This particular brand of ibuprofen works really good for headaches and even migraines, especially if you catch in the beginning before it peaks. For me, I am really glad that it does not upset my stomach at all and it does not leave me jittery. Effectiveness It is a very effective medication, although I have to say that I started out taking 2 for headache pain and I now have to take at least 4 or 5 in order to get any relief. Despite this, this medication is still a great alternative to the major brands on the market nowadays. Some of which you get absolutely no relief from them. Ease of Use Pretty easy to take. I think 1 pill is 500 mg so 2 normally does the trick, unless you have built up tolerance, then 2 will do nothing for you. Immediacy These pills work pretty good and pretty fast. I would have to say that the relief you get is a gradual reduction in headache pain to a point when you don't even realize when the headache stopped hurting.
