Key Uses
- The medication is indicated to improve wakefulness in adults with these conditions.
- It is available in 50, 150, 200, and 250 mg tablets and is typically taken orally once daily, with or without food 1.
Dosage and Administration
- The recommended dose of Nuvigil is 150-250 mg taken orally once daily, and the duration of treatment is typically long-term.
- The dose may be adjusted based on individual patient response and tolerability.
Important Considerations
- Nuvigil is an FDA Schedule IV federally controlled substance because of its potential for abuse or dependency 1.
- It may cause fetal harm based on animal data, and human data are insufficient to determine risk 1.
- Armodafinil may reduce the effectiveness of oral contraception 1.
Side Effects
- Commonly reported adverse events include headache, upper respiratory tract infections, dizziness, nausea, sinusitis, and somnolence 1.

From the Research
Use of Nuvigil (Armodafinil)
- Nuvigil (armodafinil) is a wakefulness-promoting medication used to treat excessive sleepiness associated with obstructive sleep apnea, shift work disorder, or narcolepsy 3, 4, 5, 6.
- Armodafinil is the R-isomer of racemic modafinil and has a longer half-life, allowing for a longer duration of action 4, 5.
- The medication has been shown to be effective in improving wakefulness and reducing excessive daytime sleepiness in patients with these conditions 3, 4, 5, 6.
- Armodafinil is generally well tolerated, with common adverse events including headache, nasopharyngitis, and insomnia 3, 6.
- The safety profile of armodafinil is consistent with that of modafinil, and it is classified as a non-narcotic Schedule IV compound 5.
Mechanism of Action
- The exact mechanism of action of armodafinil is not fully understood, but it is thought to indirectly increase wakefulness by inhibiting cortical γ-aminobutyric acid (GABA) release via serotonergic mechanisms 7.
- Armodafinil may also increase wakefulness by increasing the activity of neurotransmitters such as dopamine and norepinephrine 7.
Clinical Efficacy
- Armodafinil has been shown to be effective in reducing excessive daytime sleepiness and improving wakefulness in patients with narcolepsy, obstructive sleep apnea, and shift work disorder 3, 4, 5, 6.
- The medication has also been shown to improve cognitive function and reduce the risk of accidents and injuries associated with excessive sleepiness 6.
