How does Amoxicillin treat ear infections?

Amoxicillin combats ear infections by targeting the bacteria responsible for most cases, primarily Streptococcus pneumoniae and Haemophilus influenzae. It works by interfering with the bacteria’s ability to build cell walls, a crucial structure for their survival. This disruption leads to bacterial cell death, reducing the infection.

The medication reaches the middle ear through the bloodstream after oral administration. Absorption rates vary depending on factors such as age and overall health. Sufficient concentrations in the middle ear fluid are necessary for effective treatment.

Factor Impact on Amoxicillin Effectiveness
Dosage Correct dosage ensures sufficient drug levels to fight the infection.
Duration of Treatment A full course of Amoxicillin is vital, even if symptoms improve early, to prevent recurrence.
Bacterial Resistance Overuse of antibiotics can lead to resistance, reducing Amoxicillin’s effectiveness.

While generally safe and effective, Amoxicillin can cause side effects, including diarrhea and allergic reactions. Always consult a doctor before using any medication, especially for children.
