Why should you avoid handling nitroglycerin pills with bare hands?

Answer 1

Many people are surprised to learn that the nitroglycerin in the tablets is the same chemical compound as the nitroglycerin that is used as an explosive. The chemical compound is very volatile, which means that it is difficult to contain in tablet form. By handling the tablets, the nitroglycerin may be absorbed through the skin from the tablet. Briefly touching the tablets should not be a concern, but they should not be handled excessively. Also, make sure nitroglycerin tablets are stored in a cool, dry place - not the car or the bathroom cabinet. Discard the bottle 6 months after it is first opened, as the tablets may lose their effectiveness.
