Benefits of Modvigil

Modvigil is a cognitive stimulant but unlike other drugs in the afinil family, it produces more subtle effects. The drug works through the orexin system in our brain and increases neurotransmitters like dopamine and norepinephrine.

The orexin system is responsible for regulating our sleep cycle. Dopamine, on the other hand, is associated with focus, emotion, and the reward center responsible for controlling our habits and motivations.

Modvigil helps users stay alert longer while they are studying, resulting in fewer breaks and increased productivity. Because of this, many people take it to get rid of writer’s block, cram for tests, and finish monotonous and tedious tasks more quickly.

Modvigil Dosage and Administration

Dosage in Obstructive Sleep Apnea and Narcolepsy

The recommended dosage for this drug is 200 mg taken once a day for patients who suffer from obstructive sleep apnea and narcolepsy. Two Modavil 200 mg tablets have been given as a single dose and have been well-tolerated although there is not enough evidence to suggest that the double dosage provides any additional benefits to the patient.

Dosage for Shift Work Disorder

The recommended dosage for patients with shift worker disorder is 200 mg taken orally once a day about 1 hour before their shift starts.

Dosage for Patients With Severe Hepatic Impairment

Patients who have severe hepatic impairment need to reduce their dosage of Modvigil tablets by half that recommended for patients with healthy livers.

Dosage for Geriatric Patients

Patients who are over 65 years of age need to be closely monitored if they are given a dose of Modvigil. In older patients, the elimination of the drug and its metabolites may be reduced as a natural consequence of aging. Therefore, it is recommended that their dosage be lowered and the patients be monitored.

Dosage for Expectant or Nursing Mothers

There are no well-controlled studies which can show the effect of Modvigil on the health of a pregnant or nursing mother. In some cases, intrauterine growth restrictions and spontaneous miscarriages have been linked with the use of this med. It is also unknown if the drug is passed into breast milk. Therefore pregnant and lactating women should consult their doctor first before using Modvigil.

Dosage for Pediatric Patients

Modvigil has not been established as safe and effective for this population. Adverse reactions like serious skin rash, including Stevens-Johnson Syndrome (SJS) and erythema multiforme major (EMM), have been linked with the use of Modvigil in the younger population.  Hence, infants and children should not be administered this drug.

Modvigil Interactions with Other Drugs

Effects of Modvigil on CYP3A4/5 Substrates

There are many drugs that may be deactivated or exhibit reduced clearance by Modvigil, including CYP3A4/5 Substrates, resulting in reduced systemic exposure. Adjustment of dosage of these drugs should be considered if they are taken in conjunction with Modvigil.

Additionally, the efficacy of steroidal contraceptives may be reduced while the patient is taking Modvigil and will remain so till one month after discontinuing Modvigil. Alternative methods of contraception are recommended for patients who have been taking steroidal contraceptives.

Blood levels of immunosuppresant medication like cyclosporine may be reduced when used in concomitantly with Modvigil tablets. Adjustment of dosage is recommended in this case.

Effects of Modvigil tablets on CYP2C19 Substrates

Conversely, there are many drugs that may show prolonged elimination when used with Modvigil due to the inhibition of metabolic enzymes. This results in higher systemic exposures. Therefore, levels of drugs containing  CYP2C19 substrates like selective serotonin reuptake inhibitors and tricyclic antidepressants, may be increased if taken in conjunction with Modvigil. Reducing the dosage for these drugs may be necessary for such drugs.

Effects of Warfarin

When taking blood-thinning medicines like Warfarin in conjunction with this med, the prothrombin time (a test used to detect bleeding or clotting disorders) and INR (international normalized ratio) must be considered.

Effects of Monoamine Oxidase Inhibitors

Taking Modvigil with MAOIs can lead adverse effects like chest pain, high blood pressure, severe headaches, and high body temperature. People who take Modvigil should not take MAOI within 14 days of using the drug.



Clinical trials show that patients who have been given 5 to 8 times the recommended dosage of Modvigil 200 mg have not experienced any unexpected or life-threatening effects. However, there were many side effects reports including agitation and excitation, insomnia, aggressiveness, confusion, tremors, nausea, diarrhea, sleep disturbance, and moderate elevations in hemodynamic parameters.

No specific antidote exists for this med and patients who overdose on this drug should be closely monitored, especially their cardiovascular behavior.

Where to Buy Modvigil

This drug has been classified as a IV controlled substance in the United States and Australia since it offers medicinal benefits, but with potential for abuse.

Because of the ambiguous legal status of Modvigil, the drug cannot be bought in stores based outside of the United States, Canada, Europe, and Australia. However, you can buy Modvigil from online vendors in India since the country doesn’t classify Modvigil as a prescription drugs.
