Generic Azelastine Information

Introduction

Azelastine is a second‑generation antihistamine indicated for the relief of allergic rhinitis and allergic conjunctivitis. In the United Kingdom it is available as a nasal spray for hay‑fever and perennial nasal allergy, and as ophthalmic drops for itchy, watery eyes caused by seasonal or perennial allergens. The medicine belongs to the allergy therapeutic group and is supplied by several manufacturers worldwide. Its primary purpose is to block the action of histamine, the chemical released during an allergic response, thereby reducing symptoms such as sneezing, nasal congestion, itching, and ocular irritation.

What is Azelastine?

Azelastine is the generic name of the active compound azelastine hydrochloride. It was first developed by Allergan (now part of AbbVie) and later licensed to multiple pharmaceutical companies for formulation as a nasal spray and ophthalmic solution.

Azelastine is the generic version of Astepro (nasal spray) and Patanol / Optivar (eye drops), containing the same active compound Azelastine. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

The drug is classified as a selective histamine H₁‑receptor antagonist with additional mast‑cell stabilising properties. It is marketed in the UK in .1 % (1 mg/mL) nasal spray bottles and .05 % (.5 mg/mL) ophthalmic solution bottles, each packaged in child‑ resistant containers in accordance with MHRA regulations.

How Azelastine Works

Azelastine binds competitively to peripheral H₁‑histamine receptors on sensory nerve endings in the nasal mucosa and conjunctiva. By preventing histamine from activating these receptors, the drug stops the cascade that leads to vasodilation, increased vascular permeability, and nerve stimulation – the physiological basis for itching, redness, and swelling.

In addition to H₁ antagonism, azelastine inhibits the release of inflammatory mediators such as leukotrienes, prostaglandins, and cytokines from mast cells and basophils. This dual action explains its relatively rapid onset of symptom relief (often within 15 minutes) and its prolonged effect, typically lasting 8–12 hours after a single dose. The drug is metabolised primarily by the cytochrome P450 enzyme CYP3A4 and excreted unchanged in the urine and faeces, resulting in a terminal half‑life of approximately 22 hours.

Conditions Treated with Azelastine

• Seasonal allergic rhinitis (hay‑fever). In the UK, over 20 % of adults experience seasonal pollen allergy each year, leading to substantial NHS consultations. Azelastine nasal spray reduces sneezing, nasal itching, rhinorrhoea, and congestion.
• Perennial allergic rhinitis. Indoor allergens such as house dust mite, pet dander, or mould cause year‑round symptoms. The nasal formulation provides consistent control without the sedative effects associated with first‑generation antihistamines.
• Allergic conjunctivitis. The ophthalmic solution relieves ocular itching, tearing, and redness caused by pollen, dust, or animal allergens. Clinical trials have demonstrated comparable efficacy to cromolyn sodium eye drops with a more convenient dosing schedule.
• Non‑allergic rhinitis (occasionally). Although not a licensed indication, azelastine’s anti‑inflammatory properties may benefit patients with vasomotor rhinitis; clinicians sometimes use it off‑label under specialist guidance.

Who is Azelastine For?

Azelastine is appropriate for adults (≥ 18 years) who require rapid, non‑sedating relief from allergic nasal or ocular symptoms. It is particularly useful for:

• Individuals whose symptoms persist despite avoidance measures or intranasal corticosteroids at low doses.
• Patients who experience drowsiness with first‑generation antihistamines and need a daytime‑friendly option.
• Those who prefer a topical route (nasal spray or eye drops) to avoid systemic medication load.

Azelastine is not recommended for:

• Children under 18 years (unless prescribed off‑label by a specialist).
• Pregnant or breastfeeding women without medical supervision, as safety data are limited.
• Patients with known hypersensitivity to azelastine or any excipients in the formulation.

Risks, Side Effects, and Interactions

Common

• Bitter taste (nasal spray) – reported in up to 25 % of users, usually transient.
• Mild nasal irritation or burning – occasional stinging sensation after spray administration.
• Transient ocular discomfort (eye drops) – slight blurring or stinging that resolves within minutes.

Rare

• Headache – reported in ≤ 2 % of users, self‑limited.
• Dry mouth – occasional, related to anticholinergic activity.
• Epistaxis – rare nosebleed, usually linked to vigorous nose‑blowing after spray.

Serious

• Hypersensitivity reactions – angio‑edema, urticaria, or anaphylaxis (extremely rare). Immediate medical attention required.
• Cardiac arrhythmias – isolated case reports in patients with pre‑existing conduction disorders; monitor if high‑dose systemic exposure occurs (e.g., accidental overdose).

Drug‑Drug Interactions

• CYP3A4 inhibitors (ketoconazole, erythromycin, ritonavir) may increase systemic azelastine levels, though topical use limits clinical relevance.
• Sedating antihistamines or CNS depressants – additive sedation is unlikely with azelastine but caution is advised if patients are on multiple antihistamine agents.
• Anticholinergic drugs – may exacerbate dry‑mouth side effects.

Patients should always disclose all concurrent medications, including over‑the‑counter products and herbal supplements, to their healthcare professional.

Practical Use: Dosing, Missed Dose, Overdose

• Nasal spray (.1 %): Two sprays (one in each nostril) twice daily (morning and evening). Each spray delivers .05 mg of azelastine; total daily dose ≈ .2 mg.
• Eye drops (.05 %): One drop in each affected eye twice daily. Each drop contains .5 mg; total daily dose ≈ 1 mg.

Missed dose: If a scheduled dose is forgotten, administer it as soon as it is remembered provided that the usual dosing interval has not been exceeded by more than 4 hours. Do not double the subsequent dose.

Overdose: In the unlikely event of accidental ingestion of a large quantity of spray or drops, seek urgent medical advice or contact the UK Poison Information Service (UKPIS). Symptoms may include pronounced drowsiness, nausea, or cardiovascular effects, but serious toxicity is rare due to limited systemic absorption.

Precautions:

• Avoid alcohol or strong CNS depressants during the first few days while assessing individual tolerability.
• Do not use nasal spray immediately after nasal surgery or during an acute upper‑respiratory infection without consulting a physician.
• Store the product at 15‑30 °C, protected from light; do not freeze.

FAQ

• What is the difference between generic Azelastine and the brand‑name Astepro nasal spray?
  The generic version contains the same active compound, azelastine hydrochloride, in an identical concentration and dosage form. The primary differences lie in packaging, price, and the manufacturer’s branding, with the generic offering a lower cost to the patient.

• Can I travel internationally with Azelastine nasal spray in my hand luggage?
  Yes, provided the product remains in its original child‑ resistant container and you keep the prescription or a pharmacist’s label if requested by security. In the UK, nasal sprays are classified as non‑controlled medication, allowing carriage on flights.

• Does Azelastine require refrigeration?
  No, the medication should be stored at controlled room temperature (15‑30 °C) away from direct sunlight and moisture. Refrigeration is unnecessary and may affect the spray’s viscosity.

• Are there any excipients in the nasal spray that could trigger reactions?
  The spray contains benzalkonium chloride as a preservative, which can cause irritation in a small subset of patients with known sensitivity. If you experience persistent burning or redness, discontinue use and consult a pharmacist.

• How does the efficacy of Azelastine compare with intranasal corticosteroids?
  Intranasal corticosteroids generally provide superior anti‑inflammatory control for severe allergic rhinitis. Azelastine offers faster symptom relief with a non‑sedating profile, making it a useful adjunct or alternative for mild‑to‑moderate cases.

• Can I use Azelastine while wearing a CPAP mask for sleep apnoea?
  Yes, topical azelastine does not interfere with CPAP equipment. However, ensure the nasal passages are clear before applying the spray to avoid discomfort.

• Is it safe to use Azelastine eye drops before contact lens insertion?
  The drops should be instilled at least 10 minutes prior to inserting contact lenses to allow the formulation to absorb fully and reduce the risk of lens contamination.

• What are the legal limits for importing Azelastine for personal use in the UK?
  Personal importation of up to a three‑month supply (based on the prescribed daily dose) is permitted without a special licence, provided the medication is for personal use and not for resale.

• Does azelastine have any known effect on drug testing for employment or sport?
  Because azelastine is not a controlled substance and is not listed on standard doping panels, it does not typically trigger positive results in routine drug screens.

• Has the formulation of Azelastine changed over time?
  The core active ingredient and its concentration have remained consistent. Minor formulation adjustments, such as preservative concentration or propellant type, have been made to improve stability and spray performance, but these changes do not affect therapeutic efficacy.
