It's used once daily and typically lasts for 24 hours. Nasacort (triamcinolone acetonide) doesn't have many side effects, but you might have a temporary sore throat or cough after you use it. Nasacort (triamcinolone acetonide) is available over the counter as a brand-name and generic medication.
Hay fever and allergy symptoms (nasal congestion, runny nose, sneezing, and itchy nose)
Nasacort (triamcinolone acetonide) is a corticosteroid (or steroid). When you come into contact with anything that causes allergies (such as the outdoors or animals), your immune system overreacts to try to get rid of the irritants from your body. This causes inflammation in your nose, leading to symptoms such as nasal congestion and itchy nose. Nasacort (triamcinolone acetonide) works by lowering inflammation in your nose. This helps relieve nasal allergy symptoms, such as runny nose, sneezing, and itchy nose.

Tell your healthcare provider before using Nasacort (triamcinolone acetonide) if you're taking other corticosteroids for other medical conditions, such as asthma, allergies, or skin rash. Your provider can make sure that taking more than one corticosteroid medication at the same time is safe for you.
Before using Nasacort (triamcinolone acetonide), it's important to review the directions on how to use the Nasacort (triamcinolone acetonide) nasal spray properly. Check the package instructions and follow their steps.
You'll need to "prime" each new spray bottle before you first use it and if you haven't used an opened bottle for more than 2 weeks. Priming makes sure you get your full dose of medication with a new bottle (or if you haven't used it in awhile). To prime your spray bottle, shake it well, and press and release the spray nozzle until you see a fine mist.
Shake your Nasacort (triamcinolone acetonide) spray bottle well before each use. Place the spray nozzle straight into the nose to aim it towards the back of your nose. Avoid pointing it towards the wall between the two nostrils (nasal septum).
Sniff gently while you spray Nasacort (triamcinolone acetonide) into each nostril. Watch children under the age of 12 closely to make sure they're using the nasal spray properly.
Try to avoid blowing your nose for 15 minutes after using Nasacort (triamcinolone acetonide). This prevents you from losing any of your dose.
If the pump on your Nasacort (triamcinolone acetonide) bottle isn't spraying properly, the spray nozzle might be blocked. You shouldn't unblock the nozzle with a pin or any other object. Instead, pull the nozzle apart from the bottle and rinse it with warm water to help unblock it. Once it's reattached to the bottle, test the spray nozzle by pressing and releasing it until you see a fine mist.
Only spray Nasacort (triamcinolone acetonide) into your nose. Don't spray the medication into any other parts of your body, such as the eyes or mouth, as this can be harmful. If it accidentally gets in your eyes, rinse them well with water.
It's important that you don't share your Nasacort (triamcinolone acetonide) spray bottle with anyone else because this can spread germs and lead to infections.
If your allergy symptoms don't get better after using Nasacort (triamcinolone acetonide) for 1 week, stop using the medication and talk to your healthcare provider. They can check to see if there's another problem going on.
Nasacort (triamcinolone acetonide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Recent nose ulcer, surgery, or injury
If you've recently had a nose ulcer, nose surgery, or a nose injury and it hasn't fully healed yet, let your healthcare provider know before starting Nasacort (triamcinolone acetonide). The medication gets sprayed directly into the nose, so it can cause irritation or affect wound healing. Your provider might recommend to wait until your nose is completely healed before you use Nasacort (triamcinolone acetonide). Though rare, using Nasacort (triamcinolone acetonide) directly in the nose might also cause nasal septum perforation (a hole that forms in the tissue of your nose separating the two nostrils). Let your healthcare provider know if you hear a whistling sound from your nose when you breathe, as it can be a sign of this problem. In addition, if you have severe or frequent nosebleeds, stop using Nasacort (triamcinolone acetonide) and let your provider know.
Risk factors: History of glaucoma or cataracts
Risk factors: Not current on vaccinations | Taking medications that weaken the immune system | Long-term use of Nasacort (triamcinolone acetonide)
Nasacort (triamcinolone acetonide) can lower your body’s ability to fight off infections and potentially worsen any infections you already have. Be careful not to come in contact with anyone who has chickenpox, measles, or tuberculosis (TB); and tell your healthcare provider if you do. Talk to your provider before using Nasacort (triamcinolone acetonide) if you currently have a respiratory tract infection; any fungal, bacterial, viral, or parasitic infections; or active or inactive TB. Call your provider right away if you develop a new infection with a fever that doesn't go away while you're using Nasacort (triamcinolone acetonide).
Using Nasacort (triamcinolone acetonide) for several months or longer can also raise your risk of getting a fungal infection in the nose or throat. Let your provider know if you notice pain or soreness in the nose or throat while you're using Nasacort (triamcinolone acetonide). Your provider can check to see if you have a fungal infection in the nose or throat and recommend appropriate treatment.
Risk factors: Children under age 12 | Using Nasacort (triamcinolone acetonide) longer than 2 months
Steroids like Nasacort (triamcinolone acetonide) can cause slowed growth and development in some children, especially in those who need to use the nasal spray for longer than 2 months per year. To prevent slowed growth, make sure your child uses the lowest dose possible to relieve their allergy symptoms. If you're worried about your child's growth, talk to their healthcare provider about other treatment options.
Each spray contains 55 mcg of triamcinolone.
Adults and children 12 years or older: The typical dose is 2 sprays in each nostril once daily. Once allergy symptoms improve, you can lower your dose to 1 spray in each nostril once daily.
Children ages 6 to 11 years: The typical dose is 1 spray in each nostril once daily. If allergy symptoms don't improve, your child can use 2 sprays in each nostril once daily until their allergies get better. Then, return to the typical dose of 1 spray in each nostril once daily.
Children ages 2 to 5 years: The typical dose is 1 spray in each nostril once daily.
Children younger than 2 years of age: Nasacort (triamcinolone acetonide) isn't recommended for this age group. Discuss other allergy medications with your child's healthcare provider.
