• Catapres-TTS-1 is applied to the skin once every 7 days. On Day 8, a new patch is applied, and the old patch should be removed. Apply the patch to a hairless area of intact skin (no burns, bruises, or cuts) on the upper outer arm or chest. Each new patch should be applied on a skin site different from the site of the old patch. If the patch loosens during 7-day wearing, the adhesive cover should be applied directly over the patch to ensure good adhesion.
• Discuss with your doctor about what to do if redness or swelling occurs at patch site.

Use Catapres-TTS-1 exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

To start therapy, the patch dosage should be adjusted according to individual needs, starting with the lowest patch dose (0.1 mg). If after one or two weeks the desired decrease in blood pressure is not achieved, your dose may be increased by your doctor by adding another Catapres-TTS-1 (clonidine) 0.1 mg patch or changing to a larger system (0.2 or 0.3 mg).

If you applied more Catapres-TTS-1 than directed, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

During or even after use, patch contains active medication which may be harmful to infants and children if accidentally applied or ingested. After use, fold in half with the sticky sides together. Dispose of carefully out of reach of children.
