Artvigil 250mg Tablets (Armodafinil)

Artvigil 150mg Tablets (Armodafinil): Wakefulness & Alertness UK Guide

Artvigil 250mg Tablets contain 250mg of armodafinil as the active ingredient. Armodafinil is a wakefulness-promoting agent related to modafinil and is the R-enantiomer of modafinil. Artvigil is not a UK-licensed medicine, so it should not be presented as having a UK marketing authorisation or as a standard UK prescription product. The MHRA has identified armodafinil among unlicensed medicines used in the treatment of narcolepsy.

Armodafinil is used in some countries to improve wakefulness in adults with excessive daytime sleepiness associated with conditions including narcolepsy, obstructive sleep apnoea and shift work sleep disorder. However, these are not UK-authorised indications for Artvigil. In the UK, unlicensed medicines may only be supplied in appropriate circumstances under the relevant prescribing and importing arrangements, and unlicensed medicines have not been assessed by the MHRA in the same way as licensed medicines.

What Is Artvigil 250mg Used For?

• Wakefulness Promotion: Armodafinil is a centrally acting wakefulness-promoting agent intended to improve wakefulness and reduce excessive daytime sleepiness.
• Narcolepsy: Armodafinil is used in some countries to treat excessive daytime sleepiness associated with narcolepsy. In the UK, armodafinil products such as Artvigil are not licensed medicines.
• Obstructive Sleep Apnoea: Armodafinil has been used in some countries for residual excessive daytime sleepiness associated with obstructive sleep apnoea despite appropriate treatment. It should not replace primary treatment such as CPAP. This is not a UK-authorised indication for Artvigil.
• Shift Work Sleep Disorder: Armodafinil has also been used in some countries for excessive sleepiness associated with shift work sleep disorder. This is not a UK-authorised indication for Artvigil.
• Unlicensed Medicine Status: Artvigil should not be confused with licensed UK modafinil products. UK prescribing and supply of an unlicensed medicine requires appropriate clinical justification and must follow the applicable UK requirements.

How Does Artvigil 250mg Work?

Armodafinil is the R-enantiomer of modafinil and acts on the central nervous system to promote wakefulness. Its precise mechanism is not completely understood, but its effects involve pathways associated with dopamine and the regulation of wakefulness. By promoting wakefulness, armodafinil can help reduce excessive daytime sleepiness in people with appropriately diagnosed sleep disorders. It does not cure an underlying sleep disorder and should not be used as a substitute for sufficient sleep.

How to Take Artvigil 250mg

Follow Medical Advice: Because Artvigil is an unlicensed armodafinil product in the UK, it should only be used when prescribed or supplied under appropriate medical supervision and according to the instructions provided by the responsible healthcare professional. Usual International Dosing: In countries where armodafinil is licensed, 250mg once daily is a commonly used dose for adults with narcolepsy or obstructive sleep apnoea, while 250mg taken approximately one hour before a work shift is used for shift work sleep disorder. These dosing recommendations should not be interpreted as UK-authorised dosing for Artvigil.

• Administration: Armodafinil tablets are generally taken orally and swallowed with water. Follow the specific instructions supplied with the prescribed product.
• Timing: Taking a wakefulness-promoting medication too late in the day may interfere with nighttime sleep. The appropriate timing depends on the condition being treated and the prescribing instructions.
• Dose Changes: Do not increase, decrease or repeat the dose independently. Any adjustment should be made by the healthcare professional responsible for treatment.
• Treatment Review: Continued treatment should be reviewed regularly to assess effectiveness, adverse effects and whether ongoing use remains appropriate.

Artvigil 250mg Side Effects

Like other wakefulness-promoting medication, armodafinil can cause side effects. Report persistent or troublesome symptoms to a healthcare professional, particularly if they affect sleep, mood, blood pressure or heart function.

• Nausea
• Anxiety
• Headache
• Insomnia
• Dizziness
• Dry mouth
• Diarrhoea
• Indigestion
• Palpitations
• Reduced appetite

Serious reactions can occur with armodafinil, including severe skin reactions and psychiatric symptoms. Seek urgent medical attention if a serious rash, blistering, swelling, difficulty breathing, hallucinations, severe agitation or significant changes in mood or behaviour develop.

Important Warnings and Precautions

• UK Licensing Status: Artvigil is not a UK-licensed medicine. Unlicensed medicines do not have a UK marketing authorisation and may not have been assessed by the MHRA for safety, effectiveness and manufacturing quality in the same way as licensed medicines.
• Sleep Disorder Diagnosis: Excessive daytime sleepiness should be properly investigated because conditions such as sleep apnoea, epilepsy, depression and thyroid disorders can produce similar symptoms.
• Serious Skin Reactions: Stop treatment and seek urgent medical attention if a serious rash develops, particularly if it is associated with blistering, peeling skin, mouth sores, fever or other systemic symptoms.
• Heart and Blood Pressure: Tell your healthcare professional about high blood pressure, heart disease, palpitations or other cardiovascular problems before treatment.
• Mental Health: Tell your healthcare professional about a history of depression, anxiety, psychosis, mania or other psychiatric conditions. New or worsening psychiatric symptoms should be reported promptly.
• Other Medicines: Armodafinil can affect the way other medicines are processed by the body. Tell your doctor or pharmacist about all medication, supplements and hormonal contraceptives you use.
• Hormonal Contraception: Armodafinil may reduce the effectiveness of hormonal contraceptives through effects on drug metabolism. Discuss appropriate contraception with a healthcare professional before treatment.
• Liver and Kidney Problems: Tell your healthcare professional if you have liver or kidney problems because treatment may require additional assessment or dose adjustment.
• Driving and Alertness: Although armodafinil is intended to improve wakefulness, it may not completely eliminate excessive daytime sleepiness. Do not drive or operate machinery unless you are confident that your alertness is adequately controlled.

Stopping Artvigil Treatment

Do not change or stop armodafinil treatment without discussing it with the healthcare professional responsible for your care. The need for continued wakefulness-promoting treatment should be reviewed regularly, particularly when treating a long-term sleep disorder.

Frequently Asked Questions

What is Artvigil 250mg used for?

Artvigil contains armodafinil, a wakefulness-promoting agent used in some countries for excessive daytime sleepiness associated with conditions such as narcolepsy, obstructive sleep apnoea and shift work sleep disorder. Artvigil itself is not a UK-licensed medicine, so these should not be described as UK-authorised indications.

Is Artvigil 250mg licensed in the UK?

No. Artvigil is not a UK-licensed medicine. The MHRA identifies armodafinil among unlicensed medicines, and UK rules allow certain unlicensed medicines to be supplied only in appropriate clinical circumstances.

Is 250mg of Armodafinil a standard dose?

In countries where armodafinil is licensed, 250mg once daily is a commonly used dose for certain approved sleep-related conditions. However, this does not make 250mg a UK-authorised Artvigil dose, and treatment should only follow the instructions of the responsible healthcare professional.

Can Artvigil replace treatment for sleep apnoea?

No. Where armodafinil is used internationally for residual sleepiness associated with obstructive sleep apnoea, it is used alongside appropriate treatment of the underlying condition rather than replacing it. Treatment of the underlying sleep disorder remains important.

Can Artvigil affect hormonal contraception?

Yes. Armodafinil may reduce the effectiveness of hormonal contraception. Anyone taking hormonal contraceptives should discuss alternative or additional contraception with a healthcare professional before using armodafinil.

Is Artvigil the same as Modafinil?

No. Armodafinil is the R-enantiomer of modafinil, so the substances are closely related but are not identical. UK licensed modafinil products are available in 100mg and 200mg strengths, whereas Artvigil is an armodafinil product and is not UK licensed.
