Modafinil Dosage Guide
Modafinil is a nootropic that improves cognitive performance. It’s particularly popular among students and white-collar workers who need to focus on difficult tasks.
When a doctor gives you Modafinil, they will give you precise instructions on how to take it and how much modafinil dosage you will take.
However, purchasers of Modafinil who buy it online are frequently perplexed about the finest dose for their prescription.
Today, we’ll examine the typical dosages for the most popular modafinil supplements, including Modafinil XL.
We’ll go through how much you should take based on your goals for taking it, including a basic dosage plan to get the most out of your medicines.
Types of Modafinil
Before we start, let’s briefly go over the different types of Modafinil.
The most common type is the original product, called Modafinil.
It’s a racemic mix of two compounds: S-Modafinil and R-Modafinil.
R-Modafinil is the more potent enantiomer, while S-Modafinil is less so.
If you see a supplement called “modafinil,” it’s almost certainly referring to the racemic mix.
There are also two pure versions of Modafinil:
- Armodafinil (Nuvigil)
- Modafinil (Provigil)
Armodafinil is the R-enantiomer of Modafinil, while Modafinil is the S-enantiomer.
So Armodafinil is more potent, while Modafinil is less so.
The two versions also have different half-lives, with Armodafinil lasting about 15 hours and Modafinil lasting 12 hours.
For this article, we’ll mostly be talking about the racemic mix of Modafinil, as it’s by far the most popular form.
The other versions are similar enough that the information here will still apply.
What’s the Best Modafinil Dosage?
The short answer is that the best dosage of Modafinil depends on why you’re taking it.
If you’re taking it for narcolepsy, sleep apnea, or shift work sleep disorder, the recommended dose is 200 mg per day.
If you’re taking it for fatigue or other off-label uses, the recommended dose is lower, at 100 mg per day.
It would help if you started with the lowest possible dose and gradually increased it until you found the best dose for you.
Differences in Dosages Between Modafinil & Armodafinil
There are subtle differences in how Modafinil and Armodafinil are metabolized, which leads to slightly different dosage recommendations.
Both drugs are typically taken in tablet form, but the recommended dose for Modafinil is 200 mg per day, while the recommended dose for Armodafinil is 150 mg per day.
The difference in dosage is because Armodafinil is more potent than Modafinil.
A 150 mg dose of Armodafinil is approximately equivalent to a 200 mg dose of Modafinil.
The “Officially” Unofficial Moda Dosage Guide
- 200 mg for people with narcolepsy, sleep apnea, or shift work sleep disorder

If you’re a first-time modafinil user or over the age of 65, the best dose of Modafinil to start with is 50 mg.
This is considered a low dose, and it’s less likely to cause side effects than a higher dose.
It’s also a good choice for people who are sensitive to medications.

What’s the Half-Life of Modafinil?
The half-life of Modafinil is about 15 hours.
This means that it takes about 15 hours for the level of Modafinil in your blood to be reduced by half.
It’s important to remember that the half-life is just an average, and it can vary from person to person.
Some people may find that the effects of Modafinil wear off sooner than 15 hours, while others may find that they last longer.
How Long Does Modafinil Stay in Your System?
Modafinil can stay in your system for up to four days.
If you take a 100 mg dose of Modafinil, you’ll still have 50 mg in your system after 15 hours.
And you’ll still have 25 mg in your system after 30 hours.
This is why it’s important to start with a low dose and increase gradually.
If you take too high of a dose, the effects will be too strong and last too long.
What’s the Half-Life of Armodafinil?
The half-life of Armodafinil is about 12 hours.
This means that it takes about 12 hours for the level of Armodafinil in your blood to be reduced by half.
As with Modafinil, the half-life is just average, and it can vary from person to person.
Some people may find that the effects of Armodafinil wear off sooner than 12 hours, while others may find that they last longer.
Microdosing is when you take a very small dose of a drug.
The idea is that you get all the benefits of the drug without drawbacks.
For example, you might take a tiny dose of LSD to boost your creativity without experiencing any hallucinations.
Or you might take a small dose of Modafinil to improve your focus without experiencing any side effects.
The problem with microdosing is that it’s hard to know if it’s working.
There’s no scientific evidence to suggest that microdosing Modafinil is effective.
And because the dose is so small, it’s possible that you won’t experience any noticeable effects at all.
If you decide to microdose modafinil, start with a very low dose, such as 1/10th of a pill.
And be sure to increase the dose gradually until you find the best level for you.
50mg Modafinil in the Morning: Too Much or Just Right?
Before the “half-life” and benefits seem to fade significantly, 5-7+ hours of cognitive enhancement is possible.
I was no longer interested in work by early evening, which never happens at a 200mg dose. I fell asleep around 13 hours after taking the nootropic, which is 3-5 hours sooner than when I take a 200mg dose.
No adverse effects have been reported, and there have been no reports of stomach issues. Furthermore, I felt fine utilizing this dosage three days in a row and did not notice any changes in my cognitive abilities.
25mg Modafinil in the morning and 25mg after lunch:
This one was a first. It turned out to be quite beneficial. 25mg Modafinil with an espresso gave me just under four hours of solid concentration. Then I ate lunch and took another 25mg dose with another espresso. I took two 125 milligram tablets of Modafinil at 9 and 11 PM, respectively.
This strategy provided me with another four hours of perfect attendance. I fell asleep after 11-hours on average every time I tried this method. I also observed no minor adverse effects.
I loved this dosage schedule so much that I’ve utilized it regularly when I want to unwind after work and need a tiny mental boost. Highly recommended, as long as you’re not trying to move mountains. For “mountain moving,” 200mg is still appropriate.

Modafinil For ADHD & Narcolepsy
Modafinil is a medication that is used to treat narcolepsy and ADHD. It is a central nervous system stimulant that works by increasing the amount of dopamine in the brain.
Dopamine is a neurotransmitter responsible for regulating mood, motivation, and focus.
People with narcolepsy have trouble staying awake during the day and often fall asleep unexpectedly.
ADHD is a condition that is characterized by problems with focus, hyperactivity, and impulsiveness.
Modafinil can help people with narcolepsy or ADHD stay awake during the day and concentrate on tasks.
It is important to note that Modafinil is not a cure for narcolepsy or ADHD. It is also not a replacement for other treatments such as medication, therapy, or lifestyle changes.
If you have narcolepsy or ADHD and are considering taking Modafinil, it is important to speak with your doctor first. They can help you to determine if this medication is right for you, and they can also monitor your progress.
Modafinil for Cognitive Enhancement
Some people also use Modafinil for cognitive enhancement.
Cognitive enhancement uses drugs or other methods to improve cognitive function, such as memory, intelligence, and attention span.
Some people believe that Modafinil can help to improve cognitive function in healthy people. However, there is limited scientific evidence to support this claim.
One study found that Modafinil improved task enjoyment and motivation in a group of healthy adults. However, there was no difference in cognitive performance between the group who took Modafinil and the control group.
Another study found that Modafinil did not improve memory or attention in healthy young adults.
There is also some evidence to suggest that Modafinil may improve cognitive function in people with Alzheimer’s disease, Parkinson’s disease, and multiple sclerosis. However, more research is needed to confirm these findings.
The Side Effects of Modafinil & Armodafinil
Both Modafinil and Armodafinil are generally well-tolerated. The most common side effects include headache, nausea, and insomnia. These side effects are typically mild and go away on their own. Rarely more serious side effects have been reported. These include anxiety, irritability, dizziness, and heart palpitations. If you experience these side effects, stop taking the drug and call your doctor right away.
Recommended Dosage Schedule for New Users
If you’re new to Modafinil or Armodafinil, it’s best to start with a lower dose and gradually increase until you find the right level. The recommended starting dose of Modafinil is 200 mg per day. For Armodafinil, the recommended starting dose is 150 mg per day.
Modafinil vs Adderall: Which is Better?
Adderall is a powerful stimulant that is used to treat ADHD. It can also be used for narcolepsy. Modafinil is a milder stimulant that is used to treat narcolepsy. While both drugs can be effective, they have different risks and benefits.
Adderall is more likely to cause side effects such as insomnia, anxiety, and heart palpitations. Modafinil is less likely to cause these side effects, but it may cause headaches and nausea. Ultimately, deciding which drug to take depends on your individual needs and preferences. If you have any concerns, be sure to talk to your doctor.
Armodafinil vs Modafinil: Which is Better?
Armodafinil is the newer version of Modafinil. It has a longer half-life, so it lasts longer in the body. Armodafinil is also less likely to cause side effects like headaches and nausea.
However, Armodafinil is more expensive than Modafinil. Ultimately, deciding which drug to take depends on your individual needs and preferences. If you have any concerns, be sure to talk to your doctor.
