Triamcinolone (Nasal)

Triamcinolone, administered via nasal spray, is also known by the brand names Nasacort and Tri-Nasal and is prescribed by doctors to treat seasonal hay fever allergy symptoms such as runny or itchy nose, sneezing and other symptoms.


What is Triamcinolone?

Triamcinolone is a nasal spray that doctors may prescribe to patients with seasonal hay fever and allergies. Triamcinolone is a cortisone-like steroid medication that works to reduce the inflammation that occurs when a patient is suffering from allergies. This inflammation is known as rhinitis and has the following symptoms;

  • Runny nose
  • Stuffy nose
  • Itchy nose

Though their symptoms may have commonalities, it is not recommended that Triamcinolone be used to treat symptoms of the common cold. It may take a few days to experience the full effect of Triamcinolone on seasonal allergies, so it is advised that regular sufferers of hay fever and seasonal allergies begin their treatment regimen two to three weeks before the start of hay fever season.

Typically, patients are instructed to spray each nostril once per day, but doses vary according to patient health, age, weight, time of year and response to this and other corticosteroids in their medical history. Adults should help children administer their doses of Triamcinolone to make sure they are getting the correct dosage.

Triamcinolone nasal spray does not cure allergies or hay fever, it controls the symptoms. If you have not experienced improvement in your symptoms after three weeks of use, you should contact your doctor to adjust the dose or make other changes to your medications. Keep track of the amount of sprays you have used from your prescription's bottle, as after 120 sprays, the remaining liquid in the bottle does not contain the correct amount of medication any longer.

How does it work?

Triamcinolone, when administered by nasal spray, works to block the release of natural substances that cause allergy symptoms, reducing the swelling that these substances cause. Triamcinolone belongs to a family of medications called corticosteroids, which are a classification of steroid hormones.

Corticosteroids such as Triamcinolone work by copying what hormones in the body produce naturally in the adrenal glands but in levels that exceed normal cell production. When the body has higher levels of these hormones, inflammatory conditions that occur because of allergies and other irritants can be reduced.

What is hay fever?

Hay fever, also known under the name of allergic rhinitis, is nasal passage inflammation that occurs by an overactive immune system responding to allergen particles found floating in the air. People who suffer from hay fever have a variety of symptoms that include stuffy nose, runny nose, sneezing, watery eyes that are red and itchy as well as puffy and swollen at times. These symptoms are annoying and persistent enough to affect sleep patterns, concentration and the ability to go to school or work.

Hay fever is typically environmentally related and triggered by substances such as pet hair, pollen, pet dander, airborne mold spores, dust and other irritants. Tree pollen, grasses and weeds are all culprits of creating environmental allergens. Allergy testing by your doctor will help determine the specific allergens that affect you so that the best treatment is prescribed for your symptoms. There is evidence that allergies may be hereditary but, at the same time, environmental studies suggest that exposure to pet dander and other triggers at an early age may lessen risks associated with developing allergies later. The name hay fever came about because of an early, erroneous assumption that symptoms of allergic rhinitis were brought on by smelling new hay. Today, science tells us that it is more than new hay that causes allergic reactions.

This medication has been prescribed with your specific condition in mind as well as your vital statistics and overall health. Do not use more of it or use it more frequently than prescribed by your doctor. Changing the prescribed dose will not increase the effectiveness and may compromise the safety of the treatment.

Triamcinolone is a nasal spray, intended for use only in the nose. Do not get this medicine in your eyes or mouth; if it does, rinse with clear water and contact your health care provider immediately.

To use the spray, blow your nose if needed then shake the bottle gently. Tilt your head back slightly and insert the tip into your nostril, closing the opposite nostril with a finger. Spray once while breathing in gently. Hold your breath for a few seconds then exhale through your mouth. Repeat on the opposite nostril. Wipe the tip of the bottle with a clean, dry tissue or cloth and replace the cap.

If it is the first time you've used the spray bottle, or if you haven't used it for several days, you will need to prime the spray by pressing down fully on the pump five times or until a fine spray comes out. Note that a chart is included in the Triamcinolone package to keep track of the number of sprays you have used. After 120 sprays, throw away the Triamcinolone spray bottle as it most likely contains no medicine at this point.

Different patients will be prescribed different amounts of Triamcinolone. Patients should follow the doctor's instructions which are printed on the label. The following information is an average dose of Triamcinolone; your dose may be different.

Adults and teenagers are generally advised to spray twice in each nostril once per day. Each spray contains 55 micrograms of Triamcinolone. Children 2 to 12 years old are typically prescribed one spray in each nostril once per day. Adjustments to these amounts may be made during the course of treatment if required. Children who are under 2 years of age are typically not prescribed treatments of Triamcinolone.

Missing a dose does not mean that you should make it up when it is close to the time for the next dose. Doubling doses of Triamcinolone could cause unwanted overdose side effects and compromise the safety of this medication.

Having other medical issues while being treated with Triamcinolone may cause an increase in unwanted side effects or affect the safety or effectiveness of this medication. Inform your physician if you have been diagnosed with or suffer from the symptoms of the following conditions:

Triamcinolone may worsen the severity of these conditions as it affects the immune system and the ability to heal. It is of critical importance that your disclose your full medical history as well as details of any drugs you are currently taking or have taken in the recent past before you begin a course of treatment with Triamcinolone or any other drug. Include all prescription and non-prescription medications you may be taking including details of any vitamin, herbal or holistic supplements or treatments you are currently taking or have taken in the past.

Patients are urged to fully disclose all prescription and non-prescription drugs they are currently taking or have taken in the recent past as well as any vitamin, herbal or holistic supplements and remedies they are on during treatment with Triamcinolone.


Your doctor will want to see you for progress checks while you are in treatment with Triamcinolone to make sure your symptoms are improving. If three weeks of treatment have been completed without showing improvement in your symptoms or if your symptoms become worse, notify your doctor immediately.

Triamcinolone may have adverse effects in the nose. If you experience bloody mucus, nose sores, a whistling noise when breathing or unexplained nosebleeds, notify your doctor immediately.

A type of fungus infection in the nose and/or throat by the name of thrush is also something that users of Triamcinolone are at a higher risk for. If you have pain while eating or swallowing or exhibit white patches in your throat, notify your doctor immediately.

Any changes to your vision such as blurred vision, difficulty reading or eye pain should be reported to your health care provider, who may want to perform an eye exam.

While you are using Triamcinolone, you may get infections more easily. Avoid people who are sick or have viral infections such as measles or chickenpox, especially if you have never had these viruses before or been immunized.

As Triamcinolone mimics the actions of your adrenal gland by making steroids for your body, your adrenal gland may become less active than normal while you are on this treatment. This is more likely for patients who have been on this treatment for a long period of time but if you experience any darkening of the skin, dizziness, diarrhea, fainting, appetite loss, depression, nausea, rashes on the skin or any tiredness or weakness or vomiting, report these to your health care provider immediately.

Triamcinolone may affect growth in your child, so children being treated with Triamcinolone should be monitored for growth progress and proper weight gain while on this course of treatment.


To properly and safely store Triamcinolone nasal spray medication, keep it in the original packaging with the container closed at room temperature. Do not expose Triamcinolone to excessive heat, light or moisture and never allow it to freeze. This and all medications should be kept out of sight and reach of children. When it comes time to dispose of expired or unused Triamcinolone, consult your doctor or pharmacist for the safest way to do so.


Triamcinolone nasal spray is prescribed to patients suffering from seasonal allergies, perennial allergies, allergic rhinitis and/or hay fever for relief of nasal symptoms such as runny, itchy nose and sneezing. Patients suffering from seasonal allergies have often had the issue for many years, so regular treatment with Triamcinolone will most likely be started two to three weeks from the onset of allergy season, as it takes the medicine a certain period of time to work.

Triamcinolone is a corticosteroid medication that mimics the body's own production of hormones that fight inflammation due to environmental irritation. By creating a higher level than the steroid hormones normally found in the body, the Triamcinolone is able to combat symptoms of inflammation normally too strong for the body to do on its own.

Triamcinolone should be taken only as directed to avoid the risk of overdose or unwanted side effects. Prescribed dosage is based on your overall health and condition as well as the severity of your symptoms among other factors. Follow doctor's instructions, found printed on the label, for size of dose as well as frequency and duration of treatment.

Some normal side effects will be experienced but they are usually mild and require no medical attention. This medication may, however, increase the risk of unwanted effects in the nose which manifest themselves as nosebleeds, sores in the nose and bloody mucus. These symptoms should be reported to your doctor. Patients may contract a fungal infection called thrush which has symptoms of painful swallowing and white patches in the throat. Your doctor will need to know these symptoms so that treatment can be adjusted. Triamcinolone may affect vision, so report symptoms of blurred vision and eye pain to your doctor immediately.

Triamcinolone increases your risk for infections as well as affects the adrenal gland with long term use. Report any symptoms that are severe or prolonged to your health care professional immediately especially if they include skin changes, dizziness and fainting or depression.

Store your Triamcinolone medication away from heat, light and moisture in the original packaging at room temperature, taking care to keep it out of sight and reach of children. Dispose of unused or expired Triamcinolone according to the advice of your doctor or pharmacist.
