My baby is receiving Prevacid but it doesn't seem to be effective?

If your baby is not responding well to Prevacid, it could be due to an allergy rather than an intolerance to lactose. You can inquire about alternative formulas such as Nutramigen, Pregestimil, or Puramino at your pharmacy. It's also a good idea to consult with your pharmacist about adjusting the dosage of Prevacid or exploring other options like ranitidine. Your pharmacist will be able to provide the best advice based on your specific situation. Don't hesitate to ask if you have any further questions.
