A patient is taking methadone as part of a heroin withdrawal program. The nurse understands that in this instance methadone is classified as which drug schedule?

A. C-V drugs are considered to have the lowest potential for abuse and are typically used for medications like cough preparations with less than 200 milligrams of codeine per 100 milliliters or per 100 grams. Methadone is not classified under C-V. B. Methadone is classified as a C-II (Schedule II) controlled substance because it has a high potential for abuse, but it also has accepted medical uses, such as for opioid withdrawal management. C. C-I drugs are considered to have no accepted medical use and a high potential for abuse (e.g., heroin, LSD). Methadone is not classified as a C-I drug. D. C-III drugs have a moderate potential for abuse and are generally used for medications like anabolic steroids or some barbiturates, but methadone is not classified under C-III.
