Methylphenidate

ADHD and focus

Also known as Ritalin, Concerta

Methylphenidate is a stimulant used for ADHD. It boosts certain brain chemicals that help you focus, sit with a task, and think before acting. It works quickly — often the same day — but the honest part is that it has a high potential for abuse and dependence, which is why it comes with an FDA boxed warning and strict refill rules. Take it exactly as prescribed and it can be genuinely life-changing.

How to take it

When

In the morning — afternoon or evening doses can wreck your sleep.

Food

Appetite loss is common. Eat breakfast before your dose and protect your meals.

Avoid

Never share it with anyone — it's illegal and dangerous. Store it somewhere secure.

Good to know

Tell your doctor about any personal or family history of heart problems before starting.

Missed a dose?

If you remember early in the day, take it then. If it's already afternoon, skip it — a late dose will keep you up at night. Never double up.
