Hi Joe!
Sorry to hear about your rashy stuff! Your neuro may have you pretreat with Benadryl and tylenol before infusion now.

I have had pinpoint itching during infusion for awhile now. It doesn't get worse, there's no physical evidence, no further signs or symptoms involved. I am trying to get to the bottom of it during infusion. I noticed that the mixture in the IV bag seemed to be separating towards the end of infusion , so last month we rotated the bag a few times and no itchies.

Have you posted this on the Tysabri thread? Maybe you will get a response from someone who is now or has been on Ty and has had these symptoms.

I hope it works out for you! Please let us know how it comes out!
