How long does it take for modafinil to work?

Modafinil is a known medication that is taken by people who usually sleep excessively during the day. This is a generic medication that also works well in treating a condition known as “obtrusive sleep apnea.” It can also be used for treating excessive sleepiness caused by narcolepsy as well as various types of sleeping problems. Modafinil is ingested orally and once taken goes to work as an agent of wakefulness. Once in the body, it goes to the brain – its main site of action – and triggers certain neurotransmitters. This causes chemical changes inside the brain. The changes triggered by Modafinil in the brain cause excitement in that area to increase wakefulness.

Modafinil is classified as a stimulant since it increases the amount of glutamate and dopamine in the brain. As a mild stimulant, Modafinil is not classified as a stimulant drug. The drug will not cause the following effects that are common with stimulants:

  • The usual crash associated with taking stimulants
  • Shakes
  • Jitteriness

How long does it take for Modafinil work?

Modafinil is an effective anti-sleeping drug that causes the expected effects among various patients. However, what seems elusive is the time it takes for Modafinil to kick in after ingestion. Modafinil works similarly to every other over-the-counter medication. This means that the time needed for the drug to become fully active in humans varies from one person to the next.

Some users have reported the initial effects of the medication can be felt within 30 minutes of ingestion while the majority of Modafinil users say it takes about an hour before any effects of the drug can be felt.

Factors that affects/alter the time taken for Modafinil to start working

To understand the way Modafinil works, users need to know the primary factors that interact with or alter the way Modafinil works. Once Modafinil is taken, the time needed for users to start feeling its effects varies based on several human factors. This means that several factors affect how quickly a user can begin feeling the full effect of the drugs. These factors include:

  • The type of condition that they are treating: The specific sleep condition or disorder that is being treated for will usually affect the time it takes for the Modafinil to fully kick in.
  • General health: General health among users usually affects how soon they start feeling the earliest effects of Modafinil.
  • Age: Age is a factor that affects how soon a user begins to feel the earliest effects of Modafinil.
  • Diet: Diet among users is also a factor that determines how soon they start to feel the effects of the drug.
  • Weight: The weight of the user is also a determining factor that influences the total time needed for the drug to take its full effect. With this analogy, it means that users who are overweight will notice the drug’s effects a lot slower in comparison to healthy users.
  • Food: Food is another significant factor that affects the time taken to start feeling the full effects of Modafinil. This is so because the body will not perform various functions at the same time. If the body is busy digesting food, Modafinil will take a very long time to get to the bloodstream of the user.

Since food is among the factors that determine how soon Modafinil starts working in the body, is it advisable to take the drug while eating? Physicians have reported that the drug can cause mild irritation if taken without eating anything in the morning. This is why many users prefer to take the drug whenever they are eating in the morning. But a most recommendable way to enhance the working time of Modafinil is to take a light food before Modafinil is taken. When the drug is consumed immediately after the user has eaten a fairly large meal, Modafinil can take about 90 minutes to start showing its initial effects.

Modafinil: What to do when it takes too long to work

The way Modafinil works varies from one user to another. For some people, it can be about half an hour. While for most other people, this can be up to an hour. While some people consistently experience the delayed effects of Modafinil.

For users who experienced a delay in the action of the drug, it is recommended that they consult their doctors about increasing the dosage of the drug.

An increase in Modafinil dosage is exclusively reserved for users that have extreme sleeping problems and may not be recommended for people who simply notice that it takes longer for the drug to work. you may read best nootropics blogs here.

Specific Modafinil dosages for optimal working time

When it comes to Modafinil dosages for optimal working time, doctors usually prescribe the drugs based on several factors. These factors are:

  • The patient’s age
  • The medical records of the patient
  • The current health condition of the patient
  • The particular sleep condition that you are treating

To start, the minimum dosage of Modafinil for optimal effects is recommended as 100mg. But many patients suffering from narcolepsy and sleep apnea are recommended a dosage of 200mg. Those people with obstructive sleep apnea and daytime sleepiness are about 200mg – while 400mg is not a rare dosage but it is uncommon among patients and users of the medication. The dosage of Modafinil usually affects its working time and effects. Then again, taking a large dosage of the drug will not necessarily cause it to start working sooner. Many users who have taken dosages of between 200mg and 400mg have said that they did not notice any marked difference.

Possible interaction with other agents: Does this affect the time it takes for Modafinil to kick in?

The effects of Modafinil on the human body can be altered with the presence of other agents like beverages, food, and various other drugs. The time when the drug was taken will also play a part in affecting how soon it kicks in. For example, users who take Modafinil in a mildly sleepy state may feel the drugs kick in a lot sooner. In the same way, people who are in the middle of intense sleep may notice a delayed time for the drug to take full effect.


Modafinil is a drug that promotes wakefulness. People rely on the drug to stay awake and active when they have to. However, the time it takes for the drug’s full effect to be felt varies among users. Studies have revealed that such factors like food, weight, diet, age, general health, and the condition being treated.
