USES: This medication is used to treat high blood pressure. It works by stimulating certain brain receptors (alpha adrenergic type) which results in the relaxing of blood vessels in other parts of your body, causing them to widen. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.
OTHER USES: This medication may also be used to ease withdrawal symptoms associated with the long-term use of narcotics, alcohol and nicotine (smoking). In addition, clonidine may also be used for migraine headaches, hot flashes associated with menopause, attention deficit hyperactivity disorder, and other conditions as determined by your doctor.
HOW TO USE: Take this medication by mouth, usually twice daily (in the morning and at bedtime) or as directed by your doctor. The dosage is based on your medical condition and response to therapy. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same times each day as directed. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not suddenly stop taking this medication without consulting your doctor because your condition may become worse. A serious rapid increase in your blood pressure (rebound hypertension) may occur when this drug is suddenly stopped or if you miss 2 or more doses in a row, especially if you have been taking it for a long time, at higher doses, or with a beta-blocker medication. Therefore it is important that you do not run out of clonidine. There have been reports of rare, but severe (possibly fatal) results, including stroke, from stopping this drug too quickly. If you must stop taking this drug, your dose should be gradually decreased over several days as directed by your doctor. When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well (e.g., your routine blood pressure readings increase).
