Pediatric Amoxicillin Dosing for Otitis Media

Pediatric Amoxicillin Dosing for Otitis Media

Otitis media, or middle ear infection, is a common childhood ailment often treated with amoxicillin. The appropriate dosage depends on several factors, including the child's age, weight, and the severity of the infection. Here's a general guide to pediatric amoxicillin dosing for otitis media:

Standard Dosing:

? 80-90 mg/kg/day divided into two doses (given every 12 hours)

? This higher dose is recommended to overcome resistant strains of bacteria

Age-based Recommendations:

? Infants < 3 months: Typically not treated with oral antibiotics; require evaluation

? 3 months to 12 years: 80-90 mg/kg/day divided into two doses

? > 12 years: Adult dosing, typically 500 mg twice daily or 875 mg twice daily

Weight-based Dosing Examples:

? 5-7 kg: 125 mg twice daily

? 8-11 kg: 250 mg twice daily

? 12-19 kg: 375 mg twice daily

? 20-28 kg: 500 mg twice daily

? 29-39 kg: 750 mg twice daily

? 鈮?40 kg: Adult dose (875 mg twice daily)

Duration of Treatment:

? Typically 5-10 days, depending on severity and response

? Shorter courses (5-7 days) may be appropriate for uncomplicated cases in children 鈮?2 years

Special Considerations:

? Severe infections may require higher doses or longer treatment duration

? Children with recurrent infections or those in areas with high antibiotic resistance may need different regimens

Formulations:

? Available as liquid suspension, chewable tablets, or regular tablets

? Concentration of liquid suspension varies (125 mg/5 mL, 200 mg/5 mL, 250 mg/5 mL, 400 mg/5 mL)

Administration Tips:

? Can be given with or without food

? If using liquid suspension, shake well before each use

? Use a proper measuring device for accurate dosing

Monitoring:

? Observe for improvement in symptoms within 48-72 hours

? Follow up if symptoms worsen or don't improve

Potential Side Effects:

? Diarrhea, nausea, vomiting

? Rash (may indicate allergy - seek medical attention)

Precautions:

? Verify no penicillin allergy before administering

? Adjust dosage for children with kidney impairment

It's crucial to note that these are general guidelines, and the specific dosage should always be determined by a healthcare provider based on the individual child's needs and medical history. Never adjust the dose or duration without consulting a healthcare professional. Always complete the full course of antibiotics as prescribed, even if symptoms improve before the medication is finished.

Remember, overuse of antibiotics can lead to resistance, so they should only be used when necessary and as directed by a healthcare provider. In some cases of otitis media, especially in older children with mild symptoms, a ”wait-and-see” approach might be recommended before starting antibiotics.
