Nitroglycerin Patch Side Effects

Common Reactions

The nitroglycerin patch has been studied extensively in clinical trials. In these studies, one group of people received nitroglycerin patches, while another group was given a placebo (a patch that does not contain any active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the placebo.
In clinical trials, the most problems with nitroglycerin patches included:
  • Headaches -- in up to 63 percent of people
  • Lightheadedness -- up to 6 percent
  • Low blood pressure (hypotension) or fainting -- up to 4 percent.
With most nitroglycerin products, including nitroglycerin patches, the most notable side effect is headaches. These headaches can be quite severe and can occur every time a person uses the patch. Headaches are most commonly seen with a higher nitroglycerin patch dosage. Do not adjust your dosage or skip doses to avoid headaches, however, without first talking to your healthcare provider.

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 patches 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.
