My 3-year-old child has a fever and keeps vomiting. What medication should I give?

The following are some common causes and recommendations for symptoms of a 3-year-old child experiencing fever accompanied by vomiting: I. Fever Management 1. Physical cooling: If the child's temperature is below 38.5°C, physical cooling methods can be considered, such as applying fever patches or wiping the body with lukewarm water. 2. Medication for fever: If the child's temperature exceeds 38.5°C, antipyretic medications such as acetaminophen or ibuprofen suspension may be administered under a doctor's guidance. II. Vomiting Management 1. Temporary fasting: During episodes of vomiting, it is recommended to temporarily withhold food to allow the child's gastrointestinal tract to rest. However, ensure the child maintains adequate fluid intake to prevent dehydration. 2. Antiemetic medication: If vomiting is severe, antiemetic medications may be administered under a doctor's guidance. III. Treatment Targeting the Underlying Cause 1. Indigestion: If vomiting and fever are caused by indigestion, medications such as domperidone or lactase may be used as directed by a physician. 2. Common cold: If vomiting and fever are caused by a cold due to exposure to cold, medications such as acetaminophen-triprolidine (e.g., Amphenon) or amoxicillin may be used as directed by a physician. 3. Acute gastroenteritis: If vomiting and fever are caused by acute gastroenteritis due to bacterial or viral infection of the gastrointestinal tract, antibiotics or antiviral medications may be used under a doctor's guidance.
