Re: metronidazole prescribing. Per your question:
>At what age/weight would a physician prescribe Flagyl for a child?
At present there are no FDA approved pediatric indications that I
know of. However, The Harriet Lane Handbook(Pediatric) lists doses
varying from 15-35 mg/kg/24 hrs depending on the source of infection.
Nelson's Pocket Book of Pediatric Antimicrobial Therapy lists a
dose of 15 mg/kg/24 hrs(dividied q 8 hrs) for 5 days for therapy of giardiasis.
So to answer your question, although not FDA approved, it is
commonly used in pediatric NICU's and PICU's at almost all ages.
