Quick summary: Slenyto is a melatonin-based prescription medicine used for sleep problems in certain children and adolescents, especially those with autism spectrum disorder (ASD). It is a controlled-release formulation, so the way it is taken matters.

What is Slenyto?
Slenyto is a melatonin-based prescription medicine. Melatonin is a hormone involved in the body’s sleep-wake cycle. Slenyto is designed as a controlled-release product, which means it releases melatonin gradually over time rather than all at once.
The original content describes Slenyto as being available in 1 mg and 5 mg strengths.
How Slenyto works
Slenyto is intended to help improve sleep quality and reduce the time it takes to fall asleep. It is not described as a sedative in the source content. Instead, it is used to support a more regular sleep pattern by providing melatonin in a controlled way through the night.
This can be relevant for children whose sleep cycles are disrupted, including some children with ASD.
Who may be prescribed Slenyto?
The original content says Slenyto is primarily prescribed for children and adolescents aged 2 to 18 years with insomnia related to autism spectrum disorder (ASD).
It also mentions use in children with Smith-Magenis syndrome, where sleep disturbance can be common.
In practice, a clinician will usually consider whether sleep hygiene measures and other non-medicine approaches have already been tried before prescribing a medicine like Slenyto.
Dosage information in the original content
The source text states that an initial dose of 2 mg is typically given about 30 to 60 minutes before bedtime, with adjustment by a healthcare professional if needed, up to a maximum of 10 mg.
Because dosing can depend on the child’s age, response, and medical history, families should always follow the prescribed directions and the official leaflet.

Possible side effects mentioned
The original content lists the following possible side effects:

- Nausea and other gastrointestinal upset
It also notes that some children may experience changes in behaviour or mood. Any concerning or severe reaction should be discussed with a healthcare professional.
How Slenyto compares with other melatonin medicines
The source content compares Slenyto with Circadin. Both contain melatonin and are used to support sleep, but they are not presented as interchangeable.
Slenyto is described as a pediatric controlled-release formulation, while Circadin is described as being more commonly used in adults. If a family is comparing products, the official product information and a pharmacist’s advice are important because formulations and intended use can differ.
What to check before use
Before a child starts Slenyto, the original content highlights several points to review with a healthcare professional:
- Whether Slenyto is appropriate for the child’s situation
- Any other medicines or supplements the child is taking
- Whether sleep problems may have other causes
- Whether follow-up is needed to monitor response
The source also says monitoring is important, especially if there are renal or hepatic concerns.
Practical points for caregivers
According to the original content, Slenyto should be given at the same time each night and in a calm bedtime routine. It also says the tablet should not be crushed, because it is designed for controlled release.
If the medicine is difficult to give, the official leaflet or a pharmacist can help explain the correct administration method.
