Nuvigil is the brand name for armodafinil, a wakefulness-promoting medication (eugeroic) approved by the FDA in June 2007. It is used to treat excessive daytime sleepiness associated with narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD). Armodafinil is the R-enantiomer — the purified, more pharmacologically active half — of racemic modafinil (Provigil). This gives it a slightly longer half-life and potentially longer duration of effect.
Nuvigil was developed by Cephalon, now a Teva Pharmaceutical subsidiary. Generic armodafinil has been available since 2016 from manufacturers including Aurobindo and Mylan (Viatris). In March 2026, Breckenridge Pharmaceutical received FDA approval for its generic armodafinil tablets, adding a new manufacturer to the market.
Armodafinil is classified as a Schedule IV controlled substance by the DEA, indicating it has a recognized medical use but carries some potential for abuse and physical dependence — significantly lower than Schedule II stimulants like amphetamine or methylphenidate. It is available in 50 mg, 150 mg, 200 mg, and 250 mg oral tablets, with 150 mg and 250 mg being the most commonly prescribed strengths.

Armodafinil promotes wakefulness primarily by inhibiting the dopamine transporter (DAT) in the brain. By blocking the reabsorption of dopamine, it increases extracellular dopamine levels, which promotes alertness and reduces excessive sleepiness. This makes it an atypical dopamine reuptake inhibitor (DRI). Unlike traditional stimulants like amphetamines, armodafinil does not cause a massive flood of dopamine release, which explains its lower abuse potential and more controlled wake-promoting effect.
Research also suggests armodafinil may affect norepinephrine, histamine, and orexin pathways in the brain, though the full mechanism is not completely understood. Because armodafinil is the R-enantiomer of modafinil, it reaches higher plasma concentrations later in the day compared to racemic modafinil, providing a more sustained wakefulness effect for some patients. Peak plasma concentration is reached approximately 2 hours after dosing on an empty stomach.
Armodafinil also induces CYP3A4 enzymes in the liver (moderately) and inhibits CYP2C19, which affects the metabolism of many other medications. This is why it has important drug interactions — particularly with hormonal contraceptives (reduced effectiveness), cyclosporine (reduced immunosuppressant levels), warfarin (increased anticoagulation), and MAO inhibitors (contraindicated — risk of hypertensive crisis).

200 mg — oral tablet
Mid-range dose for narcolepsy and OSA
250 mg — oral tablet
Maximum approved dose; used for narcolepsy and OSA when lower doses are insufficient
Nuvigil scores a 65 out of 100 on our findability scale, indicating intermittent availability issues. While armodafinil is not on any formal FDA or ASHP drug shortage list as of early 2026, patients regularly report difficulty finding it at their local pharmacies — particularly at large chain pharmacies. The supply issues stem from DEA Schedule IV manufacturing quotas, a limited number of generic manufacturers, rising demand from off-label prescribing, and international supply chain complexity.
The 150 mg and 250 mg strengths are most commonly prescribed and may be harder to find. Independent and specialty pharmacies typically have better availability than chain pharmacies, as they use different wholesalers and are not subject to the same corporate ordering caps. Mail-order pharmacies maintain larger inventories and are generally more reliable for long-term patients.
If you're struggling to find armodafinil at your pharmacy, medfinder can help you locate pharmacies near you that have it in stock — saving you the hassle of calling around. medfinder calls pharmacies on your behalf and texts you the results.
Because armodafinil is a Schedule IV controlled substance, it can be prescribed by any licensed healthcare provider with prescriptive authority for controlled substances in their state. No special DEA waiver or certification is required beyond the standard DEA registration that most prescribers hold.
Sleep medicine specialists — primary prescribers for narcolepsy and OSA
Neurologists — narcolepsy, MS-related fatigue
Psychiatrists — off-label uses: ADHD, depression-related fatigue, bipolar depression adjunct
Pulmonologists — OSA-related excessive sleepiness
Primary care physicians (PCPs) and internists — any approved indication
Nurse practitioners (NPs) and physician assistants (PAs) — in most states, with prescriptive authority for Schedule IV substances
Telehealth prescribing of armodafinil is available in many states, making access more convenient — especially for patients with shift work sleep disorder, where a formal sleep study is typically not required for diagnosis. Telehealth platforms specializing in sleep medicine can evaluate patients and issue or renew prescriptions online.
Yes. Nuvigil (armodafinil) is classified as a Schedule IV controlled substance by the DEA. This means it has a recognized medical use but also a recognized potential for abuse and physical dependence. Schedule IV is the second-lowest controlled substance classification — significantly less restrictive than Schedule II medications like Adderall (amphetamine) or Ritalin (methylphenidate).
As a Schedule IV controlled substance, armodafinil prescriptions are subject to the following rules in most states: up to 5 refills within 6 months, prescriptions cannot be called in as verbal orders in all states, state-specific restrictions on transfers between pharmacies, and DEA-regulated production quotas that limit how much can be manufactured annually. These quotas are a primary driver of the intermittent pharmacy stockouts patients experience.
Physical dependence can develop with long-term use, and abrupt discontinuation following chronic use can cause withdrawal symptoms including fatigue, shaking, sweating, nausea, and anxiety. Always discuss stopping armodafinil with your prescriber rather than stopping abruptly after prolonged use.
The most frequently reported side effects from clinical trials include:
Headache (most common)
Nausea
Dizziness
Insomnia (especially if taken too late in the day)
Dry mouth (xerostomia)
Anxiety or nervousness
Decreased appetite
Small increases in blood pressure and heart rate (average 1–4 mmHg and 1–4 bpm)
Stevens-Johnson Syndrome (SJS) / Toxic Epidermal Necrolysis (TEN): Rare but life-threatening skin reactions
DRESS syndrome: Drug Reaction with Eosinophilia and Systemic Symptoms — multi-organ hypersensitivity
Anaphylaxis / angioedema: Severe allergic reactions
Psychiatric symptoms: Hallucinations, mania, depression, suicidal thoughts
Cardiovascular events: Chest pain, significant blood pressure elevation, arrhythmia

moderateThese CYP3A4 inducers can increase armodafinil metabolism, potentially reducing its effectiveness. Dose adjustment may be required.
Nuvigil (armodafinil) is a well-established, effective wakefulness-promoting medication with a favorable safety profile compared to traditional stimulants. It is FDA-approved for three sleep disorders and widely used off-label for conditions involving fatigue. The generic version is bioequivalent to Nuvigil and available at a fraction of the cost — with discount coupons, as low as $30–$80 per month.
While not on any formal FDA shortage list, armodafinil availability can be inconsistent at some pharmacies due to DEA quota constraints and a limited number of generic manufacturers. The addition of Breckenridge Pharmaceutical as a new generic manufacturer in March 2026 is a positive development that should improve supply over time. Independent pharmacies and mail-order remain the most reliable sources for patients experiencing stock issues at chain pharmacies.
