Answer

Citalopram (Celexa) carries a risk of dose-dependent QT prolongation. Because of the risk for QT prolongation, citalopram is contraindicated in individuals with congenital long QT syndrome and the dose should not exceed 40 mg/day. Do not exceed a dose of 20 mg/day when coadministered with CYP2C19 inhibitors (eg, cimetidine, fluconazole, omeprazole). [53, 54]
