If acid reflux and vomiting in children is caused by food accumulation or indigestion, you can choose to take probiotic drugs and drugs to inhibit the secretion of gastric acid for treatment under the guidance of doctors. If it is caused by bacterial infection, you can take antibacterial drugs. 1. Probiotics: Most children will experience acid reflux or vomiting when there is a buildup of food or indigestion in the stomach to help reduce the pressure on the gastrointestinal tract. Probiotics such as Bifidobacterium quadruple vivax tablets can be used under doctor’s supervision to regulate the intestinal flora and relieve the symptoms. 2. Drugs to inhibit gastric acid: After children have acid reflux symptoms, they can take drugs to inhibit gastric acid secretion under the guidance of a doctor to effectively reduce the symptoms of acid reflux, such as omeprazole, ranitidine and so on, to help protect the mucous membrane on the surface of the digestive system. 3. Bacteriostatic drugs: Some children with acid reflux and vomiting symptoms may also be triggered by acute bacterial infections in the gastrointestinal tract. You can take antibacterial drugs such as cefixime under the guidance of a doctor to effectively treat the infection in the gastrointestinal tract and help relieve the discomfort. Children with acid reflux and vomiting symptoms are advised to seek prompt medical attention.
