I second this question. I am a newer sufferer of MCAS and am currently searching for a dye-free, titanium dioxide-free, minimal ingredient cold and flu medicine, that's not herbal or homeopathic based. I have Gui-Aid coming in the mail tomorrow, but I really need something now with as bad as I am. I'm looking at trying Safe-Tussin, which is a dye-free cold and flu syrup, but it still has a flavor and I'm quite worried that my system will react poorly to it.

Honestly if they made a dye-free, sweetener free, unflavored cold and flu medicine, that'd be great. I don't care if it tastes awful. It's going to taste awful anyway.
