While Augmentin (amoxicillin/clavulanic acid) is a very effective antibiotic, it only works against bacterial infections and will not help if your sore throat is viral. Because your pain is concentrated on one side and has not improved with Combiflam (ibuprofen/paracetamol), it is very important to have a doctor physically examine your throat. This helps rule out localized complications, like a tonsillar abscess, before starting antibiotics. Please stay well-hydrated, continue gentle warm gargles, and consult a healthcare professional in person to receive the correct diagnosis and prescription.
