[/INST] HiHe may be having diarrhoea from penclav.  You can consult your specialist again and ask him to change antibiotics,  usually Oflox or Levoflox is prescribed in such cases,  duration of treatment remains sameTake care of the allergy if any,  also in case of hearing loss,  better to get an audiometry done to be on safer side </s>
