How long before an EEG should medications be stopped?

Patient's question:

Seizures caused by hypoxic brain injury, how long before stopping medication before an electroencephalogram (EEG)?

Doctor's answer:

Hello, based on your description, it may be convulsions caused by hypoxic brain damage. If there are no further episodes, this medication should not be used continuously. Additionally, sedative drugs can affect an electroencephalogram (EEG) test. It is generally recommended to stop taking these medications for at least 72 hours before the test. For a child of this age, the purpose of an EEG is to rule out epilepsy. It is advised that the child undergo regular check-ups in the pediatric department for follow-up.
