Levetiracetam: Uses, Side Effects & Safety

What it is and what it's used for

Levetiracetam belongs to a group of medicines called antiepileptics (anti-seizure medicines). It is used to treat epilepsy in adults and children. It is commonly prescribed for partial (focal) seizures, and for some types of generalised seizures such as myoclonic seizures and tonic-clonic seizures, often alongside other anti-seizure medicines. In some cases it is also used as a first-line treatment on its own.

Levetiracetam is a prescription-only medicine in India and is never used without a doctor's supervision. Epilepsy treatment usually continues for a long time — often years — and the dose is adjusted by the doctor based on how well seizures are controlled and how the patient tolerates the medicine.

How it works (simple language)

Seizures happen when electrical activity in the brain becomes sudden, excessive, and uncontrolled. Levetiracetam works by binding to a protein on nerve cells called SV2A, which is involved in releasing chemical signals between nerve cells. It is thought to calm down the abnormal firing of brain cells in this way, making seizures less likely to start and spread.

Scientists are still studying the exact details, but clinical experience shows it is effective for many people, and it has the advantage of causing fewer interactions with other medicines than some older anti-seizure medicines.

Dosage forms available in India (general info only)

Levetiracetam is commonly available in India as film-coated tablets in strengths such as 250 mg, 500 mg, 750 mg and 1000 mg, as extended-release tablets (e.g. brand names like Levera, Torleva, Keppra XR-type formulations), and as an oral solution for children and people who cannot swallow tablets. An injectable form exists for hospital use. Well-known brand names in India include Keppra, Levera, and Torleva — brands vary by pharmacy and region.

Never decide the dose yourself from this article. Always follow your doctor's prescription or the directions on the pack, and check with your pharmacist if you are unsure — especially for children, where the dose depends on the child's weight and age.

Side effects

Common: Drowsiness, unusual tiredness or weakness, headache, dizziness, irritability, anxiety or mood changes, loss of appetite, nasal congestion or cold-like symptoms, and double vision (rarely).

Serious — seek medical care: New or worsening depression, suicidal thoughts, aggression, hallucinations or unusual behaviour; severe skin rash, blistering or peeling skin (may signal a serious allergic reaction such as Stevens-Johnson syndrome); difficulty breathing or swelling of the face/lips/tongue; severe weakness with fever (possible blood disorder). These are uncommon but need immediate medical attention.

Precautions and warnings

• Never stop suddenly. Stopping levetiracetam abruptly can trigger seizures, even in people who have not had one for a long time. Any change must be tapered slowly under a doctor's supervision.
• Report mood or behaviour changes. Levetiracetam can cause irritability, anxiety, depression, or aggression in some people, including children. Family members should watch for these and inform the doctor.
• Avoid alcohol. Alcohol can increase drowsiness and may make seizures more likely. Ask your doctor before consuming any alcohol.
• Driving and alertness. Do not drive, ride a two-wheeler, or operate machinery until you know how the medicine affects your alertness.
• Kidney problems. The dose may need to be lower in people with kidney disease — always tell your doctor about kidney problems.
• Missed doses. If you miss a dose, take it as soon as you remember unless it is nearly time for the next one. Never take a double dose. Do not miss doses — regular timing is what keeps seizures away.
• Tell every doctor. Mention that you take levetiracetam before any surgery or when starting a new medicine.

Interactions (general)

Levetiracetam has fewer drug interactions than many older anti-seizure medicines, but interactions can still occur. Other medicines that cause drowsiness (such as sleeping pills, certain painkillers, or anti-anxiety medicines) can add to the drowsiness. Alcohol should be avoided. Always tell your doctor about ALL medicines you take, including herbal and ayurvedic products, because some of them can lower the seizure threshold.

Pregnancy and breastfeeding (general guidance)

If you are pregnant, planning pregnancy, or breastfeeding, consult your doctor before starting or continuing levetiracetam. Epilepsy medicines can carry risks for the baby, but uncontrolled seizures during pregnancy are also dangerous. The doctor will weigh the risks and choose the safest option. Do not stop the medicine on your own because you are pregnant — talk to your doctor first.

Storage

Store at room temperature, away from moisture and direct sunlight. Keep the oral solution bottle tightly closed and check the pack for how long it stays good after opening. Keep all medicines out of the reach of children. Do not use after the expiry date printed on the pack.

When to see a doctor

See a doctor if: seizures continue or get worse after starting the medicine; you notice new mood changes, depression, or unusual behaviour in yourself or your child; you develop a rash or blistering skin; you have unusual bruising or bleeding, persistent fever, or extreme weakness. Seek emergency care for a seizure lasting more than 5 minutes, repeated seizures without regaining consciousness between them, or trouble breathing after a seizure.

FAQs

1. Can I stop taking levetiracetam once my seizures stop?

No — never stop on your own, even if you feel fine and have been seizure-free for months or years. Stopping suddenly can bring seizures back, sometimes worse than before. Doctors usually continue treatment for years and taper the dose very slowly only when it is safe to do so.

2. Does levetiracetam make you sleepy?

Drowsiness and tiredness are among the most common side effects, especially during the first few weeks. For most people this improves with time. Avoid driving and operating machinery until you know how you react.

3. Is levetiracetam safe for children?

Yes, it is commonly prescribed for children with epilepsy, and an oral solution form is available for them. The child's dose is calculated by weight and adjusted by the doctor. Parents should watch for mood or behaviour changes and report them.

4. Can I drink alcohol while taking levetiracetam?

It is best to avoid alcohol. Alcohol can increase the drowsiness caused by the medicine and may trigger seizures, which defeats the purpose of the treatment. Discuss this honestly with your doctor.
