Hi
Thank you for your query
Any infection in the body can make the child lethargic. It might be a viral infection and that takes its course to resolve. Also if she had any bacterial infection that will be covered by augmentin that she's been taking. If her fever is settling and appetite is on the rise you should not worry. I hope she is also taking some medicine for fever as well. If despite that she does not show signs of improvement then you should consult your pediatrician. But there should be no need to rush to a emergency right now. You can also do some tap water sponging for fever.
Hope that helps
God bless you

Hi
Thanks for your query.
Your child is having sinus infection,continue with medication as prescribed.
It is normal for appetite to decrease after illness.
Give acetaminophen every 6 hourly till fever is above 100F,
Do sponging with tepid water.
Give plenty of fluids,fruit juices.,coconut water,vegetable soup.
Do not force her to eat ,appetite will improve slowly.

If she continues to be lethargic,get him evaluated by pediatrician.
Wishing your baby good health.
God bless.

Hello, thanks for using HCM.
Lost of appetite and being weak are general symptoms that indicate that the body is not well. In her case, they are as a result of the sinus infection (assuming there is no other disease).
Infections of sinuses most often are caused by viruses in which case, the person just has low grade fever and sometimes clear watery nasal discharges. Antibiotics are not prescribed in thess situations. However, it is not uncommon for bacteria to super-imposed thereby causing bacterial sinusitis which could produce high fevers, yellowish or dirty nasal discharges etc. In such situations, antibiotics are prescribed. Common bacteria that infect the sinuses are sensitive to Amoxicillin and clavulanic acid which are the active ingredients of augmentin. Response to antibiotics for common germs usually takes 48 to 72 hours before visible clinical effects are seen such as; decrease in temperature, more active, gain in appetite etc.
For her case, and assuming the doctor saw her, i think for now you should ensure she takes the augmentin in the prescribed dosage, increase her intake especially the fluids ( as she needs more fluid due to increase temperature) and if she's not better within 48hours you should see the ER.
