⚡ Quick Answer — What is Arzep Nasal Spray?
Arzep Nasal Spray is a combined nasal spray containing azelastine hydrochloride (a fast-acting intranasal antihistamine, 137 µg/spray) and fluticasone propionate (an intranasal corticosteroid, 50 µg/spray). Originator brand: Dymista (Meda/Viatris). It is the most effective single treatment for moderate-to-severe allergic rhinitis — superior to either component alone in head-to-head trials (MP-AzeFlu programme). Used for hay fever and perennial allergic rhinitis not controlled by single-agent therapy. Dose: 1 spray in each nostril twice daily. Onset within minutes for symptom relief (from azelastine), with full anti-inflammatory effect building over 1–2 weeks (from fluticasone). Main side effects: bitter taste (common with azelastine), nasal irritation, occasional epistaxis. Age 6+ in most markets.

What Is Arzep Nasal Spray?
Arzep Nasal Spray is a metered-dose aqueous nasal spray combining two allergy medicines in one device:
- Azelastine hydrochloride — an intranasal H1 antihistamine, 137 µg per spray
- Fluticasone propionate — an intranasal corticosteroid, 50 µg per spray
Manufactured by WHO-GMP certified manufacturer; supplied as 1, 2 or 3 bottles (10 mL / ~120 doses each). Total strengths per actuation: Azelastine 137 µg + Fluticasone propionate 50 µg per spray. The originator brand is Dymista, approved by the FDA and EMA in 2012 for moderate-to-severe allergic rhinitis not responsive to intranasal corticosteroid or oral antihistamine alone.
What Is Arzep Nasal Spray Used For?
- Moderate-to-severe seasonal allergic rhinitis (hay fever) where single-agent therapy has failed
- Perennial allergic rhinitis (year-round, dust-mite or mould driven)
- Mixed rhinitis — patients with both allergic and non-allergic components
- Step-up treatment when mometasone/fluticasone nasal spray alone is not enough
It treats all four cardinal symptoms of allergic rhinitis — sneezing, runny nose, itchy nose, and nasal congestion — and also relieves associated eye symptoms through systemic and topical mechanisms.
How Does Arzep Nasal Spray Work?
The two components attack allergic inflammation through complementary mechanisms:
- Azelastine is a selective H1 antihistamine that also stabilises mast cells and reduces eosinophil activation. Applied directly in the nose, it delivers symptom relief within minutes — much faster than any oral antihistamine. It also has mild anti-leukotriene and anti-ICAM-1 effects.
- Fluticasone propionate is a potent intranasal corticosteroid that binds glucocorticoid receptors in the nasal mucosa, suppressing cytokine and chemokine production, reducing eosinophil infiltration, and downregulating the late-phase allergic response. Near-zero systemic absorption (< 0.5% bioavailable).
In head-to-head randomised trials (the MP-AzeFlu programme), the combination was more effective than either component alone for both total nasal and total ocular symptom scores, and worked faster. This is why it is reserved as a step-up option when single-agent therapy is not enough.
Dosage and Administration
Adults and children aged 12+: 1 spray in each nostril twice daily — morning and evening. Total daily dose: 2 sprays per nostril per day.
Children 6–11 years: 1 spray in each nostril twice daily, subject to prescriber approval (labelling differs by country).
Technique:
- Prime the bottle before first use — shake gently, then press the pump until a fine mist appears (usually 6–10 priming sprays). Re-prime (2 sprays) if not used for 14+ days.
- Blow your nose gently before each dose.
- Hold the bottle upright and tilt your head forward slightly.
- Insert the nozzle into one nostril, angled away from the nasal septum (toward the outer wall of the nose).
- Breathe in gently through the nose while pressing the pump once; avoid sniffing hard.
- Repeat in the other nostril.
- Do not tilt your head back after the spray — this is the main cause of the bitter taste.
- Wipe the nozzle with a clean tissue and replace the cap.
Missed dose: take as soon as you remember. If it is nearly time for the next dose, skip and continue as normal.
Side Effects
Common:
- Bitter or metallic taste — the most common complaint (from azelastine dripping down the throat). Minimise by spraying with the head tilted forward, not back.
- Nasal irritation, mild burning or stinging
- Mild epistaxis (nosebleeds) — usually prevented by angling the nozzle outward
- Headache
- Mild sedation (rare from intranasal azelastine, but possible)
Uncommon:
- Nasal dryness, crusting
- Cough, throat irritation
- Altered smell or taste
- Nasal septum perforation — very rare; associated with aggressive technique or pre-existing septal weakness
- Candida (thrush) of the mouth or nose — rare
- Cataracts or raised intraocular pressure — rare with intranasal use; eye checks sensible for long-term users
- Hypersensitivity reactions
Systemic absorption of both components is very low, so the systemic corticosteroid and antihistamine side-effect burden is minimal compared with oral therapies.
Drug Interactions
- Strong CYP3A4 inhibitors (ritonavir, ketoconazole, itraconazole, clarithromycin) — can raise fluticasone systemic levels modestly; rarely clinically significant at intranasal doses but avoid in chronic use.
- Alcohol, sedating medicines — very low risk with intranasal azelastine, but possible additive drowsiness at higher than labelled doses.
- Other intranasal or oral corticosteroids — cumulative systemic steroid exposure if combined long-term; discuss with your prescriber.
- Live vaccines — no meaningful interaction at intranasal doses.
Who Should Not Use Arzep Nasal Spray?
- Known hypersensitivity to azelastine, fluticasone, or any excipient
- Untreated local nasal infection (bacterial, fungal, herpes) — treat first
- Recent nasal surgery, trauma, or septal ulcers — avoid until healed
- Children below the label age cutoff for your country
- Pregnancy and breastfeeding — use only when clinically necessary; discuss with a clinician
Storage
Store Arzep Nasal Spray below 25°C in an upright position, in a dry place. Do not freeze. Keep out of reach of children. Discard per the in-use expiry on the label after first opening (commonly 3 months after first use, but check the label).
Frequently Asked Questions
Is Arzep Nasal Spray the same as Dymista?
Yes — Arzep Nasal Spray contains the same two active ingredients (azelastine 137 µg + fluticasone propionate 50 µg per spray) as Dymista (Meda/Viatris). Bioequivalence is required by regulatory authorities, so clinical effect is the same at the same dose.
When should I step up to a combination spray like Arzep Nasal Spray?
Current guidelines (ARIA, AAAAI) recommend stepping up to an azelastine + fluticasone combination when single-agent intranasal corticosteroid (mometasone, fluticasone, budesonide) or oral antihistamine alone is not controlling moderate-to-severe symptoms after 2–4 weeks of consistent daily use. It is also first-line for severe seasonal hay fever where fast onset matters.
Why does Arzep Nasal Spray taste bitter?
The bitterness is azelastine dripping down the throat. Two techniques minimise it: spray with your head tilted forward (not back), and breathe in gently rather than sniffing hard — the medicine should stay in the nose, not run down the back.
How fast does Arzep Nasal Spray work?
Azelastine provides symptom relief within minutes. Fluticasone’s anti-inflammatory effect takes 6–12 hours to start and 1–2 weeks to peak. The combination gives you both: fast relief today plus building control over two weeks.
Can I use Arzep Nasal Spray long-term?
Yes — long-term daily use is well-studied. Systemic absorption of both components is very low. For children, use the lowest effective dose and monitor growth periodically.
Can I combine Arzep Nasal Spray with an oral antihistamine?
Yes if clinically indicated, but usually unnecessary — Arzep Nasal Spray already includes an intranasal antihistamine. Adding an oral 2nd-generation antihistamine (loratadine, cetirizine, fexofenadine) is reasonable for severe symptoms or when eye symptoms are prominent.
Where can I buy Arzep Nasal Spray online?
You can order Arzep Nasal Spray (Azelastine 137 µg + Fluticasone propionate 50 µg per spray) from MedsBase as 1, 2 or 3 bottles (10 mL / ~120 doses each). We ship worldwide with discreet packaging and genuine WHO-GMP certified manufacturer stock.
