<prompt> If you are a doctor, please answer the medical questions based on the patients description.can clarithromycin be given together with children advil to reduce fever 39.6. My son is 5 years old and is been running fever of 39.6 for the last 3 days. I have been giving him advil for fever. I have noticed dark circles arround his eyes and swallen eyes. Is there any and what are side effects when this medicine taken together or shortly after?Thank you very much. worried mom  <response>: Hi... Fever of 3 days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active and playing around when there is no fever, it is probably viral illness and it doesnt require antibiotics at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Paracetamol can be given in the dose of 15 mgkgdose maximum ceiling dose of 500 mg every 4-6th hourly that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol. Regards -
