Final answer:
Nitroglycerin, a medication used for high blood pressure and angina, often causes side effects like headache, dizziness, warmth, and increased heart rate. The most common side effect is headache due to increased blood flow from blood vessel dilation.
Step-by-step explanation:
Nitroglycerin is a medication often used in the treatment of high blood pressure and angina. Common side effects of Nitroglycerin include headache, dizziness, lightheadedness, skin flushing or warmth, and increased heart rate, among others. Headache is considered the most common side effect and is generally considered normal when taking Nitroglycerin.
It happens because Nitroglycerin causes the blood vessels to dilate (expand), which enhances the blood flow. This increased blood flow may contribute to the development of headaches. Other aspects, such as patient tolerance to the medication, the dose of Nitroglycerin, and frequency of use, will also contribute to the prevalence and intensity of this side effect.
