Augmentin (amoxicillin with clavulanate) is a common antibiotic doctors prescribe for bacterial infections like sinusitis, ear infections, bronchitis, skin infections, and some bite wounds. It pairs amoxicillin — which kills bacteria — with clavulanate, which helps stop bacteria that make certain enzymes from breaking the drug down. That makes Augmentin useful when plain amoxicillin would fail.
Doctors pick Augmentin when they suspect bacteria that resist simple penicillin drugs. For example, if you have a bad sinus infection that didn’t improve or an ear infection in a child, Augmentin often works better. It’s also used after animal or human bites, and for many skin infections.
But antibiotics don’t help viruses like colds or most sore throats. If your doctor says you don’t need antibiotics, trust that advice — using them when not needed fuels resistance and can cause side effects.
Take Augmentin with food to reduce stomach upset. It comes in tablets, chewables, and liquid. Follow the exact dose and time schedule your prescriber gives — don’t skip doses and finish the whole course even if you feel better. Stopping early can let the infection return stronger.
Typical adult doses vary by infection severity and formulation. For children, liquid doses are weight-based. Never give adult tablets to a child unless a provider says it’s okay. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one — then skip the missed dose and continue.
Common side effects include nausea, diarrhea, and mild rash. If you get severe belly pain, yellowing skin or eyes, dark urine, or a severe allergic reaction (swelling, trouble breathing, hives), stop the drug and get urgent care. People with a penicillin allergy should not take Augmentin — tell your provider about any past reactions.
Augmentin can interact with other medicines like methotrexate or certain blood thinners. It may affect gut flora and reduce effectiveness of oral contraceptives in rare cases — consider backup birth control if you’re worried. If you have liver disease, kidney problems, or are pregnant or breastfeeding, talk to your clinician before starting Augmentin.
Want to avoid trouble? Use antibiotics only when prescribed, follow instructions, and report side effects. If symptoms don’t improve in 48–72 hours or you get worse, contact your clinician — sometimes a different antibiotic or tests are needed.
