Just a few questions from our Pharmacist before you checkout to make sure this medicine is safe for you.
What are Circadin 2mg Prolonged Release tablets?
Circadin 2mg Prolonged Release tablets are a sleep aid designed to treat short-term insomnia, especially in the over 55s. Circadin tablets use an active ingredient that’s naturally produced in your body when you fall asleep, helping to make you feel drowsy so you can drop off for a restful night’s sleep. If you’re struggling to get the sleep you need at night and find that regular over the counter remedies aren’t right for you, Circadin could be the perfect solution.
How to take these tablets
Take one Circadin 2mg tablet a day 1 - 2 hours before your bedtime. Take after food with a sip of water. You can take this product for up to 13 weeks, if your symptoms have not improved after this time, speak to your doctor.
How will the melatonin 2mg in Circadin tablets help me to sleep?
The active ingredient in Circadin tablets is 2mg of melatonin. Melatonin is a natural hormone that is produced in your body when it gets dark outside and your body prepares to go to sleep. Melatonin makes you feel drowsy and if your body does not produce enough melatonin then you can find it difficult to fall asleep and stay asleep. By providing a prolonged-release source of melatonin these tablets can help you to fall asleep at night.
What is insomnia?
When you have insomnia it means that you struggle to fall asleep or stay asleep at night. You may wake up several times in the night and find yourself lying awake staring at the ceiling wondering why you can’t just get some sleep. When you’re suffering from insomnia it can make you feel tired and irritated, and you may find it more difficult to concentrate on your work or other things you may be doing during the day.
