Calpol Peppermint Flavour Oral Drop is used to manage acute fever, painful teething, and post-vaccination discomfort associated with pediatric common colds, influenza, and childhood minor illnesses. It contains Paracetamol as its primary active ingredient. This medication works by inhibiting prostaglandin synthesis in the brain to safely reduce elevated body temperature and elevate the pain threshold. The drop offers fast-acting relief while remaining gentle on the child's system, so measure the exact dosage as prescribed by your doctor.
