Nitrolingual Overdose

The complications that may occur with a Nitrolingual overdose can include vision problems, nausea and vomiting, severe headache, and even coma and death. Because this situation is so serious, prompt medical attention should be obtained for anyone who takes too much. Treatment will involve relieving the symptoms -- in particular, low blood pressure.

Is It Possible to Take Too Much Nitrolingual?

Nitrolingual® Pumpspray (nitroglycerin spray) is a prescription spray approved for the treatment of chest pain (angina) due to coronary artery disease. As with most medications, it is possible to use too much Nitrolingual. In fact, an overdose can be dangerous.

Effects of an Overdose With Nitrolingual

Known effects of an overdose with any nitroglycerin product, including Nitrolingual, include:
  • Feelings of a rapidly or forcefully beating heart (heart palpitations)
  • Vision problems
  • Nausea and vomiting
  • Sweating
  • Severe, throbbing headache
  • Confusion
  • Fever
  • Dizziness, lightheadedness, or fainting (signs of very low blood pressure)
  • A spinning sensation (vertigo)
  • Shortness of breath
  • Slow heart rate
  • Blue skin, a sign of methemoglobinemia (a condition in which blood cannot adequately deliver oxygen to the body's tissues)
  • Paralysis
  • Coma
  • Seizures
  • Death.

Treating an Overdose

Treatment for a Nitrolingual overdose, if necessary, will involve supportive care, which consists of treating the symptoms that occur as a result of the overdose. Of greatest importance, usually, is an effort to increase blood pressure. To do this, intravenous fluids can be useful, but also can be dangerous in certain individuals with kidney failure or congestive heart failure.
For the treatment of methemoglobinemia, the first choice is usually methylene blue, given intravenously (by IV).
It is important that you seek prompt medical attention if you believe that you or someone else may have overdosed on Nitrolingual.
