I took Claritan with my chemo infusion/Neulasta injections, based on a recommendation from the chemo nurse. I stopped, after a few infusions, since I did not seem to be having any allergy-like side effects. Maybe I should have kept with it. I tell people chemo is somewhat akin to catching a short-course of the flu every three weeks. Also, the Neulasta can cause bone throbbing. They recommended ibuprofen for that. However, my bone throbbing was minor and rarely bothered me. Take care.
