Ibuprofen or Aleve?

[earache]

I've got lower back problems and have been taking Ibuprofen for years to reduce swelling and pain. I go through a lot of the stuff and I worry about what it's doing to my liver. Dr has me do blood tests several times a year to check liver function. Unfortunately Ibuprofen is not as effective as it once was for me, so I'm looking for alternatives. What do you think about Aleve? My doc doesn't seem to hold it in high regard, but I'm really not happy about sticking with Ibuprofen and increasing dosage.
