Buy Circadin (Melatonin) Prolonged-release Tablets

Circadin tablets are a sleep aid designed to treat short-term insomnia, especially in people over the age of 55. 

If you’re struggling to get the sleep you need at night and find that regular over-the-counter (OTC) remedies aren’t working, this product could be the perfect solution.

 

How Circadin (Melatonin) Prolonged-release Tablets work

Circadin contains melatonin, a natural hormone produced in your body when it gets dark outside, and your body prepares to sleep. 

Melatonin makes you feel drowsy, and if your body doesn’t produce enough melatonin, you might find it difficult to fall asleep or stay asleep.

The prolonged-release source of melatonin in these tablets can help you fall asleep at night.

 

Directions

Always take Circadin exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

Swallow each tablet whole with water. Do not crush or cut them in half. 

You should take 1 tablet after food, approximately 1-2 hours before bedtime. 

You can take these tablets for up to 13 weeks.

 

Side effects

Like all medicines, Circadin may cause side effects in some people, but these won’t affect everybody. There are no known reported common side effects of this medicine. 

If you experience any side effects, including any not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme.

 

Serious side effects

Seek emergency medical attention if you notice any signs of a severe allergic reaction, symptoms of which include swelling of the face and throat, skin rash, breathing difficulties and/or loss of consciousness. 

If you experience any of the following serious side effects, stop taking this medication immediately and seek medical advice straight away:

 

  • Chest pain 
  • Severe chest pain caused by angina 
  • Loss of consciousness/fainting 
  • Depression 
  • Visual impairments or changes
  • Blurred vision 
  • Feeling disorientated 
  • Vertigo 
  • Red blood cells in your urine
  • A reduced number of white blood cells in the blood 
  • Reduced blood platelets, which can increase your chances of bruising or bleeding 
  • Psoriasis 

 

Warnings

Circadin may be unsuitable for certain people. Do not take these tablets if you are allergic to any of the ingredients.

Talk to your doctor or Chemist4U pharmacist before taking this medicine if: 

 

  • You suffer from liver or kidney problems 
  • You have an intolerance to some sugars 
  • You have an autoimmune disease 
  • You are a smoker

Pregnancy and breastfeeding

Do not take this medicine if you are pregnant.  If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, you must ask your doctor or Chemist4U pharmacist for advice before taking any new medicine. 

 

Alcohol
