Eloxatin is Oxaliplatin. I WOULD NOT recommend popsicles or ice chips with Oxaliplatin. It has a strange side effects that makes most people extremely sensitive to cold. He will need to be careful about handling cold things (like grabbing a frozen dinner from the freezer or a carton of milk from the 'fridge). Chances are, he'll want to drink room temperature liquids.
From what I understand, this is a very common side effect. So don't jump into the ice chips or popsicles until you know for sure how he'll respond.
Do make sure he drinks lots of water though.
