Levetiracetam (brand name Keppra) is a common anti-seizure drug. Doctors prescribe it for many types of epilepsy in adults and kids. It works differently than older drugs and usually needs fewer blood tests. Still, it’s a real medicine with real side effects, so you should know the basics before you start.
Most people take levetiracetam as tablets, extended‑release tablets, or liquid. There’s also an IV form used in hospitals. Typical starting doses for adults are 500 mg twice a day. Your doctor may increase the dose stepwise to control seizures. Many adults end up on 1,000–3,000 mg per day total, split into two doses. Kids get a dose based on weight. If you have kidney problems, doses must be lowered — tell your doctor about any kidney disease.
Levetiracetam works well with other seizure medicines. It doesn’t rely on the liver’s CYP enzymes, so it causes fewer drug interactions than many older anticonvulsants. Still, avoid suddenly stopping it — that can cause more seizures. If you need to stop, your doctor will help you taper off slowly.
The most common side effects are sleepiness, dizziness, tiredness, and weak coordination. Some people notice mood changes: irritability, anxiety, depression, or rare aggressive behavior. If you or a family member notices new or worsening mood problems or suicidal thoughts, contact your prescriber right away.
Other issues can include headaches, nausea, and mild infection risk. Serious allergic reactions are uncommon but possible — seek urgent care for rash, swelling, or trouble breathing. Because levetiracetam is cleared by the kidneys, doctors check kidney function sometimes, especially in older adults.
Alcohol and other sedatives can make dizziness and drowsiness worse. Try to avoid heavy drinking while on levetiracetam and be careful driving until you know how it affects you.
If you miss a dose, take it as soon as you remember unless it’s almost time for the next dose. Don’t double up to catch up without asking your doctor.
Buying online? Only purchase levetiracetam from licensed pharmacies that require a prescription. Cheap pill ads can be risky — fake or poor-quality meds are real dangers. Use sites with clear contact info, pharmacist support, and secure checkout. When in doubt, ask your healthcare team for a trusted source.
