What is the dosage and how should it be used?


Terazosin comes as a capsule to be taken orally.

It is usually taken with or without food once a day at bedtime or twice a day (morning and evening). Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

Take terazosin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will start you on a low dose of terazosin and gradually increase your dose. If you stop taking terazosin for a few days or longer, your doctor will have to start you again on the lowest dose and gradually increase your dosage.

Terazosin controls high blood pressure and the symptoms of BPH but does not cure them. It may take 4 to 6 weeks or longer before you feel the full benefit of terazosin for BPH. Continue to take terazosin even if you feel well and never stop taking terazosin without first talking to your doctor.


The dose of terazosin will vary depending on the patient. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of terazosin. If your dose is different, do not change it unless your doctor tells you to do so.

The number of tablets that you take depends on the strength of the medicine.
