Lanoxin (Digoxin Injection) and Vaprisol

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Conivaptan may increase the blood levels and effects of digoxin. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience nausea, vomiting, diarrhea, loss of appetite, visual disturbances (blurred vision; light halos around objects; green or yellow vision), or an abnormally fast or slow or uneven heartbeat, as these may be signs and symptoms of excessive digoxin levels. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with conivaptan may increase the serum concentrations of digoxin. The proposed mechanism is conivaptan inhibition of the P-glycoprotein-mediated intestinal or renal efflux of digoxin. When a single 0.5 mg dose of digoxin was administered with oral conivaptan 40 mg twice daily, digoxin peak concentration (Cmax) and systemic exposure (AUC) increased by approximately 79% and 43%, respectively, while clearance decreased by 30%.

MANAGEMENT: Serum digoxin levels and pharmacologic effects should be closely monitored following the addition or withdrawal of conivaptan, and the digoxin dosage adjusted as needed. Patients should be advised to seek medical attention if they experience signs of digoxin toxicity such as nausea, anorexia, visual disturbances, slow pulse, or irregular heartbeat.
