Interactions between your drugs

Moderate

ampicillin kanamycin

Applies to: Omnipen-N (ampicillin) and kanamycin

ADJUST DOSING INTERVAL: Ampicillin may inactivate aminoglycosides in vivo and in vitro. The mechanism is complexation with the aminoglycoside. Typically, this effect is significant only in patients with renal failure or if the agents are mixed in the same IV container or line. Lower serum aminoglycoside levels may be seen, and dosage adjustments may be necessary.

MANAGEMENT: Ampicillin and aminoglycosides should be administered separately during combined therapy.

Drug and food interactions

Moderate

ampicillin food

Applies to: Omnipen-N (ampicillin)

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.

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.
