TAMISO MR CAPS (Tamsulosin) is an alpha-blocker that relaxes the muscles in the prostate and bladder neck, making it easier to urinate. Tamsulosin is used to improve urination in men with benign prostatic hyperplasia (enlarged prostate). Tamsulosin is not FDA approved for use in women or children.
It does not shrink the prostate, but it works by relaxing the muscles in the prostate and the bladder. This helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate often or urgently (including during the middle of the night).
Tamsulosin oral capsule is available as the brand-name drug Flomax.
