Levetiracetam is not a controlled substance. It does not appear on the DEA’s list of scheduled drugs, and it carries no restrictions related to abuse potential in the United States. You can fill a prescription for levetiracetam at any pharmacy without the special requirements that apply to controlled medications, such as limits on refills or mandatory ID checks.
Why It’s Not Controlled
The DEA places drugs into one of five schedules (I through V) based on their potential for abuse, physical dependence, and accepted medical use. Levetiracetam doesn’t meet the criteria for any of these schedules. It works through a unique mechanism in the brain that doesn’t produce the euphoria, sedation, or reward response associated with drugs that carry abuse potential.
This makes levetiracetam different from several other seizure medications that are controlled. Phenobarbital, a barbiturate used for epilepsy since the early 1900s, is a Schedule IV substance. Benzodiazepines commonly used for seizures, including diazepam, lorazepam, and clonazepam, are also Schedule IV. Pregabalin, another anti-seizure drug, sits in the same category. All of these drugs affect the brain’s GABA system in ways that can produce dependence and a sense of calm or euphoria, which is why they carry scheduling restrictions.
Levetiracetam doesn’t work on GABA receptors. Its mechanism is distinct enough that it simply doesn’t carry that risk profile.
What This Means for Your Prescription
Because levetiracetam isn’t scheduled, your doctor can prescribe it with standard refills. You won’t need a new written prescription each month the way you would with a Schedule II drug, and pharmacies can transfer prescriptions between locations without the added paperwork that controlled substances require. In most states, it can also be called in or sent electronically without the security requirements that apply to scheduled medications.
Outside the U.S., levetiracetam holds a similar status. In Australia, it’s listed on the Pharmaceutical Benefits Scheme under the General Schedule, meaning it’s a subsidized prescription medication without controlled-substance restrictions. The UK and Canada treat it the same way: a prescription-only medication, but not a controlled drug.
How Levetiracetam Is Used
Levetiracetam is one of the most widely prescribed seizure medications in the world. While it technically lacks FDA approval for use as a sole treatment in the U.S., doctors routinely prescribe it that way, and it is approved for initial monotherapy in Europe. It’s used for both focal seizures (which start in one area of the brain) and generalized tonic-clonic seizures (the type most people picture when they think of epilepsy).
It holds a unique distinction among seizure drugs: it’s the only one with the highest level of clinical evidence supporting its effectiveness against myoclonic seizures, which cause brief, involuntary muscle jerks. For girls and young women with juvenile myoclonic epilepsy, it may work better than some alternatives, particularly when valproate isn’t recommended. An intravenous form is also available for use in hospital settings when seizures don’t stop on their own.
Side Effects to Know About
The fact that levetiracetam isn’t a controlled substance doesn’t mean it’s free of significant side effects. The most common ones are drowsiness, dizziness, and fatigue. These tend to be most noticeable when starting the medication or increasing the dose, and research suggests that the drug often reaches its full effectiveness at the initial dose. Pushing the dose higher doesn’t always add benefit but can increase side effects.
The side effect that gets the most attention is mood and behavior changes, sometimes called “Keppra rage” after the brand name. Psychiatric reactions occur in up to 16% of patients and are a frequent reason people stop taking the drug. A study published in JAMA Neurology found that among patients who experienced psychiatric side effects, depression was the most common (affecting about 22% of that group), followed by anxiety (nearly 14%) and, rarely, psychosis (about 3%). Irritability and hostility are more common in children than adults. Aggression, personality changes, and suicidal thoughts have also been reported, though less frequently.
These behavioral effects are worth understanding because they can be mistaken for a separate psychiatric condition rather than a medication side effect. If you or someone you know starts levetiracetam and notices unusual irritability, sadness, or personality shifts within the first weeks, that pattern is well recognized and worth discussing with a prescriber.
