Co-amoxiclav, also known as amoxicillin/clavulanic acid, is a combination antibiotic medication used to treat various bacterial infections. It contains two active ingredients: amoxicillin, a penicillin antibiotic that kills bacteria, and clavulanic acid, which inhibits a bacterial enzyme that makes amoxicillin less effective. This combination makes co-amoxiclav effective against a broader range of bacteria that might resist amoxicillin alone. It is prescribed for infections such as sinus infections, respiratory infections (like bronchitis and pneumonia), urinary tract infections, skin infections, joint infections, dental infections, and certain other bacterial infections. Co-amoxiclav can be given as tablets, oral liquid, or injection. Common side effects include diarrhea, vomiting, and allergic reactions. It should be used with caution in people with penicillin allergy, liver or kidney problems, and during pregnancy or breastfeeding with medical advice. The full course of treatment should be completed even if symptoms improve earlier. Co-amoxiclav is known under brand names like Augmentin and is considered a critically important medication in human medicine worldwide.
