Description
How does it Work?
Modvigil 100mg contains modafinil. It belongs to the group of most common stimulants. Stimulants are the kind of medicine that can make a person feel more awake, alert or energetic.
Modafinil works by decreasing the reabsorption of dopamine into nerves. Dopamine is a chemical messenger, used by nerves to send messages (signals) between the brain and body. Dopamine plays an important role in controlling sleep, mood, learning and focus. Modafinil increases the level of dopamine in the brain. This impacts the sleep-wake cycle, improving wakefulness, alertness and performance. It helps manage excessive daytime sleepiness due to narcolepsy.
Uses
- Narcolepsy
A disorder that makes people extremely sleepy or drowsy during the day
- Obstructive sleep apnea/hypopnea syndrome (OSAHS)
A breathing disorder that affects the upper airway during sleep
- Shift work sleep disorder (SWSD)
A sleep disorder that commonly affects people who work at night or often rotate shifts
Recommended Dose
For sleep disorders, take 1 Modvigil tablet orally with or without food as directed by your physician. It is usually taken once a day an hour before the work shift begins.
