Paracetamol is the active ingredient in most Calpol products and the amount of paracetamol differs from product to product.
Typically, the Calpol Infant products, which are suitable for children aged 2 months and older, contain 120mg of paracetamol per 5ml of medicine.
The Calpol Six Plus range typically contains 250ml of paracetamol per 5ml of medicine or 250mg of paracetamol in each Fastmelt tablet.
Of course, this may differ from product to product or if the manufacturer of Calpol makes any changes, so be sure to speak to your doctor or pharmacist or read the patient information leaflet that comes with Calpol products carefully before you give any to your child.
