Nitroglycerin Spray Side Effects

Common Side Effects

For many medications, the prescribing information carefully explains the exact percentage of side effects that were seen in clinical trials. However, the prescribing information for almost all older medications, including many nitroglycerin products, includes only vague information on potential side effects, with no percentages provided. Therefore, it can be difficult to know exactly how often these adverse reactions occur.
In studies, the most common Nitrolingual side effects (occurring in at least 2 percent of people) included:
  • Headaches
  • Dizziness
  • Unusual sensations, such as burning or tingling.
Specific data for NitroMist side effects were not reported, although the possible reactions are probably similar to those of Nitrolingual because they are both nitroglycerin sprays that contain the same dosage.
With most nitroglycerin products, including nitroglycerin spray, the most notable side effect is headaches. These headaches can be quite severe and can happen every time a person uses nitroglycerin spray.
Other, less common reactions include:
  • Shortness of breath
  • Sore throat
  • Runny or stuffy nose
  • Flushing of the skin
  • General weakness
  • Abdominal (stomach) pain.

Final Thoughts

You may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have problems with a medicine that you have never tried.
Therefore, make sure to let your healthcare provider know if you develop any side effects while using nitroglycerin spray or if something "just does not seem right." While it may not be related to the medication, your healthcare provider will be able to diagnose and treat the problem.
