Available as: 150 mg

Indications & Uses

Armodafinil is used to improve wakefulness in adult patients who have obstructive sleep apnea (OSA), narcolepsy or shift work disorder (SWD).

Pharmacology

Armodafinil is an indirect dopamine receptor agonist. It is the R-enantiomer of Modafinil, which is a 1:1 mixture of the R- and S-enantiomers. Armodafinil binds to the dopamine transporter and blocks dopamine reuptake. As a result, neuronal activity rises in the hypothalamus, and activity increases in the hypothalamic wakefulness center (TMN, tuberomammillary nucleus) within the hypothalamic sleep wake switch.

Dosage Reference

Reference Information Only

Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.

Adults:

Adults with obstructive sleep apnea or narcolepsy take Armodafinil as a single dose of 150 mg to 250 mg in the morning. For shift work disorder, the dose is 150 mg as a single dose about 1 hour before the work shift starts.

Children: safety and effectiveness have not been established in patients under 17 years of age.

Elderly: with age, the body may clear Armodafinil and its metabolites more slowly. So lower doses should be considered for older patients, and they should be monitored closely.

Side Effects

The most common side effects of Armodafinil are serious rash (including Stevens-Johnson syndrome), angioedema and anaphylaxis reactions, multi-organ hypersensitivity reactions, persistent sleepiness, psychiatric symptoms and some cardiovascular events.

Cautions & Contraindications

Warnings & Precautions

Patients taking Armodafinil should be warned not to drive or operate hazardous machinery until it is reasonably certain that the medicine won't affect their ability to do these things safely. Take care when treating anyone with a history of psychosis, depression or mania. If psychiatric symptoms develop, stopping treatment should be considered. Heart rate and blood pressure should be monitored more closely, and caution is needed when prescribing Armodafinil to patients with known cardiovascular disease.

Contraindications

Armodafinil must not be given to anyone who is known to be hypersensitive to Armodafinil or to any of the excipients in this product.

Pregnancy & Breastfeeding

There are no adequate and well controlled studies of Armodafinil in pregnant women. So it should be used during pregnancy only if the possible benefit justifies the possible risk to the fetus.

It isn't known whether Armodafinil or its metabolites pass into human milk. Many drugs do, so caution is needed when Armodafinil is given to a nursing woman.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Use in Special Populations

Patients with hepatic impairment: if a patient has severe hepatic impairment, Armoda (armodafinil) should be given at a reduced dose.

Patients with renal impairment: there isn't enough information to say whether dosing is safe and effective in patients with severe renal impairment.

Overdose

No overdoses were reported in the clinical studies of Armoda (Armodafinil). If one does happen, the symptoms are likely to be similar to those seen with Modafinil, which included excitation or agitation, insomnia, and slight or moderate rises in hemodynamic parameters. There is no specific antidote for Armoda overdose. Treatment is primary supportive care.

⚠️ In an emergency call 999 or go to the nearest hospital emergency department.
