It is considered less effective than methylphenidate or amphetamine but more so than placebo for children with ADHD. Pseudoephedrine and ephedrine do not affect ADHD symptoms.Modafinil has shown some efficacy in reducing the severity of ADHD in children and adolescents. It may be prescribed off-label to treat ADHD. Non-stimulants
There are a number of non-stimulant medications, such as Viloxazine, atomoxetine, bupropion, guanfacine, amantadine (effective in children and adolescents but still not been seen for adults), and clonidine, that may be used as alternatives, or added to stimulant therapy. There are no good studies comparing the various medications; however, they appear more or less equal with respect to side effects. For children, stimulants appear to improve academic performance while atomoxetine does not.Atomoxetine, due to its lack of addiction liability, may be preferred in those who are at risk of recreational or compulsive stimulant use, although evidence is lacking to support its use over stimulants for this reason. : 13  Evidence supports its ability to improve symptoms when compared to placebo.Amantadine was shown to induce similar improvements in children treated methylphenidate, with less frequent side effects. A 2021 retrospective study showed showed that amantadine may serve as an effective adjunct to stimulants for ADHD–related symptoms and appears to be a safer alternative to second- or third-generation antipsychotics.There is little evidence on the effects of medication on social behaviors. Antipsychotics may also be used to treat aggression in ADHD. Guidelines
Guidelines on when to use medications vary by country.
