ibuprofen argatroban

Applies to: ibuprofen / phenylephrine and argatroban

GENERALLY AVOID: Theoretically, the coadministration of nonsteroidal anti-inflammatory drugs (NSAIDs) and thrombin inhibitors may potentiate the risk of bleeding. NSAIDs interfere with platelet adhesion and aggregation and may prolong bleeding time in healthy individuals. While these effects are generally slight and of relatively short duration for most NSAIDs (except aspirin) at recommended dosages, they may be of pronounced clinical significance when combined with the effects of thrombin inhibitors on the clotting cascade. NSAIDs are also known to cause dose-related gastrointestinal bleeding, which may be complicated by anticoagulant therapy. However, little clinical data exist regarding an actual interaction.

MANAGEMENT: Until further data are available, products containing NSAIDs, especially if given chronically or in high dosages, should preferably be avoided in patients receiving thrombin inhibitors. Close clinical and laboratory observation for bleeding complications is recommended if concurrent therapy is necessary.

Drug and food interactions

Moderate

Applies to: ibuprofen / phenylephrine

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.

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

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.
