HI, i was going though my medicine cabinet and found a pill in a bottle marked keflex, im pretty good with pills and i KNOW this is not keflex. Its a small white, maybe cream colored pill with a large M on one side(no box around it) and on the other side its scored down the middle... Now the top of the score is chipped off and that very well be the reason i cant find its identity, but the bottom of it clearly reads 2. It is positioned just like this under the score(score runs left to right and 2 is straight underneath it). Any help you could give me would be excellent or point me in the direction of photos or anything, Thanks
