Many drugs besides quetiapine may affect the heart rhythm (QT prolongation), including amiodarone, moxifloxacin, procainamide, quinidine, sotalol, thioridazine, among others.

Other medications can affect the removal of quetiapine from your body, which may affect how quetiapine works. Examples include azole antifungals (such as itraconazole, ketoconazole), macrolide antibiotics (such as erythromycin), rifamycins (such as rifampin), drugs used to treat seizures (such as carbamazepine, phenytoin), among others.

Tell your doctor or pharmacist if you are taking other products that cause drowsiness including alcohol, antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, and narcotic pain relievers (such as codeine).
