What is Slenyto

Slenyto is a medication that contains the active ingredient melatonin. Melatonin is a hormone produced naturally by the body.

What is it used for

Slenyto is used to treatinsomnia(inability to fall asleep) in:

• children and adolescents(ages 2 to 18) withautism spectrum disorder (ASD)and/orneurogenetic disorders(hereditary conditions affecting the nerves and brain) associated with abnormal melatonin levels and/or nighttime awakenings, if other healthy sleep routines (e.g., a regular bedtime and a relaxing sleep environment) have not been sufficient.
• children and adolescents(ages 6 to 17)withattention deficit hyperactivity disorder (ADHD), if other healthy sleep routines (e.g., a regular bedtime and a relaxing sleep environment) have not been sufficient.

Slenyto shortens the time it takes to fall asleep and prolongs the duration of sleep.

The medication may help you or your child fall asleep and may help you or your child sleep for a longer period during the night.

Do not take Slenyto if you or your child:

• are allergic to melatonin or any of the other components of this medication (listed in section 6).

• has an autoimmune disease (in which the body's defense system attacks parts of the body). Consult your doctor before taking/administering Slenyto, as its use is not recommended in such cases.

Slenyto may cause drowsiness and daytime fatigue. Caregivers should monitor the child for signs of daytime fatigue and seek advice from your doctor if symptoms appear.

Particularly, children and adolescents with ADHD may experience an increase in daytime symptoms such as inattention, hyperactivity, or behavioral alterations.
