MONITOR CLOSELY: Drugs that inhibit platelet function may increase the risk of bleeding when administered prior to, during, or after thrombolytic therapy.

MANAGEMENT: Careful monitoring for signs of bleeding, particularly at arterial puncture wounds, is recommended when thrombolytics are used concurrently or sequentially with antiplatelet agents. Some authorities recommend avoiding the initiation of platelet aggregation inhibitors within the first 24 hours following thrombolysis treatment. Local guidelines and prescribing information for individual thrombolytic drugs should be consulted for further recommendations.

Drug and food interactions

Moderate

aspirin food

Applies to: Extra Strength Bayer (aspirin)

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.

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

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.
