What is Nayzilam?
Nayzilam (midazolam) is a benzodiazepine.
Nayzilam nasal spray is a prescription medicine used short term to treat seizure clusters (also called "acute repetitive seizures") in adults and children at least 12 years old.
Nayzilam is a federal controlled substance (C-IV) because it can be abused or lead to dependence. Keep in a safe place to prevent misuse and abuse. Selling or giving away this medicine may harm others and is against the law. Tell your healthcare provider if you have abused or been dependent on alcohol, prescription drugs, or street drugs.
It is not known if Nayzilam is safe and effective in children under 12 years of age.
You should not use Nayzilam if you have narrow-angle glaucoma.
Nayzilam can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing. A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, if you are hard to wake up, or if you stop breathing.
Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
