Amoxicillin Pediatric & Adult Antibiotics Dosage and Calculation

Dosage for Children: Determining the appropriate dosage of amoxicillin for pediatric patients requires careful consideration of factors such as age, weight, and the severity of the infection. The American Academy of Pediatrics (AAP) provides guidelines for pediatric amoxicillin dosing based on weight:

- For children weighing less than 40 kg (88 lbs), the recommended dosage is 25 mg/kg/day divided into two or three doses.
- For more severe infections or those caused by less susceptible organisms, the dosage may be increased to 45 mg/kg/day divided into two or three doses.

It's crucial to accurately calculate the child's weight and adjust the dosage accordingly to prevent under or overdosing. Additionally, educating parents or caregivers on proper administration techniques and ensuring compliance with the prescribed regimen is essential for successful treatment outcomes.

Dosage for Adults: For adults, teenagers, and children weighing 40kg or more - the standard dosage of amoxicillin for most dental infections is typically 500 mg three times daily or 875 mg twice daily, depending on the severity of the infection and the patient's medical history. The duration of treatment usually ranges from 5 to 7 days. However, in cases of severe infections or complications, a higher dosage or extended duration may be warranted.
