WHY is this medicine prescribed?

Levetiracetam injection is used alone and along with other medications to control partial-onset seizures (seizures that involve only one part of the brain) in adults, children, and infants 1 month of age who cannot take oral medications. Levetiracetam injection is also used in combination with other medications to treat seizures in adults and children 12 years of age or older with juvenile myoclonic epilepsy who cannot take oral medications. Levetiracetam injection is also used in combination with other medications to treat primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) in adults and children 6 years of age or older with epilepsy who cannot take oral medications. Levetiracetam is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.

HOW should this medicine be used?

Levetiracetam injection comes as a solution (liquid) to be injected intravenously (into a vein) over a period of 15 minutes. It is usually given twice a day for as long as you are unable to take levetiracetam tablets or oral solution by mouth.

You may receive levetiracetam injection in a hospital or you may use the medication at home. If you will be receiving levetiracetam injection at home, a nurse or a healthcare provider may come to your home to perform the injection or your healthcare provider will show you how to use the medication. Carefully read the manufacturer's instructions for use that comes with the medication. These instructions describe how to mix and inject a dose of levetiracetam injection. Be sure to ask your pharmacist or doctor if you have any questions.

Your doctor will probably start you on a low dose of levetiracetam and gradually increase your dose, not more often than once every 2 weeks.

Levetiracetam may help control your condition but will not cure it. Continue to use levetiracetam even if you feel well. Do not stop using levetiracetam injection without talking to your doctor, even if you experience side effects such as unusual changes in behavior or mood. If you suddenly stop using levetiracetam injection, your seizures may become worse. Your doctor will probably decrease your dose gradually.

Are there OTHER USES for this medication?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

A small number of adults and children 5 years of age and older (about 1 in 500 people) who took anticonvulsants such as levetiracetam to treat various conditions during clinical studies became suicidal during their treatment. Some of these people developed suicidal thoughts and behavior as early as one week after they started taking the medication. There is a risk that you may experience changes in your mental health if you take an anticonvulsant medication such as levetiracetam, but there may also be a risk that you will experience changes in your mental health if your condition is not treated. You and your doctor will decide whether the risks of taking an anticonvulsant medication are greater than the risks of not taking the medication. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: panic attacks; agitation or restlessness; nervousness, new or worsening irritability, anxiety, or depression; acting on dangerous impulses; difficulty falling or staying asleep; aggressive, angry, or violent behavior; mania (frenzied, abnormally excited mood); talking or thinking about wanting to hurt yourself or end your life; withdrawing from friends and family; preoccupation with death and dying; giving away prized possessions; or any other unusual changes in behavior or mood.
