 Palonosetron may be safe to use in selected patients with ondansetron hypersensitivity.

TO THE EDITOR: Selective 5-HT3 receptor antagonists (5-HT3-RAs) are the cornerstone for the prevention and treatment of chemotherapyinduced nausea and vomiting.1 Therapeutic options are limited in patients with 5-HT3-RA hypersensitivity because there is a concern for cross-reactivity between different 5-HT3-RAs.2 Palonosetron is the newest 5-HT3-RA, and its chemical structure is different from the other 5-HT3-RAs (tropisetron, ondansetron, granisetron, and ondansetron).3 We describe a patient with ondansetron hypersensitivity who tolerated palonosetron. A 38-year-old woman was undergoing chemotherapy for advanced lung cancer. Seven days after she received her second cycle of Alimta/cisplatin, she noted periorbital and hand swelling, as well as urticaria on her upper and lower extremities, 20

minutes after she took her scheduled dose of ondansetron 8 mg orally. She did not have wheezing, shortness of breath, or lightheadedness. She started taking ondansetron 8 mg orally twice daily 1 week before and had never taken ondansetron or any other 5-HT3-RAs previously. Her symptoms resolved within 24 hours with oral antihistamines. She was evaluated in our clinic, and we performed skin testing. Her skin prick test with ondansetron was positive at 2 mg/mL. Prick skin test to saline was negative and histamine was positive. On the basis of published reports4,5 and our own experience with seven healthy controls and eight patients with suspected ondansetron allergy, ondansetron at 2 mg/mL is not an irritating concentration. Given her positive skin test and convincing clinical history, we concluded that she had hypersensitivity to ondansetron. Alimta/ cisplatin are unlikely causes for her hypersensitivity symptoms because her reaction occurred 7 days after the infusion, and she tolerated subsequent doses without any adverse events. We performed palonosetron prick, intradermal test (IDT), and intravenous provocative test 3 weeks after her initial reaction. Prick tests to palonosetron at 0.05 mg/mL (undiluted concentration) and IDTs at 0.0005 mg/mL and 0.005 mg/mL were all negative. Appropriate responses of prick test and IDTs to both the negative saline control and positive histamine control were seen. We performed skin prick test with palonosetron at 0.05 mg/mL and IDTs at 0.05 mg/mL, 0.005 mg/mL, and 0.0005 mg/mL on six healthy controls with no known palonosetron allergy. All six control subjects had positive IDT at

0.05 mg/mL, suggesting that it is an irritating skin testing concentration. She then underwent provocative test with 0.25 mg of palonosetron intravenously (10% of the target dose). She tolerated this, and a subsequent 2.25 mg of palonosetron was given intravenously without any adverse events. The patient completed two additional cycles of Alimta/cisplatin with palonosetron without any hypersensitivity reactions. Hypersensitivity to ondansetron is rare but can be fatal.4,6-8 Allergy to 5-HT3-RAs has been considered as a class effect, until two recent reports showed the safe use of granisetron in patients with ondansetron.5,6 It has been speculated that the indole ring shared by ondansetron and tropisetron (but not granisetron) act as the drug epitope and is responsible for their cross-reactivity.2 Palonosetron does not have the indole ring and, instead, has a fused tricyclic ring attached to a quinuclidine moiety.3 In conclusion, skin testing can be performed with nonirritating skin testing concentrations in patients with suspected hypersensitivity to 5-HT3-RAs (Table I).4-6,9 There are safe alternative 5-HT3-RAs (ie, granisetron and palonosetron) for patients with ondansetron hypersensitivity and positive skin testing (Table II). This is particularly relevant when newer 5-HT3-RA palonosetron has been shown to be more effective than ondansetron in preventing acute and delayed chemotherapy-induced nausea and vomiting.10,11 Department of Rheumatology, Immunology and Allergy, Harvard Medical School/ Massachusetts General Hospital, Boston, Mass No funding was received for this work.
