Back in the days when NSAIDs were prescription only, the gyno prescribed them for cramps. They were to be taken daily beginning at least 5 days before the period was due and on the first day until the cramps stopped. Taken that way, I didn't have cramps at all. I took the pills from 7-10 days per month.

NSAIDs inhibit the body chemical that causes the uterus to contract. The contractions are what cause the cramps.

NSAIDs are now OTC, with Alleve, Advil and Motrin being the most popular brand names. Generics are just as good -- naprosyn and ibuprophen.

If you have a sensitivity or if you take too much NSAIDs at once or take it for too many days in a row it can cause gastro-intestinal upset, sometimes severe.

Taking it the week before my period was due to start changed my life. No more severe PMS and no more writhing in agony cramps. I had very mild PMS, but nothing very bad. Taking it on the first day of the period doesn't have the same effect. It has to be taken in advance to prevent the cramps from even getting started.

Good luck.
