banned for the FDA is crap nowadays.
Ibuprofen does not have an intentional design as an antibiotic, but it does produce a hazardous environment for some bacteria, both because it interacts with certain bacteria like it does with your liver and because it keeps the inflammation down, which allows your immune system to act more efficiently. Generally I would agree not to exceed the amount, but if your liver is good, you should be tolerant. No one said to mix it with alcohol.
Keep in mind I'm talking 8 in the first day (thinking 200 mg tablets and only going 2 over the max recommended), and then 6 a day for the next 2 days. Not a severe impact if you take care of yourself.
