Ceyesto 1mg Oral Solution contains melatonin in a liquid form, measured with the device supplied so the dose can be given precisely. It is used for sleep problems where a clinician has assessed that melatonin is appropriate, and a liquid suits anyone who finds tablets difficult to swallow.
Melatonin is a hormone produced naturally by the pineal gland as light fades, and it is the signal that tells the body the night has begun. Taking it supplements that signal and helps shift the timing of the sleep and wake cycle. It works on timing rather than acting as a sedative, which is why when it is taken matters as much as how much is taken.
Measure the dose with the syringe or spoon supplied and take it at the time your clinician has specified, usually a set period before bed. Keep the timing consistent, dim lights and screens in the hour beforehand, and keep wake up times steady, since melatonin works alongside those habits rather than replacing them.
It is for people where a clinician has assessed melatonin as suitable and confirmed the dose and duration. It is not suitable for anyone with a known sensitivity to the ingredients, and a clinician needs to know about liver or kidney problems, autoimmune conditions, epilepsy and all other medicines you take.
Drowsiness, headache and daytime grogginess can occur, so do not drive or operate machinery until you know how it affects you, and avoid alcohol. Contact your clinician if sleep is no better after the agreed trial period, if daytime sleepiness is a problem, or before stopping or changing the dose. Our UK pharmacy team can answer questions about this product before you buy.
Does timing matter?
Yes. Melatonin shifts the body clock, so taking it at the time agreed with your clinician is important.
Is it habit forming?
It is not considered habit forming in the way sedatives are, but it should still be used for the period agreed and reviewed.
Why a liquid rather than tablets?
A solution allows precise small doses and suits anyone who struggles to swallow tablets.
Always read the patient information leaflet supplied with the pack before use.
