Nitroglycerin (Nitro-Dur) patch is a nitrate medication. It prevents angina (chest pain) by opening up your blood vessels to allow more blood to flow to the heart. Nitroglycerin (Nitro-Dur) comes as a transdermal patch that's applied directly on your skin once daily for 12 to 14 hours, then removed. Some common side effects of this medication include headache and low blood pressure. Avoid taking nitroglycerin (Nitro-Dur) patch with sildenafil (Viagra) or other similar medications because doing so can lead to dangerously low blood pressure.
Prevention of angina (chest pain)
Nitroglycerin (Nitro-Dur) patch is a nitrate that opens the blood vessels in your heart. This helps blood reach the heart better, which puts less stress on the heart and relieves heart-related chest pain.

Nitroglycerin (Nitro-Dur) patch is only for preventing chest pain; it doesn't treat chest pain that has already started. Your provider might also prescribe nitroglycerin (Nitrostat) sublingual tablet) or Nitrolingual (nitroglycerin lingual spray) for treating chest pain. If you have to take either of these for active chest pain, make sure to sit down first to avoid side effects like sudden low blood pressure and dizziness.
Nitroglycerin (Nitro-Dur) patch can cause headaches as a side effect. To prevent headaches, get up slowly from a sitting or lying position. Also, avoid drinking alcohol. If the headaches are too bothersome for you, ask your provider if it's safe for you to take a pain medication, such as acetaminophen (Tylenol).
Nitroglycerin (Nitro-Dur) patch can lower your blood pressure, which can lead to dizziness, lightheadedness, or fainting. Avoid alcohol because it can worsen dizziness and lower your blood pressure more.

When taken together, your blood pressure can become dangerously low.
Tips for how to use nitroglycerin (Nitro-Dur) patch:
Wash your hands before and after applying a new nitroglycerin (Nitro-Dur) patch. This helps avoid spreading medication to other people or places.
Apply nitroglycerin (Nitro-Dur) patch to clean, dry, hairless skin. Avoid applying nitroglycerin (Nitro-Dur) patch below the knee, below the elbow, or on skin that has folds, scar tissue, injuries, or irritation.
Apply nitroglycerin (Nitro-Dur) patch to a different area of the body every day to help prevent skin irritation. Fold back the remaining side of the patch to remove the backing. Then wash your hands.
You can shower or bathe with nitroglycerin (Nitro-Dur) patch on.
To remove nitroglycerin (Nitro-Dur) patch, press down on the center of the patch to raise the edges and slowly peel away from your skin. Then, wash the skin area with soap and water and dry with a towel. Then wash your hands.

Risk factors: Older adults | Not enough fluids in the body | Taking other medications that can lower blood pressure
Nitroglycerin (Nitro-Dur) patch can cause dangerously low blood pressure in some people, especially when you're getting up from a sitting or lying position. This can lead to dizziness, fatigue, and lightheadedness. The risk is higher for older adults and for people starting nitroglycerin (Nitro-Dur) patch for the first time. Change positions slowly until your body is used to this medication to avoid falling and hurting yourself. Get emergency help if you feel like like you are going to pass out and are experiencing an irregular heart beat, nausea, vomiting, weakness, changes in vision, cold and clammy skin, or if your chest pain gets worse.
Don't take nitroglycerin (Nitro-Dur) patch with phosphodiesterase inhibitors, such as sildenafil (Viagra). Doing so can lead to dangerously low blood pressure.
Risk factors: Hypertrophic cardiomyopathy
Although rare, taking nitroglycerin (Nitro-Dur) patch can worsen chest pain that's caused by a heart problem called hypertrophic cardiomyopathy. This is a condition where your heart muscles are too thick and can't pump blood as well. If you’ve been diagnosed with hypertrophic cardiomyopathy, check with your provider to make sure that nitroglycerin (Nitro-Dur) patch is right for you. If you take nitroglycerin (Nitro-Dur) patch and it worsens your chest pain, get emergency help right away.
Risk factors: Using nitroglycerin (Nitro-Dur) patch continuously over a longer period of time
Your body can get used to nitroglycerin (Nitro-Dur) patch over time. When this happens, the same amount of medication might no longer work as well as it used to prevent chest pain. This is called tolerance or tachyphylaxis. Your provider will likely tell you to avoid taking nitrates (e.g., isosorbide mononitrate (Monoket) or isosorbide dinitrate (Isordil)) for a certain amount of time every day to give your body a 'break' from it. Let your provider know if you experience problems with chest pain or exercise abilities during the times you are not wearing your nitroglycerin (Nitro-Dur) patch patch.
Risk factors: First starting nitroglycerin (Nitro-Dur) patch | Higher doses of nitroglycerin (Nitro-Dur) patch | Drinking alcohol
Some people experience daily headaches after starting nitroglycerin (Nitro-Dur) patch. Sometimes, these headaches happen as you go from a sitting or lying position to a standing position. The headaches often ease or go away after you've used nitroglycerin (Nitro-Dur) patch a few times and your body gets used to the medication. If the headaches are bothersome, talk to your healthcare provider about other options.
Adults: The typical starting dose is 1 patch (ranging from 0.2 mg/hr to 0.4 mg/hr) applied to the skin once daily for 12 to 14 hours, then taken off for 10 to 12 hours.
