Tamsulosin is not indicated for use in women. It is primarily prescribed for the treatment of BPH in men.

Get medical help right away if you have any serious side effects such as an allergic reaction. Symptoms include hives, trouble breathing, shortness of breath, sore throat, chest pain, swelling of the face, tongue or throat, skin rash, and severe skin reactions. Promptly report any adverse effects to a healthcare professional for medical advice.
