The main purpose of modafinil 100mg is to increase wakefulness in people who suffer from narcolepsy, shift work sleep disorder, and obstructive sleep apnea.

In general, modafinil 100 mg is used mostly for:
Narcolepsy treatment
This drug helps people who suffer from narcolepsy control their excessive daytime tiredness and improves their capacity to stay focused and alert throughout the day.
Treatment for obstructive sleep apnea
It might assist those patients who experience difficulty falling asleep at night but remain awake during the day.
Sleep disturbances related to shift work
Modafinil 100mg may be offered to people who work unconventional hours, as it helps them to stay awake and be attentive during their shifts.
It is also prescribed off-label for other purposes; some research suggests that it may also be beneficial in treating symptoms of depression, bipolar disorder, and attention deficit hyperactivity disorder (ADHD) but it needs a doctors suggestion.
Enhancing Cognitive Function
This medication is used off-label to improve cognitive abilities such as mental focus, information retention, and higher-level decision-making skills
Treatment of Attention Deficit Hyperactivity Disorder (ADHD)
Some healthcare providers may prescribe modafinil off-label to manage symptoms of ADHD, particularly in cases where traditional stimulant medications are ineffective or not tolerated.
Fatigue Associated with Multiple Sclerosis (MS):
Modafinil might be prescribed off-label to alleviate fatigue in individuals with multiple sclerosis, as it can help improve wakefulness and energy levels.

How does Modafinil 100mg Tablet Work?
The way that a modafinil 200mg tablet functions is by interfering with some brain chemicals, specifically histamine, norepinephrine, and dopamine.
The precise mode of action is yet unclear but modafinil increases wakefulness and promotes alertness by modifying the activity of certain neurotransmitters.
Dopamine
Dopamine is a neurotransmitter linked to motivation, wakefulness, and attention that is released more when modafinil is taken.
This drug decreases fatigue and increases wakefulness as it increases dopamine activity in specific brain areas.
Norepinephrine
Modafinil 100mg also modifies the brain’s norepinephrine levels. Norepinephrine is thought to be responsible as it controls arousal, focus, and stress reactions.
Due to these effects on norepinephrine, it helps patients stay awake during periods of wakefulness and promotes wakefulness.
Histamine
Modafinil affects the histamine system in the brain, which promotes wakefulness and maintains alertness.
It supports wakefulness and maintains cognitive function throughout the awake hours through the regulation of histamine activity.
Orexin/Hypocretin
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.

Precautions & Warnings:

Interactions:
CYP3A4 Inducers/Inhibitors Interactions:
The main enzyme that breaks down modafinil is cytochrome P450 enzyme CYP3A4.
Medication that raises or lowers CYP3A4 activity may change the way modafinil is broken down, which could affect how well it works or lead to unwanted side effects.
Two such examples are the inducer rifampin and the inhibitor ketoconazole.
Contraceptives with hormones:
Hormonal birth control pills, patches, and rings may not work as well when consumed with modafinil because it speeds up the metabolism of some enzymes that break down drugs.
You should think about other birth control methods that do not use hormones while you are on modafinil and for at least one month after you stop taking it.
Warfarin:
Researchers have found that modafinil may change how the blood thinner warfarin is broken down, which could make the drug less effective.
Watch the international normalized ratio (INR) values very carefully when giving warfarin and modafinil together.
Coffee:
Modafinil and caffeine both activate the central nervous system. Combining them may make you more likely to feel nervous, anxious, or have heart palpitations. Be careful if you take modafinil with medicines that contain caffeine.
Psychiatric Drug Products:
Certain drugs, like selective serotonin reuptake inhibitors (SSRIs) and monoamine oxidase inhibitors (MAOIs), may not work well with modafinil.
Taking these drugs with modafinil may raise the risk of serotonin syndrome and other bad effects.
