Edit list (add/remove drugs)

Interactions between your drugs

Moderate

dicloxacillin fecal microbiota, live

Applies to: Dynapen (dicloxacillin) and fecal microbiota, live

ADJUST DOSING INTERVAL: Antibiotics may interfere with the therapeutic effects of fecal microbiota, which contains live bacteria. The mechanism may be related to the antibiotic inactivating the bacteria or reducing bacterial replication. In clinical studies an antibiotic washout period between 24 to 72 hours was required prior to the rectal administration of fecal microbiota.

MANAGEMENT: Although data are limited, it may be prudent to have an antibiotic washout period between 24 to 72 hours prior to administration of the rectal formulation of fecal microbiota. In addition, the manufacturer recommends avoiding oral antibiotics for up to 8 weeks after administration of the rectal formulation of fecal microbiota.

Drug and food interactions

Moderate

dicloxacillin food

Applies to: Dynapen (dicloxacillin)

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.
