As with any medicine, side effects are possible with Nitrolingual® Pumpspray (nitroglycerin spray). However, not everyone who takes the medication will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Nitrolingual. Your healthcare provider can discuss a more complete list with you.)
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 side effect information, with no percentages provided. Therefore, it can be difficult to know exactly how frequently these problems occur.
In studies, the most common Nitrolingual side effects (occurring in at least 2 percent of people; exact percentages not reported) included:
- Headache
- Dizziness
- Unusual sensations, such as burning or tingling.
With most nitroglycerin products (including Nitrolingual), the most notable side effect is headaches. These headaches can be quite severe and can happen every time a person uses Nitrolingual.
Other, less common reactions included:
- Shortness of breath
- Sore throat
- Runny or stuffy nose
- Flushing of the skin
- General weakness
- Stomach pain (abdominal pain).
