Clonidine is also known by the brand name Catapres [1].
Why is clonidine prescribed?
Clonidine is primarily used to treat high blood pressure (hypertension) [1]. It is also prescribed for other conditions, including attention deficit hyperactivity disorder (ADHD), and to manage withdrawal symptoms from certain substances [2].
How does clonidine work?
Clonidine is an alpha-adrenergic agonist. It works by stimulating alpha-2 adrenergic receptors in the brain. This action reduces the release of norepinephrine, a neurotransmitter that constricts blood vessels and increases heart rate. By decreasing norepinephrine, clonidine helps to lower blood pressure and calm the nervous system [3].
What forms of clonidine are available?
Clonidine is available in various formulations, including oral tablets, extended-release tablets, and a transdermal patch [1]. The patch delivers the medication slowly over a period of time.
Can clonidine be used for other conditions?
Beyond hypertension, clonidine has demonstrated efficacy in managing ADHD symptoms, often when other treatments are insufficient [2]. It is also utilized to alleviate withdrawal symptoms associated with opioids, alcohol, and nicotine [4]. Additionally, it may be prescribed for certain types of pain, menopausal hot flashes, and tics [5].
What are the potential side effects of clonidine?
Common side effects of clonidine include drowsiness, dizziness, dry mouth, and constipation [1]. Less common but more serious side effects can occur, and patients should consult their healthcare provider if they experience any concerning symptoms [6].
