You can purchase different doses of Modafinil, but they tend to only be available in doses that range from 100mg-400mg per tablet. It has been known for people to actually take Modafinil in higher doses, as they might want to get more of an effect from it, plus, it can actually produce a euphoric high. We want to enlighten you about what happens when you overdose on Modafinil and what the risks could be from taking too many of these tablets.


What is the regular Modafinil dosage?

Modafinil can be quite difficult to get hold of, as it’s only a prescribed drug. It’s usually just used to treat certain sleeping disorders like narcolepsy. However, Modafinil has also been proved to be very useful for people that have ADD and ADHD, because it can make you more focused. If you do get Modafinil prescribed to you, it will more than likely be in a dosage between 100mg and 200mg. If you need a higher dosage, the maximum they can provide you with is 400mg per day.

The doctor will also consider other factors before they prescribe you the correct dosage, for instance, how much the person weighs. The Modafinil tablets are able to last quite a long time and will actually work for around 15 hours. Therefore you will only need to take one tablet per day, and you will have to take it in the morning.

There are other similar versions of Modafinil, they are called Armodafinil, modvigil, and artvigil. These are known to be a little bit stronger compared to Modafinil, so a doctor will probably prescribe you 150mg of these.


Where can you get Modafinil?

Even though you can usually only get this medication through a prescription, you can also quite easily buy it online as well. The reason why you can actually purchase it without a prescription online is that there are actually some legal loopholes about the sale of Modafinil. This means that you can actually purchase the medication without a prescription and get it shipped to you from various other countries.

Online websites like Afinil Express will let you purchase Modafinil online and then you will be able to get it sent to you from overseas. This is actually a very simple method of being able to purchase Modafinil without any prescriptions from the doctor, plus, the tablets from here are a lot cheaper than a prescription would cost you anyway.

There are four different versions of the medication that will be sold on most online sites; this includes Modvigil, Modalert, Artvigil, and Waklert.


Why do some people take a larger dose of Modafinil?

Doctors would never recommend that you have a larger dose than 400mg of Modafinil. They would only usually prescribe you between 100mg to 200mg. However, if you do want a larger dose then you can easily purchase this online at a lot cheaper price, so really you can take however much you want to. Some people do take larger doses of Modafinil and here’s why:

1. To get high

Modafinil does produce a slight high once you have taken it and sometimes people may take more of the drug to be able to get this high. If you do want to gain this mild high then ideally you will need to take around 800mg of Modafinil. However, you may achieve a high but it will come with side effects, so it’s not recommended to do, as it could make you feel quite ill and could always lead to more serious complications.

It has been known that some people have even taken as much as 2000mg and 4000mg to be able to gain this high, but the side effects for them have actually lasted for up to four days, and it can be very dangerous.

2. Not knowing the correct dosage

It’s quite easy to get the right information for the correct dosage for the drug that you have. Usually, you will be given the exact dosage instructions on the Modafinil box when you receive it from your doctor. Not only this, but a doctor will also want to monitor you just in case you get any side effects after you’ve taken them.

However, when you purchase Modafinil online, it’s really down to you how many tablets you take, which is why it can be quite dangerous. There have been many comments on websites about people taking three to four Modafinil tablets the first time they take it. This has purely been because they look a similar size pill compared to an Aspirin or Tylenol.

It’s very important that you don’t do this because this is actually three or four times the recommended dosage that you should be taking.

3. Drug tolerance

It’s a little bit controversial about whether or not you can actually gain a tolerance from taking Modafinil. There have been a lot of reports on various websites about people saying that they have actually found that they have a tolerance to Modafinil. However, there has actually been scientific research into this as well, and they didn’t find that Modafinil created any tolerance.

If you do happen to experience some type of tolerance it will make you want to take more Modafinil to try and get it to start working more; therefore, you will more than likely take a larger dose. However, this is very dangerous because the larger the dose you take, the more likely you will experience very bad side effects for a longer period of time.

So, what’s the recommended dosage for Modafinil?

Doctors would recommend that you take a dosage of either 100mg or 200mg if you want to get good results from it. You may have the 200mg tablets, and if you take these and start feeling quite a few side effects after taking them, then it’s probably best that you try taking the 100mg tablet. These will more than likely suit you a lot more, and it won’t give you any of the nasty side effects, but it should still be able to work and keep you feeling awake.

You will find that everyone copes with different doses differently, so if you know someone who takes more, then this won’t necessarily work for you, because your body is different. Therefore it’s best to take note of what your body is telling you that way you will know what dosage works for you best.


Other doses

You may find that some people will have even lower doses than 100mg. An example of this would be someone who has a liver disorder because your liver actually metabolizes Modafinil. Therefore if your liver doesn’t work in the correct way, then it may take a bit longer to filter and metabolize the medication. This means that the effects could actually last you longer so you won’t need as much.

If someone who has a liver problem takes a dosage that is too much for them, then the effects of this drug may last a lot longer for them, which could actually lead to them being awake all night, so that will completely mess up their routine and make them tired during the daytime.

People who have liver disorders are not the only ones who may need a smaller dosage, as older people probably will as well. This is because once you reach the age of 50 your metabolism and kidney function will start to slow down a bit. This means that the Modafinil will be in your system a lot longer compared to someone who’s younger. Therefore if someone who is older takes Modafinil at a stronger dosage, it could lead to the same situation of them being awake for longer and getting more side effects, which means they would have overdosed.

If you happen to be either of these people, then it’s best to start at 50mg and work your way up.


What happens if you do overdose on Modafinil?

If you do happen to take more of the Modafinil tablets that are recommended or you take a dose that’s too high, then this is an overdose. If you do overdose on Modafinil, then you will more than likely just get increased side effects, and if you overdose by a lot, these side effects can last quite a few days.


What does cause an overdose?

Usually, if you take more than 400mg of Modafinil, then you will start feeling quite a few more side effects compared to what you usually would, but it’s more common for you to get stronger symptoms when you have taken around 800mg of Modafinil. There has been one case study of a young woman who is 24 years old. She accidentally took 400mg of Modafinil, when her regular dosage was 200mg. She ended up going to the hospital where they found out that her blood pressure was 168/131mmHg and her heart rate was 168 beats per minute.

She was at a very large risk of causing herself a heart attack because your heart should usually beat around 80 times per minute and your blood pressure should usually read 120/80 mmHg. Therefore she had to actually be monitored at the hospital, but she was discharged after a couple of hours and didn’t have any long-lasting side effects.

There has also been another study of an elderly man of 65 years, who took 800mg of Modafinil by accident because he thought it was an aspirin. He only had the side effects of a high blood pressure, which was recorded as 137/78, plus, he couldn’t sleep at all. Overall, many people react completely differently to different doses that they take; therefore, you need to be careful over what dose you actually take. This is why it’s best to work your way up by starting at a low dose of Modafinil.


What are the symptoms of a Modafinil overdose?

Usually, if you do happen to overdose on Modafinil, you will have symptoms of the side effects that you would get from it.

Steven Johnson syndrome:

There has been one link between Steven Johnson Syndrome and Modafinil, as a case study participant actually managed to develop it after taking Modafinil. Steven Johnson Syndrome is a type of severe allergic reaction, it is rare, but it’s very serious if you do get it. First of all, you may feel like your skin is burning or tingling if you get this. Afterward, it will then develop into ulcers around your mouth and mucous membranes. These are also known to spread quite easily and will be painful if you do get them.

There has been one case that was recorded where someone took 4000mg of Modafinil, and they ended up having heart palpitations, insomnia, extremely painful headaches and a dry mouth for four days. He was okay after the four days, and there were no long lasting side effects. However, everyone does react differently to different dosages.


Can it kill you if you do overdose on Modafinil?

It will reassure you that you cannot die directly from taking too much Modafinil. However, it could lead to complications because if you get Steven Johnson Syndrome after taking an overdose of Modafinil, then it’s very rare, but it could lead to death. If you do overdose on Modafinil, it will be a very uncomfortable and unpleasant experience, and you should seek medical attention if you do.

It has been worked out that if you were to die directly from taking Modafinil, then the average male would have to take around 75,000mg of the drug, for this to risk death. It’s also been discovered that if you do happen to accidentally take one too many tablets of Modafinil , then it will more than likely give you side effects of anxiety, headaches, hallucinations, and extreme fatigue.

If you do overdose on Modafinil, it will not create any long-lasting side effects no matter what dosage you take. There is one thing you should never do though, and that is mix the drug with other drugs and alcohol, otherwise, this could be fatal.


What do you do if you do overdose on Modafinil?

1. Drink lots of water

This is because it’s known to cause you to dehydrate and drinking a lot of water can actually solve some of the symptoms that you might get from it. Some of these symptoms include headaches and dizziness. If you do take Modafinil, it’s best to try and drink six liters of water that day, that way you won’t get as many symptoms.

2. Relaxation techniques

If you do experience some of the symptoms like headaches, insomnia, and anxiety, then it’s actually best to try and relax your central nervous system. This is because it will actually lower your blood pressure, your anxiety, and your heart rate too. Therefore try to sit in a calm dark room and just close your eyes to allow yourself to relax. This will manually allow you to override your central nervous system and make you relax.

3. Take L-Theanine

L-Theanine is actually found in green tea, and this is a very handy companion supplement for Modafinil. It is actually able to stop the symptoms of a Modafinil overdose and will slow your heart rate back down and lower your blood pressure as well. It could take up to 45 minutes to start working, and a normal dose of L-Theanine that you should take is around 400mg.

4. Go to your doctors

If you do think that you’ve taken an overdose of Modafinil, it’s very important that you go and see a doctor straight away. This is because you don’t want it to lead to more serious things.



Modafinil is very safe to use drug, but you do need to be careful if you do take an overdose though. It’s best not to exceed 400mg of it per day. You may not get any symptoms of an overdose if you do and this is because everyone reacts differently. It’s best to stick to the correct amount of dosage; otherwise, you could get side effects.
