My 4-month-old son is taking 7.5 MG of Prevacid twice a day and 1.8 ML of Zantac twice a day. Does that mean that each dose needs to be 12 hours apart? Or is there a little wiggle room there? I’m trying to avoid having to wake him up in the middle of the night to give him a dose (since I’ve been reading that the Zantac and Prevacid need to be given 4 hours apart for the Prevacid to work effectively). If the doses need to be 12 hours apart, it’s going to be very tough to get the meds in. Thanks.
