It may also be used in combination with other medications to treat Helicobacter pylori (H. pylori) infection and duodenal ulcers.

💊 Amoxicillin Dosage and Administration

Amoxicillin is available in capsules, tablets, chewable tablets, and oral suspension forms. The dosage depends on the type and severity of the infection, as well as the patient’s age and weight.

Amoxicillin kills bacteria by interfering with their cell wall synthesis, ultimately leading to cell death. It is effective only against bacterial infections and does not work for viral infections like the flu or common cold.
