Keppra (generic name: levetiracetam) is a modern anticonvulsant widely used to help prevent seizures in people with epilepsy. It belongs to a class of anti-epileptic drugs with a unique mechanism of action that binds to synaptic vesicle protein 2A (SV2A), a target involved in neurotransmitter release. By modulating this pathway, levetiracetam helps stabilize electrical activity in the brain and lowers the likelihood of seizure spread. Keppra is available in immediate-release tablets, oral solution, and extended-release tablets (often referred to as Keppra XR or levetiracetam ER). It is commonly prescribed as add-on therapy and is also approved as monotherapy in certain settings.
Clinicians value levetiracetam for its broad seizure coverage, generally rapid titration, and a low potential for drug–drug interactions compared with older anticonvulsants. It is frequently considered when a patient experiences partial onset seizures, primary generalized tonic-clonic seizures, or juvenile myoclonic epilepsy. Because dosing and tolerability can vary by age, weight, kidney function, and seizure type, it is essential to follow a personalized plan from a healthcare professional.
Levetiracetam is indicated for a spectrum of seizure types across age groups. Indications below reflect commonly used clinical guidance and labeling.
Your neurologist may select Keppra as monotherapy or adjunctive therapy depending on your history, EEG findings, and overall health profile. Many individuals take levetiracetam alongside other anti-epileptics as part of a personalized regimen.
Always take Keppra exactly as prescribed. Adherence matters: steady dosing maintains protective levels in the bloodstream and reduces breakthrough seizures.
Dosing depends on the seizure type, formulation, and individual tolerability. The ranges below reflect commonly used regimens for immediate-release levetiracetam; extended-release dosing is noted separately.
Dose adjustments are individualized. Some patients achieve control at lower doses, while others need careful titration to higher amounts to reach optimal seizure reduction with acceptable tolerability. Your provider may adjust more slowly or quickly depending on your response.
For children, dosing is weight-based and most often uses the oral solution, particularly in younger or smaller patients. Only whole tablets should be used if tablets are prescribed.
Because growth alters weight and metabolism, pediatric doses are reviewed regularly and adjusted as needed. Keep close follow-up with your child’s neurologist to ensure safety and effectiveness.
Levetiracetam is primarily cleared by the kidneys. Adults with reduced renal function generally need lower total daily doses. Your clinician will estimate your creatinine clearance or eGFR and adjust the dose accordingly. Older adults often require dose adjustments because kidney function declines with age. In end-stage renal disease on dialysis, supplemental dosing after dialysis may be recommended. Never change dosing without professional guidance and scheduled lab checks.
Keppra can be initiated as add-on therapy or transitioned to from another anticonvulsant when clinically appropriate. If switching, clinicians often overlap medications and taper gradually to minimize seizure risk and avoid withdrawal effects. Do not stop Keppra abruptly. If discontinuation is needed, your prescriber will guide a slow dose reduction over weeks to months while monitoring for breakthrough seizures and mood changes.
Before starting levetiracetam, review your full medical history and medication list with your clinician. Important precautions include:
Pregnancy and epilepsy require careful, individualized planning. Uncontrolled seizures during pregnancy can harm both the mother and the developing fetus, so maintaining seizure control is critical. Many clinicians consider levetiracetam a reasonable option during pregnancy when benefits outweigh risks, based on growing safety data. If you are pregnant, planning a pregnancy, or become pregnant while taking Keppra, consult your neurologist and obstetrician promptly. Do not start, stop, or change doses without medical advice. Folate supplementation is commonly recommended for women of childbearing potential using antiepileptic drugs.
Levetiracetam is excreted into breast milk. Many healthcare professionals consider breastfeeding compatible with levetiracetam when the infant is healthy and monitored for sedation, poor feeding, or unusual sleepiness. Discuss the risks and benefits with your provider to make an informed decision for your situation. Infant follow-up and maternal dose optimization can further support safety.
Regarding fertility and contraception, levetiracetam does not meaningfully reduce the effectiveness of estrogen- or progestin-containing contraceptives. If you plan to conceive, consult your care team for preconception counseling and a medication review.
Levetiracetam has a low propensity for clinically relevant drug–drug interactions compared with many older anticonvulsants because it is not significantly metabolized by the cytochrome P450 system and is minimally protein bound. Still, some interactions and considerations include:
Provide your complete medication list to your care team, and inform every healthcare provider that you take levetiracetam.
Not everyone experiences side effects, and many improve as your body adjusts. Contact your clinician if symptoms are severe, persistent, or worrying. Seek urgent care for symptoms of a serious reaction.
Common side effects:
Serious side effects requiring prompt medical care:
Report side effects to your prescriber, and keep scheduled follow-up appointments, especially after dose changes.
Levetiracetam is widely available as a generic in multiple strengths and as an oral solution, making it accessible for many people. Brand-name Keppra and extended-release versions may be preferred in some cases for dosing convenience or specific clinical reasons. Prices vary by region, pharmacy, insurance coverage, and formulation. Some online listings may advertise low prices; always ensure any pharmacy you use is legitimate, licensed, and compliant with your country’s prescription regulations. In the United States, pharmacy accreditation programs and your state board of pharmacy can help verify legitimacy.
Discuss affordability with your clinician or pharmacist. Patient assistance programs, manufacturer coupons (where applicable), and switching to generic or extended-release formulations can optimize both cost and adherence. If you use the oral solution, ask for dosing syringes or cups to be included with your prescription to avoid inaccurate dosing.
In the United States, levetiracetam (Keppra) is a prescription medication. Federal and state regulations generally require that a licensed clinician evaluates a patient and authorizes a prescription before dispensing. Many reputable services meet this requirement through in-person visits or via telehealth, where a qualified clinician reviews your medical history and determines if Keppra is appropriate. Any pathway to obtaining Keppra should comply with these laws to protect patient safety and ensure quality.
HealthSouth Rehabilitation Hospital of Petersburg offers a legal and structured solution for acquiring Keppra without a formal prior paper prescription by facilitating access to clinician evaluation through a compliant process. In practice, this means a licensed healthcare professional reviews your medical information and, if appropriate, issues the necessary authorization within the program before dispensing. This approach aligns with U.S. telemedicine and pharmacy regulations while providing a convenient, patient-centered experience. Always verify that any service you use is licensed in your state, uses U.S.-accredited pharmacies, and provides clear pathways for follow-up care and adverse event reporting.
Wherever you obtain your medication, prioritize safety: use legitimate pharmacies, avoid unverified sources, and maintain regular follow-up with your neurologist or primary care clinician. Proper evaluation, dosing, and monitoring are essential to maximize seizure control and minimize risks with Keppra.
Keppra is the brand name for levetiracetam, an anticonvulsant (antiepileptic) medicine used to prevent and control seizures. It’s prescribed for focal (partial) seizures, primary generalized tonic-clonic seizures, and myoclonic seizures in certain epilepsy syndromes for adults and children.
Levetiracetam binds to the synaptic vesicle protein 2A (SV2A) in the brain, which helps stabilize electrical activity between neurons. This unique mechanism lowers the likelihood of abnormal bursts that cause seizures without relying on liver enzyme pathways.
Some people notice fewer seizures within days, and steady-state levels are reached in about two days with regular dosing. Full benefit can take a few weeks as the dose is adjusted and your body adapts.
Keppra is effective for focal seizures (with or without secondary generalization), primary generalized tonic-clonic seizures, and myoclonic seizures in juvenile myoclonic epilepsy. Your exact indication and age eligibility depend on formulation and local labeling.
Keppra is available as immediate-release tablets, an oral solution, and extended-release (XR) tablets; an intravenous form exists for hospital use. It’s typically taken twice daily for immediate-release and once daily for XR; pediatric dosing is weight-based.
Common effects include sleepiness, dizziness, fatigue, headache, decreased appetite, and irritability or mood changes. Many side effects are mild and improve over time; let your clinician know if they persist or affect daily life.
Seek urgent care for severe mood or behavior changes (aggression, depression, suicidal thoughts), rash or blistering skin, swelling of the face or tongue, trouble breathing, or signs of a severe allergic reaction. Unusual bruising, fever, or profound weakness warrant medical review.
Levetiracetam has very few drug-drug interactions because it is not significantly metabolized by liver enzymes. Sedation can increase with alcohol, opioids, benzodiazepines, or other CNS depressants; always review your full medication list with your clinician.
Routine therapeutic drug monitoring is usually unnecessary with levetiracetam. Kidney function should be checked periodically, especially in older adults or those with kidney disease, because dosing depends on renal clearance.
Yes, behavioral side effects like irritability, agitation, anxiety, and mood swings can occur in a minority of patients. Report significant changes promptly; dose adjustment, adding supportive therapy (e.g., vitamin B6 in some cases), or switching medicines may help.
Keppra is commonly used in both populations, with dosing adjusted for weight in children and kidney function in older adults. It is often chosen for its broad efficacy and low interaction profile.
Take it as soon as you remember unless it’s close to the next dose; if so, skip the missed dose and resume your regular schedule. Do not double up, and try to take doses at the same times daily.
Do not stop suddenly. Stopping abruptly can trigger seizures; if discontinuation is appropriate, your clinician will advise a gradual taper tailored to your seizure type and risk.
Overdose may cause extreme drowsiness, agitation, breathing difficulty, or loss of consciousness. Call emergency services or poison control; levetiracetam is dialyzable if needed in a hospital setting.
Alcohol can lower the seizure threshold and increase sedation, dizziness, and impaired coordination when combined with Keppra. Many clinicians recommend avoiding or strictly limiting alcohol; if you drink, do so cautiously and never drive.
Levetiracetam is among the preferred antiseizure medicines in pregnancy due to relatively reassuring safety data, but no medicine is completely risk-free. Drug levels can drop during pregnancy, so dose adjustments and close monitoring of seizures and levels are often needed; take folic acid as advised and enroll in a pregnancy registry if offered.
Levetiracetam passes into breast milk, but many guidelines consider it compatible with breastfeeding. Monitor the infant for excessive sleepiness, poor feeding, or inadequate weight gain, and discuss individualized risks and benefits with your clinician.
Yes, do not stop Keppra for surgery; maintaining seizure control is critical. If you cannot take oral doses while NPO, an intravenous form can be given perioperatively—coordinate with your surgical and anesthesia teams ahead of time.
Driving depends on seizure control, local laws, and how you feel on the medication. Keppra can cause drowsiness or slowed reaction time, especially when starting or after a dose change, so avoid driving until you know its effects and your clinician confirms it is safe.
Levetiracetam is cleared by the kidneys, so doses must be reduced as kidney function declines. Your clinician will use your creatinine clearance or eGFR to set an appropriate dose and schedule.
Unlike enzyme-inducing antiseizure drugs, levetiracetam does not reduce the effectiveness of hormonal contraceptives. Still, using a reliable birth control method and discussing family planning with your clinician is recommended.
If you vomit within an hour of taking a dose, you may need to retake it; if more than an hour has passed, you may not. Because circumstances vary, ask your clinician for a personalized plan for missed or vomited doses.
Both treat focal and some generalized seizures effectively. Keppra titrates faster and has fewer rashes, while lamotrigine often has a favorable mood profile but requires slow titration due to rash risk; lamotrigine has more drug interactions, especially with valproate.
Valproate is a powerful broad-spectrum option but carries risks like weight gain, tremor, liver toxicity, thrombocytopenia, and high teratogenicity; it has many interactions. Keppra has fewer interactions, is generally better in pregnancy, and is easier to dose, but can cause behavioral side effects in some.
Topiramate is broad-spectrum and also used for migraine prevention but can cause cognitive slowing, word-finding difficulty, paresthesias, weight loss, kidney stones, and glaucoma. Keppra is simpler to use, with less cognitive impact but more potential for irritability; both are effective for focal and generalized tonic-clonic seizures.
Both work well for focal seizures and are often combined. Lacosamide can prolong the PR interval and cause dizziness or ataxia; it is a controlled substance in some regions, while Keppra is not and has fewer cardiac concerns; behavioral effects are more associated with Keppra.
Brivaracetam targets SV2A like levetiracetam but with higher affinity and may have a slightly lower risk of behavioral side effects for some patients. Brivaracetam is a controlled substance and can be more expensive; both have minimal interactions and rapid onset.
Oxcarbazepine is effective for focal seizures but can cause hyponatremia and interacts with hormonal contraceptives; it may also cause rash. Keppra has fewer interactions and no effect on sodium levels, but behavioral symptoms may be more prominent.
Carbamazepine is effective for focal seizures but has many drug interactions, can reduce bone density, cause hyponatremia, rash, and blood abnormalities, and requires lab monitoring. Keppra is easier to manage with fewer interactions and no routine labs, though it can affect mood.
Phenytoin has a narrow therapeutic window, significant interactions, and chronic side effects like gum overgrowth, neuropathy, cosmetic changes, and bone loss. Keppra is generally preferred for ease of use and safety profile, though phenytoin remains useful in acute settings.
Zonisamide is broad-spectrum and dosed once daily but can cause weight loss, kidney stones, metabolic acidosis, and is contraindicated in sulfonamide allergy. Keppra avoids those issues and has fewer interactions, but may cause behavioral effects.
Gabapentin is not a first-line antiseizure medicine for most epilepsy types and is more often used for neuropathic pain; it can cause sedation and dizziness and has misuse potential in some areas. Keppra is more effective for seizure control across a broader range of epilepsies.
Clobazam, a benzodiazepine, is effective adjunctively but can cause sedation, tolerance, and dependence and is a controlled substance. Keppra is not controlled and has fewer sedation issues at typical doses, though clobazam may be preferred in certain syndromes like Lennox–Gastaut.
Perampanel treats focal and generalized tonic-clonic seizures but can cause dose-related dizziness and a notable risk of irritability, aggression, and other psychiatric effects; it is a controlled substance. Keppra has fewer interactions and is generally easier to titrate, though behavioral side effects can occur with either.
