Those experiencing narcolepsy, a neurological disease marked by uncontrollably high levels of daytime tiredness, abrupt loss of muscular tone (cataplexy), and irregular sleep patterns at night, are frequently prescribed modafinil 200mg. Modafinil lessens the frequency and intensity of sleep attacks in narcoleptics by helping them remain awake and aware during the day.

Obstructive Sleep Apnea (OSA)

Those with obstructive sleep apnea, a condition characterised by recurrent episodes of complete or partial obstruction of the upper respiratory tract during sleep, may benefit from modafinil 200mg as an adjunctive therapy. This condition results in daytime tiredness and impaired cognitive function. For those with OSA, modafinil can increase wakefulness and decrease daytime sleepiness.

Shift Work Sleep Disorder (SWSD)

How do I Take Modafinil 200mg Tablets?

Administer Modafinil orally, as oral administration is the easiest route. Take it exactly as the physician has prescribed; don’t take more or less of it.

The patient can take modafinil with or without food. Take a glass of water and swallow the tablet whole.  To keep the body’s dosage of modafinil constant, take it at the same time every day. Since alcohol might worsen the judgement and raise the chance of adverse effects, avoid drinking while taking modafinil. Recognise the effects of modafinil on the body.

How does The Modafinil 200mg Tablet Work?

Modafinil 200mg tablet is a wakefulness enhancing medicine used in people with drowsiness due to narcolepsy or obstructive sleep apnea & daytime sleepiness due to shift work sleep disorder. The way that a Modafinil 200mg tablet functions is by interfering with some brain chemicals, specifically histamine, norepinephrine, and dopamine. It is thought that modafinil increases wakefulness and promotes alertness by modifying the activity of certain neurotransmitters, though the precise mode of action is yet unclear.


Dopamine is a neurotransmitter linked to motivation, wakefulness, and attention that is released more when modafinil is taken. Modafinil decreases fatigue and increases wakefulness by increasing dopamine activity in specific brain areas.


Modafinil also modifies the brain’s norepinephrine levels. The regulation of arousal, attention to detail, and stress response is attributed to norepinephrine. Due to its effects on norepinephrine, modafinil helps patients stay awake during periods of wakefulness and promotes wakefulness.


Modafinil affects the brain’s histamine system, which is crucial for promoting wakefulness and sustaining alertness. Modafinil supports wakefulness and maintains cognitive function throughout the awake hours by regulating histamine activity.


Orexin, sometimes referred to as hypocretin, is a neuropeptide that controls arousal, hunger, and alertness. Although the precise relationship between modafinil and wakefulness-promoting effects is unclear, it may be due to its effects on the orexin and hypocretin systems.

What are The Side Effects of Modafinil 200mg Tablets?

Some common side effects are;





Gastrointestinal problems


Mouth dryness

Appetite suppression

Back pain

Precautions and Warnings:

There are a few things to think about and cautions to take into account before taking Modafinil 200mg.


Let the physician know if the patient has any allergies to any other drugs or modafinil. It’s possible that the inactive components in modafinil pills cause allergic reactions or other issues.

Medical History

Talk to a medical practitioner about past medical history, particularly if it includes any history of high blood pressure, heart issues, mental health conditions (such as psychosis, depression, or anxiety), substance abuse, liver or kidney issues, or alcohol or drug addiction.

Pregnancy and Breastfeeding

Since the safety of modafinil during pregnancy is not fully proven, let the healthcare professional know if the patient is or plans to become pregnant. Furthermore, it is unknown if modafinil enters breast milk; therefore, before nursing while taking modafinil, speak with a medical practitioner.

Drug and alcohol use

Refrain from using illegal drugs and alcohol while taking modafinil since these actions may raise the risk of side effects and impair one’s judgement and coordination.

Mental effects

Anxiety, agitation, hallucinations, depression, suicidal thoughts, and violent behaviour are among the mental side effects that modafinil may induce. Get in touch with the healthcare provider right away if the patient notices any changes in their behaviour or mood.

Skin responses

The use of modafinil has been linked to serious skin responses, such as Stevens-Johnson syndrome and toxic epidermal necrolysis. If a patient experiences a rash, blisters, or peeling skin, stop taking modafinil and visit a healthcare provider.


CYP3A4 Inducers/Inhibitors

The cytochrome P450 enzyme CYP3A4 is principally responsible for the metabolism of modafinil. Modafinil’s metabolism may be impacted by medications that increase or decrease CYP3A4 activity, which may change the medication’s effectiveness or have unfavourable side effects. Examples are the inhibitor ketoconazole and the inducer rifampin.

Hormonal Contraceptives

Modafinil induces some enzymes involved in drug metabolism, which may lessen the efficacy of hormonal contraceptives (birth prevention pills, patches, and rings). While taking modafinil and for a month or more after stopping the medication, other non-hormonal forms of birth control should be taken into consideration.


It has been noted that modafinil may impact the metabolism of the blood thinner warfarin, hence reducing its efficacy. It is advised to closely monitor international normalised ratio (INR) values when co-administering warfarin and modafinil.


Both caffeine and modafinil stimulate the central nervous system. When combined, there may be a greater chance of jitters, anxiety, and palpitations. When taking modafinil along with drugs that contain caffeine, proceed with caution.

Psychiatric Medications

Monoamine oxidase inhibitors (MAOIs) and selective serotonin reuptake inhibitors (SSRIs) are two examples of drugs that may interact with modafinil. Serotonin syndrome and other side effects may become more likely when modafinil is taken with these drugs.


Q. What are the typical side effects of Modafinil 200mg?

Modafinil frequently causes headaches, nausea, anxiety, vertigo, sleeplessness, and dry mouth as adverse effects. Although they are uncommon, serious side effects can include allergic reactions, chest discomfort, and psychological issues. 

Q. How does Modafinil 200mg work?

Modafinil’s precise mode of action is not entirely understood. However, it is believed to have an impact on a number of neurotransmitters in the brain, including dopamine, norepinephrine, and histamine. These outcomes support increased attentiveness and wakefulness.

Q. How do I take 200 mg of modafinil?
