    Question white round pill with 503

    my b/f has a whole bunch of these and i have no clue what they are. on one side they have 503 the other is a x or cross. i did the identifier and it came up with Cytoxan and Phenobarbital but those are not the pill.

    Please help.. Thanks...

    503 is 4mg Tizanidine (generic Zanaflex), a muscle relaxant.

    it's a version of lorrtab i believe. it's a strong pain killer, taken by many recreationally. it's street names are 503 & footballs to name a couple.

    No, it is Tizanidine, you could be thinking of Watson 503 which is hydro/apap 10/650mg
