Clonidine<\/span><\/a> is a generic prescription medication that helps calm the nervous system, relax blood vessels, and slow the heart rate. Brand names include Catapres, Javadin, and Kapvay. While it\u2019s FDA approved to treat high blood pressure, medical providers may also prescribe it off-label for ADHD, anxiety, tics caused by Tourette\u2019s syndrome, menopausal symptoms, and sleep disorders. The medication\u2019s relaxing effects can be helpful for certain health conditions, but they can also cause drowsiness for several hours after your dose and even into the next morning\u2014disrupting daily activities like work, driving, and everyday responsibilities.<\/span><\/p>\n

How does clonidine induce sleepiness?<\/span><\/h2>\n

Clonidine works to induce sleepiness by blocking the release of norepinephrine, a chemical that helps keep the body alert, says <\/span>Jordan Spencer<\/span><\/a>, DO, a psychiatrist at Barrier Islands Psychiatry in Charleston, South Carolina. \u201cIt lowers your \u2018fight or flight\u2019 response to induce a calming effect.\u201d<\/span><\/p>\n

Think of clonidine as a \u201cvolume knob\u201d for the nervous system, says <\/span>Linda Khoshaba<\/span><\/a>, NMD, founder of Natural Endocrinology Specialists in Scottsdale, Ariz. \u201cWhen that chemical level drops, your heart rate slows down, and your brain gets a very loud message that it\u2019s time to take a nap,\u201d Khoshaba explains. \u201cIt\u2019s basically like flipping a switch from go mode to rest mode.\u201d<\/span><\/p>\n\t\t

How long does clonidine make you sleepy?<\/span><\/h2>\n

Many people will notice sleepiness within about 30 or 60 minutes after taking an immediate-release dose, with the strongest effect within one to four hours, says <\/span>Austin Traasdahl<\/span><\/a>, DO, a family medicine provider with Alexander Medicine in the Phoenix, Arizona, suburbs. How long sleepiness lasts varies, however, depending on the dose of clonidine and the patient. \u201cSome feel it for a few hours, while others can feel drowsy into the next morning,\u201d Trassdahl says.<\/span><\/p>\n

The half-life\u2014or the time it takes for half of the medication to leave a person\u2019s bloodstream\u2014is between 12 and 16 hours. \u201cBecause it stays in your system for a while, you might still feel a little bit of a hangover or lingering grogginess even the next morning,\u201d Khoshaba says.<\/span><\/p>\n

Yet everyone\u2019s body metabolizes drugs differently. \u201cIf your system runs a bit slower, or if your genetics make you more sensitive to nervous system changes, that sleepy feeling is going to stick around much longer than it might for someone else,\u201d Dr. Khoshaba said.\u00a0<\/span><\/p>\n

Factors that influence clonidine\u2019s sedative effects<\/span><\/h2>\n

Several variables affect how quickly the sleepy feeling passes after taking clonidine tablets.<\/span><\/p>\n
