If someone takes 2 Alleve every day, how long would it take to get kidney damage?
I don't think you wanna test that out honestly. My friend (who is a doctor) told me that a lot of medicines are hard on the kidneys especially when it's used frequently.Either way you will not have any way of knowing when kidney damage would start.
I doubt that taking only 2 daily will give you kidney damage.
It would be your liver, not your kidneys... 2 aleve a day isn't going to hurt you liver or your kidneys for that matter... It's when you take medication or alcohol in excess... No worries
Call your doctor or pharmacist, they can give you the answer pertaining to your situation.
