Sounds like a reaction. You need to notify your doctor. Take some Benadryl in the meantime (generic is fine). Go to the ER if it does not improve or you feel any throat swelling or dizziness.

If you are OK to have another infusion, they will need to premedicate to prevent another allergic reaction. You need to take it seriously, as each exposure can cause a more severe reaction.

its not a common allergic reaction but it certainly sounds like somethings amiss. curious did they premedicate you before each of your infusions? so infusion 2 and infusion 3 have caused this major swelling? you might also try calling the infusion center staff as well and get them on board to this reaction.

and Jan is absolutely right, the most severe reaction would be anaphylactic shock and you don't want to experience that.  

Before infusions they give 2 Tylenol and Benadryl..My first infusion I was sick and had a major headache but after the second infusion had major swelling and sick for 2 days as well as the third..Thanks for your reply��
