Nitroglycerin 0.4 mg is a sublingual tablet used to relieve chest pain associated with angina, also known as angina pectoris [1]. It is a vasodilator, meaning it widens blood vessels, which helps to increase blood flow and oxygen supply to the heart muscle [1][2].
How quickly does nitroglycerin 0.4 mg work for chest pain?
Sublingual nitroglycerin 0.4 mg tablets typically dissolve under the tongue and begin to take effect within 1 to 3 minutes [1][3]. Relief from chest pain is usually experienced within 5 minutes [1].
When should I take another nitroglycerin 0.4 mg tablet?
If chest pain does not improve or worsens after one dose, a second dose can be taken 5 minutes later. If the pain persists, a third dose can be taken another 5 minutes later.
