What is Circadin?
Circadin contains melatonin. Melatonin is a natural hormone that our body releases after the onset of darkness. It makes people feel sleepy and it helps to regulate the body’s circadian rhythm. Circadin is licensed to be used on its own for short-term use in people aged 55 and over, who find it difficult to get to, or to stay, asleep. It should not be used in people who cannot sleep due to a medical, mental or environmental cause. It is also used off-licence in the treatment of jet-lag. It has been found to be particularly effective in those who are travelling eastwards.
