Yes, Ibuprofen will help with menstrual cramps since the cramps are in part due to prostaglandins. And ibuprofen is a prostaglandin inhibitor. But for anyone reading this that is still suffering from menstrual cramps there are safer alternatives, in particular the smooth muscle relaxants such as magnesium malate, kudzu root, cramp bark or silk tassel.
I wish I had that info years ago! Back then, there was no internet. I used to spend time leafing through books looking for any natural options. For example, back then a nurse told me to really up my calcium intake---even recommended a supplement. I tried that---didn't work. But I digress... As I said before, now I just don't use any NSAIDs---and certainly don't miss them either!
Calcium is a muscle contractor, so it can make menstrual cramps worse. Magnesium is the muscle relaxant.
The drug companies and the FDA have been hiding known side effects of drugs for years. Again with NSAIDs like ibuprofen they have known these drugs increase the risk of heart attack and stroke for decades. It was not until just a few years ago that these side effects of NSAIDs started coming to the public light. Same with Premarin, which we have know for an extremely long time increases the risk of cancer. But the FDA did not admit to this well known fact until about 6 years ago. This is why there is a major problem with how cozy the FDA is with the pharmaceutical companies.
Thanks for putting the utterly inhumane nature of prescription and non-prescription drugs into perspective.
Ibuprofen is established to be ototoxic (nerve-cell damage causing) as you alluded to - a more common established cause of tinnitus than many doctors will openly admit. Hundreds of thousands, if not millions of people are likely giving themselves tinnitus at this moment by taking a seemingly innocuous non-prescription medication such as Ibuprofen, Advile or Alleve.
I go into details about how the drug and food manufacturers combine to cause the health imbalances that cause tinnitus here: Naturally Curing Tinnitus
