Indications and Uses

• The U.S. Food and Drug Administration has approved amoxicillin for treating infections of the ear, nose, genitals, respiratory tract, skin, throat and urinary tract. Amoxicillin also has an indication for treating stomach ulcers caused by Helicobacter pylori. According to a Medline Plus factsheet, amoxicillin also has uses for preventing anthrax and chlamydia infections.
  
  

Dosing

• The dose and duration of amoxicillin therapy depends on the infection and the individual being treated. For instance, an adult with a severe throat infection may receive 875 mg of amoxicillin every 12 hours for two weeks, while a newborn with a mild skin infection might receive 25 mg of amoxicillin per kilogram of body weight each day for a few days. A dosing chart that is the same for all amoxicillin products appears in the prescribing information for Amoxil.
