However, there is substantial evidence from placebo-controlled maintenance studies in adults with MDD that antidepressants delay the recurrence of depression. (Brexpiprazole label, Warnings and precautions)

…placebo-controlled trials of adult patients with major depressive disorder, the proportion of patients with shifts in fasting glucose from normal (<100 mg/dL) to high (≥126 mg/dL) was greatest in the VRAYLAR 3 mg per day + antidepressant therapy arm (3.2%) compared with those taking VRAYLAR 1.5 mg per day + antidepressant therapy (2%) or those placebo-treated (1.3%). (Cariprazine label, Warnings and precautions)

Such drugs include specific antidepressants, phenothiazines, carbamazepine, and Type 1C antiarrhythmics (e.g., propafenone, flecainide, and encainide). (Clozapine label, Drug interactions)

In contrast, drugs that are inhibitors of cytochrome P450 isozymes, e.g., antidepressants, may be expected to have little effect on valproate clearance because cytochrome P450 microsomal mediated oxidation is a relatively minor secondary metabolic pathway compared to glucuronidation and beta-oxidation. (Divalproex (valproate) label, Drug interactions)

Such drugs include phenothiazines, cisapride, bepridil, tricyclic antidepressants, certain oral macrolides, and certain fluoroquinolones. (Dofetilide label, Warnings)
