Amoxicillin dosage depends heavily on factors like age, weight, and the specific infection being treated. Always follow your doctor’s prescription. Never adjust the dose yourself.
Adult Dosage (Generally 12 years and older)
A common adult dose is 500 mg every 8 hours, or 250 mg every 12 hours. However, your doctor might prescribe a higher or lower dose depending on your condition’s severity. The treatment duration typically ranges from 5 to 14 days. Severe infections may necessitate intravenous administration.
Pediatric Dosage
Children’s amoxicillin dosage is calculated based on weight, usually in milligrams per kilogram (mg/kg). A typical dose for children is 20-40 mg/kg per day, administered in divided doses. For example, a child weighing 20 kg might receive 400 mg per day, divided into two doses of 200 mg each. Always consult a pediatrician for precise instructions.

Important Considerations
Allergic reactions: Amoxicillin is a penicillin-based antibiotic. Inform your doctor about any penicillin allergies before taking it. Kidney function: Dose adjustments may be necessary for patients with impaired kidney function. Pregnancy and breastfeeding: Discuss amoxicillin use with your doctor if you are pregnant or breastfeeding.
Seek immediate medical attention if you experience severe allergic reactions such as hives, swelling, or difficulty breathing.
