Minipress belongs to a class of medications called alpha blockers. It works by relaxing and widening blood vessels so blood can flow more easily. This medication is used with or without other medications to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

Take it at the same time each day. Take each dose with a full glass of water. Initial dose is 1 mg two or three times a day. Your dosage may be slowly increased to maximum dose of 20 mg given in divided doses.
