What is Keppra (levetiracetam)? This complete 2026 guide covers FDA-approved uses, dosage forms, how to take it, and key things every patient should know.

Keppra is one of the most prescribed anti-seizure medications in the United States, with over 6 million prescriptions filled in 2023. But many patients and caregivers who receive a Keppra prescription have questions: What exactly is it? What does it treat? How do you take it? This guide covers everything you need to know in plain English.

What Is Keppra?

Keppra is the brand name for levetiracetam, an anti-seizure (antiepileptic) medication used to treat epilepsy. It belongs to the pyrrolidine anticonvulsant class and is chemically unrelated to all other anti-seizure medications — it works through a unique mechanism compared to older epilepsy drugs.

Levetiracetam was first approved by the FDA in 1999. A generic version became available in the United States in 2008. Today, it's available under several brand names including Keppra, Keppra XR (extended-release), Spritam (rapidly dissolving tablet), and Roweepra. It is not a controlled substance.

What Does Keppra Treat? FDA-Approved Uses

Keppra (levetiracetam) is FDA-approved to treat three types of seizures:

Partial-onset (focal) seizures in patients 1 month of age and older — these are seizures that originate in one area of the brain

Myoclonic seizures in patients 12 years and older with juvenile myoclonic epilepsy (JME) — brief, shock-like muscle jerks

Primary generalized tonic-clonic seizures in patients 6 years and older — the "grand mal" seizures most people are familiar with

Keppra can be used as a standalone treatment (monotherapy) or added to other anti-seizure medications (adjunctive therapy). It is sometimes used off-label for status epilepticus and post-traumatic seizure prevention.

What Forms Does Keppra Come In?

Keppra is available in multiple formulations to suit different patients:

Immediate-release tablets: 250 mg (blue), 500 mg (yellow), 750 mg (orange), 1000 mg (white) — taken twice daily

Extended-release tablets (Keppra XR): 500 mg, 750 mg — taken once daily

Oral solution: 100 mg/mL grape-flavored liquid — useful for children and patients who can't swallow tablets

IV injection: Used in hospital settings for patients 15 years and older who cannot take oral medication

Spritam: A 3D-printed rapidly dissolving tablet formulation for patients who have difficulty swallowing

What Is the Typical Keppra Dosage?

Dosage varies by age, weight, seizure type, and kidney function. Always follow your doctor's specific instructions.

Adults and teenagers 16+ (immediate-release): Starting dose is 500 mg twice daily (1000 mg/day total). This can be increased in 1000 mg/day increments every 2 weeks. Maximum dose is 3000 mg/day.

Children 4–15 years: 10 mg/kg twice daily, with a maximum of 60 mg/kg/day

Children 6 months to 3 years: 10 mg/kg twice daily (oral solution), maximum 50 mg/kg/day

Patients with kidney impairment may need lower doses. Levetiracetam levels also decrease during pregnancy, so monitoring and dose adjustments are common in pregnant patients.

How Should You Take Keppra?

Can be taken with or without food

Swallow tablets whole — do not crush or chew extended-release tablets

Try to take doses at the same time each day for consistent blood levels

If you miss a dose, take it as soon as you remember — if it's almost time for your next dose, skip the missed one

Never stop taking Keppra abruptly — this can cause withdrawal seizures

Key Facts About Keppra

Not a controlled substance — no DEA restrictions on prescribing

Approved for use in infants as young as 1 month for partial-onset seizures

Considered one of the safer options in pregnancy among anti-seizure medications

Fewer drug interactions than many older anti-seizure drugs (not metabolized by the liver's CYP450 system to any significant degree)

Available as a highly affordable generic starting at ~$6 with discount coupons

Frequently Asked Questions

Keppra (levetiracetam) is an FDA-approved anti-seizure medication used to treat three seizure types: partial-onset (focal) seizures in patients 1 month and older, myoclonic seizures in juvenile myoclonic epilepsy (patients 12+), and primary generalized tonic-clonic seizures (patients 6+). It can be used alone or with other seizure medications.

Keppra (immediate-release) is taken twice daily, while Keppra XR (extended-release) is taken once daily. The total daily dose is the same for both formulations. Keppra XR contains the same active ingredient (levetiracetam) but releases it more slowly over 24 hours. Both are FDA-approved for partial-onset seizures.

Yes. Keppra is the brand name for levetiracetam, the generic drug. They contain the same active ingredient and are considered bioequivalent by the FDA. Generic levetiracetam has been available since 2008 and is dramatically less expensive than brand Keppra. Other brand names include Roweepra and Spritam.

Levetiracetam is absorbed quickly — it reaches peak blood levels within 1 hour of taking a dose. However, achieving stable therapeutic levels and seeing a reduction in seizure frequency typically takes a few days to weeks, especially as the dose is gradually increased. Some patients notice improvement quickly; others may need dose adjustments over several weeks.

Keppra is only FDA-approved for seizure disorders. Research has not found it to be useful for anxiety, neuropathic pain, or essential tremors. It is sometimes used off-label for status epilepticus (emergency seizures) and post-traumatic seizure prevention. Always consult your doctor before using any medication off-label.
