Melatonin tablets for insomnia

About melatonin

Poor sleep can mean that you have difficulty getting to sleep, or that you wake up for long periods during the night, or that you wake early, or that you do not feel refreshed in the mornings.

Insomnia is a fairly common condition, but it does not usually last for long. Melatonin is a hormone which occurs naturally in the body and is associated with the control of the body's sleep pattern. As we grow older the amount of naturally occurring melatonin in the body reduces. Taking melatonin adds to the body's natural supply and helps to promote and improve the quality of sleep.

Circadin® and Civasta® tablets are prescribed for people over the age of 55 years who have insomnia, or difficulty sleeping.

Slenyto® tablets are prescribed for poor sleep in children between the ages of 2 years and 18 years with Autism Spectrum Disorder (ASD) or Smith-Magenis syndrome.

Adaflex® and Ceyesto® tablets are prescribed for poor sleep in children aged 6 to 17 years with ADHD. They can also be prescribed for adults who experience jet lag.

Syncrodin® tablets are prescribed for adults who experience jet lag.

Sometimes a doctor may prescribe melatonin for other groups of people with sleeping problems. If this is the case for you, the way you take melatonin and your dose may be different from the information in this leaflet. Follow your doctor's instructions carefully and ask your doctor or pharmacist if you are unsure of anything.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking melatonin it is important that your doctor or pharmacist knows:

• Se você tiver algum problema com o funcionamento do seu fígado ou com o funcionamento dos seus rins.

• If you have an autoimmune disease - a condition in which the body is attacked by its own overactive immune system. It includes conditions such as artrite reumatoide, multiple sclerosis, and lupus.

• Se você estiver tomando outros medicamentos. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

• Se você já teve uma reação alérgica a um medicamento.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about melatonin and will provide you with a full list of the side-effects which you may experience from taking it.

• Take melatonin exactly as your doctor tells you to. For adults the dose is usually one 2 mg tablet daily, taken 1-2 hours before bedtime. For children with ASD the usual starting dose is 2 mg taken 30 minutes to one hour before bedtime. Your child's doctor may increase the dose slowly to get a better response.

• Take the tablet with a snack or after eating some food. This will help the medicine to work later into the night. Swallow the tablet whole - do not break or crush the tablet because it is designed to release melatonin slowly over a few hours.

• If you forget to take a tablet at the usual time but you remember before you go to sleep, take it when you remember. If you do not remember until the following day, just take the next dose as usual. Do not take two doses together to make up for a forgotten dose.

• Do not take melatonin for longer than your doctor advises. It can be prescribed for up to 13 weeks for adults over 55.

• Do not drink alcohol while you are taking melatonin because it will reduce the medicine's effectiveness in helping you to sleep.

• Try to keep your regular appointments with your doctor. This is so your progress can be monitored.

• There are some general recommendations that may help promote good sleep. Try to reduce the amount of caffeine you drink, especially in the afternoon and evening. Try to avoid eating heavy meals or drinking alcohol before bedtime. Exercise early in the day, rather than in the evening.

Along with their useful effects, most medicines can cause unwanted side-effects but not everyone experiences them. The table below contains some of the side-effects associated with melatonin. Children may be more likely than adults to experience these side-effects. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to the tablets, speak with your doctor or pharmacist for further advice. Children with ASD may be more likely to experience mood swings, irritability or aggression when taking melatonin.

• Mantenha todos os medicamentos fora do alcance e da vista das crianças.

• Armazene em local fresco e seco, longe de calor e luz diretos.
