How long does it take Modafinil to wear off?

Modafinil is a nootropic which increases energy levels and alertness – specifically for those people who have a problem getting enough sleep.

Mostly, it is used as a crucial component in nootropic stacks designed to help individuals study and for other productive tasks. Modafinil users often state that this supplement gives them a bigger energy boost than other stimulants.

It is the preferred nootropic for its ability to enhance concentration. Clinically, it is prescribed for people who suffer from narcolepsy, obstructive sleep apnea and other sleep-related disorders.

Note: this article discusses the half life of Modalert 200, which I get here.

Where did Modafinil come from?

cognitionModafinil is an analeptic drug, also classified as a “smart drug” that is known to improve performance of a subject weakened by fatigue and lack of sleep.

Created in 1970 by a French medical professor Michel Jouvet, it continued to be used as an experimental treatment for narcolepsy back in 1986. Narcolepsy is a condition that can cause people to fall asleep at any time during the day.

Since then, the use of modafinil has expanded to treat other conditions, such as shift work disorder and chronic daytime sleepiness associated with obstructive sleep apnea.

For this reason, it is commonly used as a nootropic to improve cognitive performance in people who do not get enough sleep otherwise. Using Modafinil elevates locomotors activity and histamine in the central nervous system.

The effects of Modafinil are presented to wear off once the natural concentration of neuronal histamine has been depleted by a powerful inhibitor.

Side effects of Modafinil

Modafinil is considered safe, without harmful side effects when used as directed. There are some mild side effects of Modafinil you might encounter during regular use, including vomiting, dry mouth, headache, rapid weight loss and insomnia.

How long does it take for Modafinil to wear off?

Modafinil should be taken very early in the morning so that their effects can last the whole day and wear off late at night so your regular sleep cycle isn’t interrupted. However, Modafinil is processed differently for every other individual.

For some, it might last up 20 to 24 hours before wearing off (though this is rare). Yet others still have to take it twice a day to enjoy the full benefits. The supplement ideally takes 30 minute to an hour to kick in, and lasts for roughly 8-10.5 hours.

(Note: Armodafinil is a bit stronger, and takes about 10-12 hours to fully wear off).

If you use this supplement as a method to fight sleeping disorders if you work at different shifts, then consider taking the supplement at least one hour before the start of work. Most user comments say it is almost impossible to fall asleep within 12 hours of taking this smart drug, so plan your intake of the medication accordingly.

Also note: if you take Modafinil very regularly (more than 3 times a week), the residual effects seem to stay in your system for much longer than 10 hours. For example, if you took Modafinil 5 days in a row, it would take a day or two before you feel 100% “normal” again.

If you keep this up for weeks or months, it could take up to a week without Modafinil before your brain fully resets — so don’t overdo it!


The recommended dose is typically 200 mg taken once a day, usually in the morning. Some people suggest starting with a 100 mg dose for the first week so that people can become familiar with the effects. It is also possible to higher doses.

Up to 400 mg per day has been shown to be very well tolerated. However, it is also unclear whether or not the increase in dose will be additional benefits. For those who are unaware of the impact of this drug on their body, it is recommended you consult a qualified doctor before you get started.

Will It Alter Sleep Patterns?

Through extensive medical studies and hours of testing, scientists have found no problems with their subject’s ability to fall asleep after taking the drug. The reactions that occur within your brain that are enacted by the drug don’t mess with your sleep cycle after the drug has effectively kept you awake.

In short, your ability to sleep or not is all on you.


Modafinil has been shown to help people stay awake and active, as well as make their minds much clearer if their memory has been exacerbated by the onset of sleep deprivation.

Successful studies have shown a correlation between the use of this medicine and maintaining cognitive function. For a general increase in focus, concentration and short-term memory, I would recommend Modafinil.

Ensure you talk to your doctor before taking it, and take the correct dosage as prescribed. It should also be taken very early in the morning and not during the day as it may prevent you from sleeping.

When you decide to start on Modafinil, individuals should do their research and understand how to get the most out of your medication.
