One of the major differences between these two drugs is that one is a generic drug, and the other is a branded drug. Of course, ibuprofen is an example of a generic drug, while Motrin is just a brand name of ibuprofen. Most times, Motrin is considered to be more effective compared to ibuprofen.
This might not be unconnected to the fact that branded drugs offer more benefits compared to generic drugs. Although both are painkillers, ibuprofen is used mostly to treat inflammation in arthritis and dysmenorrheal, while Motrin can be used to treat backache, toothache, arthritic pain, headache, menstrual cramps, muscular aches, etc.
Unlike ibuprofen that exists only in tablet form, Motrin exists in three forms i.e., syrup, tablet, and capsule. Another difference is that Motrin is a little bit expensive compared to ibuprofen. Although the two drugs can be bought over the counter, but they should not be misused because they can worsen the condition of people with certain health issues.
