Modalert vs Waklert

Modalert and Waklert are both non-amphetamine supplements manufactured by Sun Pharmaceutical Company Ltd based in India. They are generic versions of a drug called Modafinil and were primarily designed to promote alertness and wakefulness and have been used by individuals suffering from narcolepsy, sleep apnea, and excessive sleepiness. They have widely been used off-label to enhance cognitive performance, improve memory and promote motivation.  When comparing Modalert vs Waklert it is important to understand their similarities and their differences.

Even though these two have similar, if not identical characteristics, there are some fundamental differences in their pharmacology and effects that make some users prefer one over the other. To help you choose one of this two that is right for your needs and body, we will look at some of the major similarities and differences with respect to chemical structure, mode of action, and effects to the body.

The main chemical difference between Modalert vs Waklert is that Modalert has two enantiomers (R and the S enantiomers) while Waklert has only one enantiomer (R- enantiomer). Modalert comes from Modafinil, while Waklert comes from Armodafinil. Waklert is often considered to be more purified and stronger than Modalert with a little more intense and lasting effects.

Both Modalert vs Waklert work by inhibiting the re-uptake of dopamine in the brain. This is what promotes feelings of pleasure, well-being, enhanced mood and motivation. They also increase the level of histamine, serotonin, and norepinephrine to bring about enhanced focus, alertness, memory, wakefulness and many other cognitive functions. Additionally, the two are known to activate orexin peptides which improve communication between the neurons in the central nervous system.

As you can see, the two drugs technically work the same way to produce more or less the same effects. The overall effects and benefits are improved wakefulness, focus, alertness and attention span as well as enhanced memory, mood, creativity and cognitive functions.

The only difference is that Waklert takes a little longer to kick into action after consumption. This is because it first needs to be broken down by the liver into modafinil for it to take effect. Also, Modalert has an additional effect of appetite suppression, which has been a great plus for those seeking to lose some weight.


As earlier mentioned, Waklert is a little stronger compared to Modalert. This is why the standard recommended rate for Modalert is 200mg per day whereas Waklert only requires 150mg per day to produce similar effects. In general, Modalert has a recommended dosage range of 100mg to 400mg per day, while 50mg to 300mg of Waklert per day is considered safe enough to produce desired effects for most users.

Waklert has a longer half-life compared to Modalert. For this reason, the effects of Waklert take longer –up to 12 hours –to wear off whereas Modalert starts to drop down after 6 hours.

Side Effects

Side effects of Modalert vs Waklert are pretty much the same. However, they are much common in some new users, or those experimenting with significantly high doses of the two drugs. Common side effects include headaches, nausea, dizziness and stomach upsets. Some Waklert users have reported a change in sleep pattern, probably due to its long lasting wakefulness effect.


Both Modalert and Waklert are great nootropic supplements used to promote wakefulness, focus, and concentration as well as enhance mood. They have been successfully used to help patients suffering from sleep disorders such as narcolepsy, sleep apnea, and excessive sleepiness. Bearing the similarities of these two in mind, you may want to try them both for yourself to determine what works best for you. However many reviews state that Modalert can be used for daily use and to opt for Waklert on days that you need an extra boost.
