Hetlioz is a prescription medication used to treat a serious, chronic circadian rhythm disorder known as non-24-hour sleep-wake disorder (Non-24). Non-24 affects up to 70% of people who are totally blind. Hetlioz belongs to a group of drugs called melatonin MT1 and MT2 receptor agonists. These work by mimicking the natural substances that are involved with sleep-wake cycles (circadian rhythms).

This medication comes as a capsule. It is taken once a day at night without food.

Common side effects include headache, nightmares, or unusual dreams. Hetlioz can also cause drowsiness. Do not drive or operate heavy machinery until you know how this medication affects you.

This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans.
