The most common side effect experienced by patients taking Nitroglycerin for angina relief is a headache. Nitroglycerin works by dilating blood vessels, which can lead to an increase in blood flow to the brain. This vasodilation can cause increased intracranial pressure, resulting in headaches. It's important for patients to be aware that, while bothersome, headaches are typically a sign that the medication is having its intended effect of relaxing blood vessels and alleviating angina symptoms.

Understanding this side effect is crucial for healthcare providers when counseling patients about the potential reactions to Nitroglycerin. While other side effects may occur, headaches are particularly common and can help inform decisions regarding the management of angina and related symptoms.
