I have been taking metforman er ( 2 in evening ). Occasionally I have diarrea & about 4 months ago I checked my stool . I have discovered many pill size pieces of glycerine covered meally centered objects . What I would like to know is what they are . Is the er metforman combined with the diarea NOT having time to disolve the pill ?
Metformin ER is an extended release tablet. This is made by using a polymer matrix with the drug incorporated into it. GI fluids hydrate and swell the matrix then the drug is slowly released from the matrix (based on pH dif). The matrix may occasionally remain intact and excreted in the faeces - which is what you have seen. Harmless and no need to be concerned about the drug not being absorbed. Hope this helps.
