Clonidine

Clonidine is used alone or in combination with other medications to treat high blood pressure. Clonidine is in a class of medications called centrally acting alpha-agonist hypotensive agents. It works by decreasing your heart rate and relaxing the blood vessels so that blood can flow more easily through the body.

Clonidine comes as a tablet to take by mouth. It is usually taken two or three times a day at evenly spaced intervals. Take clonidine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take clonidine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Your doctor may start you on a low dose of clonidine and gradually increase your dose, not more than once every week. Clonidine controls high blood pressure but does not cure it. Continue to take clonidine even if you feel well. Do not stop taking clonidine without talking to your doctor. If you suddenly stop taking clonidine, it can cause a rapid rise in your blood pressure and symptoms such as nervousness, headache, and uncontrollable shaking of a part of the body. Your doctor will probably decrease your dose gradually over 2 to 4 days.
