Patient leaflet - Morvesin 400 microgram SSR capsules

1 What Morvesin is and what it is used for

The active substance of Morvesin is tamsulosin. This is an alpha-1-receptor blocker that reduces the ability to contract the muscles in the prostate and urethra. As a result, the urethra, which runs through the prostate, is less constricted so that urinating is easier. In addition, it diminishes sensations of urge.

Morvesin is used by men for the treatment of complaints in the lower urinary tract that occur in benign prostate enlargement. These complaints may include difficulty urinating (poor stream), dribbling, urgency and having to urinate frequently at night as well as during the day.
