Nasonex® Aqueous Nasal Spray for Allergic Rhinitis and Nasal Polyps

What Nasonex® Is and How It Works

Nasonex Aqueous Nasal Spray is a corticosteroid for nose symptoms. It contains mometasone furoate 0.05% (50 mcg per spray). It treats seasonal and perennial allergic rhinitis and reduces nasal polyp size in adults. Many people compare the nasonex aqueous nasal spray price because this branded option is effective and often affordable without insurance. Nasonex reduces local inflammation in the nasal lining by blocking inflammatory mediators and cytokines. Less swelling means fewer symptoms like congestion, sneezing, itching, and runny nose.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba, and prescriptions are reviewed by licensed pharmacists before dispensing. We work with licensed, vetted international partner pharmacies to source authentic brand medications, offering a broad selection at competitive Canadian pricing.

Nasonex is an aqueous suspension delivered through a metered pump. For allergic rhinitis in adults and adolescents, dosing is once daily. Children 2–11 years also use once-daily dosing at a lower number of sprays. For nasal polyps in adults, higher total daily dosing is used. Relief may begin within the first day, and benefits increase over 1–2 weeks of regular use.

Dosage and Usage

• Active ingredient: mometasone furoate monohydrate 0.05% (50 mcg per spray).
• Allergic rhinitis, adults and adolescents 12+: 2 sprays in each nostril once daily (total 200 mcg/day).
• Allergic rhinitis, children 2–11: 1 spray in each nostril once daily (total 100 mcg/day).
• Prophylaxis of seasonal allergies: begin 2–4 weeks before expected pollen exposure.
• Nasal polyps, adults 18+: 2 sprays in each nostril twice daily (total 400 mcg/day). Once controlled, some patients may step down to once daily.
• Prime before first use: shake, then release 10 sprays until a fine mist appears.
• If unused for 1 week or more, reprime with 2 sprays.
• How to use: gently blow nose; shake bottle well; tilt head slightly forward; insert tip into nostril; aim away from septum; press pump while gently breathing in; breathe out through mouth.
• Avoid spraying into eyes or mouth. Do not share the device.
• Clean the nozzle weekly: remove the cap and tip, rinse in warm water, air dry, and reassemble. Do not try to unblock with a pin.
• Missed dose: use when remembered the same day; if near the next dose, skip the missed dose. Do not double doses.

• Storage temperature: store at 15–30 °C (59–86 °F). Do not freeze.
• Keep the cap on, bottle upright, and protect from direct sunlight.
• Do not refrigerate. Avoid excessive heat, such as a parked car.
• Travel: pack in carry-on luggage with the cap in place to prevent leakage.
• Track the spray counter or mark the start date to know when to reorder.
• Keep out of reach of children and pets.

Benefits and Savings

Nasonex can relieve congestion, sneezing, itching, and runny nose. It helps reduce nasal polyp size and improves airflow. Once-daily dosing for allergies is convenient. The aqueous formulation moisturizes while delivering consistent 50 mcg sprays. Many people find the nasonex aqueous nasal spray effectiveness comparable or superior to older intranasal steroids.

Buying through a Canadian pharmacy can offer substantial savings. Typical customers save 60–80% compared with common US retail prices. That value can help those paying cash or managing costs without insurance. You can also lower the per-month cost by choosing multi-month supplies when available.

Side Effects and Safety

• Common: nosebleeds (epistaxis), nasal irritation or burning, headache, sore throat, cough.
• Upper respiratory tract infection, sinusitis, or throat irritation.
• Unpleasant taste or smell, nasal dryness or crusting.
• Rare: nasal Candida infection (thrush) requiring antifungal treatment.
• Pediatrics: potential effect on growth with long-term use; monitoring may be advised.

Serious but uncommon risks include hypersensitivity reactions, increased intraocular pressure, glaucoma, cataracts, impaired wound healing, and nasal septum perforation. Avoid use after recent nasal surgery or trauma until healing is complete. Using intranasal steroids with strong CYP3A4 inhibitors (for example, ritonavir) may increase systemic steroid effects, though risk is low at recommended doses. Hypoglycemia is not associated with Nasonex alone.

Onset Time

Some people notice symptom relief within 12–24 hours of starting regular use. Congestion and sneezing often continue to improve over 1–2 weeks. For seasonal allergy prophylaxis, starting 2–4 weeks before pollen season provides the best control. In nasal polyps, reduction in polyp size and improved airflow may take several weeks, with continued gains over months when used consistently.

Compare With Alternatives

Intranasal corticosteroids have similar overall effectiveness, but response can vary by person. One option is Beclomethasone Nasal Spray, which treats allergic rhinitis with once- or twice-daily dosing. It may be a cost-conscious alternative if Nasonex is not preferred.

Another option is the generic form of Nasonex, Mometasone Nasal Spray. It delivers the same active ingredient and strength (50 mcg per spray) and may reduce the nasonex aqueous nasal spray cost while maintaining similar outcomes.

For those with significant itch and sneeze, an intranasal antihistamine such as azelastine may be used alone or combined with a steroid. Some people also use saline rinses to improve mucosal hydration and aid symptom control.

Combination Therapy

• Nasonex plus intranasal antihistamine for rapid relief of itch and sneeze.
• Nasonex plus oral antihistamine during peak pollen days.
• Nasonex with saline irrigation to reduce crusting and improve delivery.
• For polyps, Nasonex post-surgery as maintenance to reduce recurrence.
• Reduce doses of sedating antihistamines if side effects occur.

Patient Suitability and Cost-Saving Tips

Candidates include adults and children with seasonal or perennial allergic rhinitis, and adults with nasal polyps. Avoid if allergic to any component. Delay use after recent nasal surgery, trauma, or until ulcers heal. Use caution with a history of glaucoma or cataracts. Monitor growth in children who need long-term corticosteroids. People with active untreated infections, including tuberculosis or fungal infections, should not use intranasal steroids until these are controlled.

Pregnancy and lactation decisions should be individualized with a healthcare professional. For long-term users, periodic nasal exams can check for septal damage or infection. Those who wear contact lenses should monitor for eye irritation if accidental ocular exposure occurs.

You can set simple reorder reminders in your account to avoid gaps in therapy. Multi-bottle orders or multi-month supplies may lower the per-month price and reduce shipping costs. These options help whether using insurance or paying out of pocket, including those seeking the nasonex aqueous nasal spray cash price.
