Methylphenidate: Uses, Dosage, Side Effects & Precautions

Uses
Methylphenidate is a central nervous system (CNS) stimulant primarily used to treat:

1. Attention Deficit Hyperactivity Disorder (ADHD): It helps improve focus, attention, and impulse control.
2. Narcolepsy: It manages excessive daytime sleepiness and sudden sleep attacks.

It works by increasing the levels of dopamine and norepinephrine in the brain, which are important for attention and behavior regulation.
