Modvigil 100 mg

Modvigil 100 mg is a tablet that contains modafinil. It is formulated to promote wakefulness in adults who have troublesome daytime sleepiness due to particular sleep disorders.

Modafinil is described as a eugeroic meaning a medicine that encourages wakefulness. It acts on the central nervous system but it is not meant to replace adequate sleep or be used casually for tiredness, exam preparation or extended work hours. 

How does Modvigil 100 mg work?

The brain uses some chemical signals to control sleep and alertness. Modafinil alters some of these signals. These include dopamine, norepinephrine, histamine and orexin. These pathways help to keep attention focused and the body awake at the appropriate times.

Its exact effect is still not fully understood. In people with diagnosed excessive daytime sleepiness, Modvigil 100 mg may help them stay awake for longer and reduce unintended sleep episodes. It does not treat the root cause of a sleep disorder.

Key Features

Composition

Active ingredient: Modafinil 

Inactive ingredients: Croscarmellose sodium, Povidone, Magnesium stearate, Pregelatinized starch, Lactose Monohydrate and Microcrystalline cellulose

What is it used for?

Modavigil 100 mg is commonly recommended for excessive daytime sleepiness associated with:

• Obstructive sleep apnoea where daytime sleepiness remains despite suitable treatment for the breathing problem
• Shift work sleep disorder when work schedules interfere with the normal sleep wake cycle
• Narcolepsy which may cause sudden and difficult-to-control sleep attacks

For obstructive sleep apnoea, modafinil is not a treatment for airway obstruction. Continue CPAP therapy or other treatments recommended by your sleep specialist.

Dosage 

Use Modavigil 100 mg exactly as your doctor has instructed. The dose and timing are based on the condition being treated your other medicines, health conditions and response to therapy.

For some people, 100 mg may be suggested once daily. It is often taken in the morning to manage narcolepsy or sleepiness related to obstructive sleep apnoea. If it is prescribed for shift work sleep disorder a doctor may advise taking it approximately one hour before a scheduled shift.

Swallow the tablet with water. It can generally be taken with or without food but eating beforehand may delay how quickly it begins to work. Avoid late-day doses unless your doctor has advised otherwise as this may disrupt normal sleep. Do not take more than prescribed and never take two doses together to compensate for a missed one.
