Adrafinil Dosage

Adrafinil belongs to the eugeroic group of supplements, which means it promotes wakefulness. It’s known to improve wakefulness, focus and alertness while reducing fatigue and drowsiness. It has also been widely used to provide nootropic effects such as improving memory, increasing learning abilities, and improving overall brain energy. Understanding the Adrafinil dosage is crucial to getting the most out of the drug.

Adrafinil works by increasing the levels of histamine, glutamate, serotonin and dopamine which excites a lot of activities in the central nervous system. It’s used heavily by both students and workers in financial and high-tech industries who need more energy and enhanced cognitive abilities throughout the day.

Adrafinil Dosage Recommendation

The Adrafinil supplement is very powerful, as such; you must be very keen with dosage recommendation. The recommended daily dosage is between 150mg and 300mg. It’s generally recommended that you start with a lower dosage and gradually built up after you’ve understood how this drug affects your biochemistry. Ideally, only increase the Adrafinil dosage after 1-2 weeks.

Although 200mg is the most commonly recommended daily dosage by most physicians, some users have gone up to 600mg or more per day with no harm. However, this kind of experimentation should only be left to experienced nootropic users. It’s also important to note that clinical studies have revealed that increasing the dosage beyond 300mg does not lead to a significant increase in the desired effects. So it might be a good idea to stick to the lowest effective dose to avoid any chances of developing side effects.

Users are also advised not use Adrafinil on a daily basis so as to avoid tolerance. Only use this supplement on those days when you need that extra boost of concentration and mental energy. Additionally, never use Adrafinil, or any other nootropic for that matter, in combination with alcohol.

After determining your optimum dosage for Adrafinil, the next decision you will need to make is whether to take it in a single or split dose. For users just looking to stay alert and maintain maximum focus throughout the day, a split dose might be the best option. If you fall in this group, divide your daily dose into two halves, take one-half in the morning and the other half the afternoon to maintain your focus and alertness throughout the day.

On the other hand, if your primary goal of taking Adrafinil is to combat conditions such as narcolepsy, consider taking a single dose early in the morning. When using Adrafinil for shift work disorder, you should take a single dose an hour before going to work. To prevent losing sleep at night, avoid taking this supplement late in the evening.

Possible Side Effects

Adrafinil is a very potent, but also very forgiving when it comes to side effects. It’s highly tolerated with no toxicity symptoms to speak of. A few of the side effects that can be noticed in some new users or at significantly higher doses include nausea, headaches, diarrhea, rashes, stomach upsets and anxiety. These can, however, be easily reversed by reducing the dosage or temporarily discontinuing the use of Adrafinil.  Long-term use may put unnecessary strain on the liver.


Once you determine your optimum Adrafinil dosage, this drug can bring out the smart in you by improving focus and alertness as well as boosting your memory and cognitive performance.  In case of any persistent side effects, discontinue the drug and inform your physician immediately.
