Motrin IB is a non-steroidal anti-inflammatory drug that's designed to relieve aches and pains due to the common cold, menstrual cramps, toothaches and backaches, and temporarily reduce fever. It's my main drug to use for cramps, headaches, and the occasional toothache and the common cold.
Usually, only 1 pill is needed to work for whatever I want to relieve, but whenever I have menstrual cramps or when I had a more severe toothache I'll take another pill a few minutes afterwards. My grandmother had a bad case of gout recently and Motrin IB helped her to get relief for a few hours so she could get some sleep. Relief starts to kick in in about 5-10 minutes after swallowing the pill(s).
Motrin (and Aleve and probably others) have a warning about stomach bleeding that I've never noticed before. One of the higher risk factors for getting stomach bleeding with Motrin IB is the use of a blood thinning or steroid drug. Now, I'm no doctor, so you can take what I'm about to type next with a grain of salt. But my grandmother (in addition to a bunch of other medical problems) takes medicine to thin out her blood, and we were concerned about her taking Motrin. However, it didn't seem to effect her negatively. She only took it a couple of times, though, before she switched to Tylenol with Codeine, which the doctor said was okay for her to take.
Basically, Motrin IB works. I've used it right at the beginning of menstrual cramps before they can get even worse, stopping them in their tracks. I use it when I feel a headache coming on and it goes away. I've used it to help subside coughing and sneezing and phlegm buildup during the common cold. I'd highly recommend it to anyone who wants pain or common cold relief.
