TERAZOSIN CAPSULE - ORAL

(teh-RAY-zoh-sin)

COMMON BRAND NAME(S): Hytrin

USES: Terazosin is used alone or in combination with other drugs to treat high blood pressure. It works by relaxing blood vessels so blood can flow more easily. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

This medication is also used to treat an enlarged prostate (benign prostatic hyperplasia or BPH) in men. Terazosin does not shrink the prostate, but it helps relax the prostate and bladder neck muscles to improve urine flow and emptying of the bladder. It also reduces other symptoms such as excessive urination at night.

Terazosin belongs to a class of medications called alpha-blockers.

HOW TO USE: Take this medication by mouth, usually once daily at bedtime or as directed by your doctor. If stomach upset occurs, you may take it with food or milk.

Dosage is based on your medical condition, use of other medications, and response to therapy.

If you are taking this drug for the first time, do not take more than 1 milligram to start. To avoid injury related to dizziness or fainting, take your first dose of terazosin at bedtime. Your dose may be gradually increased. You should take your first new dose at bedtime when your dose is increased unless directed otherwise by your doctor.

Take this medication regularly in order to get the most benefit from it. Remember to take it at the same time each day as directed.

Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased. If you have not taken this medication for several days, consult your doctor or pharmacist before restarting it. Follow your doctor's instructions carefully.

If you are taking this medication for high blood pressure, it is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Inform your doctor if your routine blood pressure readings increase.

If you are taking this drug for an enlarged prostate, it may take four to six weeks before you notice the full benefit of the drug. Inform your doctor if your condition persists or worsens.

SIDE EFFECTS: Fatigue, nausea, drowsiness, blurred vision, headache, or stuffy nose may occur. Lightheadedness or dizziness upon standing may also occur, especially after the first dose, and shortly after taking the drug during the first week of treatment. To minimize dizziness and the risk of fainting, get up slowly when rising from a seated or lying position. If dizziness occurs, sit or lie down. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur: fainting, fast/irregular heartbeat, burning/tingling in the hands/feet, sexual function problems, swelling of the ankles/hands/feet, unexpected weight gain.

Tell your doctor immediately if any of these rare but serious side effects occur: easy bruising/bleeding, mental/mood changes.

For males, in the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and seek immediate medical attention, or permanent problems could occur.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
