Key Takeaways
Levetiracetam is a seizure medication used to prevent and control epilepsy and certain types of seizures.
Common side effects include dizziness, tiredness, and mood changes, which often improve over time.

This medication may affect mood and behavior, especially in children and teenagers.
Always take levetiracetam exactly as prescribed and never stop without talking to your doctor first.
Keppra (Generic Levetiracetam) Overview
Levetiracetam, commonly known by its brand name Keppra, is an antiepileptic medication used to prevent and control seizures. The generic version contains the exact same active ingredient as the brand-name drug and works in your body the same way. This medication belongs to a class of drugs called anticonvulsants, which help reduce abnormal electrical activity in the brain that causes seizures.
Levetiracetam is prescribed for several types of seizure disorders, including partial-onset seizures, myoclonic seizures, and generalized tonic-clonic seizures. Unlike some older seizure medications, levetiracetam doesn't require frequent blood tests to monitor levels in your body, making it easier to use long-term. The generic version offers a cost-effective alternative to brand-name drugs while providing the same therapeutic benefits and safety profile.
This information is educational and does not replace advice from your healthcare provider. Your doctor will determine if levetiracetam is right for your specific seizure condition and medical history.
Side Effects
Levetiracetam is generally well-tolerated by most people. However, like all medications, it can cause side effects that range from mild to serious. Many side effects decrease in frequency and intensity as your body adjusts to the medication.
Common Side Effects
Dizziness — A spinning sensation or lightheadedness that may affect balance, especially when standing up or moving quickly.
Tiredness or fatigue — Feeling unusually exhausted or lacking energy, even after adequate rest.
Mood changes — Irritability, anxiety, or emotional instability that may occur, particularly during the first few weeks of treatment.
Coordination problems — Difficulty with balance or muscle control that may make physical activities feel clumsy.
Headache — Mild to moderate head pain that usually responds to over-the-counter pain relievers.
Loss of appetite — Reduced interest in eating or feelings of fullness that may lead to slight weight changes.
Serious Side Effects
Severe mood or behavior changes — Thoughts of self-harm, aggression, depression, or personality shifts that develop suddenly and require immediate attention.
Allergic reactions — Rash, hives, swelling of face or throat, or difficulty breathing, which are rare but require emergency care.
Severe coordination problems — Significant loss of balance, inability to control movements, or tremors that interfere with daily activities.
Suicidal thoughts — Increased risk of suicidal ideation, especially in people with a history of mental health conditions or depression.
Severe skin reactions — Blistering, peeling, or widespread rashes that may indicate a serious allergic response.
When to Seek Medical Attention
If you experience mood or behavior changes, especially thoughts of harming yourself, contact your doctor or mental health professional right away. Suicidal thoughts can occur with seizure medications, but this risk can be managed with proper monitoring and support.
Seek emergency medical care if you develop signs of an allergic reaction (rash, swelling, difficulty breathing), severe dizziness that prevents you from functioning safely, or any symptom that feels dangerous or uncontrollable. Most side effects improve with time, but your doctor needs to know about persistent or bothersome effects so adjustments can be made.

Important: Never stop taking levetiracetam without talking to your doctor first, as suddenly stopping the medication may cause breakthrough seizures. If you miss a dose, take it as soon as you remember, but skip it if your next dose is coming up soon. Do not take two doses at once to make up for a missed dose. Always refill your prescription before you run out to avoid gaps in treatment.
Drug Interactions
Levetiracetam has relatively few drug interactions compared to older seizure medications, but certain substances can still affect how it works or increase your risk of side effects. Always tell your doctor and pharmacist about all medications, supplements, and herbal products you're taking before starting levetiracetam.
Oral Contraceptives
Levetiracetam does not reduce the effectiveness of birth control pills, unlike some older seizure medications. However, hormonal changes from oral contraceptives may occasionally affect seizure control, so monitor your seizure patterns closely.
Alcohol
Combining alcohol with levetiracetam increases dizziness, drowsiness, and impaired coordination. Avoid alcohol or limit it significantly while taking this medication to prevent dangerous side effects.
Other Seizure Medications
Taking levetiracetam with other anticonvulsants generally works well and is often done intentionally for better seizure control. However, your doctor must monitor you carefully to avoid excessive drowsiness or coordination problems.
NSAIDs and Pain Relievers
Common pain relievers like ibuprofen or naproxen are generally safe with levetiracetam. However, high doses or prolonged use may increase the risk of kidney problems, especially if you already have reduced kidney function.
Methotrexate
This cancer and autoimmune medication may increase levetiracetam levels in your blood, raising the risk of side effects. Your doctor may need to adjust your levetiracetam dose if you take methotrexate.
Corticosteroids
Using corticosteroids with levetiracetam may affect mood and behavior changes. Inform your doctor if you take steroids so they can monitor you for unusual mood shifts or behavioral issues.

Frequently Asked Questions
Get answers to common questions about Keppra (generic levetiracetam).
Most people begin experiencing reduced seizure frequency within the first week to two weeks of starting levetiracetam. However, optimal seizure control may take 4–8 weeks as your doctor adjusts the dose. Seizures may stop completely for some people, while others experience a significant reduction in how often they occur. Talk to your doctor about realistic expectations for your specific situation.
Yes, generic levetiracetam contains the exact same active ingredient as brand-name Keppra and works identically in your body. The FDA requires generic medications to meet the same strict safety and effectiveness standards as brand-name versions. Understanding the differences between generic and brand-name drugs can help you make informed decisions about your medication while saving money.
Never stop taking levetiracetam without your doctor's approval, even if your seizures have stopped. Suddenly stopping this medication can trigger severe seizures or status epilepticus (prolonged, dangerous seizures). If you and your doctor decide to stop treatment, the dose must be reduced gradually over weeks or months under medical supervision to safely discontinue the medication.
Take the missed dose as soon as you remember, unless your next scheduled dose is within a few hours. If your next dose is approaching, skip the missed dose and continue on your regular schedule. Never double-dose to make up for a missed amount. Set a phone alarm or use a pill organizer to help remember your doses and maintain consistent seizure control.
Levetiracetam can be taken with or without food, and food does not affect how well it works. However, you should avoid alcohol, as it increases dizziness and drowsiness. Stay well-hydrated and maintain a balanced diet to support overall health and medication effectiveness. If stomach upset occurs when taking the medication, eating a light snack may help.
The Bottom Line
Levetiracetam (generic Keppra) is an effective, well-tolerated seizure medication that works for many types of epilepsy and seizure disorders. While mood changes and dizziness are possible side effects, they often improve with time and proper dose management. The generic version provides the same reliable seizure control as brand-name Keppra at a lower cost, making it an accessible option for long-term treatment. Your doctor will work with you to find the right dose and monitor your progress to ensure you're getting the maximum benefit with minimal side effects. If you have questions about whether levetiracetam is right for you, or if you need guidance managing side effects, don't hesitate to reach out to your healthcare provider.
