Hemoglobin, platelets, white blood cells: decreased values
Coombs' test, urinary 17-ketosteroids, nonenzyme-based urine glucose tests (such as Clinitest): false-positive results

Patient monitoring

Monitor for extreme confusion, tonic-clonic seizures, and mild hemiparesis when giving high doses.

• Assess CBC and kidney and liver function test results.

• Monitor for signs and symptoms of superinfection and other serious adverse reactions.

• Be aware that cross-sensitivity to penicillins may occur.

Patient teaching

• Instruct patient to report reduced urine output, persistent diarrhea, bruising, and bleeding.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and herbs mentioned above.
