Thus, smoking or caffeine intake should not influence dosing of aripiprazole (Abilify) and risperidone (Risperdal) (the metabolism of both depends on CYP2D6 and CYP3A4) (Prior and Baker, 2003; Swainston Harrison and Perry, 2004), quetiapine (Seroquel) (mainly metabolized by CYP3A4), and ziprasidone (Geodon) (mainly metabolized by an aldehyde oxidase and CYP3A4) (Prior and Baker, 2003). Of the SSRIs, fluvoxamine (Luvox, brand no longer available in the United States), fluoxetine, and paroxetine (Paxil) are the most prone to cause drug-drug interactions because they inhibit the metabolism of other medications through the P450 system, and these three medications dramatically increase TCA levels. Hemant's mother doubts on him. et al. In patients who are morbidly depressed and refractory to other treatments, electroconvulsive therapy may dramatically improve symptoms when no other treatment has worked.
The authors attributed this episode to smoking cessation. Clemow DB, Smoking is banned inside U.S. hospitals; thus, clinicians need to carefully question patients and consider smoking's effects on some antipsychotic doses in the hospital (limited or no smoking) versus those in the community (unrestricted smoking).

Trazodone (Desyrel, brand no longer available in the United States), nefazodone (Serzone, brand no longer available in the United States), and mirtazapine (Remeron) selectively block the 5-HT2A and 5-HT2C serotonin receptors. Combining serotonergic drugs is particularly risky.
