Felbamate may also cause liver damage. Call your doctor if you have symptoms such as
loss of appetite, stomach pain, or jaundice (yellowing of the skin or eyes).

behavior changes, depression, anxiety, or if you feel agitated, hostile, restless, hyperactive
(mentally or physically), or have thoughts about suicide or hurting yourself.
Do not stop taking felbamate without first talking to your doctor, even if you feel
better. You may have increased seizures if you stop taking felbamate suddenly. You will need to
use less and less before you stop the medication completely.

felbamate.
Carry an ID card or wear a medical alert bracelet stating that you are taking

What is felbamate?
Felbamate is an anti-epileptic medication, also called an anticonvulsant.
Felbamate is used alone or in combination with other medications to treat seizures in
adults with epilepsy. Felbamate is also used to treat children with Lennox-Gastaut syndrome, a
severe form of childhood epilepsy that also causes developmental and behavior problems.
Felbamate is usually given after other seizure medications have been tried without
successful treatment of symptoms.
Felbamate may also be used for other purposes not listed in this medication guide.
What should I discuss with my healthcare provider before taking felbamate?
Felbamate can cause serious side effects and is usually given only to people with severe
epilepsy when the need for seizure control outweighs the risk of side effects. You may be asked
to sign a consent form after you and your doctor have discussed the risks and benefits of taking
felbamate.
You should not use this medication if you are allergic to felbamate, or if you have
liver disease or a history of blood cell disorders such as
anemia.
Before taking felbamate, tell your doctor if you are allergic to any drugs or if you have
kidney disease. If you have any of these conditions, you may need a dose adjustment or special
tests to safely take felbamate.
You may have thoughts about suicide while taking this medication. Tell your doctor if
you have new or worsening depression or suicidal thoughts during the first several months of
treatment, or whenever your dose is changed.
Your family or other caregivers should also be alert to changes in your mood or
symptoms. Your doctor will need to check you at regular visits. Do not miss any scheduled
appointments.
