Home rescue medications — what they are and when vets prescribe them

Some pets with epilepsy are prescribed medication to be given at home during prolonged or cluster seizures. Here is what these medications are, how they work, and what to expect.

This guide does not instruct you to administer rescue medication. Rescue medications must be prescribed by your veterinarian with specific instructions for your individual pet. Never administer any medication during a seizure unless it has been specifically prescribed for that purpose.

What are home rescue medications?

Home rescue medications — sometimes called acute seizure medications or emergency anti-seizure medications — are drugs prescribed by veterinarians for owners to administer at home when a seizure meets certain criteria. They are designed to stop a prolonged seizure or interrupt a cluster seizure before it escalates to a veterinary emergency.

Not every pet with epilepsy will be prescribed a rescue medication. They are typically considered for pets with a history of cluster seizures, prolonged seizures, or status epilepticus — where the risk of a dangerous seizure event is established and the time needed to reach an emergency clinic could be critical.

Diazepam (rectal)

Rectal diazepam was historically the most commonly used home rescue medication in dogs. It is a benzodiazepine that acts quickly to suppress seizure activity. It is administered via the rectum — absorbed through the rectal mucosa into the bloodstream — which allows it to be given during an active seizure without placing hands near the pet's mouth. Your veterinarian will provide specific instructions on dose and the circumstances under which it should be used.

Midazolam (intranasal or buccal)

Midazolam — another benzodiazepine — can be administered intranasally (into the nostril) or into the buccal space (between the cheek and gum). Research suggests that intranasal midazolam is rapidly absorbed and may be as effective as intravenous diazepam for stopping seizures. It is increasingly used as a home rescue option because it is easier and safer to administer than rectal diazepam, and well tolerated by most pets.

When is rescue medication typically indicated?

Your veterinarian will establish specific criteria for your pet based on their seizure history. Common thresholds discussed in veterinary guidelines include:

  • A seizure lasting longer than a specified duration (often 3–5 minutes)
  • A second seizure occurring within a defined time window after the first
  • Failure to regain normal consciousness between seizures

These thresholds are individualized. Ask your vet specifically: "Under what circumstances should I give the rescue medication, and when should I still go directly to the emergency vet?"

Rescue medication does not replace emergency vet care in all situations

Home rescue medication is a first-line intervention — not a replacement for emergency veterinary care in all cluster or prolonged seizure situations. It is designed to provide rapid treatment while transport to a veterinary clinic is arranged, or to interrupt seizures that would otherwise escalate. Your vet will advise specifically on when to give the medication, when to proceed to the emergency clinic after giving it, and when to go directly to emergency care without using rescue medication first.

Talk to your vet before an emergency happens

If your pet has a history of cluster seizures or prolonged seizures and has not been prescribed a rescue medication, ask your veterinarian whether one would be appropriate. Having a plan — and medication on hand — before an emergency occurs significantly improves outcomes and reduces owner anxiety.

What to ask your vet about rescue medication
  • Is a rescue medication appropriate for my pet given their seizure history?
  • Which medication and route of administration do you recommend?
  • Under exactly what circumstances should I give it?
  • What do I do if the rescue medication doesn't stop the seizure?
  • When should I go directly to the emergency clinic instead?
  • How should I store it and how do I know when it has expired?
Key takeaways
  • Home rescue medications are prescribed for pets with cluster or prolonged seizure history to use during seizure emergencies
  • Rectal diazepam and intranasal or buccal midazolam are the most common options
  • Never administer any medication during a seizure without explicit veterinary prescription and instruction
  • Your vet will give specific criteria for when to use the medication — and when to go directly to emergency care
  • Home rescue medication is a first-line tool, not a replacement for emergency vet care in all situations
  • If your pet has cluster seizure history and no rescue medication, ask your vet whether one is appropriate
