Exceeding the recommended dosage of any medication, including Advil (ibuprofen), can lead to a range of adverse health effects. According to the National Institutes of Health (NIH) [1], the recommended maximum daily dosage of ibuprofen for adults is 3200 milligrams (mg) per day. Exceeding this limit can increase the risk of side effects such as stomach pain, ulcers, internal bleeding, headaches, dizziness, and in rare cases, kidney failure or liver damage.

The NIH also notes that long-term use of ibuprofen at high doses can increase the risk of heart attack and stroke [1]. Moreover, the U.S. Food and Drug Administration (FDA) advises that individuals should not exceed the recommended dosage for over-the-counter (OTC) medications, as doing so can increase the risk of serious side effects [2].

It is important to note that the maximum daily dosage of ibuprofen can vary depending on factors such as age, weight, and overall health. Therefore, it is always recommended to consult with a healthcare provider before taking any medication, especially if you have any pre-existing medical conditions or are taking other medications.

In summary, exceeding the recommended dosage of Advil can lead to a range of adverse health effects, including stomach pain, internal bleeding, headaches, dizziness, and in rare cases, kidney failure or liver damage. Long-term use of ibuprofen at high doses can also increase the risk of heart attack and stroke. It is essential to consult with a healthcare provider before taking any medication and to follow the recommended dosage instructions carefully.
