Frequently asked questions

Will it change my child's personality?

At the right dose it should not. If your child seems flat or very withdrawn, tell your doctor, as the dose may need adjusting.

Why might my child's growth be checked?

Reduced appetite can slow growth a little. Doctors monitor height and weight and sometimes suggest breaks from treatment.

Is methylphenidate addictive?

When taken as prescribed for ADHD the risk is low, but it can be misused, so it is a controlled medicine.
