[Desensitization to cotrimoxazole, rifampicin and penicillin G in nine patients with prior hypersensitivity].

OBJECTIVE: To present a protocol for the administration and development technique of the desensitization regimens for cotrimoxazole, rifampicin and penicillin G hypersensibility. METHOD: A review of the available desensitization protocols for these antibiotics and a retrospective study of desensitization processes undertaken in the center from 1998. A development technique of the antibiotic dosages was designed. RESULTS: Desensitization regimens for cotrimoxazole, rifampicin and penicillin G undertaken in the center in 9 patients came from a protocol by Glucksteins et al., Holland et al. and Wendal et al., respectively. After the literature review and the satisfactory results that allowed subsequent antibiotic administration in the 9 cases, these regimens were established as protocols of the center. CONCLUSIONS: Dosage development and patient administration have a practical application and can help to decrease the potential mistakes related to the complexity of the process.
