Interactions between your drugs

Minor

probenecid diclofenac

Applies to: probenecid and diclofenac

Probenecid may interfere with the plasma protein binding, metabolism, and/or renal elimination of nonsteroidal anti-inflammatory drugs (NSAIDs), resulting in increased NSAID plasma levels. The risk of NSAID toxicity may be increased. Although adverse effects from this interaction have not been reported, patients receiving this combination should be monitored for increased NSAID side effects. Patients should be advised to report possible signs of NSAID toxicity such as dizziness, drowsiness, headache, tinnitus, nausea, vomiting, dyspepsia, abdominal pain, diarrhea, or black tarry stools.

Drug and food interactions

Moderate

diclofenac food

Applies to: diclofenac

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.

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.
