Hi, hope someone on here can help enlighten me. I really don't understand the difference in effects between the two. When would you give one over the other? I'm talking about in an 8mo with a high temperature and a nasty cold. It seems some people use them interchangeably, i.e. One in the morning then the other for the next dose! My mum suggested giving both plus a cough syrup and drops for blocked nose throughout the day (spacing doses according to packet instructions). It just seems like an awful lot of medication to me.
