Hi, The drug you took from the pharmacist has the same drug but of different manufacturer, its unlikely to cause the seizure
because its the same drug. As the drug companies maintain the standards of manufacturing drug and have proper license and scrutiny its less likely for the newer company drug to have caused seizure. You need to consult your doctor to find out what has caused recurrence of seizure. The pharmacist should not change the prescription either the drug or the company prescribed without doctors permission.
