What it is used for
- Epilepsy (several seizure types, alone or with other medicines)
How it works
Levetiracetam is thought to work by binding to a protein in nerve endings that influences how nerve signals are released, helping to reduce abnormal electrical activity that causes seizures.
How it is taken
Usually available as tablets, an oral liquid and an injection used in hospital. It is taken by mouth, usually with the amount built up gradually. Take it exactly as your doctor or pharmacist directs and follow the label; do not stop suddenly, as this can trigger seizures.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
