Interactions

Drug-drug. Aminoglycosides, loop diuretics: increased risk of nephrotoxicity

Probenecid: decreased excretion and increased blood level of cefepime

Drug-diagnostic tests. Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, bilirubin, blood urea nitrogen, creatinine, eosinophils, gamma-glutamyltransferase, lactate dehydrogenase: increased levels

Coombs' test, urinary 17-ketosteroids, nonenzyme-based urine glucose tests (such as Clinitest): false-positive results

Hemoglobin, platelets, white blood cells: decreased values

Drug-herbs. Angelica, anise, arnica, asafetida, bogbean, boldo, celery, chamomile, clove, danshen, fenugreek, feverfew, garlic, ginger, ginkgo, ginseng, horse chestnut, horseradish, licorice, meadowsweet, onion, papain, passionflower, poplar, prickly ash, quassia, red clover, turmeric, wild carrot, wild lettuce, willow: increased risk of bleeding

Patient monitoring

• Assess baseline CBC and kidney and liver function test results.
• Monitor for signs and symptoms of superinfection and other serious adverse reactions.
• Monitor for inflammation at infusion site.
• Be aware that cross-sensitivity to penicillins may occur.

Patient teaching

• Instruct patient to report reduced urinary output, persistent diarrhea, bruising, petechiae, or bleeding.
• Caution patient not to take herbs without consulting prescriber.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and herbs mentioned above.
