Vomiting in children with fever is mostly due to the phenomenon of solid heat in the lungs and stomach. You can take pediatric cold and flu granules orally, which can treat and relieve the symptoms of fever caused by common cold and influenza. It can be combined with Chinese medicines, such as Blue Scutellaria Oral Liquid and Shuang Huang Lian Oral Liquid, which can clear heat and detoxify the toxins. It can be combined with domperidone suspension, which can promote gastrointestinal peristalsis and improve the symptoms of vomiting. If the child’s body temperature exceeds 38.5℃, you can take oral antipyretic and analgesic drugs such as ibuprofen suspension, or acetaminophen suspension, which can play a fast role in reducing fever. If the child vomits frequently, is depressed, or even has convulsions, he or she needs to go to the emergency department and pediatrician, and is usually given intravenous fluids for symptomatic treatment, and if the condition is serious, hospitalization is recommended.
