Also known as: Clonidine
Clonidine transdermal is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk for heart attacks. These problems may be less likely to occur if the blood pressure is controlled.
Clonidine belongs to the class of medicines called antihypertensives. It works in the brain to change some of the nerve impulses. As a result, the blood vessels relax and blood passes through them more easily, which lowers blood pressure. When the blood pressure is lowered, the amount of blood and oxygen going to the heart is increased.
This medicine will not cure your high blood pressure, but it does help control it. Therefore, you must continue to use it as directed if you expect to lower your blood pressure and keep it down. You might have to take high blood pressure medicine for the rest of your life.
This medicine is available only with your doctor's prescription.

To use the skin patch:
Use this medicine exactly as directed by your doctor. It will work only if applied correctly. This medicine usually comes with patient instructions. Read them carefully before applying the patch. Wash your hands with soap and water before and after applying a patch. Do not touch your eyes until after you have washed your hands. Do not try to trim or cut the adhesive patch to adjust the dosage. Check with your doctor if you think the medicine is not working as it should. Gently wash the area of skin where you will apply the patch with soap and water. Rinse the skin completely and dry with a clean, dry tissue. Apply the patch right away after removing it from the pouch. Do not cut it into smaller pieces and do not touch the sticky surface of the patch. Apply the patch to a clean, dry, and intact skin area on your upper, outer arm or upper chest. Choose an area with little or no hair that is free of scars, cuts, or irritation. Avoid putting the patch on skin areas where it could be rubbed off by tight clothing. Press the patch firmly in place with your fingertips to make sure that the edges stick well. The patch should stay in place during showering, bathing, or swimming for a full 7 days. If the patch becomes loose, press the edges against the skin and cover the patch with one of the white adhesive covers that are included in the package. Apply a new patch if the first one becomes too loose or falls off. It is best to apply each patch to a different area of the skin to prevent skin irritation.
To help you remember to use your medicine, try to apply the patch at the same time and on the same day of the week.
