Armodafinil in the treatment of Narcolepsy

Last updated on 11 May, 2024

Armodafinil for Narcolepsy helps in managing Excessive daytime sleepiness by secreting wake-promoting hormones, including histamine and norepinephrine. Its medical use is approved by the FDA, and works within 30 minutes of intake.

Armodafinil is a medication that belongs to the Eugeroic group (a group that promotes wakefulness) and helps in treating the symptoms of Excessive Daytime Sleepiness associated with narcolepsy, obstructive sleep apnea, and shift work disorder. However, each of these conditions varies from one another in their origin and impact on the individual. So, this blog solely concentrates on discussing Narcolepsy and its possible treatment options with Armodafinil tablets. 

Armodafinil: An Overview

Armodafinil is the R-enantiomer of Modafinil. It is a nootropic that helps in the treatment of excessive daytime sleepiness associated with narcolepsy, obstructive sleep apnea, and shift work disorder. 

 and is currently sold under different brand names like Nuvigil, Waklert, and Artvigil. 

Narcolepsy And Its Symptoms 

It is a chronic neurological disorder that causes excessive daytime drowsiness and makes people very drowsy during the day. The conditions affect the brain’s ability to control sleep-wake cycles. 

Narcolepsy can occur to anyone and at any age. However, its onset of occurrence is more commonly seen in adolescents, children, and young adults.

Some of the common symptoms of Narcolepsy, as shown in the image below, are-


  • Cataplexy or bouts of muscle weakness

  • Brain fog

  • Disrupted Night time sleep

  • Hallucination

  • Sleep paralysis.

Narcolepsy is generally caused by a chemical deficiency in the brain that helps neurons talk to each other.

Armodafinil For Narcolepsy

The clinical use of Armodafinil includes managing excessive daytime sleepiness associated with Narcolepsy, which is further shown in a 2006 study made by John R. Harsh et al. The study suggests that Armodafinil significantly improves the ability to sustain wakefulness throughout the day in patients with Narcolepsy.

Another study by JeD Black stated that Armodafinil remained effective in increasing the blood pressure of patients and is a long-term effective treatment for obstructive sleep apnea, narcolepsy, and shift work disorder. 

After the evaluation of the studies, you might be interested in adding Armodafinil to your list. You can get Armodafinil 150 mg for Narcolepsy from Healthmatter, a trusted online pharmacy, at affordable prices and discounts. 

How Does Armodafinil Treat Narcolepsy?


Armodafinil helps treat narcolepsy by increasing the level of neurotransmitters like dopamine, histamine, orexin, and serotonin. This helps in decreasing the level of GABA, which results in reduced sleepiness, and also helps in the activation of the mind and body, removing excessive fatigue. 

It is, however, essential to note that Armodafinil is not a treatment for improving Narcolepsy but only helps in managing EDS associated with the condition. 

How Long Does Armodafinil Take To Work For Narcolepsy?

Armodafinil takes 30 minutes to start working after administration. 

The half-life of Armodafinil is 12–15 hours, which is defined as the duration of time that the body requires to reduce the medicine by half. Therefore, the effects of Armodafinil for Narcolepsy last for about 12 to 15  hours. However, a medication requires 4-5 half-lives to be completely removed from the system; thus, Armodafinil stays in the system for a total of 60 to 75 hours

Armodafinil Dosage For Narcolepsy 

Armodafinil dosage might vary from patient to patient depending upon certain factors, like age and health conditions (kidney or liver dysfunction). The standard recommended dosage of Armodafinil is 150mg/day for adults above 17 years of age. 

The dosage should be taken early in the morning in order to avoid insomnia. 


  •  In any circumstance, if you miss a dose of Armodafinil, you can skip the missed dose and follow your normal dosage schedule. 

  • Do not overlap the doses; it might lead to an overdose.

Manage Narcolepsy Symptoms At Home: Natural Ways To Stay Awake 

The four basic tips to manage the symptoms of narcolepsy at home are are listed below:

Eat healthy- 

People suffering from Narcolepsy with cataplexy often are low on a hormone called hypocretin that helps them stay awake and alert. This can be improved by taking food rich in hypocretin, such as dark leafy greens,  sourdough bread, salmon, and kimchi. 

Stay Active-

Exercising and walking around for even 20 minutes can help you stay active and alert. People with desk jobs can get up and walk around in their workspace or go to the washroom to freshen up. Climbing stairs also helps. 

Get Enough Sunshine-

Sun rays are very important to help you stay awake and synthesize vitamin D in the body, which is a key nutrient in treating Narcolepsy. A low level of Vitamin D is often linked with poor-quality sleep. 

Take Naps-

You can try “strategic napping" by taking numerous naps of 15 to 20 minutes every day. But ensure not to take a nap over 30 minutes as a long sleep during the day can make you more tired.
