Zantac dosing

[Anonymous]

Hi all, my 9 weeks old son is on Zantac, he weighs 6.2 kilos now and takes 3xtimes a day 0.66 mls. Not sure if this is still the right dosage for him, as we are out of country for a month and doctors here don´t even prescribe Zantac to babies. He seems a bit worse now so just wondered it is because we need to top up his medicine??? Looking at internet but little confused. Any help please. Thank you sooo much.

maximum dose for zantac by weight is 10mgs per kilo, so

6.2 x 10 = 62

so that’s 62mgs total for the day of zantac

the zantac is a liquid, so it’s in mls rather than mgs.

look at your bottle it should read: 15mgs/ml

so then you take the 62 & divide by 15 = 4.1mls, total for the day of zantac

you can then split 4.1mls into two doses

and the doses can be ‘uneven’ with a higher portion given at the worst time, usually the evening/night

here is where I learned about proper zantac dosing:
