Who can and cannot take tamsulosin

Most adults aged 18 years and over can take tamsulosin.

This medicine is not usually taken by children under 18 years old, unless a specialist children's doctor prescribes it.

Tamsulosin is not suitable for some people. To make sure this medicine is safe for you, tell a doctor if you:

• have ever had an allergic reaction to tamsulosin or other similar medicines, such as alfuzosin, doxazosin, prazosin or terazosin
• have orthostatic hypotension – a type of low blood pressure that can make you feel dizzy or light-headed when you stand up
• have severe liver or kidney problems
• are having eye surgery for cataracts or glaucoma
• ever faint while peeing or immediately afterwards (micturition syncope)
