Nitrogesic Ointment (Nitroglycerin 0.2%)
How it works
Nitrogesic—for the treatment of moderate to severe pain associated with chronic anal fissure
Nitrogesic, a nitroglycerin ointment, is the only FDA-approved medicine for the treatment of moderate to severe pain from chronic anal fissure. In a clinical study, Nitrogesic was found to be effective in treating moderate to severe pain from chronic anal fissure. One common side effect of Nitrogesic is headache. Here’s why: the nitroglycerin in Nitrogesic increases blood flow to the anal area. That same kind of increased blood flow also occurs in the head and brain, which can cause headaches.
Nitrogesic may cause dose-related headaches, which may be severe, but as you get used to Nitrogesic, they may become less severe. The good news is that this type of headache usually doesn’t last very long and can be treated with an over-the-counter medicine, such as Tylenol® (acetaminophen). If the headaches are unpleasant, you may need to ask your doctor whether you should stop using Nitrogesic. There are additional side effects and risks associated with Nitrogesic. Please see Important Risk Information below.
How to use Nitrogesic
- Apply the ointment every 12 hours exactly as your doctor has told you to
- Cover your finger with plastic wrap, a disposable surgical glove, or a finger cot
- Lay the covered finger alongside the 1-inch dosing line marked on the side of the medicine box so that the tip of your finger is at one end of the dosing line
- Refer to carton for accurate dosage guide
- Starting at the tip of the finger, squeeze the ointment onto your finger so it is the same length as what is marked on the box
