Your dentist will determine the correct amoxicillin dosage for your specific tooth infection. However, common adult dosages range from 500mg to 875mg, taken every 8 or 12 hours. Children’s dosages are significantly lower and depend on weight and age. Always follow your dentist’s or doctor’s prescription instructions precisely.
Factors Affecting Dosage
- Severity of the Infection: More severe infections may require higher dosages or a longer treatment duration. Patient’s Weight and Age: Dosage is adjusted based on these factors to ensure safety and efficacy. Other Medical Conditions: Pre-existing health issues may influence the dosage and the choice of antibiotic. Allergies: Amoxicillin is not suitable for those with penicillin allergies.
Common Dosage Regimens (Always follow your prescription)
Adults: 500mg every 8 hours, or 875mg every 12 hours. Children: Dosage varies greatly; your pediatrician will provide precise instructions based on your child’s weight and age.
Remember: Never alter your prescribed dosage without consulting your doctor or dentist. Complete the entire course of antibiotics, even if symptoms improve, to prevent recurrence of the infection. Contact your healthcare provider immediately if you experience any adverse reactions such as rash, swelling, or difficulty breathing.
Missed Dose
If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. Do not double the dose to catch up.
