Felbamate Oral Warning
Severe (sometimes fatal) blood disorders (aplastic anemia, pancytopenia) and liver problems have occurred with felbamate. Felbamate should be used only in people with severe seizures (epilepsy) that cannot be controlled with other medications. This drug should not be used if you have liver problems. Discuss the risks and benefits with your doctor before starting felbamate.
Immediately tell your doctor if you have symptoms of infection (fever, chills, persistent sore throat), anemia (tiredness, pale skin/fingernails, fast heartbeat), liver problems (e.g., severe stomach/abdominal pain, unusual weakness/tiredness, pale stools, dark urine, yellowing eyes/skin) or if you have unusual bleeding/bruising. Usually, people who have liver problems while taking this drug should not start taking it again.
Your doctor will perform certain blood tests (e.g., liver function, complete blood count) and may have you see a doctor who treats blood problems (hematologist) before you start felbamate and while you use this drug. Aplastic anemia may occur after you stop taking the drug. Therefore, blood tests may be needed for some time after you stop taking it. Keep all medical/laboratory appointments.
