Tamsulosin (flomax) is a medication primarily used to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH). It is known by several brand names, including Flomax, Alna, and Contiflo. Tamsulosin works by relaxing the muscles in the prostate and bladder neck, making it easier for men with BPH to urinate. While it can be an effective treatment, it is essential to be aware of potential side effects.

Common Side Effects:
Tamsulosin is generally well-tolerated, but like any medication, it can cause side effects. The most common side effects associated with tamsulosin include:

Orthostatic Hypotension: Approximately 7% of patients receiving tamsulosin may develop orthostatic hypotension after the first dose, typically occurring approximately four hours after taking the medication. This condition involves a sudden drop in blood pressure when transitioning from sitting or lying down to standing.
