What is Catapres and How to Take It

Clonidine belongs to the class of central alpha agonists. It is available in tablet and transdermal patch forms. Catapres is a common brand of clonidine. Extended-release tablets are also available under the brand name Kapvay. Clonidine is available in various strengths, including 0.1 mg, 0.2 mg, and 0.3 mg tablets. These different dosage options allow for flexibility in prescribing the appropriate amount for individual patients based on their medical needs and response to the medication. The brand Duraclon offers an intravenous (IV) form of clonidine specifically intended to alleviate severe pain in cancer patients. Within the same therapeutic class, other drugs include methyldopa, guanfacine, and moxonidine.

Clonidine works by binding to alpha-2 adrenergic receptors in the central nervous system, leading to reduced sympathetic activity, vasodilation, and decreased heart rate, resulting in lowered blood pressure. Its interaction with alpha-2 receptors in the spinal cord helps inhibit pain signal transmission, making it effective for managing severe pain, particularly in cancer patients.

Clonidine is available in tablet form, as well as a transdermal patch and extended-release tablets. For adults, the typical starting dose of clonidine is a 0.1 mg tablet taken twice daily, once in the morning and once at bedtime. You can take Clonidine tablets with or without food, and make sure to drink a full glass of water with them.

The transdermal patch is applied once every seven days. Apply the patch on dry skin that is clear and not hairy.
