into investigating the true dose for obese people.
It occurred to my child so many times. Doctors love to prescribe based

This under dose will easily create virus and bacteria that is immune
to the antibiotics or antiviral because insufficient dose is
administered to kill all the antigens.
I kept on arguing that the antibiotics is effective because his fever
subside but the rate is so slow that the bacteria has time to mutate
and adjust to the antibiotics.

Experienced doctors will prescribe more than this dose. I met one case
where he prescribed 3 weeks of a strong antibiotic, (because my son
suffer a slight recurrence in fever,) Augmentin, a wide ranging
antibiotic. In Singapore it is routine to get 2 weeks dose of
