Nitroglycerin Patch Dosage

If your healthcare provider prescribes the nitroglycerin patch, dosing will mainly depend on how you respond to the medication. Regardless of the amount, you should wear one patch each day for 12 to 14 hours. It is essential that you give your body a 10- to 12-hour break from the drug to ensure the effectiveness of nitroglycerin.

An Introduction to Your Dosage of the Nitroglycerin Patch

The dose of nitroglycerin patches (Minitran™, Nitro-Dur®) your healthcare provider recommends will vary, depending largely on how you respond to the medication. As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
 

Nitroglycerin Patch Dosing for Angina

The standard starting dosage for nitroglycerin patches for the prevention of angina attacks (chest pain) is one 0.2 mg/hour, 0.3 mg/hour, or 0.4 mg/hour patch applied once a day and removed 12 to 14 hours later.
 
Do not forget to remove the patch at the directed time. As with all nitroglycerin products, it is important that your body gets a 10- to 12-hour break from the drug every day. Without this break, your body quickly becomes accustomed to the effects of nitroglycerin and the drug will become completely ineffective within 24 hours.
 

General Information on Using the Nitroglycerin Patch

Some considerations to keep in mind during treatment with the nitroglycerin patch include the following:
 
  • This patch is applied once a day and worn for 12 to 14 hours. Remember to give your body the 10- to 12-hour break as described.
 
  • Apply the patch to a clean, dry, hairless area of the body, preferably the chest. Do not apply it to the arms below the elbows or the legs below the knees. If a hairless area is not available, the hair can be clipped short but not shaved.
 
  • Choose an area that is free of irritations or cuts. It is best not to apply the patch right after bathing or showering, as the skin may not be completely dry.
 
  • Don't forget to remove the patch at the specified time, or the medication will quickly stop working for you.
 
  • You can swim, shower, or bathe while wearing the patch. In the unlikely event that the patch comes off, simply replace it with a new one, treating the patch as if it were the old one and removing it at your regular time.
 
  • For the medication to work properly, it must be used as prescribed.
 
  • If you are unsure about anything related to dosing with nitroglycerin patches, please talk to your healthcare provider or pharmacist.
