Interactions between your selected drugs
hydrochlorothiazide ↔ arsenic trioxide
Applies to:Inderide (hydrochlorothiazide/propranolol) and arsenic trioxide
MONITOR CLOSELY: Arsenic trioxide can cause QT interval prolongation and complete atrioventricular block. Since hypokalemia and hypomagnesemia are known risk factors for arrhythmia associated with QT prolongation, coadministration of arsenic trioxide with agents that can cause significant potassium and/or magnesium loss (e.g., potassium-wasting diuretics, amphotericin B, cation exchange resins) may increase the risk of ventricular arrhythmias such as torsade de pointes and sudden death.
MANAGEMENT: Caution is advised if arsenic trioxide must be used concomitantly with medications that can cause significant potassium and/or magnesium loss. Serum electrolytes should be evaluated and any abnormalities corrected prior to initiating therapy with arsenic trioxide. During therapy, potassium concentrations should be kept above 4 mEq/dL and magnesium concentrations above 1.8 mg/dL. Patients should also have frequent ECGs and be monitored for serious arrhythmias when QT intervals are prolonged. Patients should be advised to seek medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, palpitations, or syncope.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
