Finding the Ideal Modafinil Dosage: What You Need to Know

I was “cracked” out. Modafinil isn’t a stimulant, but this wasn’t how the “high” typically felt. I upped my Modafinil dosage, and 400 mg was way too much for my needs.

See, I’d typically take 200 mg 1-3 times per week, but my boy convinced me to up the ante. He was a bit of a substance abuser, but a charismatic one.

After relaying how he takes 400-800 mg of Modafinil every single day, I was convinced I could take more and work from early morning to the next morning without issue.

I woke up at 5:30 AM and quickly ate some food before popping 200 mg of Modafinil. Then I down some coffee and got to work.

I wasn’t surprised yet. I crushed work for around seven hours before taking a lunch break. My normal Modafinil dosage ensured great productivity. Then I popped another 200 mg of Modafinil around 1:30 PM.

Not my best idea. While the focus was impressive, I quickly noticed a lot of side effects. My stomach was almost instantly upset. A headache came on around an hour later, and it wouldn’t go away – no matter how much water I downed.

I worked for a couple more hours. Then I went and laid down. I couldn’t sleep, but the fetal position made my stomach feel a little better.

My day of ultra-productivity turned into browsing Instagram in bed as I waited for my stomach ache to go away. 400 mg was not the ideal Modafinil dosage for me.

Ideal Modafinil Dosage

I’m no doctor. This is not medical advice. You should ALWAYS consult your primary care physician before taking any pharmaceutical drug. Your doctor will let you know whether Modafinil is safe for you or not.

The Ideal Modafinil Dosage From a Scientific Point of View

You can buy Modafinil online in 100-200 mg pills. If you get a prescription from the doctor, you’ll find similar doses of 100-200 mg pills.

Officially, Modafinil is prescribed to be taken once a day at 100-200 mg. Doctors do not recommend patients taking the smart drug for narcolepsy or shift sleep disorder to take more than 200 mg as their Modafinil dosage.

While doses of up to 400 mg have been shown to be tolerated without issue (not for me), there has been little evidence that an increased dose adds benefit.

Many users don’t find an increase in focus and cognition when upping their Modafinil dose. As 200 mg of Modafinil has a 12-15 hour half-life, it can be difficult to notice any additional effects.

The evidence isn’t there, but many medical professionals also suggested paying attention to blood pressure and one’s liver when taking Modafinil doses between 400-1,000 mg daily. The literature isn’t conclusive from this standpoint. 

Overall, most of the literature and studies have shown 200 mg to be the ideal Modafinil dosage for most users – especially individuals using the pharmaceutical drug as a nootropic.

My Modafinil Dosage Recommendations

If you’re new to Modafinil or looking to tweak your dosage, here are a few things I’ve noted when trying different dosing protocol:

– 50 mg –

50 mg Modafinil dose didn’t do much for me. I felt a little increase in cognition for 2-3 hours after the effects kicked in, but it wasn’t strong.

Unless you’re new to Modafinil and just testing the smart drug out, I wouldn’t recommend such a small dose.

If you want to use 50 mg of Modafinil, you can split a 100 mg Modafinil dosage in half using one of these.

-100 mg –

For Modafinil newbies, 100 mg is a great dose to start things off. While Modafinil has a half-life of 12-15 hours, I noted the effects started to wear off around 7-8 hours after taking 100 mg.

If you’re looking for increased focus during a typical “9-5” workday, then a 100 mg Modafinil dosage could be ideal.

It’s important to note that certain users don’t “feel” much after taking 100 mg of Modafinil. If you take this dosage and don’t notice improved focus, upping the dose is advised.

– 200 mg –

For users looking at Modafinil as a smart drug, 200 mg seems to be the ideal dose. Personally, the only Modafinil dosage I take these days is 200 mg.

At 200 mg of this nootropic, most users feel all the effects of the smart drug with little to no side effects.

As there’s little evidence to suggest more than 200 mg of Modafinil adds benefit, I would recommend most users stick with this dose.

From a dosing perspective, I’ve yet to note a huge benefit between taking 200 mg at once and 100 mg at breakfast and 100 mg after lunch.

Some users find split dosing is beneficial. You’ll have to test things out and find what works for you.

– 300 mg –

I have experimented with 300 mg of Modafinil from time to time. Normally, I do this with split dosing.

I’ll take 200 mg in the morning, then take another Modafinil dose of 100 mg after eating a late lunch.

I find Modafinil’s strongest effects kick for an extra hour or two when following this dosing protocol. I also found 300 mg of Modafinil makes it nearly impossible to get to sleep before 3-4 AM.

I also noted a little “hangover” the next morning after taking 300 mg of Modafinil the day before. Overall, I wouldn’t recommend 300 mg over 200 mg of the smart drug – unless you need that extra 1-2 hours of focus.

-400 mg –

The one time I upped my Modafinil dosage to 400 mg was enough. I’ll never do that again. I didn’t notice much added benefit. The negatives of increasing my dose far outweighed the positives.

Others have found 400 mg to be necessary. However, most of these individuals also have taken the smart drug for years on end or take the pill daily. Mainly, they messed up their Modafinil tolerance.

More Modafinil?

I’ve never taken more than 400 mg of Modafinil in a single day. I never plan to, and I certainly wouldn’t recommend you do, either.

My friend who occasionally takes 800 mg of Modafinil in a single day is an anomaly. He’s a substances user who probably had his brain “rewired” through years of recreational drug and nootropic use.

For the vast majority of smart drug users, you’ll do more harm than good by ever upping your Modafinil dosage above 400 mg. For the vast majority of individuals, 200 mg of Modafinil will suit you.

Finding the Ideal Modafinil Dosage: What You Need to Know

I’m no doctor, but I’ve taken Modafinil for years, and I’ve studied some of the scientific literature on the smart drug.

If you don’t have substance abuse issues and are new to smart drugs, stick to a 200 mg Modafinil dosage. You’ll find increase cognition, focus, and productivity – without many of the negative side effects.
