Hallow Dear, If you are having acute tonsillitis, you have to take antibiotics to control the infection. You have been prescribed Augmentin. Augmentin contains a combination of amoxicillin and clavulanate potassium. Amoxicillin is an antibiotic in a group of drugs called penicillins. Amoxicillin fights bacteria in the body. Clavulanate potassium is a form of clavulanic acid, which is similar to penicillin. Clavulanate potassium fights bacteria that is often resistant to penicillins and other antibiotics. Hence it is safe to take in pregnancy. For pain and fever, I would advise you to take plain Paracetomol. Some researches have found that any NSAID like Ibuprofen may lead to miscarriage of pregnancy. I hope this helps you. Dr. Nishikant Shrotri
