After a child suffers from gastroenteritis leading to fever, he or she can take cefixime granules, as well as compound flavonoid tablets, oral rehydration salt solution, montelukast, and bifidobacterium triptans capsules. However, you cannot take drugs directly simply by a certain symptom or by considering a certain disease, which may cause side effects. For patients with similar conditions, it is important to go to the emergency room or relevant clinics such as gastroenterology for a comprehensive assessment, and only according to the situation can we determine the specific kind of medication to take. This can be combined with routine blood, electrolyte and stool tests to assess the severity of the condition and then provide targeted treatment. It is also necessary to exclude certain specific triggers, such as cold in the abdomen or eating unhygienic food.
