I give Alana hers before her bottle. Have just started Alana on effervesent zantac tablets. They dissolve in water- i put it in the teat and she drinks it like a trooper. It has a salty lemony flavour. We changed because of the alcohol content of the syrup- it is quite high and with the dosages needed they are getting a wee bit much alcohol- no driving
. Don’t know if you can get them in US.
I have on occassion given it during, after, between (usually if i forget or am out and didn’t take it ). I have found it easier to give and more effective prior to meal. Also if they spew, and the zantac is given first maybe there is more of a chance they keep some of the zantac down!
