Yes, lacosamide is a controlled substance. The Drug Enforcement Administration classifies it as a federal Schedule V drug, the lowest of the five tiers under the Controlled Substances Act, and that designation applies to both brand-name Vimpat and every FDA-approved generic version.1eCFR. 21 CFR Part 1308 – Schedules of Controlled Substances – Section: 1308.15 Schedule V Schedule V is the least restrictive category, but it still triggers real federal rules around how the drug is prescribed, refilled, carried, shared, and thrown away.
What Schedule V Means
The federal drug schedules run from I to V, ranked by abuse potential and accepted medical use. Schedule V sits at the bottom: substances with a low potential for abuse relative to Schedule IV, an accepted medical use in the United States, and only limited risk of physical or psychological dependence.2Drug Enforcement Administration. Drug Scheduling Other familiar Schedule V drugs include certain low-dose codeine cough syrups and the anti-diarrheal diphenoxylate.
The DEA placed lacosamide in Schedule V in March 2009 after preclinical animal studies and human clinical trials showed subjective effects comparable to Schedule IV drugs, though its overall abuse profile was lower.3Federal Register. Schedules of Controlled Substances: Placement of Lacosamide Into Schedule V The drug is approved to treat partial-onset seizures and, since November 2020, to serve as adjunctive therapy for primary generalized tonic-clonic seizures in patients four and older.4DailyMed.

How the Classification Affects Your Prescription
Because lacosamide is controlled, every prescription must include the date written, your full name and address, the drug name and dosage, and the prescriber’s name, address, and DEA registration number.5eCFR. 21 CFR 1306.05 – Manner of Issuance of Prescriptions A prescription missing the DEA number is not valid, even if it would pass for an ordinary drug. Schedule V prescriptions can be sent to the pharmacy in writing, orally, electronically, or by fax.
Refills are where Schedule V is friendlier than the higher tiers. Schedule II drugs cannot be refilled at all. Schedule III and IV prescriptions cap out at five refills within six months.6eCFR. 21 CFR Part 1306 – Controlled Substances Listed in Schedules III, IV, and V Federal law doesn’t impose that five-refill ceiling on Schedule V specifically, but it does prohibit any dispensing, including partial fills, more than six months after the prescription was written.7eCFR. 21 CFR Part 1306 – Prescriptions After that six-month mark, you need a new prescription no matter how many refills are still printed on the label. Individual states can and do set stricter limits.
What You Can and Cannot Do With the Medication
A valid prescription authorizes only the named patient to possess and use the drug. Handing even a single pill to a spouse, parent, or friend meets the federal definition of illegal distribution, no matter the reason.8Office of the Law Revision Counsel. 21 USC 844 – Penalties for Simple Possession
Keep the medication in a secure place, ideally a locked cabinet or medicine safe, to protect it from theft and from children. If pills are stolen, file a police report right away. Most states don’t legally require patients to report a theft, but you’ll almost certainly need the report to get a replacement supply. Bring it to your prescribing doctor first; they carry more weight with the pharmacy than you will on your own.
Traveling With Lacosamide
Inside the United States
The TSA doesn’t require medications to be in the original prescription bottle for domestic flights, and you don’t have to declare pills at screening. Quantities in pill form aren’t capped, though they go through X-ray. Liquid lacosamide is exempt from the standard 3.4-ounce carry-on limit, but you must tell the officer about it before screening starts.9Transportation Security Administration. Travel Tips Some states have their own prescription-labeling rules, so keeping the pharmacy label on the bottle is the safest habit.
Across International Borders
Rules tighten sharply once you leave the country. Most destinations require a written prescription from a licensed doctor, sometimes translated into the local language, and many cap the amount you can bring to a 30- to 90-day supply. Travel within the Schengen Area, which covers most of the European Union, requires a specific Schengen medical certificate issued by your home country’s health authority and valid for up to 30 days.10INCB. General Information for Travellers Contact the embassy or consulate of your destination before you fly, since requirements vary and some countries control substances that others do not.
Disposing of Unused Pills
Lacosamide is not on the FDA’s flush list, so don’t put unused pills down the toilet.11U.S. Food and Drug Administration. Drug Disposal: FDAs Flush List for Certain Medicines The preferred route is a DEA-authorized take-back program. Many pharmacies and law enforcement agencies run collection sites year-round, and the DEA holds periodic National Prescription Drug Take Back events.
If no take-back site is nearby, the DEA says to remove the pills from the container, mix them with something unappealing like used coffee grounds or cat litter, seal the mixture in a bag, and put it in the household trash. Scratch out personal information on the empty bottle before you throw it away.12DEA. How to Properly Dispose of Your Unused Medicines
Penalties for Breaking the Rules
Possessing lacosamide without a valid prescription is a federal offense. A first conviction carries up to one year in prison and a minimum $1,000 fine. A second offense runs from 15 days to two years with a minimum $2,500 fine. A third or later offense means 90 days to three years and at least $5,000, plus the reasonable costs of investigation and prosecution.8Office of the Law Revision Counsel. 21 USC 844 – Penalties for Simple Possession
Distribution charges are heavier. A first offense of selling, sharing, or dispensing lacosamide outside legitimate medical channels can bring up to one year in prison and a fine of up to $100,000 for an individual or $250,000 for a business. With a prior felony drug conviction, the maximum climbs to four years in prison, a $200,000 fine ($500,000 for a business), and up to a year of supervised release afterward.13Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A These are federal figures. States prosecute their own controlled substance offenses, so a single incident can produce charges on both tracks.
