Tamsulosin (Tamsulosin hydrochloride) — Uses, Dosage, Side Effects & Safety

Drug class: Alpha-1 adrenergic antagonist (Alpha blocker)

Overview

Tamsulosin is a medication used to treat the symptoms of benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland in men. It helps relieve symptoms such as difficulty starting urination, weak stream, and the need to urinate frequently or urgently. Tamsulosin works by relaxing the muscles in the prostate and the bladder neck, making it easier to urinate. It does not shrink the prostate but improves urine flow and reduces symptoms. Key points for patients: Tamsulosin is usually taken once daily, about 30 minutes after the same meal each day. It may cause dizziness, especially when standing up quickly. It is important to continue taking the medication as prescribed, even if you feel well.
