I have a photo of a bag of pills. The pill is white and it is a cube shape. It is powdery inside of the bag and if I can see correctly (since the photo isn't very clear) There is a either a 3 or 8 on one side of the pill then a line and another number after the 3/8. There's also something behind it but I cannot make out what the number is.
I wish I could give you a bit more information but I do have a picture of it that I would post if i was able too.

I really need to know what pill this is, it's extremely important. Thank you all for your help ahead of time!
