Interactions between your drugs

Moderate

cephalexin indium oxyquinoline In-111

Applies to: Biocef (cephalexin) and indium oxyquinoline in-111

MONITOR: Certain medications may decrease chemotaxis and cause false-negative results with Indium In-111-labeled leukocyte studies.

MANAGEMENT: Clinicians should be aware of possible diagnostic interference in patients who are on long-term antibiotic treatment, corticosteroids, interleukin-2, parenteral nutrition, or high doses or supratherapeutic concentrations of lidocaine or procainamide.

Drug and food interactions

Moderate

cephalexin food

Applies to: Biocef (cephalexin)

ADJUST DOSING INTERVAL: Oral products containing zinc such as mineral supplements and multivitamins may interfere with the gastrointestinal absorption of cephalexin, ceftibuten or cephradine. In one pharmacokinetic study (n=12), concurrent administration of zinc sulfate (250 mg, single oral dose) and cephalexin (500 mg, single oral dose) decreased cephalexin maximum concentration (Cmax) and systemic exposure (AUC; 0-inf) by 31.05% and 27.4%, respectively. However, in the same study, when zinc sulfate was administered 3 hours after the cephalexin dose, no significant alteration in cephalexin pharmacokinetics were observed.

MANAGEMENT: Oral medications or mineral supplements that contain zinc are recommended to be administered at least 3 hours after the cephalexin, ceftibuten or cephradine dose.

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.
