Hi everyone. I’m new to this site, however have been reading for months. I have a 6 month old son, 4.5 months adjusted. We have been fighting with severe reflux for what seems like forever. I was just wondering for those of you that have used erythromycin, did it lose it’s effectiveness after so long? Also where can I seek dosing info… My pediatric gi is not easy to get answers from. My son is about 19 lbs and takes .75 ml 3x per day along with 15mg of Prevacid. Even with the erythromycin his spitting up lately seems out of control! I’m just at a loss at what to do.
