Do ibuprofen and alcohol together cause liver or kidney damage?

Yes it can cause liver bleeds. Also mega doses can cause damage alone.

Each of these drugs have their own side effects including liver damage (alcohol), stomach damage (both), kidney damage (ibuprofen). Taking both ibuprofen and alcohol can result in gastritis, or inflammation of the stomach lining, which would lead to stomach pain, low grade blood loss and possibly an ulcer. It is also possible that becoming dehydrated due to alcohol could increase your chance of having kidney damage from ibuprofen, but this is just speculation. The most likely effect would be gastritis. “Liver bleeds” are not a real medical issue, and would not be caused by either medicine alone or in combination.

I think the key here is….....moderation
One margarita after taking a couple of headache tablets isn’t going to land you in hospital if you’re otherwise healthy. But, as shilolo mentioned, but substances can have less desirable effects.

it can also give you ulcers

Does flutter have to worry about legal implications of medical stuff on this site. I would hope that they would be immune from suit because they are simply a vehicle for the free exchange of information, and they make no claims as to the accuracy of that info. I do have to wonder though if, in this law-suit-happy country we live in, someone could try to get some money because they followed some bad advice—especially with regards to medical information.

I hope not, as the ibuprofen before bed after a night of drinking means less of a hangover the next morning for me!
