has anyone experienced problems from the dye found in most of our antibiotics? Our rx of zithro (tablets) has red dye #40. I posted earlier saying that it has been 5 days now that my dd has been on it. I feel like it is spiking her tics - everyone thinks I am over reacting, but it is a real concern for me. I can not say positively that she reacts to it but it is a motherly hunch I guess... Has anyone experienced this?
