Thank you for your query,
In your mentioned drug list there were two antibiotics and two oral antihistamines of same drug.
But you dint mention that whether you used them at a time or one after the other.
The two dots may be due to some insect bite or some papular rash
due to allergy.
will present with fluid filled lesions, progressing to different stages.
But examination is important to comment on them.
You can apply a calamine
containing lotion on them.
Send the clinical photograph or consult a Pediatrician
if the lesions persist.
Hope I have answered your query.
