My Friend Is Hospitalized For Grand Mal Seizures. Started Wed.

My friend is hospitalized for grand mal seizures. Started Wed. after getting a cortisone shot in shoulder. Doctor may have missed the mark with the shot. My friend is 62, on Keppra. Was ready to come home yesterday when they increased the dosage from 2000 mg to 3000 mg. I am concerned since he had more seizures after the increase in Keppra. Lin
