Call emergency services when a seizure lasts five minutes, repeats without recovery, affects breathing, causes serious injury, or occurs in water, during pregnancy, or in someone with diabetes. Even when the person recovers quickly, a first suspected seizure needs prompt medical assessment, and recurring or changing episodes need a planned review rather than indefinite observation.
Key takeaways
- Call emergency services for a seizure lasting five minutes or longer.
- Call for repeated seizures without recovery between them.
- Arrange medical assessment after a first suspected seizure.
- Record the seizure duration, movements, breathing, and recovery.
When a Seizure Needs an Ambulance
Call emergency services for a seizure lasting five minutes or longer. Do the same for repeated seizures without recovery between them: this is status epilepticus, and waiting for the person to “come around” can delay lifesaving treatment.
| Situation | Action | Why it is urgent |
|---|---|---|
| Convulsive seizure lasting five minutes or repeated seizures without recovery | Call emergency services | Prolonged or recurrent seizures can become status epilepticus |
| Breathing difficulty during seizure, absent breathing, or failure to return to usual alertness | Call emergency services | The person may need airway support or urgent brain assessment |
| Serious injury, seizure in water, pregnancy, diabetes, or a first-ever suspected seizure | Call emergency services | The seizure or its underlying trigger can be dangerous even if it stops |
| Seizure after head trauma, or with fever, a new severe headache, weakness, or speech difficulty | Call emergency services | These signs can indicate bleeding, infection, stroke, or another acute brain disorder |
Seek urgent medical advice rather than waiting for a routine appointment when the person has:
- Persistent confusion or does not return to their usual alertness
- New one-sided weakness, trouble speaking, or neck stiffness
- A marked change in the usual seizure pattern
- Seizures after missed medication, vomiting, or a medication change
Do not stop an antiseizure medicine or change its dose without the prescriber. Sudden withdrawal can trigger prolonged or repeated seizures; report missed doses, vomiting, drug interactions, and difficult side effects promptly.
What to Do After a First Suspected Seizure
A first-ever seizure needs prompt medical assessment even if the person feels normal afterward. One unexplained episode does not establish epilepsy: fainting, heart-rhythm problems, migraine, low blood sugar, sleep disorders, medication effects, and psychogenic nonepileptic seizures can look similar.
A clinician can review the event, examine the nervous system, and check triggers such as glucose, electrolytes, infection, head injury, or drug exposure. Ask a witness to describe what happened and provide a video if one exists.
| Situation | What to do | Why it matters |
|---|---|---|
| Fully recovered after a first suspected seizure | Arrange prompt medical assessment | The cause remains uncertain, and a reversible trigger needs checking |
| Persistent confusion after seizure or failure to return to usual alertness | Seek urgent medical review | Ongoing seizure activity, injury, or another brain problem needs assessment |
| Weakness on one side after seizure or new speech difficulty | Seek emergency assessment | These signs can indicate stroke or another acute brain disorder |
| New severe headache, fever, neck stiffness, or seizure after head trauma | Seek urgent medical review | Infection, bleeding, or swelling may require immediate treatment |
| A marked change from the person’s usual seizure pattern | Contact urgent medical services | A new pattern may reflect an acute illness rather than established epilepsy |
Do not wait for another episode before arranging assessment. Do not stop or change an antiseizure medicine without the prescriber; missed doses, vomiting, side effects, and drug interactions need prompt advice.
When a Routine Epilepsy Appointment Is Appropriate
Arrange a prompt outpatient consultation when episodes recur, change, or are easy to miss but occur without emergency warning signs. Recurrent unprovoked seizures need assessment because epilepsy is diagnosed by the pattern of events, not by one symptom alone.
| Situation | Prompt outpatient appointment | Seek urgent medical advice instead |
|---|---|---|
| Recurrent unprovoked seizures | Book a review to confirm the diagnosis, review triggers, and discuss treatment. | Do not wait if confusion persists, weakness or speech difficulty appears, or recovery does not return to normal. |
| Breakthrough seizure | Arrange a medication review, especially after missed doses, a new medicine, vomiting, sleep loss, or alcohol exposure. | Seek urgent help if seizures repeat without recovery, last five minutes, or cause serious injury. |
| New seizure pattern | Report different movements, a longer episode, a new warning sensation, or a change in recovery. | Obtain urgent assessment for a new severe headache, fever, head injury, or sudden neurological deficit. |
| Brief impaired awareness | Record staring, pauses, lip-smacking, lost conversation, and the person’s response afterward; arrange evaluation if episodes recur. | Seek urgent advice if confusion remains or the event occurs with collapse, injury, or breathing difficulty. |
Bring the medication list, missed-dose history, seizure diary, and witness description or video. Ask whether an epilepsy-protocol MRI, electroencephalogram, or specialist referral is appropriate when the diagnosis remains uncertain, seizures continue despite treatment, or side effects make medication difficult to tolerate.
How to Help During a Seizure and Record What Happened
During a seizure, start a timer and give seizure first aid: stay with the person, move furniture and sharp objects away, loosen tight clothing, and protect the head with a folded coat or cushion. Do not restrain them, put anything in their mouth, or give food, water, or medicine until they are fully alert.
- Keep watching their breathing and movements. Note whether the eyes or head turn to one side, whether one limb jerks first, and whether they become stiff before rhythmic shaking.
- Place the person on their side after convulsions stop, especially if they are drowsy or vomiting. Check that they are breathing normally.
- Record the duration, injuries, loss of bladder control, tongue biting, skin colour, and how long confusion or sleepiness lasts.
- Call emergency services if the seizure lasts five minutes, repeats without recovery, causes breathing trouble or serious injury, occurs in water, or affects someone who is pregnant, has diabetes, or has never had a seizure.
A seizure diary and video can help distinguish epilepsy from fainting, migraine, sleep disorders, medication effects, or psychogenic nonepileptic seizures. Film only if it is safe; never delay first aid to record.
| What you record | Why it matters | Action |
|---|---|---|
| Before and during the event | Triggers, missed doses, illness, posture, warning symptoms, movements, and awareness help classify it | Arrange prompt assessment after a first suspected seizure |
| After the event | Persistent confusion, weakness, speech trouble, fever, severe headache, or failure to return to normal raises concern for an acute brain problem | Seek urgent medical advice |
When Testing or Specialist Referral Should Escalate
A normal routine EEG does not rule out epilepsy. If the diagnosis remains uncertain, ask about a sleep-deprived EEG, ambulatory EEG, or video-EEG; video-EEG can compare an episode with recorded brain activity and identify mimics such as fainting or psychogenic nonepileptic seizures.
An epilepsy-protocol MRI is important when focal epilepsy is suspected or routine imaging shows nothing, because standard scans can miss small structural abnormalities.
Refer to an epilepsy specialist when:
- The diagnosis remains unclear after the initial assessment, examination, and review of glucose, electrolytes, medicines, alcohol, and recreational drugs.
- Seizures continue despite treatment, or medication side effects prevent an adequate dose.
- The seizure type is complex, the episodes are changing, or the treatment plan is difficult to interpret.
Drug-resistant epilepsy means ongoing seizures after two appropriately chosen, adequately dosed, tolerated, and correctly used antiseizure medicines. That point calls for a comprehensive epilepsy-centre assessment, not indefinite medication changes alone. The team may combine epilepsy-protocol MRI, video-EEG, neuropsychological testing, and functional or metabolic studies to locate a treatable seizure-producing region.
Ask about neurosurgical evaluation when seizures are focal and remain uncontrolled. Dr. Deepak Bariya can help assess whether a structural brain or spine-related finding needs specialist surgical review, while an epilepsy centre decides whether resection, disconnection, neuromodulation, or dietary treatment is suitable.
