Nitroglycerin

When and How to Use Nitroglycerin

Some general considerations to keep in mind during treatment with nitroglycerin include the following:
 
  • This medicine comes in several different forms. Refer to your healthcare provider's specific directions for your particular product and situation.
 
  • The long-acting forms (patches, ointment, and capsules) are used to prevent chest pain and are used on a daily basis. The short-acting forms (tablets and spray) are used as needed to relieve chest pain.

 

  • As you might imagine, the instructions for using nitroglycerin anal ointment (for anal fissures) are quite different from the instructions for other nitroglycerin products (see Rectiv Dosage for more information)
 
  • For the short-acting forms (tablet or spray), you can use up to three doses within 15 minutes. If chest pain continues after a third dose, you should seek immediate medical attention, as you may be having a heart attack.
 
  • For nitroglycerin ointment or patches, carefully read the directions included with your particular product. If you have any questions, talk to your healthcare provider or pharmacist.
 
  • For the medication to work properly, it must be used as prescribed.
