Astelin (Azelastine) – Patient Guide (UK)

Astelin is a brand name of azelastine, an antihistamine medicine used to treat allergy symptoms affecting the nose. It is available as a nasal spray and helps reduce sneezing, itching, and a runny or blocked nose caused by allergic rhinitis.

This guide is designed to help you understand how Astelin works, how to use it safely and effectively, and what to expect. Always follow the instructions provided with your product and the advice of a healthcare professional.

Quick Product Information

How Astelin Works (Mechanism of Action)

Astelin (azelastine) is a second-generation antihistamine. It works mainly by blocking histamine H1 receptors in the nasal tissues.

• Stops or reduces histamine-driven symptoms such as sneezing, itching, and runny nose.
• Helps calm inflammation within the nasal lining, which can contribute to ongoing symptoms.
• May reduce the release of inflammatory mediators involved in allergic responses.

Because it is administered directly to the nose, Astelin can provide targeted relief for nasal allergy symptoms.

What It’s Used For (Indications)

Astelin is used to treat symptoms of allergic rhinitis, which may include:

• Sneezing
• Runny nose (rhinorrhoea)
• Nasal itching
• Blocked or stuffy nose (nasal congestion)

Allergic rhinitis can be seasonal (e.g., pollen) or year-round (e.g., dust mites or pet dander). Astelin may be used when symptoms are present, as directed.

Pharmacokinetics (How the Body Handles It)

Pharmacokinetics describes what happens after you use the medicine—absorption, distribution, metabolism, and elimination.

• Absorption: Azelastine is delivered to the nasal mucosa. Some amount may be systemically absorbed after intranasal use.
• Distribution: Once absorbed, it distributes through the body tissues.
• Metabolism: Azelastine is metabolised in the liver (primarily by CYP-related pathways), producing active and inactive metabolites.
• Elimination: The medicine and its metabolites are eliminated mainly via the kidneys (urine) and partly through other routes.

In general, systemic exposure after nasal use is typically lower than with some oral formulations, but side effects can still occur, especially with sensitive individuals or if higher doses are used.

When to Take It (Timing & How Often)

Astelin nasal spray is used regularly to control symptoms during allergy seasons or when exposure to allergens triggers symptoms.

Typical timing:

• Many users find symptom control is improved when used consistently rather than only when symptoms become severe.
• For some people, using it morning and evening provides good coverage.

Important: Always check your exact product pack for the specific dose schedule recommended for your formulation.

Dosing (Adult Use)

Dose regimens can vary between formulations and countries. Use the directions on your specific product label. The information below is general.

• Adults and adolescents: commonly 1–2 sprays in each nostril per dosing session, typically once or twice daily, depending on symptom severity and product instructions.

If you miss a dose: Use it when you remember unless it is close to the next scheduled dose. Do not use extra spray to make up for a missed dose.

Do not exceed the stated daily dose. Using more than recommended does not necessarily improve results and may increase side effects.

Food Interactions

Because Astelin is a nasal medicine, food interactions are generally unlikely compared with oral medicines.

• Typical advice: You can usually take Astelin at any time, with or without food.
• Bitter taste: Some people notice a bitter taste after spraying, which is a formulation effect and not usually related to meals.

Alcohol and Medicine Interactions

Alcohol: While azelastine is mainly a local nasal treatment, some people may experience mild drowsiness or dizziness. If you notice any drowsiness, it is sensible to reduce or avoid alcohol, as it can worsen sedation and impair concentration.

Medicines that may interact: Interactions depend on your personal medicine list. In particular, be cautious with medicines that can cause drowsiness, including:

• Sedating antihistamines
• Some anti-anxiety medicines
• Sleeping tablets
• Some strong pain medicines (opioids)
• Other medicines that affect the central nervous system

Practical tip: If you take multiple allergy or cold products, check active ingredients carefully to avoid duplicating antihistamines.

Safety Profile & Side Effects

Most people tolerate Astelin well. However, like all medicines, it can cause side effects.

Common side effects

• Bitter taste (often reported after nasal spray use)
• Nasal irritation (mild burning or discomfort)
• Dry nose
• Headache
• Reduced sense of smell (uncommon)
• Mild drowsiness or tired feeling (reported by some people)

Less common but important side effects

• Allergic reactions (e.g., rash, swelling, breathing difficulty) – seek urgent medical help if severe
• Severe dizziness or persistent drowsiness
• Nosebleeds (occasional, especially if the nasal lining is irritated)

When to stop and get medical advice urgently

• Signs of a serious allergic reaction (swelling of face/lips, trouble breathing)
• Very severe dizziness, fainting, or unusual neurological symptoms

Tip: If side effects are bothersome but not severe, speak to a pharmacist or clinician. They may adjust how you use the spray or discuss alternative treatments.

Practical Use Tips (How to Get the Best Results)

Before using

• Gently blow your nose to clear mucus if needed.
• Wash hands before and after use.
• Check that the nozzle is clean and undamaged.

How to use Astelin nasal spray

1. Shake the bottle if the product instructions indicate it.
2. Remove the cap.
3. Prime the pump if required (for example, if it is the first use or it has not been used for a while). Follow the instructions on your pack.
4. Tilt your head slightly forward.
5. Insert the nozzle into one nostril. Keep the other nostril closed gently if needed.
6. Press the trigger to release the dose while breathing in gently through your nose.
7. Repeat for the other nostril if your dose requires it.
8. Try not to sniff hard immediately after spraying, to reduce the chance of the medicine running down the throat.
9. Wipe the nozzle with a clean tissue and replace the cap.

Minimising a bitter taste

• Head position matters: avoid leaning far back.
• Breathing technique: aim for a gentle inhale, not a forceful sniff.
• If taste persists, talk to a pharmacist—sometimes technique adjustments help.

Storage

• Store at room temperature as indicated on the pack.
• Keep out of reach of children.
• Do not use after the expiry date.

Missed Dose, Missed Spray, and Ongoing Management

• Consistency helps: If symptoms are persistent, regular use tends to work better than waiting until symptoms become severe.
• If symptoms flare: Ensure correct technique and adherence to the recommended schedule.
• Consider triggers: Allergen avoidance (e.g., reducing exposure to pollen or dust mites) can improve overall control.

Alternative Options (UK)

Depending on your symptoms and medical history, alternatives may include:

• Intranasal corticosteroids (often first-line for moderate to severe allergic rhinitis). Examples include fluticasone, mometasone, and others.
• Oral antihistamines (non-drowsy options such as cetirizine or loratadine, depending on suitability).
• Other intranasal antihistamines (for example, products containing azelastine-like medicines or combination sprays where appropriate).
• Saline rinses to help clear allergens and reduce nasal irritation.

Which is best? It often depends on symptom pattern (sneezing/itching vs congestion), severity, and whether symptoms occur seasonally or year-round. A pharmacist can help you compare options.
