Levetiracetam is used to treat seizures (epilepsy). It
belongs to a class of drugs known as anticonvulsants. Levetiracetam may
decrease the number of seizures you have.
Read the Medication Guide and, if available, the Patient
Information Leaflet provided by your pharmacist before you start taking
levetiracetam and each time you get a refill. If you have any questions,
ask your doctor or pharmacist.
Take the liquid and regular-release tablets by mouth as
directed by your doctor, usually twice daily with or without food. Crushing
or chewing the tablet may cause a bitter taste.
If you are using the liquid form of this medication,
carefully measure the dose using a special measuring device/spoon. Do not
use a household spoon because you may not get the correct
dose.
If you are using the extended-release tablets, take this
medication as directed by your doctor, usually once daily. Swallow the
extended-release tablets whole. Do not crush or chew the tablets. Doing so
can release all of the drug at once, increasing the risk of side
effects.
The dosage is based on your medical condition and
response to treatment. Children's dosage is also based on weight. To reduce
your risk of side effects (such as dizziness and drowsiness), your doctor
may direct you to start this medication at a low dose and gradually
increase your dose. Follow your doctor's instructions
carefully.
Use this medication regularly to get the most benefit
from it. To help you remember, take it at the same times each
day.
Do not increase your dose or use this drug more often or
for longer than prescribed. Your condition will not improve any faster, and
your risk of side effects will increase.
Do not stop taking this medication without consulting
your doctor. Your seizures may become worse when the drug is suddenly
stopped. Your dose should be gradually decreased.
Tell your doctor if your seizures lasts, change, or gets
worse.
Drowsiness, dizziness, unusual tiredness, or weakness
may occur. These side effects are more common during the first 4 weeks and
usually lessen as your body adjusts to the medication. If any of these
effects last or get worse, tell your doctor or pharmacist
promptly.
Remember that this medication has been prescribed
because your doctor has judged that the benefit to you is greater than the
risk of side effects. Many people using this medication do not have serious
side effects.
Tell your doctor right away if you have any serious side
effects, such as:
- loss of coordination (such as difficulty walking and
controlling muscles)
- mental/mood changes (such as irritability, aggression,
agitation, anger, anxiety)
- signs of anemia (such as unusual tiredness that doesn't go
away, pale skin, fast breathing, fast heartbeat)
- easy bruising/bleeding
A small number of people who take anticonvulsants for
any condition (such as seizures, bipolar disorder, pain) may experience
depression, suicidal thoughts/attempts, or other mental/mood problems. Tell
your doctor right away if you or your family/caregiver notice any
unusual/sudden changes in your mood, thoughts, or behavior including signs
of depression, suicidal thoughts/attempts, thoughts about harming
yourself.
Levetiracetam can commonly cause a rash that is usually
not serious. However, you may not be able to tell it apart from a rare rash
that could be a sign of a severe reaction. Tell your doctor right away if
you develop any rash.
