Amoxicillin is an antibiotic belonging to the aminopenicillin class of the penicillin family. It is widely used to treat various bacterial infections, including middle ear infections, strep throat, pneumonia, skin infections, urinary tract infections, Lyme disease, and infections caused by Helicobacter pylori. It works by interfering with the synthesis of the bacterial cell wall, which leads to the death of the bacteria. Amoxicillin can be taken orally as capsules, tablets, chewable tablets, or suspensions. It is usually taken two or three times a day, sometimes with food to reduce stomach upset. It is important to take the full course of amoxicillin as prescribed to avoid antibiotic resistance or incomplete treatment. Common side effects include nausea and rash, and it should not be used by individuals allergic to penicillin. Amoxicillin may also be combined with clavulanic acid, which inhibits bacterial enzymes that can destroy amoxicillin, increasing its effectiveness. It is one of the most commonly prescribed antibiotics globally and is considered safe during pregnancy and breastfeeding. However, the dose may require adjustment in people with kidney problems.
