What is the generic name for modafinil?
The generic name for the prescription medication Provigil is modafinil. A generic drug contains the same active ingredient as its brand-name counterpart and is considered bioequivalent, meaning it works the same way and provides the same therapeutic effect. Generic versions are typically more affordable once brand-name patents expire.
Understanding Generic vs. Brand-Name Medications
Brand-name drugs, like Provigil, are the first versions of a medication developed and patented. Once the patent expires, other manufacturers can produce generic versions. The FDA requires generics to be bioequivalent, ensuring they are just as safe and effective as the original brand-name drug. Generics are more affordable because manufacturers don't have to repeat costly clinical trials, and competition further lowers prices.
How Modafinil Works in the Body
Modafinil is a central nervous system (CNS) stimulant or wakefulness-promoting agent, though its exact mechanism is not fully understood. It is thought to work by inhibiting the reuptake of dopamine and affecting other neurotransmitters like histamine and orexin.
What is modafinil prescribed for?
Modafinil is FDA-approved to improve wakefulness in adults with excessive daytime sleepiness from specific conditions:
- Narcolepsy: Characterized by overwhelming daytime drowsiness and sudden sleep attacks.
- Obstructive Sleep Apnea (OSA): Used as an adjunct to standard treatments like CPAP.
- Shift Work Disorder (SWSD): Affects those working non-traditional hours.
Modafinil manages excessive sleepiness but does not cure these underlying disorders. It is also used off-label for other conditions, though not FDA-approved for these uses.
Common and Serious Side Effects
Modafinil can cause side effects.
Common Side Effects:
- Headache
- Nausea
- Nervousness or anxiety
- Insomnia
Serious Side Effects:
- Severe Rash: Rare but serious reactions like Stevens-Johnson syndrome can occur. Seek immediate medical help for any rash.
- Psychiatric Symptoms: Mood changes, anxiety, or hallucinations are possible.
- Cardiovascular Effects: Increased heart rate or blood pressure, especially in those with existing heart conditions.
Drug Interactions and Precautions
Modafinil is a Schedule IV controlled substance due to potential for misuse and dependence. Precautions include:
- Hormonal Contraceptives: Modafinil can reduce their effectiveness. Use backup birth control during and for one month after treatment.
- CYP Enzymes: Modafinil affects drug metabolism. Review all medications with your doctor.
- Alcohol and Caffeine: Limit intake to avoid exacerbating side effects.
- Driving/Machinery: Exercise caution until you know how modafinil affects you.

Conclusion
The generic name for Provigil is modafinil. Generic modafinil is therapeutically equivalent to the brand-name version, offering the same effectiveness for treating excessive daytime sleepiness associated with narcolepsy, OSA, and SWSD. The primary advantage of generic modafinil is its lower cost. Regardless of whether you use brand-name or generic, follow your doctor's instructions, be aware of side effects, and understand drug interactions, particularly with hormonal birth control. Discuss your options with your healthcare provider and insurer to determine the best choice for your needs.
