NitroMist Dosage

When relieving chest pain with NitroMist, you can use up to three sprays within 15 minutes after chest pain (angina) has begun. If your pain is not relieved after the third spray, seek immediate medical attention. You can also use NitroMist immediately prior to an activity that is likely to cause angina. However, do not use this drug more often or at higher doses than necessary.

An Introduction to Dosing With NitroMist

There is only one standard dose for NitroMist® (nitroglycerin spray). As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

NitroMist Dosage for Angina

At the start of an angina (chest pain) attack, use one or two sprays of NitroMist on or under the tongue. If necessary, a second spray (or third if two sprays were used initially) may be used after five minutes. Use no more than three sprays within 15 minutes.
If you use a third spray and your chest pain continues, it is time to seek immediate medical attention. You may be having a heart attack or other serious heart problem.
Do not use NitroMist more frequently or at a higher dose than absolutely necessary. Using it too often can result in a tolerance to the drug, which means your body becomes accustomed to it and no longer responds to the medication.

General Information on Using NitroMist

Some considerations to keep in mind during treatment with NitroMist include the following:
  • This medication comes in the form of a liquid that is sprayed on or under the tongue.
  • You can use up to three sprays within 15 minutes. If your chest pain is not adequately relieved after one spray, try another. If chest pain continues after a third spray, seek immediate medical attention.
  • NitroMist can also be used 5 to 10 minutes before activity that is anticipated to cause chest pain.
  • Do not shake the bottle. The first time you use each bottle, you must prime it by spraying it 10 times into the air. Thereafter, you will need to reprime it before use (if you haven't used it in the past six weeks) by spraying it twice into the air.
  • Do not rinse or spit for 5 to 10 minutes after receiving a NitroMist dosage.
  • For NitroMist to work properly, it must be used as prescribed.
  • If you are unsure about anything related to dosing with NitroMist, please talk to your healthcare provider or pharmacist.
