Interactions between your drugs

Major

nafcillin sacituzumab govitecan

Applies to: nafcillin and sacituzumab govitecan

GENERALLY AVOID: Coadministration with inducers of uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) may significantly decrease the plasma concentrations of sacituzumab govitecan and its pharmacologically active metabolite, SN-38. The proposed mechanism involves decreased exposure to SN-38, a topoisomerase I inhibitor linked to sacituzumab govitecan, which is metabolized via UGT1A1. Loss of antineoplastic efficacy may occur.

MANAGEMENT: Due to the potential loss of antitumour activity, concomitant use of sacituzumab govitecan with UGT1A1 inducers should be avoided.

Drug and food interactions

Moderate

nafcillin food

Applies to: nafcillin

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.
