Interactions between your drugs

Major

vasopressin sparfloxacin

Applies to: vasopressin and sparfloxacin

CONTRAINDICATED: Sparfloxacin may cause dose-related prolongation of the QT interval in some patients. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. Torsade de pointes has been reported in a few patients receiving sparfloxacin alone and with antiarrhythmic agents like amiodarone and disopyramide.

MANAGEMENT: Coadministration of sparfloxacin with other drugs that can prolong the QT interval is considered contraindicated.

Drug and food interactions

Moderate

vasopressin food

Applies to: vasopressin

MONITOR: Alcohol may decrease the antidiuretic effect of vasopressin. Clinical studies found that plasma vasopressin levels often decrease during alcohol consumption and increase upon cessation of consumption. In addition, alcoholics were found to have a more pronounced decrease in plasma vasopressin levels when drinking and suppressed vasopressin levels even during alcohol withdrawal as compared to non-alcoholic individuals. The mechanism of this interaction is not fully understood.

MANAGEMENT: Patients should be advised to abstain from alcohol during vasopressin treatment. Hemodynamic monitoring is suggested for patients known to drink alcohol while receiving vasopressin.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
Unknown No interaction information available.
