Thanks for sharing your concern.
It is more likely a viral rash
though the possibility of an allergic reaction
is still there.
Unfortunately there is no certain way to know .
The good news is that both types of rashes are very common in kids & generally last a few days .
is likely to work in allergy
but not in viral rash. Is the dose right ?
Can easily wait 3-4 days for rashes to improve if she remains otherwise ok.
Hope you find the information useful.
