What Drug Clonidine?

What is Clonidine for?

Clonidine is a drug to lower high blood pressure, helps prevent strokes, heart attacks, and kidney problems. This medicine can be used alone or in combination with other drugs.

Clonidine belongs to the class A drug (central alpha agonist) that acts on the brain to lower blood pressure. This medicine lowers the pressure of the blood vessels so that blood can flow more easily. This medication may also be used for attention deficit hyperactivity disorder (ADHD), coping withhot flushes that occurs at menopause, symptoms resulting from narcotics use, and helps people to quit smoking.

Clonidine dosage and clonidine side effects are described in more detail below.

How to use Clonidine?

Read the Patient Information leaflet if available from your pharmacist before starting clonidine and each time you get a refill. If you have questions, ask your doctor or pharmacist.

Unpack and apply the patch to a clean, dry area and a lint-free upper arm skin or upper chest. Press the patch for about 10 seconds to make sure it stays in place. Do not place the patch on oily, injured, or irritated skin. Avoid applying the patch to areas of skin where it may fall off easily (such as in skin folds). Use this medication as directed by your doctor. The patch is usually worn for 1 week and then replaced. Follow the dosing schedule carefully. Wash hands after touching patch.

Dosage is based on your medical condition and your body's response to treatment.

When changing your patch, make sure to apply the new patch to a different area. Fold the old patch in half with the sticky sides sticking together and throw it in the trash that is out of reach of children and pets. Don't throw the patch down the toilet.

If the patch starts to loosen up from the skin, you can apply adhesive over the patch so that it doesn't come off for about 1 week. This adhesive does not contain any medicine. If the patch falls off or if you have mild redness / itching / irritation around the area where the patch was applied, remove the patch as directed and apply the new patch to a different area.

Use this remedy regularly to get maximum results. As a reminder, change the patch on the same day every week. Mark calendars as reminders. It is important to continue using this medication even if you feel better. Most people with high blood pressure feel no pain.

Do not stop using this medication without an order from your doctor. You may experience symptoms such as restlessness, agitation, trembling, and headaches. Rapidly rising blood pressure can also occur if the use of this drug is suddenly stopped. The risk is greater if you use this drug for a long time or in high doses, or if you also take beta blockers (such as atenolol). There are also rare reports of possible serious fatal reactions (such as stroke) to stopping using this drug too quickly. Therefore, it is important that you do not run out of clonidine patches or miss doses. To prevent any reactions when you stop treatment with this medicine, your doctor may reduce the dose gradually. Consult your doctor or pharmacist for more details. Report new symptoms or if they get worse.

When used for a long time, this drug may not work well and may require a different dose or additional medication. Talk to your doctor if the function of this drug has decreased (for example, your blood pressure remains high or tends to increase).
