What is the procedure for weaning off anti epileptic drugs, specifically keppra (levetiracetam)?

With Your Doctor. Weaning off of Keppra (levetiracetam) will depend on the dosage and length of time on the medication. It would be tapered down, much the same as it is generally started. Because of complications, it should only be done under your doctor's supervision. It is not something to try on your own at home.
Depends on patient. The weaning process is highly individualized, based on your personal seizure history and the specific medications involved. For example, Keppra (levetiracetam) can often be weaned to off in a matter of weeks (or even mmediately, in the case of a patient who had been well controlled on very low doses), while Phenobarbital can take months to come off completely.
