Nasonex nasal spray (mometasone furoate)

Nasonex is a prescription nasal corticosteroid used to reduce inflammation from allergies and related nasal conditions. This page summarizes labeled uses, dosing basics, technique, and key safety information for Nasonex Aqueous Nasal Spray. It also explains access steps through our referral model, including US shipping from Canada, for cash-pay requests without insurance.

Information here is meant to support planning and safe handling. It does not replace the directions from the prescriber or the official product leaflet.

What Nasonex Aqueous Nasal Spray Is and How It Works

This medicine contains mometasone furoate, an intranasal corticosteroid (anti-inflammatory steroid spray) used to treat swelling and irritation inside the nose. By lowering local inflammation, it can reduce symptoms such as sneezing, runny nose, congestion, and itching. Effects are often gradual, so consistent daily use is typically needed to judge benefit.

Unlike decongestant sprays, this therapy is not designed for rapid, short-term “unblocking.” Instead, it targets the underlying inflammatory response that drives allergic rhinitis and some other nasal conditions. Because it is used in the nose, most exposure is local, but steroid-related risks can still occur, especially with prolonged use or higher-than-directed amounts.

Prescription details may be confirmed with your prescriber before referral.

Many people recognize it as a maintenance allergy nasal spray. If you are browsing related respiratory therapies, the Respiratory Category lists other prescription options dispensed through participating pharmacies.

Who It’s For

Nasonex Aqueous Nasal Spray may be prescribed for seasonal or year-round allergic rhinitis. Some labels also include treatment of nasal polyps (noncancerous growths in the nasal lining) in appropriate age groups. A clinician may also choose an intranasal steroid for other inflammatory nasal symptoms when clinically appropriate.

At a high level, it may not be suitable for people with hypersensitivity to mometasone or any ingredient in the spray. Caution is commonly advised after recent nasal surgery or trauma, because steroids can slow wound healing. People with untreated infections (including certain fungal, bacterial, or viral infections), tuberculosis exposure, or ocular herpes history may need additional screening or monitoring before use.

Why it matters: Persistent congestion can have multiple causes, and treatment can differ by diagnosis.

Dosage and Usage

Dosing is individualized and should follow the product monograph and the prescriber’s directions. For allergic rhinitis, labeled regimens commonly use once-daily dosing, with the number of sprays per nostril adjusted by age and response. For nasal polyps, some labels use different schedules. Do not change the schedule or number of sprays without medical direction, even if symptoms fluctuate.

Because technique affects how much medicine reaches the nasal lining, correct use is part of “dose.” If symptoms are not controlled, the issue can be timing, adherence, technique, or an alternate diagnosis rather than a need for self-adjustment.

Technique basics (pump, aiming, and cleaning)

Before first use, the pump is typically primed per the leaflet so it delivers a consistent spray. If the product has not been used for a period, re-priming may be needed. When spraying, the nozzle is usually aimed slightly outward (away from the nasal septum, the middle wall) to lower irritation and reduce the chance of nosebleeds. Gentle breathing in through the nose during actuation can help distribute the mist. After use, wiping the nozzle and keeping the cap on helps reduce clogging and contamination. If the spray seems blocked, follow the cleaning steps in the instructions rather than using sharp objects that may damage the pump.

When reviewing directions or documentation requirements, Nasonex Aqueous Nasal Spray is dispensed only with a valid prescription.

Strengths and Forms

This product is commonly supplied as a metered-dose aqueous spray that delivers a fixed amount of mometasone furoate per actuation (often described as 50 mcg per spray). Packaging may vary by market and may be described by the number of actuations in the bottle. Some listings refer to a 120-spray bottle with a pump, but availability can change over time.

The same active ingredient may also be available as a generic mometasone furoate nasal spray in certain regions. A clinician or pharmacist can confirm whether substitution is appropriate based on local rules, the prescription wording, and supply. For users comparing formats, it can help to check the labeled actuation count, priming instructions, and whether the bottle includes a consistent metering mechanism.

Storage and Travel Basics

Store the bottle as directed on the carton and product leaflet. In general, nasal steroid sprays are kept at controlled room temperature and protected from extremes (such as freezing or high heat). Keep the cap in place when not in use to help maintain hygiene and reduce nozzle blockage.

When traveling, keep the spray in its original packaging when possible, especially if you may need to show a prescription label. Avoid leaving it in a hot vehicle or in direct sunlight for extended periods. If you notice a change in spray pattern, unusual odor, visible particles, or damage to the nozzle, follow the manufacturer’s troubleshooting steps and consult a pharmacist for handling guidance.

Side Effects and Safety

Common side effects with intranasal steroids can include nasal irritation or burning, dryness, sore throat, headache, and nosebleeds. These effects are often technique-related, so reviewing aiming and avoiding spraying directly onto the septum can be helpful. If nosebleeds are frequent, prolonged, or heavy, medical evaluation is important to rule out injury or another cause.

More serious but less common risks can include nasal ulceration, septal perforation (a hole in the nasal wall), or slower healing after nasal procedures. Steroid effects on the eyes (such as cataracts or glaucoma) are possible with long-term use in some people. Allergic reactions can occur with any medicine and need urgent care if symptoms such as facial swelling or trouble breathing develop.

In pediatric use, clinicians may monitor growth over time because corticosteroids can affect growth velocity in some children. If Nasonex Aqueous Nasal Spray is used for extended periods, periodic review of ongoing need and symptom control is typical.

Drug Interactions and Cautions

Drug interactions with nasal mometasone are less common than with oral steroids, but they can still matter. Strong CYP3A4 inhibitors (medicines that slow steroid breakdown), such as ritonavir or cobicistat used in some HIV regimens, may increase systemic corticosteroid exposure and raise the risk of steroid-related adverse effects. Certain antifungals (for example, ketoconazole) may have similar concerns depending on dose and route.

Tell the prescriber and pharmacist about all prescription drugs, over-the-counter products, and supplements. This includes other steroid-containing products (inhalers, skin creams, or oral steroids), because combined exposure may increase the chance of systemic effects. Also mention chronic infections, immune suppression, or upcoming nasal surgery so the care team can weigh risks and set monitoring plans.

Compare With Alternatives

Intranasal corticosteroids are one of several options for allergic nasal symptoms. Alternatives can include other steroid sprays (such as fluticasone or budesonide), antihistamine nasal sprays (such as azelastine), oral antihistamines, saline rinses, and allergen-avoidance strategies. Choice depends on symptom pattern, comorbid asthma or sinus disease, tolerance, and response over time.

Some clinicians consider a leukotriene receptor antagonist (such as montelukast) for selected patients, especially when allergic rhinitis coexists with asthma symptoms. If that approach is being evaluated, Singulair is one example of a prescription product in that class. Nasonex Aqueous Nasal Spray remains in the intranasal steroid category, so comparisons should focus on route, expected onset, and safety considerations rather than assuming one approach fits all.

• Intranasal steroids: reduce nasal inflammation
• Antihistamine sprays: target histamine symptoms
• Oral antihistamines: systemic allergy relief
• Saline rinses: mechanical symptom support

Pricing and Access

Costs for nasal steroid sprays can vary by strength, brand versus generic availability, and pharmacy supply. Some people look for cash-pay options when coverage is limited. If you are exploring affordability resources, Low Income Prescription Help outlines practical steps that may reduce out-of-pocket burden.
