For an over the counter product this works best in my opinion. The ant-inflammatory ingredient (ibuprofen) helps to relieve pain and ease muscle stress. I've tried Tylenol, Aleve and everything else and nothing comes even close. It's also a great fever reducer as well. When anyone in our family is suffering from a fever this helps to bring the temperature down quickly and helps to lessen body aches significantly. I don't like to guess when my kids have a fever and feel awful. You know how that is with a fever, the muscle aches and misery it can cause. Who wants to worry more because they aren't sure if a product is going to work? Not me. I always reach for Advil. I'm actually surprised at how well it handles pain and really helps me with the intense headaches I sometimes get. I'd absolutely recommend it! Heck, I use it quite a bit so of course!
