Scrupulosity
Little evidence is available on the use of medications to treat scrupulosity. Although serotonergic medications are often used to treat OCD, studies of pharmacologic treatment of scrupulosity in particular have produced so few results that even tentative recommendations cannot be made.
Oppositional defiant disorder
Psychopharmacological treatment is the use of prescribed medication in managing oppositional defiant disorder. Prescribed medication to control ODD include mood stabilizers, antipsychotics, and stimulants. In two controlled randomized trials, it was found that between administered lithium and the placebo group, administering lithium decreased aggression in children with conduct disorder in a safe manner. However, in a third study it found the treatment of lithium over a period of two weeks invalid. Other drugs seen in studies include haloperidol, thioridazine, and methylphenidate which also is effective in treating ADHD, as it is a common comorbidity.
