What is Catapres?Catapres is used alone or with other medications to lower high blood pressure.
What is the most important information I should know about Catapres?You must take Catapres regularly for it to be effective. Since blood pressure declines gradually, it may be weeks before you get the full benefit of Catapres. You must continue taking it even if you are feeling well. Catapres does not cure high blood pressure; it only keeps it under control.
Do not abruptly stop taking Catapres without consulting your doctor.
If you are using Catapres patch and develop an allergic reaction, rash, vesicles, or severe redness at the treatment site, contact your doctor. You may also develop an allergic reaction or skin rash if you discontinue using the Catapres patch and begin taking Catapres oral tablets. If you experience a mild skin irritation at the treatment site while using Catapres patch before completing the full 7 days of therapy, you may remove the Catapres patch and replace it with a new Catapres patch to a different site on your body.
Used Catapres patches will continue to contain large amounts of drug. It is therefore important for you to keep both used and unused patches away from children and pets and to dispose of used Catapres patches properly.

What should I tell my doctor before I take the first dose of Catapres?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Catapres.

What is the usual dosage?The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval.
Adults: The usual starting dose is 0.1 milligrams (mg) taken 2 times a day in the morning and at bedtime. The regular dose of Catapres is determined by increasing the daily dose by 0.1 mg at weekly intervals until the desired response is achieved. A larger portion of the increased dose can be taken at bedtime to reduce the potential side effects of drowsiness and dry mouth that may appear when you begin taking this drug.

How should I take Catapres?Take Catapres exactly as prescribed, even if you are feeling well. Do not miss any doses. If Catapres is not taken regularly, your condition may get worse.
The Catapres patch should be applied to either the outer part of your arm or to your chest area. The spot where the patch is applied should be hairless and not contain any cuts or bruises. The patch should be worn for 7 days and then taken off and replaced with a new patch. The new patch should not be applied to the same exact spot.
If the patch becomes loose, use the adhesive cover that is included with the Catapres system and place it directly over the Catapres patch to help keep the patch in place.
