What is GTN Spray (Glyceryl Trinitrate) used for?

GTN Spray (Glyceryl Trinitrate) is an inhalable medication used to treat patients who are suffering from angina or heart failure. The medication operates by quickly increasing blood flow to decrease discomfort and pain associated with these conditions. It is normally used as a short term treatment and is not recommended for long-term use. Your physician may also prescribe this medication for the treatment of other unlisted conditions.

How should I use GTN Spray (Glyceryl Trinitrate)?

GTN Spray (Glyceryl Trinitrate) should always be used according to your physician's instructions to get the best results from treatment. The normal dosage is one spray administered at the first sign of angina pain. Your physician may also prescribe it as a daily regimen based on your heart condition, but the spray is not meant to be used for long-term treatment. To use the medication gently shake the bottle to mix its contents, remove the cap, insert the applicator into the nostril, and inhale deeply while squeezing to draw the dosage into the nose. Always ask your physician any questions you have about using the medicine to ensure the correct administration.

What are the side effects of GTN Spray (Glyceryl Trinitrate)?

Some patients using GTN Spray (Glyceryl Trinitrate) have reported experiencing side effects such as:

  • Headaches
  • Fatigue or drowsiness
  • Dizziness
  • Flushing of the skin

Contact your physician immediately if any serious side effects appear such as a sudden drop in blood pressure when moving from a sitting to a standing position, changes in heart rate, faintness, or signs of an allergic reaction such as skin rashes, swelling, or difficulty breathing. These conditions may require reduced dosages, lower frequency of administration, or emergency medical attention in serious cases.

You are also suggested to inform your physician if you are malnourished or have recently had a heart attack, low oxygen volume in the blood, hypothermia, or severely decreased liver or kidney function as these conditions may cause unexpected complications during treatment.

Strictly follow all instructions provided to you by your physician or pharmacist while using GTN Spray (Glyceryl Trinitrate). Optimum and safe dosage can differ based on the patient and the condition being treated.

As this medication may be unsafe for certain patients, it is essential you always inform your physician if you are pregnant or breastfeeding, as well as if you have any allergies, other illnesses, or ongoing health conditions, and if you are taking any other form of medication, supplements, or herbal products.
