Meropenem Safety in Patients with Penicillin Allergy
Cross-reactivity Between Penicillins and Carbapenems
- The risk of cross-reactivity between penicillins and any carbapenem is only 0.87% (95% CI: 0.32%-2.32%) 2
- Multiple guidelines strongly recommend that patients with suspected immediate-type penicillin allergy can receive any carbapenem without prior allergy testing 1, 3, 4
- The Dutch Working Party on Antibiotic Policy (SWAB) guidelines recommend that patients with suspected immediate-type penicillin allergy can receive any carbapenem without prior allergy testing 1, 3

Practical Approach
- The American College of Clinical Microbiology recommends proceeding with meropenem administration without prior testing in patients with a history of penicillin allergy 1, 2
- Monitor for potential hypersensitivity reactions during the first dose, especially in patients with a history of severe reactions 2
- For patients with non-severe delayed-type penicillin allergy, carbapenems can be administered without special precautions 1, 5
