hi,
welcome to the forum,
Can understand your concerns.
generalised Rash n a 20 month old baby could be due to
allergic Rash due to use of any truck, Rash due to low
platelet count,
viral fever Rash, measles.
Since, you are already giving some drugs to the child and after which the rush has a beard it seems that we should keep drug reaction as the first possibility.
Inrush due to low platelet count, there's also occurs all over the body, but this is rare in a 20 month old child.
Sometimes, viral fever can also lead to generalize rash. This Rash settles as the fever comes down.
In measles, Rash usually appears over chest and then spreads to whole body. Rash decreases over a period of 5 days.
In my opinion,
drug Rash is the first possibility and you should stop all the medicines. Used can give
hydroxyzine syrup to prevent allergic Rash.
I hope this will help you.
Take care.
Regards,
Dr Deepak Patel
