What to know about Tamsulosin

How it Works

Tamsulosin is prescribed in 0.4mg capsules and is usually taken daily 30 minutes after a meal. Tamsulosin helps reduce the symptoms of an enlarged prostate by relaxing the muscles in the prostate and bladder allowing urine to flow more freely.

Who is it for?

Alpha blocker medications like Tamsulosin are used to treat the negative symptoms men may experience from an enlarged prostate (BPH). These can include difficulty urinating, painful urination, and urinary frequency.


One study of Tamsulosin’s effects on BPH symptoms reported a more than a 30% improvement in peak urinary flow rate. For urinary incontinence associated with BPH, most men see results from 0.4mg but in more severe cases, it may require a 0.8mg dose to see effects.1
