Interactions between your drugs

Moderate

multivitamin with iron ceftibuten

Applies to: Tri-Vi-Sol with Iron (multivitamin with iron) and ceftibuten

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 and food interactions

Moderate

multivitamin with iron food

Applies to: Tri-Vi-Sol with Iron (multivitamin with iron)

ADJUST DOSING INTERVAL: Concomitant use of some oral medications may reduce the bioavailability of orally administered iron, and vice versa.

Food taken in conjunction with oral iron supplements may reduce the bioavailability of the iron. However, in many patients intolerable gastrointestinal side effects occur necessitating administration with food.

MANAGEMENT: Ideally, iron products should be taken on an empty stomach (i.e., at least 1 hour before or 2 hours after meals), but if this is not possible, administer with meals and monitor the patient more closely for a subtherapeutic effect. Some studies suggest administration of iron with ascorbic acid may enhance bioavailability. In addition, administration of oral iron products and some oral medications should be separated whenever the bioavailability of either agent may be decreased. Consult the product labeling for specific separation times and monitor clinical responses as appropriate.

Moderate

ceftibuten food

Applies to: ceftibuten

ADJUST DOSING INTERVAL: Food reduces the oral absorption and bioavailability of ceftibuten. According to the product labeling, administration of ceftibuten oral suspension with a high-fat breakfast decreased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) by 26% and 17%, respectively. Administration of ceftibuten capsules with a standardized breakfast decreased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) by 18% and 8%, respectively.

MANAGEMENT: To ensure maximal oral absorption, ceftibuten oral suspension should be taken at least two hours before or one hour after a meal.

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.
