Terazosin
Uses of Terazosin
Terazosin is commonly used to treat Benign Prostatic Hyperplasia, Heart Failure, Hypertension, and Raynaud's Disease.
How Terazosin Works
Terazosin is classified as an alpha-blocker. It competitively inhibits postsynaptic alpha receptors. As a result, it relaxes the peripheral blood vessels and reduces blood pressure. Besides, it also relieves the symptoms of benign prostate hyperplasia by reducing the smooth muscle tone of the bladder outlet.

Hypotension, Drowsiness, Palpitations, Visual disturbance, Weight gain, Body ache, Tinnitus, Urinary incontinence
Warnings
Kidney Safe If Prescribed
No dosage adjustments needed for patients with renal insufficiency.
Alcohol Not Advisable
It is unsafe to consume alcohol with Terazosin. Taking Terazosin with alcohol may have worsened the additive effects of Terazosin such as headache, dizziness, lightheadedness, feeling of increased heartbeats and low blood pressure.
Pregnancy Not Safe
Terazosin may be unsafe to use during pregnancy. Animal studies have shown side effects on the fetus, however, there are limited human studies and the safety profile during pregnancy is not established. It should not be used unless the potential benefit outweighs the risk. Please consult your doctor.
Driving Not advisable
Do not drive unless you are feeling well. Terazosin may cause side effects such as dizziness, headches or syncope, all of which could affect the ability to concentrate and drive.
Liver Limited Data
Terazosin is metabolized extensively by the liver, therefore, dose adjustment is needed in individuals wiith impaired liver function. For patients with severe hepatic impairment, Terazosin usage is not recommended.
Lactation Limited Data
Excretion of Terazosin in breast milk is still not known and the safety profile is not established in lactating women. Hence, it is not recommended during breastfeeding.
