What Is Modafinil? Uses and Side Effects

Sleep Disorder

Modafinil is a drug prescribed to treat narcolepsy and shift-work sleep disorder. It belongs to a class of drugs called wakefulness-promoting agents. Other drugs in this class include armodafinil and adrafinil.

Modafinil is typically prescribed to be taken once a day in the morning. It can be taken with or without food. Modafinil should be taken at most once a day. You can buy Modafinil Online from a reputed Online Pharmacy Store.


Modafinil sounds like something a mad scientist would concoct in his lab. But this “smart drug” treats various conditions, from narcolepsy to ADHD like sleep disorder.

One of the most popular uses for modafinil is as a cognitive enhancer. In other words, it helps people stay focused and motivated. This makes it a popular choice for students and professionals who want an edge in our competitive world.

Side Effects

The evidence of scientific data supports modafinil’s general safety and efficacy when taken as prescribed and under the supervision of a Doctor, given that it has received FDA clearance for a few specific medical purposes.

But just as with any medication, there is always a chance of suffering adverse side effects, so it’s critical to be aware of them. Connect with Doctor, if the following symptoms appear after taking modafinil.

  • Tachycardia
  • Agitation
  • Nausea, and
  • Anxiety is modafinil’s most frequent severe adverse effect.

Most reported adverse side effects are typically mild to moderate, with headaches, uneasiness or anxiety, sleeplessness, and nausea being the most prevalent symptoms, according to one research on the possible long-term effects of modafinil.

At therapeutic levels, modafinil did not increase average blood pressure or heart rate in people at risk for heart disease, according to the same analysis.

The FDA has reported a few occurrences of modafinil-induced Stevens-Johnson syndrome (SJS), a skin allergy.

Inadvisability of Modafinil

When administered by trained medical experts, it has a variety of well-supported medicinal applications. However, there are several things that physicians may look for that would prevent someone from being treated with modafinil (due to elevated risk of harmful side effects or other adverse reactions).

  • Cardiovascular disease: unstable angina, left-ventricular hypertrophy, uncontrolled hypertension or recent myocardial infarction.
  • Other psychiatric disorders, such as a history of mania symptoms or psychosis.
  • Tic disorders, such as Tourette’s syndrome, may be worsened by stimulants such as modafinil.
  • Liver and kidney impairments: these problems are usually treatable by treatment but generally require adjusting the dose.

Interaction with other drugs

Like many medications, modafinil can interfere with the effects of other medicines, which may result in serious health issues.

As always, the best way to reduce the risk of adverse drug interactions is to take advice to your doctor about all of your treatment options and to make sure that they are fully aware of any additional medications or dietary supplements you are taking, other underlying medical conditions, or any other potential health-related factors that may influence your treatment.

Although early investigations have shown possible adverse interactions between modafinil and the following medicines and other substances, the entire spectrum of modafinil’s potential medication interactions is still not fully understood.

  • Phenytoin
  • Cyclosporin
  • Triazolam
  • Ethinylestradiol
  • Diazepam

Additionally, some scientists think modafinil could interact with specific proteins or enzymes crucial for the disintegration and elimination (metabolism) of a wide range of other medications and substances. For instance, early research indicates that modafinil may suppress the CYP2C19 and CYP3A4 enzymes [79, 78]. As a result, when taking modafinil, any medications that the body needs to utilize those enzymes might have their effects changed or badly impacted.


Like any medicine, modafinil overuse can negatively affect a person’s health.

As long as the drug is only taken as prescribed by a doctor and is used following those directions, the risks of overdosing are negligible.

Nevertheless, at least one instance of a patient purposefully overdosing on modafinil during a suicide attempt has been documented. The dosage this patient received was relatively high (>5 grams), and they experienced some symptoms, including

  • Impaired movement (dyskinesia)
  • Moderate heart complications
  • Insomnia
  • Severe headaches

Fortunately, most of these symptoms seemed to go away after a day or so. Furthermore, the patient’s liver and kidneys appeared to have sustained minimal long-term harm.

Nevertheless, aside from this one case study, little information is available regarding the likelihood or potential symptoms of a modafinil overdose. As a result, caution is still strongly advised when using this medication, and care should always be taken only to take it as specifically prescribed and instructed by your doctor.
