The patient experienced a ventricular tachycardia leading to cardiac arrest and was found to have a prolonged QT interval. Although citalopram is eliminated more slowly in patients with mild to moderate renal impairment a dose adjustment is not necessary. However, no information is available on treatment of patients with severely reduced renal function and prescribers are advised to use caution.

Consult your healthcare professional before taking or discontinuing any drug or commencing any course of treatment. Summary Long qt syndrome is found among people who take Plaquenil, especially for people who are female, 60+ old also take medication Quinine, and have Muscle spasms. This study is created by eHealthMe based on reports of 48,911 people who have side effects when taking Plaquenil from Food and Drug Administration FDA. The absence of drugs from these lists should not be considered an indication that they are free of risk of QT prolongation or torsades de pointes. Many medicines have not been tested for this risk in patients, especially those with congenital long QT syndrome. QT prolongation is a measure of delayed ventricular repolarisation, which can cause Torsades de Pointes, ventricular tachycardia, and sudden death. In elderly patients, patients with reduced hepatic function, patients who are CYP2C19 poor metabolisers, and patients taking CYPC19 inhibitors (eg, cimetidine and omeprazole), the maximum dose should not exceed 20 mg a day because these factors lead to increased blood levels of citalopram. Plaquenil and citalopram qt prolongation Ask the Expert QT Interval and Antidepressants, Will you have Long qt syndrome with Plaquenil - eHealthMe Ocular side effects hydroxychloroquinePlaquenil rob holland Patients should be screened for risk factors for QT prolongation before starting treatment with citalopram. Citalopram should be stopped and specialist advice sought in patients who have significant QTc prolongation QTc 500 ms or an increase of 60 ms unless there are compelling reasons to continue. Reminder Citalopram and QT Prolongation. DRUGS TO BE AVOIDED BY CONGENITAL LONG QT PATIENTS. Escitalopram and QTc prolongation. Core tip Long QT syndrome is a cardiac conduction disorder characterized by prolongation and increased dispersion of ventricular repolarization, manifested by lengthening of the QT interval on the surface electrocardiography. This review furnishes important key points for preoperative optimization, intraoperative anesthetic agents and postoperative care in order to fill the lack of definitive. WebMD provides information about interactions between Citalopram Oral and qt-prolonging-agents-hydroxyzine. QTc prolongation was identified in 12 patients 16.4% among the entire study sample and in 7 patients 21.7% in the subgroup of patients ≥60 years old. The prevalence of QTc prolongation increased with citalopram dose in the entire study population P =.016. This trend was also observed in patients ≥60 years old but did not meet statistical significance.
