What is a maximum dose of paracetamol one can take?

Depending on your age, and wheather or not you have a history of liver/gastric problems means this can not be a personal answer. However, for an adult, with no history of gastric/liver problems OR history of allergic reactions to paracetamol or ibuprofen, you can take up to 1g of paracetamol, and 400mg of ibuprofen.
