Interactions between your drugs

Minor

ampicillin probenecid

Applies to: ampicillin / probenecid and ampicillin / probenecid

Probenecid may increase the plasma concentrations and half-lives of penicillins. The mechanism is competitive inhibition by probenecid of the renal tubular secretion of penicillins. While this interaction is often exploited to enhance the antibacterial effect of penicillins, toxicity may occur and should be considered if high penicillin dosages are administered intravenously.

Minor

probenecid oxaprozin

Applies to: ampicillin / probenecid and Daypro Alta (oxaprozin)

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

ampicillin food

Applies to: ampicillin / probenecid

ADJUST DOSING INTERVAL: Certain penicillins may exhibit reduced gastrointestinal absorption in the presence of food. The therapeutic effect of the antimicrobial may be reduced.

MANAGEMENT: The interacting penicillin should be administered one hour before or two hours after meals. Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.

Moderate

oxaprozin food

Applies to: Daypro Alta (oxaprozin)

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.
