What is Modafinil?


Modafinil is a U.S. FDA approved wakefulness and alertness promoting drug, widely used in the treatment of narcolepsy, obstructive sleep apnea/hypopnea syndrome (OSAHS), and shift work sleep disorder (SWSD). Modafinil is also showing promise in the treatment of depression and attention-deficit/hyperactivity disorder (ADHD). Most recently, it has drawn a lot of attention for its off-label use as a nootropic, aka “smart drug”, for improving cognition and productivity.

Modafinil goes by many names and is commonly marketed as: Provigil, Alertec, Modavigil, Modiodal, Modalert, Alertec, BravaMax, Carim, Provake, Modalert, Modapro, Modafil, Modvigil, Modatec, Modasomil, Modavigil, Modiodal, Modiwake, Resotyl, Mentix, Alertex, Zalux, Stavigile, Vigia, Vigicer, and Vigil.

In the U.S., the Drug Enforcement Administration (DEA) categorizes modafinil as a Schedule IV drug and hence it is a controlled substance. Although Schedule IV drugs are considered to have low potential for abuse and low risk of dependence (compare to adderall which is Schedule II due to its potential for abuse and habit formation), controlled substances cannot be purchased without a valid prescription from a licensed physician.

Modafinil Benefits

Modafinil is THE most effective drug treatment for narcolepsy till date. We cover this topic extensively in our ultimate guide to narcolepsy and modafinil. However, what excites us more is that everyone in the nootropics community seems to agree that modafinil has reached legendary status in the realm of smart drugs. Moda is quickly becoming the go-to nootropic for many software engineers in Silicon Valley, finance executives on Wall Street, and high performing students at top universities.

A simple search on PubMed easily reveals that modafinil has been shown to be extremely effective in improving cognitive function, memory, alertness, attention, mood and even depression. But, how robust are these effects? Depends on who you ask. A casual user on reddit may extol modafinil as the shortcut to becoming the next Einstein, but according to a peer-reviewed scientific journal article published by top researchers at Oxford University and Harvard Medical School, modafinil is certainly an effective cognitive enhancer – but not in ways one may initially think. We cover the results of this paper in detail in our modafinil benefits article. For now, we leave you with a graph which shows the relative benefits of modafinil on various important mental dimensions:

Modafinil and Narcolepsy

People suffering from narcolepsy have disrupted sleep cycles which results in poor quality of sleep, often accompanied by excessive jerking, talking, and even frequent wake ups during sleep. Narcolepsy can also cause a condition called “cataplexy”, which is defined as a sudden loss of muscle tone or sudden experience of muscle weakness when one is awake. And to make matters worse, narcolepsy can only be managed and not cured. Hence, it is a big deal when the American Academy of Sleep Medicine notes that modafinil is one of two most effective prescription drugs for narcolepsy, the other being sodium oxybate (Xyrem).

modafinil and narcolepsy

Narcolepsy is believed to be caused by a lack of the neurotransmitter hypocretin (orexin) in the brain. Although the exact mechanisms are unknown, modafinil appears to work on the orexin/hypocretin neurotransmitter system in the brain. Neurons that respond to orexin can be found in the hypothalamus and they project beyond this area to other areas of the brain. When these neurons are activated, they increase dopamine and norepinephrine in those other areas of the brain, which are believed to one source of its cognitive enhancing and wakefulness enhancing effects. Modafinil may also reduce GABA in the brain, another neurotransmitter that promotes sleepiness. It also promotes the production of histamine in the brain. If you think about this, anti-histamines are known for producing a sleep-promoting effect, so it is not hard to see that a histamine promoting drug may enhance wakefulness.

Narcolepsy Resources

In addition to our Ultimate Guide to Narcolepsy and Modafinil, there are plenty of resources which provide support for narcolepsy patients. Here are 3 resources you should check out:

  • Narcolepsy Network

    Nonprofit organization providing unprecedented service to the narcolepsy community since 1986. Their information is well organized, and you will find educational information as well as contact information of resources local to your area.

  • Wake Up Narcolepsy

    Nonprofit organization which focuses on narcolepsy research funding and awareness. They try to unite the public, educators, and the medical community.

Modafinil and ADHD/ADD

Modafinil’s potential as a treatment for Attention Deficit Hyperactivity Disorder (ADHD) looks promising. Primarily prescribed for promoting wakefulness in narcolepsy patients, modafinil has now caught the attention of doctors since research shows that modafinil can increase focus and decision making skills, while reducing habit forming and other side effect risks usually associated with the current pharmaceutical treatments for ADHD such as amphatemine (adderall) and methyphenidate (ritalin) based drugs.

Modafinil and Weight Loss

Weight loss pills have a notorious reputation and with good reason. Doctors are hesitant to prescribe weight loss pills given the history of fatalities including the very famous Fen-Phen disaster. We live in a society which is obsessed with looking lean, yet the quality of food being consumed is not necessarily improving. A large portion of the population is either over-weight or obese. Hence, it is natural that the research community is always on the lookout for a weight loss pill which can be effective while reducing potential side-effects. Although modafinil is not prescribed for weight loss, the users of modafinil in the smart drug community have often reported robust weight loss effects with modafinil use. Naturally, we were curious and felt obligated to prepare for you an in-depth article on modafinil and weight loss.

Modafinil Mechanisms of Action

Modafinil exhibits robust effects on multiple neurotransmitters in the brain including catecholamines (norepinephrine, dopamine), serotonin, glutamate, gamma amino-butyric acid, orexin, and histamine. Not unlike many other drugs, the exact mechanisms of action for modafinil are currently unknown and is the subject of intense research. If you are of a scientific bent of mind, feel free to check out this paper on modafinil’s neurochemical actions and effects on cognition.

Adderall vs Modafinil vs Ritalin

 Adderall (amphetamine)Provigil (Modafinil)Ritalin (Methylphenidate)
MechanismCatecholamine releasing agent, weak reuptake inhibitor of dopamine (Ki = 100nM), norepinephrine (Ki = 40-50 nM), and to a lesser extent serotonin (Ki = 1.4-3.8 uM), vesicular monoamine transporter 2 (VMAT2) inhibitor, weak Monoamine Oxidase (MAO) inhibitorWeakly inhibits the dopamine transporter (DAT), norepinephrine transporter (NET), enhances histamine and orexin release, increases the glutamate/GABA ratio in hypothalamic regions and other brain regions.Methylphenidate's mechanism inhibits catecholamine reuptake, primarily as a dopamine reuptake inhibitor. Methylphenidate blocking the dopamine transporter and norepinephrine transporter, leading to increased concentrations of dopamine and norepinephrine within the synaptic cleft.
IndicationsADHD, narcolepsy, obesity, depressionExcessive daytime sleepiness caused by narcolepsy, shift work sleep disorder, or obstructive sleep apnea; ADHD (off-label), disorders of fatigue (e.g., fibromyalgia)

Modafinil Side Effects

We will not take names, but there are some prominent figures who are touting modafinil as a limitless drug with no side effects. Not only is this wrong, but it is dangerous to assume modafinil has no side effects.

Almost all drugs can have side effects and modafinil is no different. Please exercise caution and consult a physician before using modafinil. The most commonly reported side effects include headaches, nausea, diarrhea, nervousness, anxiety, dyspepsia, skin rash, and insomnia.

Any of the following modafinil side effects should be taken seriously and reported to your doctor:

• Skin rash, hives, sores in your mouth or your skin blisters and peels

• Swelling of your face, eyes, lips, tongue, or throat

• Trouble swallowing or breathing

• Fever, shortness of breath, swelling of the legs, yellowing of the skin or whites of the eyes, or dark urine.

We provide more extensive details in our in-depth article on modafinil side effects, but please consult with your physician before modafinil use.
