Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, fever, and inflammation. The recommended dosage of Advil or ibuprofen depends on the condition being treated, the age of the patient, and other factors. It is essential to follow the instructions provided by your doctor or pharmacist, and not exceed the recommended dose to avoid adverse effects.

According to the drug patent watch [1], the recommended dose of Advil for adults and children 12 years and older is 200-400 mg every four to six hours, not to exceed 1200 mg in 24 hours. For children under 12 years, the dose is based on the child's weight and age, and it is advisable to consult a pediatrician before administering Advil.

The USA Today [2] reports that taking too much Advil or ibuprofen can cause stomach ulcers, bleeding, and kidney problems. It is recommended not to exceed the maximum daily dose of 1200 mg of Advil or 3200 mg of ibuprofen per day for adults, and to avoid taking it for more than ten consecutive days without consulting a doctor.

GoodRx [3] warns that Advil should not be taken with other NSAIDs, such as aspirin or naproxen, as it can increase the risk of side effects. It is also not recommended for people with a history of stomach ulcers, liver or kidney disease, or heart disease.

In conclusion, the recommended dosage of Advil or ibuprofen depends on several factors, and it is crucial to follow the instructions provided by your doctor or pharmacist. Taking too much Advil can cause adverse effects, and it is advisable not to exceed the maximum daily dose of 1200 mg for adults. If you have any concerns or questions about taking Advil, it is recommended to consult a healthcare professional.
