Cluster Seizures: Treatment Options & Emergency Care

Cluster seizures (in epilepsy context) refer to seizure clusters—multiple events in hours/days. Note: “Cluster headache” is a distinct primary headache disorder; this article addresses seizure clusters.

Acute Treatment

1. Rescue benzodiazepines: Intranasal midazolam (Nayzilam), rectal diazepam (Diastat), buccal lorazepam — first-line, fast absorption.
2. Second-line (if rescue fails): IV benzodiazepines (lorazepam, midazolam) in ER; loading dose of IV ASM (levetiracetam, valproate, lacosamide, phenytoin/fosphenytoin).
3. Supportive: Oxygen, IV fluids, cardiac monitoring, airway protection.
4. Pain/comfort: Post-ictal headache → NSAIDs/acetaminophen; positioning, reassurance.

Preventive Strategies

• Optimize maintenance ASMs.
• Add clobazam (intermittent or daily), perampanel, or other adjuncts.
• Identify/avoid triggers: sleep, stress, alcohol, missed doses.
• Consider neuromodulation (VNS, RNS, DBS) for refractory cases.

When to Hospitalize

• Rescue failure.
• Status epilepticus (>5 min continuous or recurrent without recovery).
• Injury, aspiration risk, or medical instability.

A personalized seizure action plan—shared with family, school, caregivers—is essential.
