Interactions between your selected drugs
propranolol ↔ risperidone
Applies to:Inderide (hydrochlorothiazide/propranolol) and risperidone
MONITOR: Phenothiazines and neuroleptic agents may potentiate the hypotensive effect of some medications secondary to their peripheral alpha-1 adrenergic blocking activity. Orthostatic hypotension and syncope associated with vasodilation may occur, particularly during initial dosing and/or parenteral administration of the phenothiazine or neuroleptic.
MANAGEMENT: Close clinical monitoring for development of hypotension is recommended if phenothiazines or neuroleptic agents are used in patients receiving antihypertensive medications or vasodilators. A lower starting dosage and slower titration of the phenothiazine or neuroleptic may be appropriate, especially in the elderly. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia. Patients should also avoid driving or operating hazardous machinery until they know how the medications affect them.
hydrochlorothiazide ↔ risperidone
Applies to:Inderide (hydrochlorothiazide/propranolol) and risperidone
MONITOR: Some neuroleptic agents may cause prolongation of the QT interval. While clinical data are lacking, the coadministration of other agents that can produce hypokalemia and/or hypomagnesemia (e.g., potassium-wasting diuretics, amphotericin B, cation exchange resins, stimulant laxatives) may result in elevated risk of ventricular arrhythmias, including ventricular tachycardia and torsade de pointes. In addition, neuroleptic agents may potentiate the hypotensive effect of diuretics secondary to their peripheral alpha-1 adrenergic blocking activity. Orthostatic hypotension and syncope associated with vasodilation may occur, particularly during the initial dose titration period of neuroleptic therapy.
MANAGEMENT: Caution is advised when neuroleptics must be used concomitantly with medications that can cause potassium and/or magnesium disturbances. Serum electrolytes should be monitored and any abnormalities corrected prior to initiating therapy with a neuroleptic. Close clinical monitoring for development of hypotension is recommended if neuroleptic agents are prescribed with a diuretic medication. Patients should be advised to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia. A lower starting dosage and slower titration of the neuroleptic agent may be appropriate in patients receiving antihypertensive therapy, especially if they are elderly.

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. |
