Circadin Tablets
Circadin is a branded version of modified-release melatonin. Melatonin plays a role in your natural sleep-wake cycle. Natural levels of melatonin in the blood are highest at night.
Some research suggests that melatonin supplements might help treat sleep disorders, such as delayed sleep phase, and provide some relief from insomnia and jet lag.
Melatonin is generally safe for short-term use. Unlike with many sleep medications, with melatonin, you are unlikely to become dependent, have a diminished response after repeated use (habituation), or experience a hangover effect.
It comes in a 2mg tablet and is a prescription-only medication. You must speak to one of our prescribers to ensure Melatonin is prescribed for your needs.
Circadin is a medicine that is used to treat jetlag and to adjust an irregular sleep pattern. It contains the active ingredient melatonin, which is also found naturally in the body. It works by increasing the levels of melatonin in the body at night, which aids sleep. The body produces more melatonin at night, which produces a regular night cycle. Light prevents the production of melatonin, which means we are more alert during the day.
