The maximum amount of paracetamol that an adult can safely take in 24 hours is generally 4 grams , which is equivalent to eight 500mg tablets or four 1g tablets if prescribed by a doctor. The usual dosing is one or two 500mg tablets every 4 to 6 hours, with no more than 4 doses per day, and it is important to wait at least 4 hours between doses. Taking more than this recommended dose can cause serious liver damage and can be fatal. If weighing less than 50 kg, or if unsure about the dose, it is advised to check with a doctor or pharmacist. It is also important to avoid taking multiple medicines containing paracetamol simultaneously and to follow the instructions on the medicine packaging carefully. Summary:

• Maximum: 4 grams (8 tablets of 500mg) per 24 hours
• Usual dose: 1-2 tablets (500mg each) every 4 to 6 hours
• Wait at least 4 hours between doses
• Do not exceed 8 tablets in 24 hours
• Check with a doctor if under 50kg or if uncertain

Taking more than this limit can cause liver damage and requires urgent medical attention. References from NHS, HealthDirect, Drugs.com, and other medical sources confirm these guidelines.
