Nasonex® Aqueous Nasal Spray for Allergic Rhinitis

This nasal corticosteroid helps relieve sneezing, congestion, and runny nose from allergies and can reduce nasal polyp symptoms. Here you can learn how it works, who it suits, and how to use it safely. We support US delivery from Canada for your orders, including options for paying without insurance.

What Nasonex Is and How It Works

Nasonex® contains mometasone furoate, a steroid that reduces inflammation inside the nose. It targets local nasal pathways to lessen swelling and mucus, which can ease stuffiness and sneezing. On the label, Mometasone Furoate Nasal Spray 50 mcg is described as a glucocorticoid that inhibits multiple inflammatory mediators.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

The treatment is applied directly to the nasal lining. It acts mainly in the nose with low systemic exposure when used as directed. Regular use as prescribed may help maintain symptom control through allergy seasons or during chronic polyp management.

Who It’s For

Nasonex Aqueous Nasal Spray for allergies is indicated for seasonal and perennial allergic rhinitis in adults and in children where approved. It is also used for nasal polyps in adults. People with chronic nasal symptoms may benefit when antihistamines alone are not enough. See our condition pages on Allergic Rhinitis and Nasal Polyps for context.

Avoid this medicine if you are allergic to mometasone or any component of the spray. Talk to a clinician before use if you have a current nasal infection, recent nasal surgery or trauma, frequent nosebleeds, untreated tuberculosis, or active eye conditions like glaucoma. Children using intranasal steroids should be monitored for growth by a healthcare professional.

Dosage and Usage

Follow the directions on your prescription label. Typical schedules include once-daily dosing for allergic rhinitis. Some adults with polyps may use a higher frequency based on approved labeling. Use the lowest dose that keeps symptoms controlled, as directed by your prescriber.

Priming and steps for use:

• Prime the pump before first use and if not used for several days.
• Blow your nose gently to clear passages before each dose.
• Shake the bottle, insert the tip into one nostril, and aim slightly outward.
• Press to spray while breathing in gently; avoid sniffing hard.
• Repeat for the other nostril as directed.
• Wipe the tip and replace the cap after each use.

Do not spray into eyes or mouth. If the spray gets clogged, follow the label’s cleaning instructions and never try to unblock it with a pin. Use of Mometasone aqueous nasal spray is long-term for some patients; regular daily use often helps prevent breakthrough symptoms.

Strengths and Forms

The aqueous formulation delivers 50 mcg of mometasone furoate per actuation. Bottles commonly provide multiple doses, including sizes described on labels such as Nasonex Nasal Spray 120 sprays. Generic mometasone is available in many markets. Packaging and labeling can vary by country and manufacturer. Availability on our site may change over time.

Missed Dose and Timing

If you miss a dose, use it when you remember. If it is almost time for your next scheduled dose, skip the missed one and resume your regular schedule. Do not double up to make up for a missed spray. Try to use the spray at the same time each day for consistency.

Storage and Travel Basics

Store the bottle at room temperature per the official label. Keep it upright with the cap on, and protect it from excessive heat, cold, and direct light. Do not freeze. Keep out of reach of children and pets. If you travel, pack the spray in your carry-on with your prescription details. Avoid crushing the bottle and keep the nozzle clean. Our partners use temperature-controlled handling when required for select products.

Benefits

This medicine treats nasal symptoms at their source. It helps reduce swelling, mucus, and irritation that drive congestion and sneezing. Many people find once-daily dosing convenient for ongoing control. The aqueous base is designed for comfort and consistent dosing. It can be used alongside non-sedating antihistamines like Claritin when a clinician recommends combination therapy for broader symptom relief.

Side Effects and Safety

• Nasal irritation or burning
• Headache
• Nosebleeds
• Sore throat
• Cough
• Upper respiratory symptoms

Serious but uncommon risks include hypersensitivity reactions, nasal septum perforation, delayed wound healing, and local Candida infection. Long-term or high-dose steroid exposure can affect eye health or, in rare cases, adrenal function. Contact a healthcare professional if you experience persistent nosebleeds, vision changes, severe facial pain, or signs of infection. If you also use insulin or sulfonylureas, note that this local therapy is not an insulin or systemic steroid, but overall steroid exposure should still be considered in clinical decisions.

Drug Interactions and Cautions

Discuss all medicines you take with your prescriber. Strong CYP3A4 inhibitors such as ritonavir or cobicistat may increase steroid exposure and the risk of systemic effects. Using multiple corticosteroids at once can raise overall steroid burden. Tell your clinician about recent nasal surgery, frequent infections, glaucoma, cataracts, or any immune system concerns. Avoid live vaccines without medical guidance while on steroid therapies.

What to Expect Over Time

With regular use, symptoms often ease as airway inflammation settles. Some people notice improvement within the first day, while the full effect may build with continued use. Consistency matters. Use the spray daily as directed, track your symptoms, and bring notes to check-ins with your clinician. If control remains partial, your prescriber may adjust timing, suggest add-on therapies, or reassess triggers such as dust exposure or seasonal pollen counts. See practical strategies in our article Sinus Headaches Tips when sinus pressure complicates allergy seasons.

Compare With Alternatives

Another option in the same class is Omnaris Nasal Spray (ciclesonide), an intranasal corticosteroid with once- or twice-daily schedules per label. Many patients also consider a generic equivalent such as Mometasone Nasal Spray for similar active ingredient access. Oral or sublingual allergy immunotherapy may suit select patients under specialist care.

Patient Suitability and Cost-Saving Tips

Good candidates include adults with seasonal or perennial allergic rhinitis who need steady control and adults with nasal polyps under care. People with frequent nosebleeds, recent nasal surgery, or active infections should consult a clinician before starting. For children, a healthcare professional should confirm the age-appropriate indication and monitor growth.
