Provigil (modafinil) and Nuvigil (armodafinil) are wakefulness promoting drugs used for combating excessive sleepiness. Here we look at the difference between Provigil and Nuvigil. They work in the same way as they contain only slightly different formulas of the same basic chemical.

Who makes this stuff?

Provigil and nuvugil were developed by the same company, the slightly icky sounding Cephalon Inc. Euurgh…makes me think of a big wet brain.

Nowadays there are several brand names of modafinil including Modalert, Provigil, Modavigil and Alertec. All of these are same product and should have the exact same effect on the user. Should but reports online about effects from the different brands do seem to show some difference in people. Nuvigil is also sold under the names Waklert, Artvigil and R-Modawake. Again these are all the same so should give the same effect in users.

So what are the effects?

If you believe everything you read online then taking either of these drugs every day will help you climb the ranks to CEO of Shell in just 3 months. Unfortunately, this is not the case. The truth is still pretty awesome though. Provigil/Nuvigil will give you the focus you need to develop and carry out your challenging job or study schedule and keep your sleep time to a minimum. That said, it is totally possible to sleep on these drugs as they do not function like a typical stimulant. If you have ever watched Iron Man and thought “goddamn that Tony Stark is one driven son of a biitch, I wish I could do that” then this is the drug you need.

What is the main difference between Provigil and Nuvigil?

Nuvigil (armodafinil) is a racemic of modafinil. In chemical terms it can be written R-Modafinil which indicates that is just the R enantiomer of the modafinil molecule. Makes perfect sense right?

In simple terms Provigil and Nuvigil are slightly different versions of the same drug both made and developed by the same company.

The half life of Nuvigil is longer than Provigil. For the user this means two things, firstly, it can take longer to feel the effects of Nuvigil or the effects may creep in more subtly, secondly, it takes longer to leave your body.

Leaving your body longer is the important for most users to be aware of. With Nuvigil it is a good idea to make sure you take your dose early in the day if you intend to sleep that night.

Still not sure which one is for you? The best way to choose is simply to try both out. The folks at ModafinilCat have a low cost sample pack which has Provigil and Nuvigil in. You can buy it direct from them here or check out some other suppliers on our comparison chart here.
