My 9 years old daughter had lower lobe pneumonia ten
Needs to see her doctor...
Digene syrup can be used to control gastritis. But in my opinion, she should be seen by her doctor for evaluation. The symptoms of fever, vomiting, abdominal pain (gastritis) and loose stools suggest gastroenteritis. It may or may not be related to her medications used recently. A stool tests is recommended. Specific treatment will follow based on examination and test results.
Hope this helps. Let me know if you need clarifications.
