Thanks for writing to health care magic.
I can understand your concern.
I did not understand why a child should loose speech after antimalarial.Hearing loss
is a known complication of some antimalarials.
Did your doctors say that your child had any other problem like meningitis?
You should consult ENT Specialist
for further action.
Continue to ask further queries as required.
Hope this helps.
