Tips for patients and families

Be sure to discuss all questions and instructions with your doctor or pharmacist. 

  • Tell your doctor before you receive ceftazidime if you have had an allergic reaction to a cephalosporin or penicillin antibiotic.
  • If you have allergy symptoms (listed above) or severe or watery diarrhea while you are receiving ceftazidime, tell your doctor right away.
  • If you have decreased kidney function, tell your doctor before you receive ceftazidime.
  • Ceftazidime may cause a false-positive result when checking the amount of sugar (glucose) in the urine.
  • If you are an outpatient taking ceftazidime through a portable pump (such as an Eclipse® device):
    • Finish all doses of ceftazidime as instructed by your doctor, even if you think your condition has improved;
    • Store ceftazidime in the refrigerator or on ice; and
    • Place one (1) dose of ceftazidime at room temperature about 30 minutes before the dose is received.
    • See “Do You Know…Using the Eclipse® medicine device” for details.

Always check the medication label. Many medicines look the same. Do not take any new medicine, including over-the counter medicines or supplements, without checking with your doctor or pharmacist. Talk to your doctor or pharmacist about what to do in the case of a missed dose, allergic reaction, or medical emergency.
