Trade Name(s) : Minipress XL GITS, Prazopress
Why it is prescribed: Prazosin controls high blood pressure by relaxing the blood vessels so that blood can flow more easily through the body. It also has been used, with other medication, to treat heart failure.
When it is to be taken: Prazosin is usually taken three times a day at evenly spaced intervals e.g., when you wake up, in the afternoon, and at bedtime. Follow the instructions on your prescription label carefully, and ask your doctor to explain any part that you do not understand. This medication controls but does not cure high blood pressure and heart failure. Therefore, it is important that you take this medication regularly. You may have to take prazosin for four to six weeks before feeling its full effects.
How it should be taken: Prazosin comes in form of capsules. Your prescription label tells you how much to take at each dose.

1. Prazosin can cause dizziness, lightheadedness, and fainting, especially after the first dose. Lie down for at least one hour and get up slowly after the first dose.
