take the first dose at bedtime to minimize the chances of getting dizzy or fainting. Tablets may be taken with food or milk to avoid stomach upset. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is abruptly stopped. Your dose may need to be gradually decreased.

Drug Class and Mechanism

Hytrin belongs to a class of medications, called alpha 1 blockers which relaxes the smooth muscles of the arteries, the prostate, and the bladder neck. Other alpha blockers in the same class of drugs include doxazosin (Cardura), alfuzosin (Uroxatral), tamsulosin (Flomax), and prazosin (Minipress). Relaxing the smooth muscles of the arteries lowers blood pressure. Relaxing the smooth muscles around the bladder neck relieves urinary obstruction, caused by an enlarged prostate (prostate hypertrophy).

Missed Dose

If you miss a dose, take as soon as remembered; do not take if it is almost time for the next dose, instead, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up. Contact your doctor if 2 or more consecutive doses are missed.

Storage

Store at room temperature away from sunlight and moisture.
