Understanding tonic-clonic epilepsy
"Epilepsy, Tonic-Clonic" is the NLM's MeSH heading for what most people still call grand mal epilepsy. NLM defines it as "A generalized seizure disorder characterized by recurrent major motor seizures. The initial brief tonic phase is marked by trunk flexion followed by diffuse extension of the trunk and extremities," and its entry terms include "Grand Mal Seizure Disorder." So this category is about one seizure type — whole-body stiffening followed by rhythmic jerking, with consciousness lost — not focal or absence seizures. StatPearls (NCBI Bookshelf) describes the same sequence clinically: a tonic phase that "can start with a scream with a generalized stiffening of the body with or without cyanosis," after which "clinical features evolve into clonic jerking followed by postictal sleepiness, confusion, or agitation." StatPearls calls that postictal state — confusion, somnolence, headache, mood change — "common and characteristic," so the grogginess afterward is part of the expected picture rather than a new symptom. The number that changes what a bystander does is five minutes. MedlinePlus (NLM) states that "it is a medical emergency if seizures last longer than 5 minutes or if a person has many seizures and does not wake up between them," and StatPearls sets the same threshold: "Seizures lasting more than 5 minutes or recurrent seizures without return to baseline consciousness meets the definition of status epilepticus." Note the second half of both sentences — failing to come round between seizures counts, even when no single seizure runs long. What people get wrong: MedlinePlus instructs "Do not place anything between the person's teeth during a seizure (including your fingers)" and "Do not restrain (try to hold down) the person." This is general information, not medical advice.
First-line treatment
Acute care is governed by the American Epilepsy Society's 2016 evidence-based guideline on convulsive status epilepticus, which states that "A benzodiazepine (specifically IM midazolam, IV lorazepam, or IV diazepam) is recommended as the initial therapy of choice," given as "an adequate single full dose rather than broken into multiple smaller doses"; for the second-therapy phase it lists fosphenytoin, valproic acid and levetiracetam, and says "there is no clear evidence that any one of these options is better than the others." For ongoing daily therapy, the 2018 AAN/AES practice guideline update on new-onset epilepsy makes a point worth knowing before a drug is chosen: "Data are lacking on efficacy in new-onset generalized tonic-clonic seizures, juvenile myoclonic epilepsy, or juvenile absence epilepsy." Its firmest recommendation — lamotrigine at Level B — is for new-onset focal epilepsy, not for the tonic-clonic presentation this page is about. Drug choice is individual; no doses here.
