Modalert 200 is used to help people with narcolepsy, a condition that makes them sleepy during the day. It helps people stay awake all day long.

Narcolepsy is a long-term neurological disorder that makes it hard for the brain to control when you sleep and when you wake up.

People with narcolepsy may feel rested when they wake up, but they may feel very tired for most of the day.

Many people with narcolepsy also have trouble sleeping, which can cause them to wake up several times during the night.

Narcolepsy can make it hard to do things every day. People can fall asleep even when they don't want to, such as when they are driving, eating, or talking.

When you take Modalert, you will feel less tired and sleepy and be able to get back to your normal life.

Other symptoms include sudden muscle weakness while awake that makes a person go limp or unable to move (cataplexy), vivid dream-like images or hallucinations, and total paralysis right before falling asleep or right after waking up (sleep paralysis).
