Drug Interaction Report

MONITOR: Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase plasma digoxin concentrations and half-life. The exact mechanism is unknown, but may be related to reduced renal clearance of digoxin. Data have been conflicting. The interaction has been reported with indomethacin and ibuprofen, but data for other NSAIDs are not available.

MANAGEMENT: Patients who require concomitant therapy should be monitored for altered pharmacologic effects of digoxin and for increased plasma levels. The digoxin dosage may require adjustment. Patients should be advised to notify their physician if they experience nausea, anorexia, visual changes, slow pulse, or irregular heartbeats.

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.
