Paclitaxel is a commonly used chemotherapeutic agent. To minimize the risk of hypersensitivity reactions (HSRs), which occur in approximately 16-42% of patients, premedication with dexamethasone, clemastine, and ranitidine was standard of care. As of October 2019, ranitidine is no longer available. We compared the risk of HSRs to paclitaxel with and without premedication with ranitidine, hypothesizing that the incidence of HSRs to paclitaxel will be similar. In this retrospective cohort study, all first-time paclitaxel users in the Groene Hart Hospital were included from January 2019 to August 2020. The primary outcome was the incidence of HSRs, using a Student's t-test. One-hundred and eight patients who were first-time users of paclitaxel in the Groene Hart Hospital met the inclusion criteria. Most patients were treated for breast or ovarian cancer, followed by lung cancer. Analysis of all 836 paclitaxel administrations was performed. Following 349 administrations with ranitidine as premedication, eight HSRs occurred (2.3%), while following 487 administrations without ranitidine, 12 HSRs occurred (2.5%), p-value of 0.87. An additional analysis on the occurrence of HSRs per patient was performed: 45 patients received premedication in the form of ranitidine, of which eight patients (17.8%) had a HSR. Sixty-three patients did not receive premedication in the form of ranitidine, of whom 10 (15.8%) had a HSR, p-value of .80. In conclusion, we found no difference in the incidence of HSRs during paclitaxel infusions between patients who received ranitidine as premedication versus those who did not.
