Marci-kids dose for Zantac?

[Anonymous]

I just need to reference a dosing schedule when I find out how much he weighs but I can’t find one for Zantac on marci-kids. Also, I have a hard time converting kilos, lbs and mls Any help would be greatly appreciated! I read Laura’s groupie info but still am confused about the Zantac

The max daily Zantac dose is 10mg/kg (split up however you want over a 24 hour span). The range is 5-10 mg/mg.

So, it depends on your Zantac. The typical formulation (it says on the bottle) is 15mg/mL.

So, to help w/ your range we need your ds’s weight :).

ok, just weighed him. he is 11lbs. I’m sure doc will start him on .5ml twice a day. So what ml dose should he have? thank you!

Zantac dosing- my/other’s question (has axid & pepcid dose,
too):

https://www.infantreflux.org/forum/forum_posts.asp?TID=8288&PN=1

conversion chart: http://www.sfca.co.uk/match/kilolbs.htm

ok so 11lbs is 5kgs

the maximum zantac does by weight is 10mgs per kilo

so 10 x 5 = 50 mgs total of zantac for the day

your zantac is in liquid form, so look at the bottle & it should read 15mgs/ml

that means that for every 1ml of liquid you give of zantac, your baby is getting 15mgs of the medicine

so, since your baby can have 50mgs of zantac,

divide by 15 to get how much liquid to give

so 50 divided by 15 = 3.3

that’s 3.3 mls total for the day of zantac

divide into two doses and the doses can be ‘uneven’-

so if night time or evening is ‘worse’ then give a higher portion of the meds at that time

example: 1.3 + 2 mls = 3.3
1.5 + 1.8 = 3.3
etc

Thank you sooo much!

[Anonymous]

oh, someone just sent me an email from marcikids and he said 25mg 3 times a day which would be 75mg. Isn’t that too much? the max is 50mg right? What is that in mls?

[hellbennt]

try the 50 (the calculations I just did for you)- you cannot really over-do it as far as I know…if after a few days the 50 isn’t doing it- I’ll figure out the 75, lol. In the meantime, get to a ped Gi or family practitioner or someone who will prescribe a PPI for your baby

[Anonymous]

Thanks Laura for doing the conversions… I was just logging on to do them & see you already responded :).

[Anonymous]

thanks again! shouldn’t i see how the zantac works first? my ped was reluctant to give my baby the zantac. I had to push him. he will surely give me a hard time about a PPI.

[hellbennt]

if your baby constantly needs his zantac dose increased w/ every weight-gain and then eventually it doesn’t seem to be helping (as much) anymore, then it’s time to ‘move on’ to a PPI.

ps: is your screen name have to do w/ WSP 🙂 ?

[Anonymous]

YES!!!
How do you quote here?

[Anonymous]

I would definitely say ‘ditto’ to what Laura suggested… I would try the Zantac but if it doesn’t seem to be working & helping your ds find FULL reflux relief then I would move onto a PPI.

Good luck!
