What is Modafinil?
Modafinil is a medication that is used to promote wakefulness and alertness. It belongs to a class of drugs called eugeroics, which means “good arousal” in Greek. Modafinil was first approved by the US Food and Drug Administration (FDA) in 1998 for the treatment of narcolepsy, a sleep disorder that causes excessive daytime sleepiness and sudden sleep attacks.
Since its approval, modafinil has been prescribed for other sleep disorders such as obstructive sleep apnea and shift work sleep disorder, and has also been used off-label for various purposes. Modafinil is believed to work by increasing the levels of certain neurotransmitters in the brain that regulate wakefulness, such as dopamine, norepinephrine, and histamine.
Modafinil is available in tablet form and is typically taken orally, with or without food. It is usually taken in the morning, as taking it later in the day can interfere with sleep. The dosage and duration of treatment depend on the specific condition being treated, as well as individual factors such as age, weight, and overall health.
While modafinil is generally considered safe and effective when used as directed, it can cause side effects such as headache, nausea, and insomnia. It is important to talk to a healthcare provider before taking modafinil to discuss any potential risks and benefits, and to determine the appropriate dosage for your specific needs.
Factors Affecting Modafinil Dosage
Several factors can affect the appropriate modafinil dosage for an individual. These factors include:
- Age: Older adults may require a lower dosage of modafinil due to age-related changes in liver and kidney function, which can affect how the drug is metabolized and eliminated from the body.
- Weight: The dosage of modafinil may be adjusted based on a person’s weight, as higher body weight may require a higher dosage to achieve the desired effect.
- Health status: Individuals with liver or kidney disease may require a lower dosage of modafinil due to reduced clearance of the drug from the body. Similarly, individuals with heart disease or high blood pressure may need to be monitored closely when taking modafinil, as the drug can increase heart rate and blood pressure.
- Concurrent medications: Modafinil can interact with other medications, including hormonal contraceptives and anticoagulants. It is important to inform a healthcare provider of all medications and supplements being taken to avoid potentially harmful interactions.
- Purpose of use: The recommended dosage of modafinil can vary depending on the intended use. For example, the dosage for narcolepsy may be higher than that for cognitive enhancement or weight loss.
It is important to consult with a healthcare provider to determine the appropriate modafinil dosage based on these and other individual factors. Taking too high of a dosage can increase the risk of side effects, while taking too low of a dosage may not provide the desired benefits.

It is important to take modafinil at the same time each day to maintain consistent levels in the body.
