For ibuprofen, you have to exceed the dosage by a large amount; you have to be really trying. This is evidenced by the dosage information on the packages themselves, which are totally inconsistent: 2x200mg 4 times a day is the max… But so is 2x400mg 4 times a day. But 2x600mg 4 times a day is the prescription dose. The more relevant danger of ibuprofen is chronic use, which can cause severe stomach issues.
At least this is what I’ve been able to find. But I still follow the dosage on the bottle because I’m not gonna risk it for a headache.
Yeah, from what I can tell if you frequently use ibuprofen it can be a problem. I thought it was mostly stomach but I’m not a medical expert so some of the sources were difficult for me to understand. Maybe it’s kidneys too. Or maybe I’m completely mistaken.
