Omeprazole is a proton pump inhibitor that aids in decreasing gastric acidity. However, it is not recommended for babies below one year. When babies suffer from gastroesophageal reflux disease (GERD), the pediatrician may suggest specific feeding changes like feeding in an upright position, avoiding overfeeding, and burping. Under severe conditions, the doctor may suggest Omeprazole to relieve the baby from symptoms.
