What to Know About Nasacort Allergy 24HR (Triamcinolone Nasal)

Nasacort Allergy 24HR (triamcinolone) is an over-the-counter (OTC) nasal spray used to treat allergy symptoms such as sneezing and congestion. It belongs to the corticosteroid class of medications, which prevent the immune system from producing cytokines—inflammation-triggering chemicals that contribute to nasal symptoms—in response to exposure to an allergen.

Nasacort Allergy 24HR is also available in generic form. Many pharmacies and retailers have store-brand versions of triamcinolone, as well.

Uses

Once available only by prescription, the OTC version of Nasacort Allergy 24HR was introduced in October 2013. It is used to treat certain symptoms of allergic rhinitis (hay fever) and other allergies, including:

• Sneezing
• Nasal congestion
• Runny nose
• Itchy nose
• Watery eyes

When used at bedtime, Nasacort Allergy 24HR also may help relieve sleep issues that arise due to allergies.

Before Taking

Although you don't need to see your healthcare provider before purchasing OTC Nasacort Allergy 24HR, it is a good idea to ask if your practitioner advises this treatment.

Aside from price and packaging, there are no discernible differences between Nasacort Allergy 24HR and generic triamcinolone nasal spray. Both should work equally well to relieve allergy symptoms.

Precautions and Contraindications

Nasacort Allergy 24HR is safe for most people. Because it is sprayed directly into the nose, however, you should ask your healthcare provider before using it if you:

• Have an open sore or ulcer in your nose
• Get frequent nosebleeds
• Have recently had sinus surgery or another procedure in or around your nose that you are still healing from

Other potential contraindications for using Nasacort Allergy 24HR include:

• Certain eye conditions, namely increased intraocular pressure, glaucoma (a group of eye conditions that damage the optic nerve), or cataracts (clouding of the lens of the eye)
• An untreated infection-in particular ocular herpes simplex (viral infection affecting the eyes) or tuberculosis (bacterial infection)
• Recent exposure to measles or varicella (chicken pox)

If you're pregnant, trying to conceive, or nursing, you should check with your healthcare provider before using Nasacort Allergy 24HR. If you become pregnant while using Nasacort Allergy 24HR, let your healthcare provider know.

The same is true if you're already taking any other type of steroid medication (to treat asthma or a rash, for example).

Avoid this medication if you're allergic to triamcinolone or any of the ingredients listed on the Nasacort Allergy 24HR package label.

Other Options

If Nasacort Allergy 24HR isn't safe for you or if it isn't effective for treating your symptoms, there are other medications that treat nasal allergy symptoms that you can try. These include OTC steroidal nasal sprays such as Flonase (fluticasone) and Rhinocort (budesomide).

Nonsteroidal options include oral antihistamines like Claritin (loratadine), Zyrtec (cetirizine), and Allegra (fexofenadine).

The antihistamine nasal spray Astepro (azelastine) is another OTC alternative. It's also available as a generic.

Dosage

One spray of Nasacort Allergy 24HR contains 55 micrograms (mcg) of the active ingredient, triamcinolone, a corticosteroid that's also used to treat conditions such as asthma.

Nasacort Allergy 24HR is formulated to be used once per day. According to the manufacturer, Chattem, Inc. (a subsidiary of Sanofi), the starting dosage for adults and children 12 and older is two sprays per nostril daily.

Once symptoms improve, the daily dosage should be decreased to one spray per nostril.

Modifications

Nasacort Allergy 24HR is safe for children as young as 2 years old, and the dosage for young children differs from the dose that's recommended for people over age 12.

A children's version of the product is available that also contains 55 micrograms of glucocorticoid.

• Children 6–12: Use one spray per nostril daily. If symptoms don't improve, increase to two sprays, returning to the single-spray dose once symptoms subside.
• Children 2–6: Use one spray per nostril daily. Children this age will need an adult's help and supervision to use Nasacort Allergy 24HR.

All listed dosages are according to the drug manufacturer. Talk to your healthcare provider or pharmacist to determine the right dose for you or your child.

How to Take and Store

The first time you use a bottle of Nasacort Allergy 24HR, you must prime it by pressing and releasing the nozzle until a fine mist is released. This may take several pumps.

To take:

• Blow your nose gently to clear out mucus before using the spray. Tilt your head forward slightly.
• Insert the nozzle into your nostril angling it away from the center of your nose toward your ear, ensuring the spray reaches the back of your nose.
• Use your finger to close off your other nostril by pushing gently on the outside of your nose.
• Press the nozzle to activate the spray, sniffing in gently as the medication is released.

Do not blow your nose for 15 minutes after taking Nasacort Allergy 24HR.

If the nozzle becomes blocked and to clean it, remove the nozzle and soak it (not the rest of the bottle) in warm water for a few minutes.

Side Effects

As with any drug, there is the potential for harmful side effects from using Nasacort Allergy 24HR. Although the chances of experiencing most of them are low, it's important to know what to look out for.

Common

The most likely side effects of using Nasacort Allergy 24HR are:

• Sore throat
• Nosebleeds (epistaxis)
• Cough
• Headache

Severe

There are a number of rare, but serious side effects associated with the long-term use of Nasacort Allergy 24HR:

• Nasal septal perforation (a hole in the cartilage that separates the nostrils)

• Glaucoma
• Cataracts
• Elevated cortisol levels

If you experience any side effects or problems with Nasacort Allergy 24HR, stop using it, and contact your healthcare provider for further instruction.

Warnings and Interactions

For this reason, children and teens who use Nasacort Allergy 24HR for long periods of time should be monitored by their healthcare provider.
