What is Modafinil?

Modafinil is from the drug class of analeptics. With its help, patients can stay awake for more than 40 hours, with high activity, improved mood, and increased concentration.

Modafinil improves memory and enhances overall perception, response time, and cognitive abilities. It has a softer effect than amphetamines, allowing patients to stay awake for longer periods of time and easily fall asleep after the the drug’s effects has ended.

In the US, modafinil is sold in pharmacies under the name Provigil and is approved by the FDA. It is prescribed for patients suffering from narcolepsy, drowsiness and sleep disorders, dyspnea, and a sharp decrease in the frequency and depth of breathing.

It also does not share the side effects common to other psychostimulants (cocaine, caffeine, amphetamine), such as, for example, hand trembling.
Today, the representatives of many professions that require prolonged wakefulness take modafinil: the army, special forces, doctors, ambulance officers, police, and firefighters. Modafinil is also popular among taxi drivers, truck drivers, and even programmers.

Modafinil can be used in the following cases:

  • Narcolepsy.
  • Chronic fatigue.
  • Pathological drowsiness (hypersomnia).
  • Myotonic dystrophy.
  • Seasonal affective disorder.

Also, the medication can be prescribed to prolong patients’ psychophysical activity, increase psychomotor reactions, and relieve depression.


The doctor sets the necessary dosage for the individual patient. The dosage of Modafinil ranges from 200 to 400 mg per day. The tablet is usually accompanied by high liquid intake (preferably a large glass of water). It is desirable to take medicine in the morning so that the state of wakefulness continues throughout the day and less sleep disturbance is observed.

If a patient has hypertension, then during treatment with medication, he or she needs to monitor blood pressure.
If the patient has impaired liver function, then the dose of the drug should be reduced to 100–200 mg per day.
Patients with renal or hepatic impairment should receive a reduced dosage.


The drug should not be prescribed to the following categories of people:

  • Patients who have increased sensitivity to the drug.
  • Patients who have suffered cardiovascular diseases.
  • Patients with cirrhosis of the liver.
  • Females during pregnancy, and also during lactation.

Also, patients should be aware that modafinil reduces the effectiveness of contraceptives, which could potentially lead to unplanned pregnancy. The drug cannot be combined with alcohol. This medication can also give a positive result in doping control, which is important information for athletes.
Since this pharmaceutical agent raises the level of histamine, it is better for people prone to allergic reactions to abstain from it.

  • Nerve agitation.
  • Increased blood pressure.

In case of an overdose, the patient should immediately call an ambulance.

Modafinil has a minimal number of side effects with an impressive result, which is expressed in increased efficiency, improved concentration, and reduced need for sleep. That is why today many military departments of different countries are raising the question of the complete replacement of the traditional amphetamine with modafinil. Due to its outstanding qualities, the drug is actively used among cosmonauts, pilots, and even law enforcement officers.

For example, in some US states, police officers receive 200 mg of Modafinil daily to increase productivity and improve response time.
