FLOMAXTRA XL is a brand name for the medication known as tamsulosin hydrochloride, which is primarily used in the treatment of benign prostatic hyperplasia (BPH), a condition commonly referred to as an enlarged prostate in men. This medication belongs to a class of drugs known as alpha-blockers, which work by relaxing the muscles in the bladder and prostate, thereby improving urine flow and reducing the symptoms associated with BPH, such as difficulty in starting urination, weak stream, and the need to urinate frequently or urgently. FLOMAXTRA XL is formulated as an extended-release tablet, designed to provide a consistent release of medication over time, allowing for once-daily dosing. It is important for patients to follow their healthcare provider's instructions when taking FLOMAXTRA XL and to be aware of potential side effects, which may include dizziness, headache, and issues related to low blood pressure.
