According to the information provided, Advil (ibuprofen) should be taken with a minimum of 4 to 6 hours between doses for adults and children 12 years and older. It's important not to exceed the maximum daily dosage recommended on the label or as directed by a healthcare professional. Taking Advil more frequently than recommended can increase the risk of side effects, such as stomach pain, ulcers, and liver damage. For specific dosing instructions, it's always best to consult a healthcare professional or pharmacist.
