Circadin is a medicine made by Lundbeck, and is indicated for primary insomnia in people aged 55 and over. It relieves symptoms by providing the body with more of the hormone which it requires to help it sleep. Please note that it is not suitable for persons under this age, or who are suffering from secondary insomnia.

The list of reasons why someone might find it difficult to sleep are long. Everyone experiences trouble getting to sleep sometimes, but those cases which are persistent are referred to as insomnia. Sometimes, a person might not be able to sleep because they are going through a period of stress, living with an undiagnosed illness, or maintaining an unhealthy lifestyle.

Insomnia caused by these factors (or secondary insomnia) is usually treated by addressing the source of the problem, for instance: making alterations to an unhealthy diet; visiting the doctor to get treatment for conditions which might be inhibiting sleep, such as arthritis or urinary incontinence; or taking measures to reduce feelings of anxiety.

However, primary insomnia is different. This is defined as the inability to sleep when there is a lack of any other psychological, medical, environmental or dietary cause. It occurs more often in older people, and is due to the slowed production of a hormone which the body needs to help it sleep.

Melatonin is the name of this hormone, which is released by the pineal gland. Levels of the hormone rise after dark at nighttime, and most typically begin to decrease around 4am. It is melatonin which is responsible for letting the brain know that it is time to sleep, and for the body to begin shutting down for the day.

In older people, the ability to produce this hormone can become weakened, making it harder for people to sleep or get a sufficient amount required for normal function.

Circadin contains an artificial version of this hormone, and works by increasing the presence of melatonin in the body. This aids a peaceful night’s rest and can reduce the time it takes for the user to get to sleep.
