⚡ Quick Answer — What is Modvigil 200 mg?
Modvigil 200 mg bevat modafinil as an oral tablet from HAB Pharma — a eugeroic wakefulness-promoting agent (the parent drug of the modafinil class). FDA-approved for the treatment of excessive daytime sleepiness associated with narcolepsy, shift work sleep disorder (SWSD), en residual sleepiness in treated obstructive sleep apnea (OSA). Onset: 30-60 minutes after an oral dose taken fasting (food delays absorption by 1-2 hours but does not reduce total exposure). Peak plasma concentration at 2-4 hours. Duration of wakefulness effect: 10-12 hours for the 200 mg dose. 200 mg once daily in the morning is the standard dose for narcolepsy and residual OSA sleepiness. For shift-work sleep disorder, take 200 mg 1 hour before the start of the shift. Some patients respond adequately to 100 mg; others need a total daily dose of 400 mg split as 200 mg morning + 200 mg at noon (for long-duration alertness needs). Specialist-supervised. Schedule IV controlled substance (US DEA); schedule varies internationally. CRITICAL: Modafinil is a CYP3A4 inducer that reduces the effectiveness of hormonal contraceptives — women of childbearing potential MUST use non-hormonal backup contraception (condoms, copper IUD, or abstinence) during treatment and for 1 maand na de laatste dosis. Common side effects: headache, nausea, insomnia if dosed too late. STOP immediately and seek urgent medical advice if you develop any rash — rare but severe Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and DRESS reactions have been reported.

What Is Modvigil 200 mg?
Modvigil 200 mg is een oraal modafinil 200 mg tablet van HAB Pharma, supplied in pack sizes of 10 / 30 / 60 / 90 / 180 tablets. Modafinil is a wakefulness-promoting agent first approved by the FDA in 1998 (brand Provigil) for narcolepsy; subsequent approvals added shift-work sleep disorder (2004) and residual sleepiness in treated obstructive sleep apnea (2004).
Modafinil is a racemic mixture (50% R-modafinil and 50% S-modafinil). The R-enantiomer has a longer half-life (~15 hours) and drives most of the sustained wakefulness effect; the S-enantiomer has a shorter half-life (~3-4 hours) and contributes to the early onset “first-hit” feeling.
If you want the R-enantiomer-only form (armodafinil) for a smoother duration and lower early peak, see our Artvigil 150 mg page — the same HAB Pharma manufacturer, armodafinil rather than racemic modafinil.
How Does Modafinil Work?
The precise wakefulness mechanism of modafinil is not fully defined, but multi-system modulation is now well characterised:
- Weak dopamine transporter (DAT) inhibition — modafinil binds to DAT with relatively low affinity compared to classical stimulants (amphetamine, methylphenidate). This raises extracellular dopamine modestly in the nucleus accumbens, striatum and prefrontal cortex. The weaker binding is what gives modafinil its much lower abuse liability than amphetamines.
- Histaminergic activation — modafinil activates the tuberomammillary nucleus (the brain’s histamine-producing centre), increasing histamine release in the hypothalamus and cortex. Histamine is a key wake-promoting neurotransmitter, and this pathway is central to the sustained-wakefulness effect.
- Orexin/hypocretin system stimulation — modafinil activates orexin-releasing neurons in the lateral hypothalamus. Orexin deficiency is the underlying cause of type 1 narcolepsy; modafinil partly compensates for this deficit.
- Noradrenergic effect — modest inhibition of the norepinephrine transporter in the ventrolateral preoptic nucleus, supporting arousal.
- Selective for wake circuits, not reward circuits — unlike amphetamine-class stimulants, modafinil does not produce significant euphoria or reinforcement in most users at therapeutic doses. This selectivity is the basis of its Schedule IV (rather than Schedule II) classification.
- Metabolism — hepatic, primarily via CYP3A4 and minor CYP2C19 pathways. Modafinil is itself a CYP3A4 inducer (this is the mechanism behind the contraceptive interaction) and a weak CYP2C19 inhibitor.
- Renal excretion — primarily as inactive metabolites; <10% unchanged drug.
Modafinil does not reduce the biological need for sleep. It suppresses the subjective experience of sleepiness during its duration of action, but sleep debt accumulates normally. Chronic use without sufficient night-time sleep (7-8 hours for most adults) is harmful and will eventually manifest as cognitive, immune, cardiovascular and metabolic deterioration.
When Modvigil Is Used
FDA-approved indications
- Narcolepsy — the primary FDA-approved indication. Modvigil reduces excessive daytime sleepiness, improves alertness on objective (Maintenance of Wakefulness Test, MWT) and subjective (Epworth Sleepiness Scale) measures. Does niet treat cataplexy; for narcolepsy with cataplexy, Modvigil is combined with sodium oxybate, pitolisant or SSRIs.
- Shift-work sleep disorder (SWSD) — excessive sleepiness during the night-shift work period. Modvigil is FDA-approved for SWSD; dose is taken 1 hour before shift start.
- Residual sleepiness in treated obstructive sleep apnea — for patients adherent to CPAP/BiPAP with persistent excessive daytime sleepiness despite optimal airway treatment. Modvigil is an adjunct, NOT a replacement for CPAP.
Off-label clinical uses
- ADHD — some randomised trials support modafinil for adult ADHD. Not FDA-approved for this indication in adults or children, and paediatric use has been specifically cautioned against by the FDA after SJS case reports in children.
- Multiple sclerosis fatigue — some evidence of benefit; often used off-label in specialist MS clinics.
- Depression augmentation — small controlled trials support addition of modafinil to antidepressants in treatment-resistant depression with prominent fatigue.
- Cancer-related fatigue, chemotherapy fatigue — modest benefit in specialist oncology settings.
- Parkinson’s disease daytime sleepiness — used specifically for Parkinson’s-associated EDS.
- Jet lag and long-haul flight fatigue — occasional short-term use; not a routine or primary indication.
Uses that are NOT appropriate
Modvigil is niet appropriate for:
- Simple tiredness or fatigue without an underlying sleep disorder diagnosis. Proper sleep hygiene, adequate night-time sleep, and evaluation of underlying cause (anaemia, thyroid disease, depression, sleep apnea) come first.
- General “cognitive enhancement” or study aid in healthy people without a sleep or ADHD diagnosis. While popular in this use pattern, it is off-label, unmonitored, and carries real (if rare) risks including SJS, psychiatric reactions, and dependence with daily long-term use.
- Substitute for adequate sleep — does not replace the biological recovery functions of sleep.
- Paediatric sleep disorders — use in children is not FDA-approved and is specifically cautioned against due to SJS case reports.
- Gewichtsverlies — despite mild appetite-suppressant effects in some users, this is not an appropriate indication.
Modvigil Dose and How to Take
Standard dosing
- Narcolepsy or residual OSA sleepiness: 200 mg once daily in the morning, taken on an empty stomach or with a light breakfast.
- Shift-work sleep disorder: 200 mg taken approximately 1 hour before the start of the night shift.
- Elderly patients (>65 years): consider starting at half dose (100 mg).
- Ernstige leverfunctiestoornis: reduce dose by 50% (100 mg daily).
- Severe renal impairment: dose-adjustment not formally established; use with caution and monitor closely.
Higher doses and titration
200 mg of modafinil is approximately equivalent to 150 mg of armodafinil in wakefulness effect, though with a different time-profile (modafinil has a sharper peak; armodafinil has smoother sustained alertness). Some patients with severe narcolepsy or SWSD respond adequately only to 400 mg daily (given as 200 mg AM + 200 mg at noon) — this has been shown in controlled trials to be non-superior on average but can benefit individual patients. Splitting the dose (morning + midday) is preferred over a single larger morning dose because it reduces risk of evening sleep disruption.
Timing rules
- Take in the morning — modafinil taken after 10 AM commonly interferes with sleep that same evening. Take as early as practical after waking.
- Do not take late in the day even if you plan to stay up. Sleep debt accumulates whether you are aware of it or not.
- In te nemen met of zonder voedsel — food delays onset by 1-2 hours but does not reduce total exposure. Fasting gives a faster onset.
- Do not crush or split unless prescribed — these tablets are not scored for pharmacy-grade splitting. If a lower dose is needed, talk to your prescriber about the appropriate-strength tablet.
- Do not combine with other stimulants (amphetamines, methylphenidate, high-dose caffeine) without medical supervision — additive cardiovascular and psychiatric risks.
Duration of treatment
For narcolepsy, Modvigil is typically a long-term daily treatment, used indefinitely as clinically indicated. For SWSD, it is used while the shift-work pattern continues; no need to taper on stopping. For OSA, it is an adjunct to airway treatment; if the airway treatment normalises sleepiness, Modvigil can be discontinued. For off-label or episodic use, it should be used sparingly and only with medical supervision.
Bijwerkingen
Common (>5% of users)
- Hoofdpijn — the most common; usually mild, often responds to hydration and paracetamol
- Misselijkheid, mild gastrointestinal upset
- Insomnia or delayed sleep onset — if dosed too late
- Anxiety, jitteriness — particularly in the first week
- Duizeligheid
- Dry mouth, decreased appetite
- Rhinitis, pharyngitis — reported in clinical trials
Less common (1-5%)
- Palpitations, tachycardia, mild hypertension — monitor blood pressure, particularly if pre-existing cardiovascular disease
- Diarrhoea, dyspepsia
- Chest pain (non-cardiac, usually) — evaluate any persistent or exertional chest pain
- Back pain, musculoskeletal aches
- Paresthesie
Rare but serious — STOP immediately and seek urgent medical advice
- Severe skin reactions — Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS). These are rare (estimated 1 in ~5,000 users) but can be fatal. Symptoms: any rash, fever, flu-like feeling, blistering, mucous membrane involvement (mouth, eyes, genitals). Stop the drug immediately and seek urgent medical attention for ANY rash — do not wait to see if it progresses. The FDA specifically warned against paediatric use because of paediatric SJS cases.
- Serious psychiatric reactions — mania, hypomania, psychosis, suicidal ideation, aggression. Higher risk in patients with history of bipolar disorder, psychosis, or prior similar reactions to stimulants.
- Angio-oedeem or anaphylaxis — rare.
- Ernstige cardiovasculaire gebeurtenissen (arrhythmia, MI) — rare at therapeutic doses; higher risk in pre-existing structural heart disease, severe hypertension, or in combination with other stimulants.
Contra-indicaties & waarschuwingen
- Known hypersensitivity to modafinil, the other enantiomer (armodafinil), or any excipient
- History of severe skin reaction (SJS, TEN, DRESS) with modafinil or modafinil/armodafinil — absolute
- History of mania, psychosis, or severe bipolar disorder — relative contraindication; specialist decision
- Unstable angina, recent myocardial infarction, severe uncontrolled hypertension, severe left ventricular hypertrophy, mitral valve prolapse with stimulant-induced chest pain — avoid or specialist cardiology decision
- Pregnancy (Category C) — teratogenic in rodent studies; human case reports suggest increased risk of congenital heart defects and hypospadias. Vermijd tijdens zwangerschap. Effective non-hormonal contraception is mandatory during treatment and 1 month after the last dose (see below).
- Borstvoeding — limited data; excreted in rodent milk; generally avoided in breastfeeding
- Paediatric use — not FDA-approved; specifically cautioned because of paediatric SJS cases in the 2006-2007 post-marketing surveillance
- Ernstige leverfunctiestoornis — reduce dose by 50%
- History of substance use disorder, especially stimulants — use cautiously under monitoring; abuse liability is low but non-zero
Critical Interaction — Hormonal Contraceptives
Women of childbearing potential must use non-hormonal backup contraception during Modvigil treatment and for at least 1 month after the last dose (to allow for full clearance of CYP3A4 induction):
- Condoms (male or female) — simplest reliable backup
- Copper IUD (ParaGard, copper T) — non-hormonal, not affected by CYP3A4 induction
- Abstinence
- Surgical sterilisation (tubal ligation, vasectomy in the partner)
Hormonal contraceptives alone are NOT reliable on modafinil. This interaction has caused real contraceptive failures and unplanned pregnancies; given the pregnancy risk of modafinil itself, these are particularly high-stakes. If you develop pregnancy symptoms during treatment, test immediately.
Other Drug Interactions
| Drug class | Effect |
|---|---|
| Other stimulants (amphetamines, methylphenidate, high-dose caffeine, cocaine) | Additive cardiovascular (tachycardia, hypertension) and psychiatric (anxiety, mania) effects. Avoid or combine only under specialist supervision. |
| MAOIs | Avoid — risk of hypertensive crisis |
| Warfarine | Modest CYP2C9 inhibition — monitor INR more closely for first 2-4 weeks of modafinil |
| Cyclosporine, tacrolimus, sirolimus | Reduced levels via CYP3A4 induction — transplant monitoring essential |
| Protease inhibitors (HIV), many antiepileptics | Bidirectional effects via CYP3A4; specialist advice required |
| Tricyclische antidepressiva | Possible increase via CYP2C19 inhibition; monitor clinically |
| SSRIs/SNRIs | Generally manageable; monitor for serotonergic side effects |
| Phenytoin, carbamazepine, phenobarbital | Reduce modafinil levels via CYP3A4 induction — may need dose increase |
| Clopidogrel | Reduced activation via CYP2C19 inhibition — possible reduced antiplatelet effect |
| Alcohol | Alcohol can delay or mask awareness of drowsiness. Avoid heavy alcohol use while on modafinil |
Modvigil vs Other Modafinil Brands
Modvigil is one of several branded generics of modafinil 200 mg. All contain the same active pharmaceutical ingredient at the same strength; the practical differences are in manufacturer reputation, excipient profile, and price.
| Brand | Opmerkingen |
|---|---|
| Modvigil (HAB Pharma) | Generic modafinil 200 mg. Workhorse generic used by the nootropic and narcolepsy communities. Equal active content to Modalert and Provigil. |
| Modalert (Sun Pharma) | Other major generic modafinil. Same active, slightly different excipient profile. Often described as slightly more “peaky”. |
| Modaheal (Healing Pharma) | Third major generic modafinil. Equivalent active content. |
| Provigil (Teva / Cephalon) | Original branded modafinil. Same active. Substantially higher retail price outside generic markets. |
Because all modafinil 200 mg tablets contain the same active, the clinical effect is identical. Individual reports of “this brand feels different from that brand” almost always reflect batch variation, excipient sensitivity, or expectation effect rather than pharmacological difference. If you have a verified hypersensitivity to a specific excipient, that is worth matching — otherwise, brand choice is a cost and supply-chain decision.
Modafinil vs Armodafinil — Which Should You Choose?
The pharmacological differences between modafinil and armodafinil are subtle, and the two drugs are often interchangeable for the same clinical indication. The practical differences:
- Begin: modafinil 30-60 minutes; armodafinil 1-2 hours. If you need a fast wake-up, modafinil wins.
- Duration: modafinil 10-12 hours of functional wakefulness; armodafinil 12-15 hours. If you need longer-duration alertness (double shift, long flight, extended work session), armodafinil wins.
- Peak profile: modafinil has a sharper initial peak (the S-enantiomer contributes) and can feel more “on”; armodafinil has a smoother, more sustained feel without the early peak. Patients prone to anxiety often prefer armodafinil.
- Equivalent dose: modafinil 200 mg ≈ armodafinil 150 mg for wakefulness magnitude. Do not dose both on the same day.
- Sleep-onset in the evening: armodafinil’s longer half-life can delay sleep if taken too late in the morning; switch to modafinil if your workday ends late.
- Cost: armodafinil (Artvigil, Waklert, Armodapro) is typically modestly more expensive per tablet than modafinil, but at the equivalent dose the per-dose cost is similar.
Clinicians often start patients on modafinil 200 mg and switch to armodafinil 150 mg if the patient reports an early-afternoon “crash” or wants a smoother profile. Conversely, patients on armodafinil who need faster onset sometimes switch back to modafinil.

Veelgestelde vragen
Is modafinil addictive?
Modafinil has a much lower abuse liability than classical stimulants (amphetamine, methylphenidate). This is why it is Schedule IV (rather than Schedule II) in the US. However, it is not zero — psychological dependence can develop with daily long-term use. Physical withdrawal on stopping is usually mild: rebound sleepiness, low energy, mild low mood for a few days. Patients with a history of stimulant abuse should use under specialist supervision.
Do I need a prescription for modafinil?
Yes. Modafinil is a specialist-supervised Schedule IV controlled substance in the US, the UK, most EU countries, Australia, Canada, and other major jurisdictions. You should have a diagnosis of narcolepsy, shift-work sleep disorder, residual OSA sleepiness, or another clinically indicated off-label condition, and a prescriber monitoring your treatment.
How long does modafinil last?
Oral modafinil has an onset of 30-60 minutes after a fasting dose (longer with food), peak plasma concentration at 2-4 hours, and functional wakefulness effect of 10-12 hours for the 200 mg dose. Elimination half-life is approximately 12-15 hours (R-enantiomer 15h, S-enantiomer 3-4h). Taking the tablet too late in the morning can interfere with that evening’s sleep.
Does modafinil work for ADHD?
Some randomised controlled trials support modafinil as an alternative for adult ADHD, particularly in patients who cannot tolerate or have contraindications to classical stimulants. It is not FDA-approved for this use. In paediatric ADHD, modafinil is specifically cautioned against because of the paediatric SJS case reports. If you are considering modafinil for ADHD, have that conversation with a psychiatrist experienced in ADHD rather than using it off-label without supervision.
Does modafinil help with depression?
Several small randomised trials have shown benefit when modafinil is added to a standard antidepressant in patients with treatment-resistant depression that has prominent fatigue and daytime sleepiness. It is not a standalone antidepressant and should not replace first-line depression treatment. Specialist psychiatry supervision is appropriate for this off-label use.
Can I take modafinil with coffee?
Moderate caffeine intake (1-2 cups of coffee) is generally compatible with modafinil, but the two are additive for cardiovascular (tachycardia, palpitations) and psychiatric (anxiety, jitteriness) effects. If you feel jittery or anxious on modafinil, reduce your caffeine intake before increasing the dose of modafinil.
Will modafinil make me feel high or euphoric?
Most users at therapeutic doses (200 mg) describe modafinil as producing alertness and mental clarity without euphoria — very different from amphetamine-class stimulants. This is why it has relatively low abuse liability. At high supra-therapeutic doses or in susceptible individuals, mild mood elevation or anxiety can occur.
Can I stop Modvigil suddenly, or do I need to taper?
Modafinil does not require a formal taper — it can be stopped directly without physical withdrawal syndrome. You may experience rebound sleepiness, fatigue and mild low mood for a few days to a week; this resolves without intervention. For patients on long-term daily treatment, a short taper over a few days can smooth the transition.
Can I drink alcohol on modafinil?
Modafinil does not interact directly with alcohol in the liver, but alcohol can mask or delay the normal drowsiness signals that tell you to stop drinking. The combination can produce a false sense of sobriety followed by a sudden increase in intoxication when modafinil wears off. Avoid heavy alcohol use while on modafinil; moderate social drinking (1-2 units on an occasion) is generally tolerated.
What happens if I take modafinil with hormonal birth control?
Modafinil reduces the effectiveness of combined oral contraceptives, progestogen-only pills, hormonal patches, vaginal rings, and hormonal IUDs via CYP3A4 induction. You need non-hormonal backup contraception (condoms, copper IUD, abstinence) during treatment and for 1 month after stopping. Given that modafinil itself is pregnancy Category C, contraceptive failure is particularly high-stakes. Discuss with your prescriber before starting.
What should I do if I develop a rash on modafinil?
Stop the drug immediately and seek urgent medical attention. Modafinil has caused rare but severe and fatal Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and DRESS reactions. Early symptoms are any rash, fever, flu-like feeling, or mucous membrane involvement (mouth, eyes, genitals). Do not “wait and see”. This is the single most important safety rule for modafinil.
Can I use Modvigil long-term?
For narcolepsy, yes — Modvigil is typically a long-term daily treatment. Many patients have been on it for 10-20+ years without tolerance or clinically significant long-term toxicity at therapeutic doses. For other indications, duration depends on the clinical condition (SWSD: as long as the shift pattern continues; OSA: until airway treatment normalises sleepiness; off-label uses: as directed).
How is Modvigil different from caffeine?
Caffeine is an adenosine A1/A2A antagonist that produces short-duration alertness (4-6 hours) with tolerance that develops quickly. Modafinil acts through dopamine, histamine, orexin and norepinephrine pathways, produces much longer-duration wakefulness (10-12 hours), has minimal tolerance, and is dose-dependently effective for true sleep-disorder treatment. They are not interchangeable; modafinil is a regulated medicine for diagnosed conditions, whereas caffeine is a dietary stimulant.
Where can I order Modvigil online?
You can order Modvigil 200 mg from MedsBase in pack sizes of 10 / 30 / 60 / 90 / 180 tablets. Orders ship worldwide with discreet packaging. Modafinil is specialist-supervised in most jurisdictions; have your clinician’s diagnosis and treatment plan in place before ordering.
