General Information and Indications:
Terazosin is used to treat the symptoms
of an enlarged prostate (benign prostatic hyperplasia or BPH), which include
difficulty in urination (hesitation, dribbling, weak stream, and incomplete
bladder emptying), painful urination, and urinary frequency and urgency. It
also is used alone or in combination with other medications to treat high
blood pressure. Terazosin is in a class of medications called
alpha-blockers. It relieves the symptoms of BPH by relaxing the muscles of
the bladder and prostate. It lowers blood pressure by relaxing the blood
vessels so that blood can flow more easily through the body.
Information For Users:
Terazosin comes as a capsule to take by mouth. It is
usually taken with or without food once a day at bedtime or twice a day.
Follow the directions on your prescription label, ask your doctor or
pharmacist If you have any questions. Take terazosin exactly as directed. Do
not take more or less of it or take it more often than prescribed by your
health care provider.
Your doctor will start you on a low dose of terazosin and slowly 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 slowly increase
your dose.
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 taking terazosin even if you feel
well. Do not discontinue taking terazosin without informing your doctor.
