Modafinil is a narcolepsy medication that is in many ways similar to Adderall and Ritalin.
💡
Studies comparing modafinil to Ritalin have shown that both are similarly effective in reducing ADHD symptoms.
⚠️
However, due to concerns about modafinil's side effects, it has not been approved as a medication for ADHD.
Modafinil is a medication currently approved to treat narcolepsy. Like Adderall and Ritalin, modafinil acts as a stimulant. For those with narcolepsy, it can help keep them awake.

Modafinil is a novel stimulant-like compound that is currently approved for the treatment of narcolepsy, and has been widely studied as a potential treatment for ADHD. Its mechanism of action is complex with evidence of effects across a wide range of neurotransmitter systems, including catecholamines, serotonin, glutamate, GABA, and orexin
Because of this, researchers have studied modafinil as a potential treatment for ADHD in children and adolescents.
These studies have generally shown that modafinil can be an effective ADHD treatment. The study below found that children who took modafinil experienced greater reductions in their ADHD symptoms and had improved overall mental health compared to those in the control group.

Modafinil vs. Ritalin
In fact, a head-to-head study comparing modafinil and Ritalin found that modafinil had a very similar level of effectiveness compared to Ritalin, which is an approved medication for ADHD:

There was also some evidence that overall, modafinil may have less severe side effects than Ritalin, though more research is needed to confirm this.
Modafinil as a treatment for ADHD
However, unlike Adderall or Ritalin, modafinil has not been approved as a treatment for ADHD in children and teenagers.
Doctors can prescribe modafinil since it is an approved medication for narcolepsy. However, it has not been officially approved as a treatment for ADHD.
What is an off-label drug?
Based on studies of modafinil, the FDA concluded that while modafinil may be effective in reducing ADHD symptoms, there are concerns about a rare but severe side effect:
“
A Food and Drug Administration advisory committee said modafinil is not safe for treating ADHD in children and adolescents by a 12–1 vote, although committee members unanimously agreed the drug was effective for that indication.
Key takeaways
There is strong evidence that modafinil may effectively treat ADHD in children and adolescents. While more extensive studies are needed to confirm this, at least one study shows that modafinil may potentially be just as effective as Ritalin in reducing ADHD symptoms.
However, it is not currently approved as a treatment for ADHD in children and teenagers. Experts at the FDA have determined that, at this point, the benefits of modafinil in ADHD have not been shown to outweigh the risks.
