    Hytrin (Terazosin) Dosage and Side Effects

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

    Proper Use of this medication

    Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

    Your doctor may occasionally change your dose to make sure you get the best results.

    HYTRIN lowers blood pressure and may cause dizziness or fainting, especially when you first start taking it, or when you start taking it again. You may wish to take this medication only at bedtime if it causes you to feel light-headed. Call your doctor if you have severe dizziness or feel like you might pass out.

    You may feel very dizzy when you first wake up. Be careful when standing or sitting up from a lying position.

    If you stop taking HYTRIN for any reason, call your doctor before you start taking it again. You may need a dose adjustment.

    Your blood pressure or prostate will need to be checked often. Visit your doctor regularly.

    If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

    Some things can cause your blood pressure to get too low. This includes vomiting, diarrhea, heavy sweating, heart disease, dialysis, a low-salt diet, or taking diuretics (water pills). Tell your doctor if you have a prolonged illness that causes diarrhea or vomiting.

    Store at room temperature away from moisture, heat, and light.

    Seek emergency medical attention or call the Poison Help line.

    Overdose symptoms may include extreme dizziness or fainting.

    Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

    If you miss your doses for several days in a row, contact your doctor before restarting the medication. You may need a lower dose.
