What dosage of amoxicillin for my 23 pound 9 month old?

Varies: The dose of Amoxil (amoxicillin) depends on the infection being treated. For most things it is ~45mg/kg divided twice a day.

My son is ten and weighs 130 lbs. He was prescribed Amoxicillin 400 mg/5 ml suspension. 2 1/2 teaspoons once daily. Is this the correct dosage?

My son is ten and weighs 130 lbs.  He was prescribed Amoxicillin 400 mg/5 ml suspension.  2 1/2 teaspoons once daily.  Is this the correct dosage?

He should be getting between 800 and 1600 mg per dose twice a day. Perhaps the physician meant to write for 1,000 mg twice a day and the RX was mistyped. ...Read more
