A 10 y old pt.known dm1recently dx. epilepsy started on keppra (levetiracetam) 2 days later expereined severe hypoglycemia (insulin stopped 4 aweek) any explaination?

Possibly Keppra (levetiracetam): Hypoglycemia has been reported to fda by very low number of users (0.39% of those reporting side effects). I have not found any suggested explanation for this side effect.

Anorexia???: Keppra (levetiracetam) induced hypoglycemia is well known in literature. It's hypoglycemic effect happens more often in beginning of treatment and more frequently in females.
