MedDataToolNitroglycerin is a medication used to quickly relieve chest pain from angina, which is caused by reduced blood flow to the heart. It works by relaxing and widening blood vessels, making it easier for blood to flow and reducing the heart's workload. You take it as a tablet that you place under your tongue at the first sign of chest pain, starting with one tablet and allowing it to dissolve; you can take another every 5 minutes if needed, but no more than three tablets in 15 minutes. It's important to know that you should not use nitroglycerin if you are taking certain medications for erectile dysfunction, like sildenafil, as this can cause a dangerous drop in blood pressure. Always talk to your doctor about any medications you are taking to avoid serious interactions.
