Artvigil 150mg is a product described as containing 150mg of armodafinil, a wakefulness-promoting medicine. Armodafinil is closely related to modafinil and is used in some countries to manage excessive daytime sleepiness associated with diagnosed sleep disorders.
Armodafinil is also the active ingredient in Nuvigil, a medicine authorised in the United States. However, medicines containing the same active ingredient are not automatically identical in their manufacturing standards, regulatory approvals or clinical interchangeability.
Important UK information: The UK marketing authorisation of Artvigil 150mg has not been independently established here. Approval of armodafinil medicines in the United States does not automatically permit the marketing or supply of Artvigil in the UK.
What Is Artvigil 150mg?
Artvigil 150mg is a named armodafinil product with a declared strength of 150mg per tablet. Armodafinil is classified as a wakefulness-promoting agent, sometimes called a eugeroic.
Armodafinil is the R-enantiomer of modafinil. It acts on brain systems involved in regulating wakefulness, although its complete mechanism of action remains incompletely understood.
In the United States, authorised armodafinil medicines are used to improve wakefulness in adults with excessive sleepiness associated with narcolepsy, obstructive sleep apnoea or shift work disorder.
These indications are based on US prescribing information and should not be interpreted as confirmation of UK approval for Artvigil.
Artvigil 150mg Product Information
How Does Artvigil 150mg Work?
Armodafinil promotes wakefulness by affecting neurotransmitter signalling in the central nervous system. Its precise mechanism is not fully understood.
One recognised component involves inhibition of dopamine reuptake, which affects dopamine availability in brain pathways involved in wakefulness.
Other neurotransmitter systems may also contribute to the effects of armodafinil.
Although armodafinil can improve wakefulness in appropriately diagnosed patients, this does not establish it as a treatment for improving academic performance, intelligence or productivity in otherwise healthy individuals.
For further background, read our scientific guide to how modafinil works.
What Is Armodafinil Used For?
In the United States, licensed armodafinil medicines are indicated for excessive sleepiness associated with three conditions in adults.
Narcolepsy
Narcolepsy is a chronic neurological sleep disorder that affects the regulation of sleeping and waking.
Symptoms may include excessive daytime sleepiness, sudden sleep episodes, cataplexy, sleep paralysis and hallucinations around sleep onset or awakening.
Armodafinil may help manage excessive sleepiness but does not cure narcolepsy or address every symptom.
Obstructive Sleep Apnoea
Obstructive sleep apnoea occurs when the upper airway becomes repeatedly obstructed during sleep, interrupting normal breathing.
Under US prescribing information, armodafinil can be used to improve wakefulness in certain adults who experience residual sleepiness associated with obstructive sleep apnoea.
It does not treat the underlying airway obstruction and is not a substitute for prescribed treatments such as continuous positive airway pressure (CPAP).
Shift Work Disorder
Shift work disorder involves sleep problems associated with working hours that overlap with normal sleeping periods.
US-approved armodafinil medicines have an indication for excessive sleepiness associated with this condition.
Whether a medicine may be prescribed for a particular indication depends on the country, product authorisation and individual medical assessment.
Artvigil 150mg Dosage and Administration
150mg is a recognised armodafinil tablet strength, but it is not an appropriate dose for every patient or medical condition.
US prescribing information for Nuvigil identifies 150mg to 250mg once daily in the morning for narcolepsy and obstructive sleep apnoea, and 150mg before a work shift for shift work disorder.
Those instructions are specific to the authorised US medicine and should not automatically be applied to Artvigil or another product whose authorisation has not been established.
Important Dosage Considerations
- Use armodafinil only under appropriate medical supervision.
- Follow the prescription and product information supplied by a qualified healthcare professional.
- Do not increase the dose to compensate for inadequate sleep.
- Discuss insomnia and other adverse effects with your prescriber.
- Patients with severe liver impairment may require lower doses.
- Older adults may require additional monitoring or dose adjustments.
Dosage warning: Do not self-prescribe Artvigil 150mg or modify a prescription based on online product descriptions. Appropriate dosing depends on the diagnosis, individual patient and authorised medicine.
Possible Side Effects of Armodafinil
Armodafinil can cause unwanted effects. The severity and frequency of adverse reactions vary between individuals and may be affected by other medicines and existing health conditions.
Commonly Reported Side Effects
- Headache
- Nausea
- Dizziness
- Difficulty sleeping
- Nervousness
- Anxiety
- Digestive discomfort
Serious Adverse Reactions
Less common but potentially serious reactions include severe skin disorders, hypersensitivity reactions, psychiatric symptoms and cardiovascular problems.
Serious skin reactions, including Stevens-Johnson syndrome, have been reported with armodafinil and related medicines.
Seek urgent medical attention if you experience a severe rash, skin blistering, facial swelling, breathing difficulties, chest pain or other significant symptoms.
New or worsening psychiatric symptoms, such as hallucinations or major changes in mood or behaviour, should be discussed promptly with a healthcare professional.
Armodafinil Warnings and Precautions
Armodafinil is not appropriate for everyone. Medical assessment should include any existing health conditions, contraindications and potential interactions.
US prescribing information identifies known hypersensitivity to modafinil or armodafinil as a contraindication.
Additional precautions may be required for people with:
- Cardiovascular disease
- High blood pressure
- Heart rhythm abnormalities
- Psychiatric conditions
- A history of substance misuse
- Significant liver impairment
Always inform your healthcare professional about prescription medicines, over-the-counter products and supplements.
Artvigil 150mg and Pregnancy
Armodafinil may pose risks during pregnancy. Patients who are pregnant, planning pregnancy or who suspect they may be pregnant should seek medical advice about treatment.
Armodafinil can also reduce the effectiveness of certain hormonal contraceptives.
Armodafinil and Hormonal Contraception
US prescribing information for Nuvigil advises alternative or additional effective contraception during treatment and for one month after discontinuation.
These instructions relate to US-approved armodafinil products. Patients should seek advice relevant to their prescribed medicine and jurisdiction.
Contraception warning: Do not assume hormonal contraceptives will remain fully effective whilst taking armodafinil. Discuss appropriate contraception and the duration of protection with your healthcare professional.
Artvigil 150mg vs Modafinil
Armodafinil and modafinil are related medicines but are not chemically identical.
Modafinil contains both R- and S-enantiomers, while armodafinil contains the R-enantiomer.
These differences influence their pharmacokinetic profiles. Equal milligram amounts should not automatically be considered equivalent in clinical effects.
Neither medicine should be substituted for the other without appropriate medical advice.

However, the presence of the same declared active ingredient does not automatically establish that Artvigil has demonstrated therapeutic equivalence to Nuvigil or that it carries identical regulatory approvals.
Reliable comparisons require verified information about the manufacturer, formulation, product authorisation and pharmaceutical quality.
