This is an oblong pill, white, with what looks like a triangle with an unidentifiable imprint in the center of the triangle, then a score mark for breaking in half followed by the letter "M" (I think). There are no marks on the other side of the pill other than another score mark. I have two meds that are suspect that I use. Rizatriptan (Maxalt brand name) for migraines or Metroprolol for high blood pressure. I get my Rizatriptan from Canada, because I cannot afford it here.
