Nurse Practitioner Prescriptive Authority
Nurse practitioners, being highly educated and experienced in the field of nursing, are given prescriptive authority to varying degrees across the United States. If you want to become a nurse practitioner, you will likely need to complete a Master of Science in Nursing (MSN) program. The extent of a nurse practitioner’s prescriptive authority largely varies by the schedule of the drug in question, with some states allowing a larger degree of prescriptive authority to nurse practitioners and some regulating this prescriptive authority more closely.
The following is a state-by-state breakdown of nurse practitioner prescriptive authority, according to the American Medical Association (AMA)’s Nurse practitioner prescriptive authority – State law chart as of 2021. Check with your state’s board of nursing for more up-to-date information.
Schedule II, III, IV, and V drugs can be found described by the Drug Enforcement Administration (DEA) – Diversion Control Division Controlled Substances Schedules.

Schedule III-V Controlled Substances Prescriptive Authority
Schedule III substances
are described as having a potential for abuse less than schedule I or II and such abuse could lead to a level of moderate to low physical dependence or a high psychological dependence. These include substances with less than 90mg of codeine per dosage, for example.
Schedule IV substances
have a low potential for abuse when compared to substances in schedule II. These may include Xanax, Klonopin, and Valium.
Schedule V substances
have a low potential for abuse when compared to schedule IV substances and consist mostly of limited quantities of certain narcotics, such as cough medicines with no more than 200mg of codeine per 100ml.
Generally speaking, the lower the schedule number, the more potential a drug has to be dangerous or misused and therefore requires a higher level of regulation.
