What is the difference in labeling of Ibuprofen?

At Wall mart you have Ibuprofen labeled one for migraine, another version labeled for inflammation, and another version of ibuprofen labeled for pain....all of these products have the same mg of active ingredients, I tell my wifes aunt who reads the labels and believes every word, that these labels are designed by advertising people and she needs to take these labels with a grain of salt..........true or false?
