What is Nighttime NTG and Why is it Used?

Nighttime NTG refers to the use of nitroglycerin during evening or nighttime hours, primarily to manage conditions like angina (chest pain) or hypertension. Nitroglycerin works by relaxing blood vessels, improving blood flow, and reducing the workload on the heart. It’s often prescribed for individuals who experience symptoms at night or early morning.
💡 Note: Always consult your healthcare provider before starting or adjusting your NTG regimen.

Using nighttime NTG correctly is crucial for its effectiveness and your safety. Here’s a step-by-step guide:

- Monitor Side Effects: Common side effects include headaches, dizziness, or flushing. Report severe symptoms immediately.
