IT IS NOT METHADONE FOR SURE!!!! They come in a round white shape, little ones are 10 mg, and there are huge silver-dollar sized ones (Diskets) that are 40 mg. Then it comes in clear I.V. liquid or oral solution (Red cherry-flavored.) Sounds to me like it could be a Lortab 10mg. They are oblong and are like a blueish-green color kinda like this smiley Hope this helps. Don't take it, especially if it wasn't prescribed for you. METHADONE IS VERY DANGEROUS TO THOSE WHO ARE OPIOID NAIEVE.
