Drug and food interactions

Moderate

cefpodoxime food

Applies to: Vantin (cefpodoxime)

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of cefpodoxime proxetil tablets. Following a 200 mg dose taken with food, the extent of absorption (mean AUC) was 21% to 33% higher and the mean peak plasma concentration (Cmax) 19% higher than under fasting conditions. Time to peak concentration (Tmax) was not significantly different between fed and fasted states. On the contrary, when a 200 mg dose of the suspension was taken with food, the mean AUC and Cmax were not significantly different than those under fasting conditions, although the rate of absorption was slower with food (48% increase in Tmax ).

MANAGEMENT: To ensure maximal oral absorption, cefpodoxime proxetil tablets should be administered with or immediately after a meal.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Beta-lactam antibiotics

Therapeutic duplication

The recommended maximum number of medicines in the 'beta-lactam antibiotics' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'beta-lactam antibiotics' category:

  • amoxicillin
  • Vantin (cefpodoxime)

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

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.
