Clonidine, sold as the brand name Catapres among others, is a medication used to treat high blood pressure, attention deficit hyperactivity disorder, drug withdrawal (alcohol, opioids, or smoking), menopausal flushing, diarrhea, and certain pain conditions. Clonidine is used to treat high blood pressure, attention deficit hyperactivity disorder (ADHD), drug withdrawal (alcohol, opioids, or smoking), menopausal flushing, diarrhea, and certain pain conditions. It can alleviate opioid withdrawal symptoms by reducing the sympathetic nervous system response such as tachycardia and hypertension, as well as reducing sweating, hot and cold flashes, and general restlessness. Clonidine also has several off-label uses, and has been prescribed to treat psychiatric disorders including stress, sleep disorders, and hyperarousal caused by post-traumatic stress disorder, borderline personality disorder, and other anxiety disorders. Clonidine has also been used to treat refractory diarrhea associated with irritable bowel syndrome, fecal incontinence, diabetes, withdrawal-associated diarrhea, intestinal failure, neuroendocrine tumors and cholera. The reduction in circulating norepinephrine by clonidine was used in the past as an investigatory test for phaeochromocytoma, which is a catecholamine-synthesizing tumour, usually found in the adrenal medulla. In a clonidine suppression test plasma catecholamine levels are measured before and 3 hours after a 0.3 mg oral test dose has been given to the patient. It’s available as a patch, an oral tablet, and an oral extended-release tablet. Clonidine extended-release tablets are available as the brand-name drug Kapvay. Clonidine extended-release tablets are used to treat symptoms of attention deficit hyperactivity disorder (ADHD). This drug may be used as part of a combination therapy. In some cases, they may not be available in every strength or form as the brand. That means you may need to take it with other drugs. Clonidine belongs to a class of drugs called centrally acting alpha-agonists. It isn’t known exactly how clonidine extended-release tablets work to reduce symptoms of ADHD. We do know that clonidine works in the part of the brain that helps regulate behavior, attention, and how we express emotion. However, this effect might go away the longer you take it. Mild side effects may go away within a few days or a couple of weeks. Talk to your doctor or pharmacist if they’re more severe or don’t go away.
This medication is used alone or with other medications to treat attention deficit hyperactivity disorder (ADHD) as part of a total treatment plan, including psychological, social, and other treatments. Read the Patient Information Leaflet if available from your pharmacist before you start taking clonidine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food as directed by your doctor, usually twice daily (in the morning and at bedtime). If the doses are not equal, take the larger dose at bedtime. Doing so can release all of the drug at once, increasing the risk of side effects. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing. Clonidine lowers blood pressure by decreasing the levels of certain chemicals in your blood. This allows your blood vessels to relax and your heart to beat more slowly and easily. The Catapres brand of clonidine is used to treat hypertension (high blood pressure). The Kapvay brand is used to treat attention deficit hyperactivity disorder (ADHD). Clonidine is sometimes given with other medications. Before you take clonidine, tell your doctor if you have heart disease or severe coronary artery disease, a heart rhythm disorder, slow heartbeats, low blood pressure, a history of heart attack or stroke, kidney disease, or if you have ever had an allergic reaction to a Catapres TTS transdermal skin patch. You should not take this medicine if you are allergic to clonidine.
