Diazepam Nasal Spray


Diazepam nasal spray is used for emergency situations to stop cluster seizures (episodes of increased seizure activity) in adults and children 6 years of age and older who are taking other medications to treat epilepsy (seizures).

Warnings & Precautions

Before using diazepam nasal spray:

  • tell your doctor and pharmacist if you are allergic to diazepam (Diastat, Valium), any other medications, or any of the ingredients in diazepam nasal spray. Ask your pharmacist for a list of the ingredients.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Be sure to mention any of the following: anticoagulants (blood thinners) such as warfarin (Coumadin, Jantoven); carbamazepine (Carbatrol, Epitol, Tegretol, others); cimetidine (Tagamet); clotrimazole (Lotrimin), cyclosporine (Gengraf, Neoral, Sandimmune); dexamethasone; imipramine (Tofranil); ketoconazole (Nizoral); medications for anxiety, mental illness, or nausea; omeprazole (Prilosec, Zegerid, in Yosprala); paclitaxel (Abraxane); phenobarbital; phenytoin (Dilantin, Phenytek); propranolol (Hemangeol, Inderal, Innopran); quinidine (in Nuedexta); rifampin (Rifadin, Rimactane, in Rifamate, in Rifater); sedatives; sleeping pills; terfenadine (not available in the US); theophylline (Elixophyllin, Theo-24, Theochron); tranquilizers; tranylcypromine (Parnate); troleandomycin (no longer available in the U.S.; TAO); and valproic acid (Depakote). Many other medications may also interact with diazepam nasal spray, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you have narrow-angle glaucoma (a serious eye condition that may cause loss of vision). Your doctor will probably tell you not to use diazepam nasal spray.
  • tell your doctor if you drink large amounts of alcohol or use or have used street drugs and if you have or have ever had lung problems such as asthma, chronic obstructive pulmonary disease (COPD), or pneumonia; depression or other mental illness; or liver or kidney disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while using diazepam nasal spray, call your doctor.
  • you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
  • you should know that your mental health may change in unexpected ways and you may become suicidal (thinking about harming or killing yourself or planning or trying to do so) while you are using diazepam nasal spray for the treatment of epilepsy. A small number of adults and children 5 years of age and older (about 1 in 500 people) who took anticonvulsants such as diazepam to treat various conditions during clinical studies became suicidal during their treatment. Some of these people developed suicidal thoughts and behavior as early as one week after they started taking the medication. There is a risk that you may experience changes in your mental health if you take an anticonvulsant medication such as diazepam, but there may also be a risk that you will experience changes in your mental health if your condition is not treated. You and your doctor will decide whether the risks of taking an anticonvulsant medication are greater than the risks of not taking the medication. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: panic attacks; agitation or restlessness; new or worsening irritability, anxiety, or depression; acting on dangerous impulses; difficulty falling or staying asleep; aggressive, angry, or violent behavior; mania (frenzied, abnormally excited mood); talking or thinking about wanting to hurt yourself or end your life; withdrawing from friends and family; preoccupation with death and dying; giving away prized possessions, or any other unusual changes in behavior or mood. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.

Dosage Of Diazepam Nasal Spray

  • Diazepam comes as a spray to inhale through the nose. It is used when needed, according to your doctor’s directions. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use diazepam nasal spray exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
  • Before diazepam nasal spray is prescribed, the doctor will talk to you and your caregiver about how to recognize signs of the type of seizure activity that should be treated with this medication. Your caregiver will also be taught how to administer the nasal spray.
  • Keep diazepam nasal spray with you or available at all times so that you will be able to use it to control your seizures when they occur.
  • If used regularly, diazepam may be habit-forming. Do not use a larger dose than your doctor tells you to. Diazepam nasal spray is not meant to be used on a daily basis. Diazepam nasal spray should not be used more than 5 times a month or more often than every 5 days. If you or your caregiver think that you need diazepam nasal spray more often than this, talk to your doctor.
  • Read all of the manufacturer’s instructions for using the nasal spray before you use your first dose.
  • Put the person having seizures on their side in a place where they cannot fall.
  • The person can be on their side or back to receive diazepam nasal spray.
  • Remove the device from the blister pack.
  • Hold the sprayer between your fingers and thumb, but be careful not to press the plunger.
  • Put the tip of the sprayer into one nostril until your fingers are against the bottom of the person’s nose.
  • Press the plunger firmly with your thumb.
  • Remove the tip from the nose.
  • The sprayer contains only one dose of medication. After you have used it, dispose of it safely, so that is out of the reach of children and pets.
  • Keep the person on their side. Take note of what time diazepam nasal spray was given, and continue to watch the person.
  • the seizures seem different or worse than usual.
  • you are worried about how often seizures are happening or how long seizures are lasting.
  • you are worried about a change in skin color or breathing of the person with seizures.
  • the person is having unusual or serious problems.


Keep all appointments with your doctor and the laboratory.

If you have symptoms that are different from your usual seizures, you or your caregiver should call your doctor immediately.

Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
