PROSTACIN 0.4 MG contains Tamsulosin, an alpha-blocker medication used to treat symptoms of benign prostatic hyperplasia (BPH), a condition where the prostate gland enlarges, causing urinary difficulties. Tamsulosin works by relaxing the muscles in the prostate and the bladder neck, which helps improve urine flow and reduces symptoms like frequent urination, urgency, and difficulty starting urination. At a dose of 0.4 milligrams (MG), PROSTACIN is commonly prescribed to help manage these symptoms and improve quality of life for men with BPH. It is typically taken once daily, usually after a meal. As with any medication, it’s important to follow the prescribed dosage and consult with a healthcare provider regarding potential side effects or interactions with other medications.
