Why is this medication prescribed?

To treat high blood pressure, transdermal clonidine may be used alone or in conjunction with other drugs. The drug clonidine belongs to the group of drugs known as centrally acting alpha-agonist hypotensive agents. It functions by lowering heart rate and relaxing blood vessels to allow for easier blood circulation throughout the body.

How should this medicine be used?

Clonidine transdermally is available as a patch to apply to the skin. Every seven days, it is often administered to the skin. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the clonidine patch instructions precisely. Use it only as directed by your doctor, neither more nor less frequently.

Apply clonidine patches on a hairless area of the upper chest, outer arm, or clean, dry skin. Choose a location where clothing that is too tight won’t rub against it. Applying patches to skin with creases or wrinkles, as well as skin that has recently been cut, scraped, irritated, scarred, or shaven, is not advised. Using a clonidine patch doesn’t prevent you from taking a shower, a bath, or a swim.

Use the sticky cover that comes with the patch if the clonidine patch becomes loosened while being worn. Until it is time to replace the patch, the sticky cover will assist keep the clonidine patch in place. Replace the clonidine patch with a new one in a different location if it becomes noticeably loose or slips off. On your subsequent planned day for patch changes, replace the new patch.

A modest dose of clonidine patch may be prescribed by your doctor, who will then gradually increase it up to once per week.

Although it does not treat high blood pressure, the clonidine patch manages it. Before the full effects of the clonidine patch are noticeable in your blood pressure readings, it may take two to three days. Even if you feel good, continue to apply the clonidine patch. Without consulting your doctor, never stop using the clonidine patch. The abrupt discontinuation of clonidine patch use might result in a sharp increase in blood pressure as well as symptoms including anxiety, headaches, and confusion. Your dose will likely be reduced gradually over the course of two to four days by your doctor.

Get a copy of the manufacturer’s information for the patient from your pharmacist or doctor and carefully study it. Follow the instructions in the patient instructions to apply the patch. If you have any concerns about how to use this medication, be sure to consult your doctor or pharmacist.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom). By opening the bag and folding each patch in half with the sticky sides together, you can dispose of any patches that are outdated or no longer required. Make sure to carefully dispose of the folded patch and keep it out of the reach of children and animals.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at for additional information.

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Remove any additional clonidine patches that have been applied to the skin. Then dial 1-800-222-1222 to reach your neighbourhood poison control centre. Dial 911 to reach the nearest emergency services if the sufferer has collapsed or has stopped breathing.

  • Shivering
  • Muddled speech
  • Tiredness
  • Confusion
  • Pale, icy skin

What other information should I know?

Keep all of your doctor’s appointments. To assess how well the clonidine patch is working for you, have your blood pressure monitored frequently.

Your doctor may instruct you to check your pulse (heart rate) each day and will specify the ideal rate. To learn how to take your pulse, ask your doctor or pharmacist. Call your doctor if your pulse is slower or faster than it should be.

Do not share your medication with anybody else. Any queries you may well have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
