The question is whether there is an interaction between Reactin (cetirizine) and Advil Cold and Sinus (Ibuprofen and pseudoephedrine). There is no problem combining the 2 products. There are several formulations of Advil Cold and Sinus. Make sure yours does not contain antihistamines, as in the "plus" or "night" formulations. Thanks for your question. Élise Grondin.
