Nitroglycerin Ointment


Nitroglycerin Ointment

Generic Name: Nitroglycerin (NYE-troe-GLIS-er-in)Brand Name: Nitro-Bid

Nitroglycerin Ointment is used for:

Preventing chronic chest pain caused by heart disease. It also may be used for other conditions as determined by your doctor.

Nitroglycerin Ointment is a nitrate. It works by relaxing (widening) blood vessels. Chest pain occurs when the heart needs more oxygen than it can get. Relaxing blood vessels allows blood to flow more easily. This reduces the heart's workload and the amount of oxygen needed by the heart.

  • you are allergic to any ingredient in Nitroglycerin Ointment
  • you have increased pressure in or severe injury to the head
  • you have severe anemia
  • you are taking a phosphodiesterase type 5 inhibitor (eg, sildenafil)

Contact your doctor or health care provider right away if any of these apply to you.
