@IdealForehead Did you ever start using a topical loradatine?
One thing I find confusing is that the study re: cetirizine degradation says that it can react with low Contact of cetirizine should be avoided with alcohols having a molecular weight less than 100, such as methanol, ethanol, isopropanol and glycerine. But I have seen a lot of examples of cetirizine being used in oral solutions with glycerine and PG. So I don't really know what to think. I have gone back to using a vehicle with a low concentration of ethanol and seems to be working okay.
