Adult chickenpox. doing better but noticed pus (not clear fluid) on 2 facial pox. will see doc irl but wanted opinion on best antibiotic protocol?

Not always pus: The fluid within chickenpox blisters can turn a straw colored/grayish over time which is not always an infection. The blisters can become infected . The proper meds to use at that point would depend on the sensitivity pattern of germs common to that local area. No one answer would be right for all regions. The local docs would have that information to use as a guide.
