Methylphenidate is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in adults and children.

What does methylphenidate do to a normal person?

Ritalin influences both dopamine and norepinephrine activity in your brain. Dopamine is a neurotransmitter that affects pleasure, movement, and attention span. Norepinephrine is a stimulant. Ritalin increases the action of these neurotransmitters by blocking their reabsorption into your brain's neurons.

How does methylphenidate make you feel?

As stimulant drugs, methylphenidate and the methylphenidate-based drugs can make you feel very 'up', awake, excited, alert and energised, but they can also make you feel agitated and aggressive. They may also stop you from feeling hungry.
