❓ Frequently Asked Questions About Amoxicillin for Children

How much amoxicillin should I give my child?
The standard amoxicillin pediatric dose is 20-50 mg per kg of body weight per day, divided into 2-3 doses. For most infections: 40 mg/kg/day divided every 8-12 hours. For strep throat: 50 mg/kg/day once daily (max 1000 mg). Use our calculator for exact weight-based dosing.
What is the amoxicillin dose for ear infections?
For ear infections (acute otitis media), the recommended dose is 85 mg/kg/day divided every 12 hours for 10 days. This higher dose is needed because amoxicillin penetrates the middle ear less effectively. Maximum daily dose is 2000-3000 mg depending on severity.
How do I calculate amoxicillin dose by weight?
Formula: Weight (kg) × Dose (mg/kg) ÷ Number of doses. Example: 15 kg child, standard dose 40 mg/kg/day divided twice daily = 15 × 40 = 600 mg total per day ÷ 2 = 300 mg per dose. Our calculator does this instantly.
How many days should a child take amoxicillin?
Ear infections: 7-10 days. Strep throat: 10 days (full course essential to prevent rheumatic fever). Pneumonia: 7-10 days. Sinusitis: 10-14 days. Always complete the full prescribed course, even if symptoms improve.
Can I mix amoxicillin with food or juice?
Yes! Amoxicillin can be taken with or without food. Mixing with a small amount of applesauce, yogurt, or juice can help children take it. Give the full mixture immediately - don't save for later. Shake suspension well before each use.
What if I miss a dose of amoxicillin?
If you miss a dose, give it as soon as you remember. If it's almost time for the next dose, skip the missed dose and continue regular schedule. NEVER double up doses. Complete the full course to prevent antibiotic resistance.
