Information about Armodafinil

Armodafinil is commonly used to treat sleep-related disorders. It helps manage symptoms of excessive daytime sleepiness.

Armodafinil works by affecting certain substances in the brain that control the sleep-wake cycle.

It increases the release of neurotransmitters like dopamine, which helps improve alertness and reduce sleepiness.

This action supports staying awake during the day and maintaining normal sleep patterns at night.

Not everyone experiences side effects, and many are mild and temporary. However, it’s important to be aware of them.

If you experience serious or persistent side effects, contact your healthcare provider.
