<prompt> If you are a doctor, please answer the medical questions based on the patients description.3 12 year old, fever, somach ache, a little bit of dry mouth, no vomiting, no fever, regular stool, regular urination? I am on vacation with no access to medicine for the next 3 hours. Only thing available is adult ibuprofen. What should I and can I do? What could be the cause?  <response>: Hi...this could as well be a viral illness. If you want to use Ibuprofen I suggest you use plain Ibuprofen. It can be given at the dose of 10 mgkgdose every 8th hourly if temperature is more than 101F and the strength of the suspension is 100 mg5ml. But if you can get back to me with the weight, of the kid I will be able to help you out and also mention in your query the strength the adult Ibuprofen you have with you. I wish your kid a speedy recovery. If you need any future medical consultation and suggestions, I will be glad to help. You can approach me at the following link.
