Clonidine Transdermal Patch Dosage
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 transdermal 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 transdermal 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 transdermal 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.
Keep all appointments with your doctor. Your blood pressure should be checked regularly to determine your response to the clonidine transdermal patch.
Your doctor may ask you to check your pulse (heart rate) daily and will tell you how rapid it should be. Ask your doctor or pharmacist to teach you how to take your pulse. If your pulse is slower or faster than it should be, call your doctor.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
