Rasonix JR 10 mg is a pediatric formulation of rabeprazole, a proton pump inhibitor (PPI) used to treat conditions associated with excessive stomach acid production in children, such as gastroesophageal reflux disease (GERD) and peptic ulcers. By effectively inhibiting the proton pump in the stomach lining, Rasonix JR reduces gastric acid secretion, helping to alleviate symptoms like heartburn and acid reflux, and promoting healing of the esophagus and stomach lining. This medication is typically administered once daily, and it is important for caregivers to follow the healthcare provider's instructions regarding dosage and duration of treatment to ensure safe and effective management of the child's condition while minimizing potential side effects.
