My daughter was put on Bethenecol and Prevacid when she was 6 weeks old for her GERD. The doctor, Dr. Hunt, said that the Bethenecol would make her stomach empty faster which would cause her to spit up less, and would enable her to gain weight. The prevacid would neutralize the acid to prevent the pain associated with GERD. Both medications seemed to work very well. She spit up less, gained weight, and was more agreeable and less fussy. We were able to stop both medications by the time she was 6 months old. She didn't seem to have any side effects associated with either of the medications. Good luck. I know it is frustrating.
