The drawback of Ibuprofen is that it tends to cause damage to stomach and intestinal linings. That's why you are advised to take with food and/or lots of water. You don't want it absorbing all in one place. Long term use exacerbates the effect, making it more likely to cause ulcers and eventually internal bleeding. My partner ended up in the hospital with a serious internal bleed caused by taking Ibuprofen daily for chronic pain. I'm not saying don't use it, just be aware of the risks.
