What to do if I had an allergic reaction to oxaliplatin chemo?

Ask. Ask your oncologist about your options. Depending on the malignancy, oxaliplatin may be your best option even after having a reaction. An Allergist can help to evaluate the reaction, and depending on its nature, suggest an effective premedication regimen or even assist with a desensitization procedure (basically fooling the immune system into accepting the drug).
