Intranasal Lorazepam for Prolonged Seizures

If prolonged tonic-clonic seizures or clusters of shorter seizures are not treated, they can sometimes lead to status epilepticus. Status epilepticus is a prolonged seizure that lasts for 30 minutes or longer. Quick treatment within 3-5 minutes can stop a prolonged seizure or status epilepticus. You might be able to avoid going to an emergency room with early treatment.

Lorazepam for Seizures A caregiver will use an atomizer to put the medicine in your nose as a spray or mist. This way, it goes straight into your bloodstream and there is no need to swallow.

Using Lorazepam Instead of Valium Research suggests giving lorazepam in the nose instead of rectal Valium for patients who do not have an IV. We have found that it:

  • Is safe.

  • Works quickly.

  • Sends medicine right to the blood and spinal fluid.

  • Is less likely to build up when given more than once.

  • Works as well as IV medicines to stop seizures.

Side Effects

  • Fatigue

  • Irritation in the lining of your nose

If Seizure Doesn’t Stop

Follow the directions your doctor gave you.

Repeat Seizures

Follow the directions your doctor gave you. For some people, your doctor may instruct you to repeat the lorazepam for repeat seizures.
