Patient leaflet - Adaflex Ava 0.5 mg tablets

1. What adaflex ava is and what it is used for

The active substance of adaflex ava, melatonin, belongs to a group of natural hormones produced by the body. The hormone helps regulate the body’s day- and night rhythm.

adaflex ava is used for:

Insomnia in children and adolescents (6 to 17 years old) with attention deficit hyperactivity disorder (ADHD), where other healthy sleeping routines have not worked well enough.
Delayed sleep-wake phase disorder (DSWPD) (disruption of the body’s day and night rhythm) in children and adolescents (6 to 17 years old) and adults up to 25 years of age, where healthy sleeping routines have not worked well enough.
Short-term treatment of jet lag in adults. Jet lag refers to the symptoms caused by the time difference when travelling across several time zones.

Pregnancy

adaflex ava is not recommended if you are pregnant. Melatonin crosses the placenta and there is insufficient information on the risk this may pose to the unborn child.

Breast-feeding

adaflex ava is not recommended if you are breast-feeding. Melatonin passes into human milk, and a risk to the breast-fed child cannot be excluded.

adaflex ava can make you feel drowsy. If this happens, you must not drive or operate machinery.

adaflex ava contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

3. How to take adaflex ava

Insomnia in children and adolescents with ADHD

Melatonin treatment is prescribed by your doctor because other treatable causes of the sleep disorder have been ruled out and other sleep-promoting measures have been insufficient.

Treatment should be followed up regularly by a doctor to see if it is still appropriate. For some patients, treatment can be continued past the usual age ranges if it is considered appropriate.

Adults with jet lag

The standard starting dose is 3 mg daily for a maximum of 5 days. The dose can be gradually adjusted within the range of 0.5 mg to 5 mg per day to alleviate your symptom. The lowest dose that alleviates your symptom should be used for the shortest time. Maximum treatment time is 5 days.
