Keppra (levetiracetam) is an anticonvulsant used to prevent and control seizures. In the United States, it is FDA-approved as an adjunctive therapy for partial-onset seizures in adults and children, myoclonic seizures in patients with juvenile myoclonic epilepsy, and primary generalized tonic-clonic seizures. It is also commonly used as monotherapy for partial-onset seizures in certain age groups, based on clinical guidance.
Clinicians value Keppra because it acts through a unique synaptic vesicle protein 2A (SV2A) binding mechanism, which helps stabilize neuronal activity. Unlike many antiepileptic drugs, it has minimal hepatic metabolism and few clinically significant drug–drug interactions. Patients often notice benefits such as simplified titration, relatively predictable blood levels, and flexible formulations (tablets, extended-release tablets, oral solution, IV in hospitals).
Keppra is not a cure for epilepsy; rather, it helps reduce seizure frequency and severity. Best outcomes come from individualized treatment plans that consider seizure type, comorbidities (such as mood disorders or kidney disease), and patient lifestyle, along with regular follow-up and monitoring.
Keppra dosing is individualized. Typical adult starting doses for immediate-release tablets are 500 mg twice daily. Clinicians may increase by 500 mg twice daily every two weeks based on response and tolerability, with a usual total daily dose of 1000–3000 mg. Extended-release (XR) tablets are often started at 1000 mg once daily, with adjustments as needed. Pediatric dosing is weight-based and carefully titrated by the prescriber, often beginning at low mg/kg doses and increasing gradually.
Directions for use:
In hospital settings, intravenous levetiracetam may be used when oral dosing is not possible. The IV dose is typically equivalent to the total daily oral dose and is administered over a short infusion, per clinical protocols.
Behavior and mood changes: Keppra can cause irritability, agitation, aggression, mood swings, anxiety, depression, and, rarely, psychosis or suicidal thoughts/behaviors. Patients and caregivers should monitor for new or worsening mood symptoms, especially during the first few months or after dose changes, and report concerns promptly.
Sedation and coordination: Drowsiness, fatigue, dizziness, and coordination difficulties can occur. Until you know how Keppra affects you, use caution with driving, operating machinery, or activities that require full alertness.
Hypersensitivity and serious skin reactions: Although uncommon, serious allergic reactions, including anaphylaxis, Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported. Seek urgent care for rash, blistering, facial swelling, or trouble breathing.
Blood-related effects: Rare cases of neutropenia, leukopenia, anemia, and thrombocytopenia have been reported. Clinicians may order labs if symptoms such as frequent infections, unusual bruising/bleeding, or persistent fatigue occur.
Renal function: Because levetiracetam is primarily eliminated by the kidneys, dose reductions are needed in kidney impairment. Regular monitoring may be advised, particularly in older adults or those with chronic kidney disease.
Pregnancy and breastfeeding: Uncontrolled seizures pose risks during pregnancy. Available data suggest levetiracetam is among better-studied antiseizure options in pregnancy, but decisions are individualized. If planning pregnancy or pregnant, do not stop Keppra abruptly; discuss risk–benefit with your clinician. Levetiracetam is excreted into breast milk; monitoring infants for sedation or feeding issues may be recommended.
Alcohol and CNS depressants: Alcohol can worsen sedation and may lower seizure threshold in some individuals. Combining with other sedating drugs can intensify drowsiness or dizziness. Discuss your full medication and supplement list with your clinician.
Known hypersensitivity to levetiracetam or any of the formulation components is a contraindication. Caution and close monitoring are advised in patients with a history of significant psychiatric symptoms, renal impairment (dose adjustment required), or previous serious drug reactions. As with any antiepileptic, changes to therapy should be supervised by a qualified clinician to avoid breakthrough seizures.
Common side effects include:
Less common but important adverse effects:
Most side effects are dose-related and may improve with dose adjustments. Never alter your dose on your own; work with your prescriber to optimize efficacy and tolerability.
Levetiracetam has a relatively low interaction profile compared with many antiseizure medications because it is not extensively metabolized by the liver’s cytochrome P450 system. That said, interactions and additive effects can still occur:
Always provide a complete list of prescription drugs, OTC medications, vitamins, and herbal supplements to your healthcare provider to ensure safe co-administration.
If you miss a dose of Keppra, take it as soon as you remember unless it is close to your next scheduled dose. If it’s almost time for the next dose, skip the missed dose and resume your usual schedule. Do not double up to make up for a missed dose, as this can increase side effects. If you miss multiple doses or have a seizure after a missed dose, contact your prescriber for guidance.
Signs of overdose can include profound drowsiness, agitation, confusion, difficulty breathing, and—at very high levels—coma. If an overdose is suspected, call emergency services or go to the nearest emergency department immediately. Supportive care is the mainstay of treatment. Hemodialysis can remove levetiracetam and may be considered in severe cases, especially with renal impairment. Bring the medication bottle or a list of medications to the hospital if possible.
Store Keppra at controlled room temperature (generally 68–77°F or 20–25°C). Keep tablets in a dry place in the original container with the lid tightly closed. Protect from excessive heat and moisture (avoid storing in bathrooms). Keep out of reach of children and pets. For the oral solution, follow the label’s specific storage and “discard after opening” instructions. Do not use the medication past its expiration date, and ask your pharmacist how to dispose of unused or expired medicine properly.

Keppra is an antiepileptic medicine whose active ingredient, levetiracetam, binds to the synaptic vesicle protein SV2A in the brain. This modulates neurotransmitter release and stabilizes neuronal activity, helping prevent seizures. It does not act on the liver’s enzyme system, so it has few drug interactions.
Keppra is used for focal (partial-onset) seizures, primary generalized tonic–clonic seizures, and myoclonic seizures in certain generalized epilepsies. It can be used as monotherapy or add-on therapy in adults and children, depending on the seizure type and local approvals.
A common adult starting dose is 500 mg twice daily, increased by 500 mg twice daily every 2 weeks based on response and tolerability. Many adults respond between 1,000–3,000 mg per day, divided twice daily. Doses must be adjusted in kidney impairment.
Keppra has a rapid onset; some people notice benefit within days as the dose reaches therapeutic levels. Full effect often emerges after dose optimization over several weeks.
The most reported side effects are sleepiness, dizziness, fatigue, irritability, and headache. Some people experience appetite changes or gastrointestinal upset. Serious reactions are uncommon but can include mood changes, agitation, or rare allergic reactions.
Yes. Keppra can cause behavioral changes such as irritability, agitation, anxiety, depression, or rarely aggression. These effects are dose-related in some patients and may improve with dose adjustment, added vitamin B6 in select cases, or switching therapy. Seek medical advice urgently if mood changes are severe or include suicidal thoughts.
Levetiracetam has minimal interactions because it is not significantly metabolized by liver enzymes that many drugs use. It generally does not reduce birth control efficacy and is less affected by other antiepileptics. Always share your medication list with your clinician to check for rare or situation-specific interactions.
Compared with several older antiepileptic drugs, Keppra has relatively reassuring pregnancy data and is often considered when seizure control allows. During breastfeeding, levetiracetam passes into milk but is typically considered compatible; monitor the infant for sedation or poor feeding. Never change seizure medications in pregnancy without specialist guidance.
Alcohol can increase drowsiness and may lower seizure threshold, especially with heavy use. If you drink, do so in moderation and avoid binge drinking. Discuss safe limits with your clinician based on your seizure control and other risk factors.
Take the missed dose as soon as you remember unless it’s close to the next scheduled dose; if so, skip the missed dose and resume your usual schedule. Do not double up doses. Missing doses can increase seizure risk.
Do not stop suddenly, as abrupt discontinuation can trigger seizures. Tapering is usually done gradually over weeks under medical supervision, with a plan tailored to seizure type, duration of seizure freedom, and alternative medications if switching.
Routine blood level monitoring is not typically required for levetiracetam, which simplifies care. Kidney function should be checked periodically, especially in older adults or those with kidney disease, to guide dosing.
Immediate-release levetiracetam is taken twice daily, while Keppra XR (extended-release) allows once-daily dosing for convenience and may smooth out side effects. Total daily doses are similar; your clinician will choose based on adherence, tolerability, and seizure control.
Both are broad-spectrum antiepileptic drugs effective for focal and some generalized seizures. Keppra titrates quickly and has fewer drug interactions; lamotrigine requires slow titration to reduce rash risk but is often better tolerated long term and may improve mood. Behavioral side effects are more common with Keppra, while serious rash risk (including rare SJS) is more associated with lamotrigine.
Valproate is highly effective for generalized epilepsies (including myoclonic and absence) but carries risks such as weight gain, tremor, hair loss, liver toxicity, thrombocytopenia, and major teratogenicity. Keppra has fewer interactions, is generally safer in pregnancy, and is effective for many seizure types, though valproate may be preferred for certain generalized syndromes. Choice depends on seizure type, age, sex, comorbidities, and reproductive plans.
Both treat focal seizures effectively. Carbamazepine is a strong enzyme inducer with many interactions and can cause hyponatremia, blood dyscrasias, and rash; it may worsen some generalized seizure types. Keppra has minimal interactions and broader utility but may cause behavioral symptoms.
Oxcarbazepine is effective for focal seizures and tends to have fewer interactions than carbamazepine but can still cause hyponatremia and rash, and may reduce hormonal contraceptive efficacy at higher doses. Keppra offers broad-spectrum coverage with renal clearance and few interactions, but behavioral side effects may be a limiting factor.
Topiramate is broad-spectrum and also used for migraine prevention; common side effects include cognitive slowing, word-finding difficulty, paresthesias, weight loss, and kidney stones. Keppra generally has fewer cognitive effects but more irritability in some patients. Either can be effective; comorbid conditions (e.g., migraines, weight concerns) often guide the choice.
Both treat focal seizures and are available orally and IV. Lacosamide can prolong PR interval and cause dizziness or ataxia; it has modest interactions and is often well tolerated. Keppra is broader-spectrum with minimal interactions but carries behavioral risks; cost and individual response also influence selection.
Brivaracetam is a higher-affinity SV2A ligand related to levetiracetam and may have fewer behavioral adverse effects for some patients. Efficacy is similar in focal seizures, and dosing is typically twice daily with few interactions; in some regions it is a controlled substance. Patients who develop irritability on Keppra sometimes do better on brivaracetam.
Phenytoin is effective, especially in acute seizure management, but has a narrow therapeutic index, significant drug interactions, and long-term adverse effects (gingival overgrowth, neuropathy, bone loss, cosmetic changes). Keppra is simpler to dose, has few interactions, and is generally better tolerated for chronic use.
Gabapentin has limited efficacy for epilepsy and is more commonly used for neuropathic pain; it causes sedation, dizziness, and weight gain in some users. Keppra is a more potent antiseizure medication with broader indications and a stronger evidence base for seizure control.
Clobazam and other benzodiazepines are effective adjuncts and rescue options but can cause sedation, tolerance, and dependence over time. Keppra is a maintenance antiseizure medication intended for long-term control without tolerance development. They are often used together strategically in refractory epilepsy.
Zonisamide is a once-daily broad-spectrum agent that can cause weight loss, kidney stones, metabolic acidosis, and cognitive effects; it’s a sulfonamide derivative with rare serious rashes. Keppra avoids these metabolic issues but may trigger irritability. Choice depends on side-effect profile and comorbidities.
Perampanel antagonizes AMPA receptors and is effective for focal-onset and primary generalized tonic–clonic seizures. It can cause dizziness and dose-related behavioral changes including irritability and aggression, especially at higher doses. Keppra also carries behavioral risks but has a longer track record, fewer interactions, and renal clearance rather than hepatic metabolism.
Pregabalin has limited use in epilepsy and is mainly prescribed for neuropathic pain and anxiety; side effects include dizziness, edema, and weight gain. Keppra is much more effective for seizure prevention across several types, with a different side-effect profile and minimal interactions.
Ethosuximide is highly specific for absence seizures and is not broadly effective for other seizure types. Keppra is not the first-line choice for pure absence epilepsy but treats focal and several generalized seizures. Drug selection is based on seizure type, age, and tolerability.
Both are commonly considered due to safer pregnancy profiles than valproate. Lamotrigine may require dose adjustments during pregnancy due to changing clearance, and it interacts with estrogen-containing contraceptives; Keppra typically has stable levels and minimal interactions. Individual response and side effects guide the final choice.
