Cepara 250mg Injection is used to treat various bacterial infections such as respiratory tract (lungs) infection, urine infection, blood infection, meningitis (inflammation of the brain and spinal cord), gonorrhoea (sexually transmitted disease), skin, abdominal, bone, and joint infections. It contains Cefoperazone, which works by preventing the formation of bacterial cell covering necessary for their survival by binding to the penicillin-binding proteins (PBPs), thus preventing cross-linking of nascent peptidoglycan and killing the bacteria. It may cause diarrhoea, allergic reactions, abnormal liver function tests, and anaemia (low number of red blood cells). Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
