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.
