Tamsulosin (OTC)

Quick reference guide 

Tamsulosin is indicated for the treatment of functional symptoms (i.e. urinary retention) of benign prostatic hyperplasia (prostate enlargement); commonly referred to as BPH. Tamsulosin is an alpha1-adrenoceptor antagonist (alpha-blocker) that relaxes the muscles in the prostate gland and urethra thereby increasing the urinary flow-rate and an improvement in obstructive symptoms. Tamsulosin hydrochloride 400 microgram capsules can be supplied as a pharmacy (P) medicine.

See the NICE guidance, Lower urinary tract symptoms in men; management (CG97), for information on lower urinary tract symptoms in men. Lifestyle advice and 'watchful waiting' are the first options to consider.
