If once given after how many hours should the next dosage of Mucolite and Maxtra be given? Also can Mucolite and Maxtra be given together?

A. The medicines can be given together but with the gap of 10 to 15 minutes because when you give them back to back the child can vomit and a minimum gap is eight hours because these medicines are generally meant to be given three times in the day so minimum gap that you maintain his eight hours
