Gabapentin is not a controlled substance under federal law, but a small number of states have independently classified it as a Schedule V controlled substance. As of late 2024, seven states plus Washington, D.C. (eight jurisdictions total) have taken this step, making gabapentin subject to tighter prescribing and dispensing rules in those areas. Several additional states require gabapentin prescriptions to be reported to their prescription drug monitoring programs without formally scheduling the drug.
States That Classify Gabapentin as Schedule V
The states that have classified gabapentin as a Schedule V controlled substance include Alabama, Kentucky, Michigan, North Dakota, Tennessee, Virginia, and West Virginia, along with Washington, D.C. Schedule V is the least restrictive controlled substance category, the same tier that includes certain cough syrups containing small amounts of codeine. All eight jurisdictions also require pharmacies to log gabapentin prescriptions in their prescription drug monitoring programs.
Kentucky was one of the earliest movers, scheduling gabapentin in 2017. Virginia followed in 2019. Other states have adopted their laws at various points between 2017 and 2024. The trend has been gradual rather than a sudden wave, and different states passed their laws in response to local patterns of misuse.
States That Monitor Without Scheduling
A larger group of states takes a middle path: they require gabapentin prescriptions to be reported to the state’s prescription drug monitoring program but stop short of classifying the drug as a controlled substance. This means prescribers and pharmacists must log each gabapentin prescription in the state database, but the drug itself doesn’t carry the legal restrictions that come with scheduling. The practical difference for patients in these states is minimal at the pharmacy counter, though their prescribers can see gabapentin fills alongside opioid and benzodiazepine records when checking the monitoring database.
Why Some States Took This Step
The push to control gabapentin stems from its interaction with opioids. Gabapentin works by reducing calcium signaling in nerve cells, which is how it manages nerve pain and seizures. But that same mechanism also amplifies the effects of opioids. Research published in the Proceedings of the National Academy of Sciences confirmed that gabapentin enhances opioid activity at the cellular level, with potentially fatal consequences. People misusing opioids sometimes take gabapentin alongside them to intensify the high, and coroners in several states began flagging gabapentin in overdose deaths.
Gabapentin also carries its own mild euphoric effects at high doses, which contributed to a pattern of nonmedical use in communities already affected by the opioid crisis. States with the highest rates of opioid overdose deaths, particularly in Appalachia and the Southeast, were generally the first to act.
What Schedule V Means for Your Prescription
If you live in a state where gabapentin is Schedule V, you’ll notice several practical differences. Your prescription expires six months after the date it was written and can be refilled a maximum of five times. After that, you need a new prescription from your provider. Your pharmacist will log the prescription in the state monitoring database, and you may need to show a valid ID when picking it up.
Transferring prescriptions between pharmacies can also be more cumbersome for controlled substances, and some states limit or prohibit transfers entirely. If you’re traveling from a state where gabapentin is controlled to one where it isn’t (or vice versa), the rules of the state where you fill the prescription apply.
Unintended Effects on Patient Access
Scheduling gabapentin has created measurable access problems for people who take it for legitimate medical reasons. After Virginia reclassified gabapentin, the proportion of epilepsy patients who maintained adequate medication coverage dropped from 67.5% to 60.2%. That 7.5 percentage point decline represents real patients going without a drug they need to prevent seizures.
In Kentucky, the effects were even more striking in populations already struggling with substance use. Before scheduling, 55% of people who used gabapentin nonmedically obtained it from regulated sources like pharmacies. After scheduling, that figure dropped to roughly one-third. But nonmedical use didn’t decline. Instead, people shifted to unregulated sources, meaning the policy reduced access for legitimate patients while pushing nonmedical use further outside the healthcare system where it’s harder to monitor or intervene.
Federal Status Remains Unchanged
The DEA’s Diversion Control Division states plainly that gabapentin is not controlled under the federal Controlled Substances Act. There is no active federal proposal to change this. The state-level scheduling decisions are independent actions taken under each state’s own pharmacy and drug laws, which is why the legal status of the same medication varies depending on where you live. If you move between states or fill prescriptions across state lines, it’s worth checking the rules in the state where your pharmacy is located.
