common side effect and what are you watching for nitroglycerin
Nitroglycerin is a medication commonly used to treat angina (chest pain) by widening blood vessels to improve blood flow to the heart. However, it also comes with several potential side effects that patients should be aware of.
Common side effects of nitroglycerin include headaches, which can occur in a significant number of users—up to 64%. Other frequent side effects include dizziness, lightheadedness, weakness, fast heart rate, nausea, vomiting, and flushing (reddening and warming of the skin) (Healthline). Additionally, allergic reactions may manifest as skin rash, itching, hives, or swelling of the face, lips, tongue, or throat (Cleveland Clinic).
More serious side effects that require immediate medical attention include breathing problems, wheezing, racing heart, blurred vision, and unusual weakness or fatigue. If any of these symptoms develop, it is essential to consult a doctor right away (WebMD, MedlinePlus).
In summary, when using nitroglycerin, patients should closely monitor for symptoms such as headaches, dizziness, rash, and any signs of allergic reactions, alongside serious side effects like difficulty breathing or changes in vision. Proper awareness and prompt reporting of these side effects can help ensure safe use of the medication.
