Piperacillin-Tazobactam Allergies: An Exception to Usual Penicillin Allergy.

CONCLUSIONS: There is growing utilization of PT and corresponding cases of suspected allergies. The majority of suspected PT allergies had increased risk for recurrent infections. Unlike other penicillin allergy, there is a high rate of genuine PT allergy (up to 30%) and a poor NPV of ST (up to 70%). DPT remains the gold standard for accurate diagnosis, and all patients with a suspected allergy should undergo thorough allergy workup. PMID: 33474862 [PubMed]
