For Period Pain "I have been taking Mefenamic Acid 500 mg tablets for over 2 years now. I suffer with heavy, painful periods and have done so for many years. I take this medication when my period begins and throughout the days of my period. I also take paracetamol alongside it. It has made a massive difference in my life! It has reduced bleeding and helped with pain, but I do need paracetamol in addition, as it won't help with the pain if I take it alone. Just recently, it hasn't been as effective, meaning my bleeding appears to have increased, so I'm now looking at alternatives. However, all in all, it has been extremely helpful for me over the past couple of years. The side effects can be horrendous! If you don't eat just before taking this. I have used this on an empty stomach and really suffered with severe back pain, really crippling pain. This doesn't happen if I follow the correct guidelines and take it on a full stomach."

For Period Pain "My pain usually starts 3-4 days before my period actually comes. Tylenol #3 is the only thing that still helps me function normally during this time of the month. The doctor gave me mefenamic acid to try this time. After taking this, my pain is not only in my lower back but also pain and intense cramping in my uterus... this stuff doesn't help my issues at all, if anything, it made it worse!"

For Period Pain "I have never taken tablets that give me such bad side effects. When I take these, I have to stay absolutely still for a good hour, otherwise, if I do move and they’re kicking in, I get severe lower back and stomach pain. To the point where I’m shaking and have to get on my hands and knees. And the slowing of the blood loss was very, very delayed and slow. Still bleeding a week after I started taking them."

For Period Pain "When I first got my period, I used to be able to use paracetamol and ibuprofen to take away the pain, but as the years went by, it no longer worked, and I was being sick, shaking, and in excruciating pain. So mefenamic acid was recommended, and it has done nothing to help with the pain. The only good thing is that it shortens my period from 7 days down to 3 or 4 days. It has also made my back pain when I’m on my period worse, it’s gotten so bad that my back starts to seize up, and I’m left curled up and crying."
