Brand name:

Felbatol

Why is Felbatol prescribed?

Felbatol, a relatively new epilepsy medication, is used alone or with other drugs to treat partial seizures with or without generalization (seizures in which consciousness may be retained or lost). It is also used with other medications to treat seizures associated with Lennox-Gastaut syndrome (a childhood condition characterized by brief loss of awareness and muscle tone).

Felbatol is prescribed only when other medications have failed to control severe cases of epilepsy.

Most important fact about Felbatol

When taking Felbatol, be alert for signs of a very rare but dangerous side effect called aplastic anemia, in which the red blood cell count declines drastically. Warning signs include weakness, fatigue, and a tendency to easily bruise or bleed.

Felbatol has also been known to cause fatal cases of liver failure. Warning signs of a liver problem include dark urine, loss of appetite, stomach upset, and yellow skin or eyes. Alert the doctor immediately if you develop these symptoms. The sooner Felbatol is discontinued, the better your chances of recovery.

How should you take Felbatol?

Take Felbatol exactly as prescribed by your doctor. Felbatol should not be stopped suddenly. This could increase the frequency of your seizures.

If you are taking Felbatol liquid, shake well before using.

--If you miss a dose...

Take the forgotten dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take a double dose.

--Storage instructions...

Felbatol should be stored in a tightly closed container, at room temperature, away from excessive heat and moisture.
