1. What is Circadin and what is it used for
The active substance of Circadin is melatonin and it belongs to a group of natural hormones produced by the body.
Circadin is used on its own for the short-term treatment of primary insomnia (persistent difficulty in falling asleep or staying asleep or poor quality sleep) in patients over 55 years of age. "Primary" means that the insomnia does not have any known cause, whether medical, mental or environmental.
2. What you need to know before you take Circadin
Do not take Circadin
- if you are allergic to melatonin or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Consult your doctor or pharmacist before taking Circadin.
- If you have liver or kidney problems. No studies have been conducted on the use of Circadin in people with liver or kidney disease; you should talk to your doctor before taking Circadin, as its use is not recommended.
- If your doctor has told you that you have an intolerance to some sugars.
- If you have been told that you have an autoimmune disease (when the body is "attacked" by its own immune system). No studies have been conducted on the use of Circadin in people with autoimmune diseases; therefore, you should talk to your doctor before taking Circadin, as its use is not recommended.
- Circadin may cause drowsiness; you should be careful if you experience drowsiness, as it may affect your ability to perform tasks such as driving.
- Tobacco may reduce the effectiveness of Circadin, as the components of tobacco smoke may increase the breakdown of melatonin in the liver.
