What is Modaheal 100 mg?
Modaheal 100 mg is a medication that is a wakefulness-promoting agent used to manage excessive daytime sleepiness associated with:
- Narcolepsy
- Shift Worker Sleep Disorder
- Obstructive Sleep Apnea
It doesn’t cure the underlying disorder but helps manage the symptoms of excessive sleep disorders.
How does it work?
- Modafinil blocks the reuptake of Dopamine transporter (DAT), the hormone responsible for clearing dopamine out of the synaptic cleft.
- Since the DAT is inhibited, there is higher build up of dopamine in the space between the neurons.
- There is increased dopamine availability that leads to stronger stimulation of postsynaptic dopamine receptors.
- The net effect is heightened wakefulness and improved alertness

INTERACTIONS
Other medications metabolized by the same liver enzymes. Because of this enzyme-inducing effect, it can lower blood levels of drugs like:
- Certain immunosuppressants (e.g., cyclosporine)
- Some anticonvulsants
- Certain antifungals
- Some HIV medications
It can also increase levels of drugs metabolized by CYP2C19, such as:
- Certain blood thinners (e.g., warfarin)
- Some antidepressants and anticonvulsants (e.g., phenytoin)
CNS/stimulant-related interactions:
- MAOIs
- Other stimulants or wakefulness agents
- Alcohol
- Other medications affecting heart rhythm or blood pressure
Hormonal contraceptives: Modafinil induces certain liver enzymes (CYP3A4), which can reduce the effectiveness of hormonal birth control (pills, patches, rings, implants). This effect can last for about a month after stopping the medication, so a backup contraceptive method is usually recommended.
People with a history of heart problems (especially those with mitral valve prolapse, left ventricular hypertrophy, or arrhythmia), high blood pressure, liver or kidney impairment, or a history of psychiatric conditions (depression, mania, psychosis) are typically flagged as needing extra caution or closer monitoring.
