About Methylphenidate For Adults

Methylphenidate is used to treat attention deficit hyperactivity disorder (ADHD). It's also sometimes used to treat narcolepsy.

Methylphenidate belongs to a group of medicines called stimulants. They work by increasing activity in the brain, particularly in areas that help control attention and behaviour.

It comes as standard tablets. It also comes as slow release tablets and capsules which release the medicine into your body gradually. If your medicine says modified release or sustained release on the packet, this means that they are also slow release.

Methylphenidate is available on prescription only.

Key facts

• Methylphenidate is a controlled drug, which means that you may have to prove your identity when collecting your prescription. You also have to collect your prescription within 28 days.
• You'll usually take standard tablets 2 to 3 times a day. If you're taking slow release methylphenidate, you'll usually take it once a day.
• Side effects can include headaches and sleep problems.
• It usually takes a few weeks for methylphenidate to work fully. It can take time to find the right type and dose. Once you do, it should start to work within 30 to 60 minutes of taking it.
• It's best to stick to the same brand of methylphenidate. Different brands work differently in how they release the medicine into your body, and this can affect how they work to manage your symptoms.
• Do not stop taking methylphenidate suddenly without speaking to your doctor.
