Terazosin is indicated for the treatment of benign prostatic hyperplasia (BPH) in men, specifically targeting the alleviation of related symptoms, such as difficulties in urination, painful urination, and increased urinary frequency and urgency. This medication can also be employed either as monotherapy or in combination with other drugs to manage hypertension.
Belonging to the class of alpha-blockers, terazosin exerts its therapeutic effects by inducing relaxation of the muscles in the bladder and prostate, leading to symptom relief in individuals with BPH. It aids in reducing blood pressure by relaxing the blood vessels, thereby facilitating smoother blood flow throughout the body.
Uses and Dosage
Terazosin is administered orally in capsule form. Typically, it is taken once daily at bedtime or twice a day, with or without food. Take terazosin exactly as directed, refraining from altering the dosage or frequency unless specifically advised by your doctor.
The initial dose of terazosin prescribed by your doctor will likely be conservative and then gradually increased. If you happen to discontinue terazosin for several days or longer, promptly inform your doctor. In such cases, your doctor will likely reintroduce the medication at the lowest dose before gradually adjusting it.
While terazosin effectively manages high blood pressure and alleviates symptoms associated with BPH, understand that it does not provide a cure. The full benefits of terazosin for BPH may take approximately 4 to 6 weeks or possibly longer to manifest.
Throughout the treatment period, continue taking terazosin as prescribed, even if you start feeling better. Under no circumstances should you discontinue terazosin without consulting your doctor.
