Precautions:

1. An allergy test should be performed before administration.

Cross-allergic reactions: People who are allergic to one cephalosporin or cephamycin may also be allergic to other cephalosporins or cephamycin. People who are allergic to penicillins, penicillin derivatives, or penicillamine may also be allergic to cephalosporins or cephalomycin. 5% ~ 10% of patients allergic to penicillin had allergic reaction when using cephalosporin. When the immune response is measured, 20% of patients allergic to penicillin are allergic to cephalosporins.

3. The application of this product to patients with penicillin allergy should be decided after fully weighing the pros and cons according to the patient's situation. Cephalosporins should not be used in patients with penicillin anaphylactic shock or immediate reaction.

4. Patients with a history of gastrointestinal disease, especially ulcerative colitis, confined enteritis or antibiotic-associated colitis (cephalosporins rarely produce pseudomememous colitis) should be used with caution.

5. Due to the low toxicity of cephalosporins, patients with chronic liver disease do not need to adjust the dose of this product. Patients with severe liver or kidney damage or cirrhosis should adjust the dose.
