Clonidine Transdermal Patch
(kloe' ni deen)
WHY is this medicine prescribed?
Transdermal 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.
HOW should this medicine be used?
Transdermal clonidine comes as a patch to apply to the skin. It is usually applied to the skin every 7 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use the clonidine patch exactly as directed. Do not apply it more or less often than prescribed by your doctor.
Apply clonidine patches to clean, dry skin on a hairless area on the upper, outer arm or upper chest. Choose an area where it will not be rubbed by tight clothing. Do not apply patches to skin that has wrinkles or folds or to skin that is cut, scraped, irritated, scarred or recently shaved. You may bathe, swim, or shower while you are wearing a clonidine patch.
If the clonidine patch loosens while wearing it, apply the adhesive cover that comes with the patch. The adhesive cover will help to keep the clonidine patch on until it is time for the patch to be replaced. If the clonidine patch significantly loosens or falls off, replace it with a new one in a different area. Replace the new patch on your next scheduled patch change day.
Your doctor may start you on a low dose of clonidine patch and gradually increase your dose, not more than once every week.
Clonidine patch controls high blood pressure but does not cure it. It may take 2-3 days before the full benefit of clonidine patch is seen in your blood pressure readings. Continue to use clonidine patch even if you feel well. Do not stop using clonidine patch without talking to your doctor. If you suddenly stop using clonidine patch, it can cause a rapid rise in blood pressure and symptoms such as nervousness, headache, and confusion. Your doctor will probably decrease your dose gradually over 2 to 4 days.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient and read it carefully. To apply the patch, follow the directions in the patient instructions. Be sure to ask your pharmacist or doctor if you have any questions about how to use this medication.
Are there OTHER USES for this medicine?
Clonidine patch is also sometimes used as an aid in smoking cessation therapy and for the treatment of menopausal hot flashes. Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
