Modafinil Provigil Over The Counter
Modafinil is a psychostimulant widely used to treat obstructive sleep apnea syndrome, narcolepsy, and work schedule shifts. The drug works by improving wakefulness and eliminating excessive sleepiness. Although modafinil is a stimulant, its effects differ from traditional stimulants such as amphetamines and cause far fewer side effects.
Mechanism of action of modafinil
Modafinil’s mechanism of action is not fully understood, but it is known to affect neurotransmitters such as dopamine, norepinephrine, and serotonin. Modafinil increases the levels of these neurotransmitters in certain areas of the brain, thereby improving wakefulness and attention.

Indications for Modafinil
Modafinil is commonly prescribed to treat the following conditions:
- Narcolepsy: a sleep disorder characterized by excessive sleepiness and sleep attacks during the day.
- Obstructive sleep apnea syndrome: a breathing disorder during sleep that causes repetitive awakenings and excessive sleepiness.
- Sleep disorder associated with work schedule shift: sleep disorder caused by asynchrony between the internal biological clock and the work schedule.
Contraindications and side effects
Although modafinil is considered a relatively safe drug, there are certain contraindications and side effects to consider:
- Allergic reactions: modafinil can cause skin reactions, which can be serious. If a rash, swelling, or itching occurs, you should stop taking the drug immediately and see a doctor.
- Heart problems: modafinil may cause palpitations or high blood pressure, especially in people with cardiovascular disease. If you have heart problems, consult your doctor before starting modafinil.
- Mental disorders: modafinil may aggravate symptoms of mental disorders such as anxiousness, depression, or bipolar disorder. If you have a history of mental illness, notify your doctor before starting the drug.

Dosage and route of administration of modafinil
Your doctor determines the dosage of modafinil and depends on the specific condition that needs to be treated. Typically, modafinil doses range from 100 mg to 200 mg daily, but individual adjustments may be necessary in some cases.
For narcolepsy and obstructive sleep apnea syndrome, a single dose is usually prescribed in the morning to provide lasting stimulation throughout the day. For sleep disorders associated with work schedule shifts, a dose of modafinil should be taken one hour before the start of the work shift.
It is important to strictly follow the doctor’s recommendations and not exceed the specified dose. Modafinil is usually taken once in the morning to reduce the likelihood of sleep disturbance. The drug can be taken with or without food.
Interaction with other drugs
Modafinil may interact with other medications, changing their effectiveness or increasing their side effects. It is important to tell your doctor about all medications you are taking, including prescription and over-the-counter medications, supplements, and herbs.
Some examples of interactions between modafinil and other drugs:
- Anticoagulants (e.g., warfarin): modafinil may increase their effects, increasing the bleeding risk.
- Oral contraceptives: modafinil may decrease effectiveness, potentially leading to unwanted pregnancy.
- Anticonvulsants (e.g., phenytoin, carbamazepine): modafinil may decrease their blood concentration, reducing their effectiveness.
- In case of unwanted effects or symptoms of overdose, consult a physician immediately.
Conclusion
Modafinil is a psychostimulant that helps manage excessive sleepiness associated with narcolepsy, obstructive sleep apnea syndrome, and sleep disorders associated with shifting work schedules. Following your doctor’s recommendations and controlling side effects, modafinil can be a useful and safe medication to improve wakefulness and quality of life. It is important to consult your doctor before starting modafinil, especially if you have cardiovascular disease or psychiatric disorders.
