Qasar for my boy's tooth

At times when kids are in pain wife is nervous and so anxiety that she never knows what's happening. I remember on time when in the middle of the night our son woke up complaining his broken tooth is in pain. We woke up and check the medicines in the fridge.

My brother who is a nurse usually gives us some free medicines from his work. One of those is this QASAR Mefenamic Acid. My son's tooth, the one in pain, actually has a platinum cap because it got rotten at his early age. But that cap was accidentally remove and so exposes his tooth. After several weeks of being expose, it was then we heard him complaining about the pain. We gave him a teaspoon of this Qasar because that's the only pain reliever we have at home that time. The pain does not lose immediately but gradually it gives our son comfort until it does totally.

Right now we have this Qasar at home. If in case our son complains again about pain we have a trusted pain reliever to give him right away.
