What Is Becodefence Plus Nasal Spray and How Can It Help You?

 

If you suffer from hay fever or allergic rhinitis, you'll know how disruptive sneezing, a blocked nose, and itchy eyes can be — especially during peak pollen season. Becodefence plus nasal spray offers a drug-free approach to managing these symptoms by creating a physical barrier inside the nasal passages that helps prevent allergens from triggering a reaction in the first place. It's a practical option for anyone who wants to reduce allergen exposure without relying on antihistamines or steroid sprays every day. You can explore a wider range of allergy and hay fever treatments at Cured Pharmacy if you're looking to build a complete management plan.

Hay fever affects around 1 in 5 people in the UK at some point in their lives, according to the NHS. Symptoms are caused by the immune system overreacting to airborne particles such as pollen, dust mites, or pet dander. Becodefence Plus is designed to intercept those particles before they reach the sensitive mucous membranes lining the nose, reducing the likelihood of an allergic response being triggered.

 

How Does Becodefence Plus Nasal Spray Work?

 

The spray works through a physical, rather than pharmacological, mechanism. When applied to the nasal lining, it forms a thin, gel-like protective layer that traps and immobilises airborne allergens. This means pollen, dust, and other particles are less able to penetrate the nasal mucosa and stimulate an immune response.

  • Contains ectoine, a naturally occurring molecule that stabilises cell membranes and helps reduce inflammatory responses at the nasal surface
  • Contains sodium hyaluronate, which hydrates and soothes the nasal lining — particularly useful if your nose feels dry or irritated during allergy season
  • Forms a protective gel barrier on contact with the nasal mucosa, physically blocking allergen penetration
  • Drug-free formulation means no risk of systemic side effects associated with corticosteroids or antihistamines

Because it acts as a barrier rather than suppressing the immune system, it can be used alongside other allergy treatments without concern about drug interactions.

 

Who Should Use Becodefence Plus Nasal Spray?

 

This spray is well suited to a broad range of people. It's particularly useful for those who experience mild to moderate hay fever symptoms and want a non-medicated first line of defence. It's also a sensible choice for people who are cautious about using steroid-based sprays long-term, or who find antihistamine tablets cause drowsiness.

  • Adults and children aged 6 years and over with seasonal allergic rhinitis (hay fever)
  • People with perennial allergic rhinitis triggered by dust mites or pet dander
  • Those who prefer a drug-free, preservative-free nasal spray option
  • Individuals who want to use a barrier spray alongside prescribed allergy medication

It is not intended to replace prescribed treatments for severe allergic rhinitis. If your symptoms are significantly affecting your quality of life, speak to your GP or pharmacist about a more targeted treatment plan.

 

How Does Becodefence Plus Compare to Other Nasal Sprays?

 

Feature Becodefence Plus Nasal Spray Corticosteroid Nasal Spray (e.g. Beclometasone)
Mechanism Physical allergen barrier Anti-inflammatory (pharmacological)
Drug-free Yes No
Suitable for children (6+) Yes Varies by product — check labelling
Drug interactions None known Possible with some systemic medicines
Onset of action Immediate (barrier forms on application) Several days of regular use required

 

Is Becodefence Plus Nasal Spray Suitable for Long-Term Use?

 

Because becodefence plus nasal spray contains no active pharmaceutical ingredients, it does not carry the same concerns around long-term use that are sometimes associated with steroid-based sprays. It can be used throughout the allergy season — or year-round for perennial sufferers — without the risk of nasal mucosal thinning or systemic absorption. That said, if your symptoms persist beyond 30 days or worsen despite using the spray, it's worth speaking to a pharmacist or GP to rule out other causes. You might also find it helpful to browse our ear, nose, and throat range for complementary products.

Store the spray below 25°C, away from direct sunlight, and keep it out of reach of children. Do not use past the expiry date printed on the packaging.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Becodefence Plus Nasal Spray

 

What Is Becodefence Plus Nasal Spray and What Is It Used For?

 

Becodefence Plus Nasal Spray is a drug-free, barrier-forming nasal spray used to help manage the symptoms of allergic rhinitis, including hay fever. It is designed to be applied to the inside of the nostrils before allergen exposure, where it forms a protective layer that physically traps airborne particles — such as pollen, dust mite debris, and pet dander — before they can reach the sensitive nasal mucosa and trigger an allergic response. It is not a medicine in the pharmacological sense; it works mechanically rather than chemically.

It is suitable for adults and children aged 6 and over. It can be used as a standalone measure for mild symptoms or alongside prescribed allergy treatments for more significant allergic rhinitis. The NHS notes that avoiding allergens where possible is an important part of managing hay fever, and a barrier spray can support this approach.

 

What Do You Need to Know Before Using Becodefence Plus Nasal Spray?

 

Although Becodefence Plus is drug-free, there are still important things to consider before using it. Read the following carefully.

Do not use this product if:

  • You are allergic to any of the ingredients listed on the packaging
  • Your child is under 6 years of age
  • You have a nasal injury, recent nasal surgery, or a nasal condition that has not been assessed by a doctor
  • You have a current nasal infection — treat the infection first before using a barrier spray

Warnings and precautions:

  • If symptoms persist for more than 30 days, consult your GP or pharmacist
  • Do not use in place of prescribed medication without speaking to a healthcare professional first
  • Pregnant or breastfeeding women should consult a pharmacist before use, although the drug-free formulation is generally considered low risk
  • Keep out of reach of children; supervise use in children aged 6–12

Known drug interactions:

  • No pharmacological drug interactions are known, as the product contains no active pharmaceutical ingredients
  • It can be used alongside antihistamines, corticosteroid nasal sprays, and eye drops without interaction concerns

 

How Should You Use Becodefence Plus Nasal Spray?

 

Using the spray correctly is important to ensure the barrier forms properly. Follow these steps each time you apply it.

  1. Blow your nose gently to clear the nasal passages before application
  2. Shake the bottle gently before use
  3. Hold the bottle upright and insert the nozzle just inside one nostril
  4. Press the pump once while breathing in gently through the nose
  5. Repeat in the other nostril
  6. Do not blow your nose immediately after application — allow the barrier to form
  7. Apply before going outdoors or entering allergen-rich environments for best effect
Indication Age Group Dose Frequency
Hay fever / allergic rhinitis Adults and children 6+ 1 spray per nostril Up to 3–4 times daily, or before allergen exposure
Perennial allergic rhinitis Adults and children 6+ 1 spray per nostril As needed, before exposure to triggers

If you are also using a medicated nasal spray, apply Becodefence Plus first and wait a few minutes before using the other spray. For those managing multiple allergy symptoms, our allergy and hay fever collection includes a range of complementary options.

 

What Are the Possible Side Effects of Becodefence Plus Nasal Spray?

 

Becodefence Plus is generally very well tolerated. Because it contains no pharmacologically active ingredients, the risk of systemic side effects is negligible. However, as with any product applied to a sensitive mucous membrane, some localised effects are possible.

Common side effects:

  • Mild nasal irritation or tingling immediately after application
  • Temporary sneezing following use
  • Slight sensation of nasal fullness

Less common side effects:

  • Mild nasal dryness (though sodium hyaluronate in the formula is intended to counteract this)
  • Transient watery discharge from the nose

If you experience any unexpected or persistent reaction, stop using the product and speak to your pharmacist. Serious allergic reactions to the ingredients are rare but possible — seek urgent medical attention if you develop swelling of the face, difficulty breathing, or a severe rash.

 

How Should You Store Becodefence Plus Nasal Spray?

 

Correct storage helps maintain the integrity of the barrier-forming formula and ensures the spray remains effective throughout its shelf life.

  • Store below 25°C in a cool, dry place
  • Do not freeze or expose to direct sunlight
  • Keep the cap on when not in use to prevent contamination
  • Keep out of reach and sight of children
  • Do not use after the expiry date printed on the bottle or outer packaging
  • Do not share the spray with others — the nozzle comes into contact with the nasal passages
  • Discard the bottle after the stated number of doses (150 doses) even if liquid appears to remain

If you're building a broader approach to managing seasonal allergies, it may also be worth considering whether eye care products for allergic conjunctivitis could complement your routine — itchy, watery eyes are one of the most common co-occurring symptoms of hay fever.

Frequently Asked Questions

Where can I buy Becodefence Plus Nasal Spray online in the UK?

You can buy Becodefence Plus Nasal Spray directly from Cured Pharmacy, a GPhC-registered online pharmacy offering fast UK delivery. No prescription is required, as it is an over-the-counter product. Simply add it to your basket and check out — it's that straightforward.

How does Becodefence Plus Nasal Spray work in the body?

Becodefence Plus works by forming a thin, gel-like barrier on the nasal mucosa when sprayed into the nostrils. This barrier physically traps airborne allergens — such as pollen and dust — before they can penetrate the nasal lining and trigger an immune response. It does not suppress the immune system; it simply prevents allergens from making contact with the tissue that would react to them.

How do I use Becodefence Plus Nasal Spray step by step?

Start by blowing your nose gently, then shake the bottle. Insert the nozzle just inside one nostril and press the pump once while breathing in gently through the nose, then repeat on the other side. Avoid blowing your nose immediately afterwards so the barrier has time to form properly.

When is the best time to use Becodefence Plus Nasal Spray?

The best time to apply Becodefence Plus is before you go outdoors or enter an environment where allergens are present — for example, before a walk in the park during pollen season or before visiting a home with pets. Applying it proactively means the barrier is already in place when you encounter allergens. You can reapply up to three or four times throughout the day as needed.

What is the correct dose of Becodefence Plus Nasal Spray?

The recommended dose is one spray into each nostril, applied up to three to four times daily or before known allergen exposure. This applies to adults and children aged 6 years and over. Do not exceed the recommended frequency of use without speaking to a pharmacist.

What are the side effects of Becodefence Plus Nasal Spray?

Most people tolerate Becodefence Plus very well, and side effects are uncommon. Some users notice mild nasal irritation or a brief sneezing episode immediately after application, both of which typically resolve within minutes. Because the product contains no pharmacologically active ingredients, systemic side effects are not expected.

Who is eligible to use Becodefence Plus Nasal Spray?

Becodefence Plus is suitable for adults and children aged 6 years and over who experience hay fever or allergic rhinitis triggered by pollen, dust mites, pet dander, or mould spores. It is drug-free, making it a suitable choice for people who prefer to avoid medicated sprays or who want to use it alongside existing allergy treatments. Those with nasal injuries or recent nasal surgery should consult a healthcare professional before use.

Can I use Becodefence Plus Nasal Spray if I am pregnant?

Because Becodefence Plus contains no pharmacologically active ingredients, it is generally considered low risk during pregnancy. However, as with any product used during pregnancy or breastfeeding, it is always sensible to check with your pharmacist or midwife before starting use. The NHS recommends speaking to a healthcare professional about managing hay fever safely during pregnancy.

What happens if I miss a dose of Becodefence Plus Nasal Spray?

Missing an application simply means the protective barrier may not be in place during that period of allergen exposure. There is no pharmacological consequence to missing a dose — just apply the spray as soon as you remember, particularly before going outdoors. You do not need to double up on doses to compensate.

Can I use Becodefence Plus Nasal Spray alongside antihistamines?

Yes — because Becodefence Plus is drug-free and works through a physical mechanism, it has no known interactions with antihistamines, corticosteroid nasal sprays, or other allergy medications. Many people use it as part of a broader allergy management plan that includes antihistamine tablets or other treatments from our allergy and hay fever range. If you are unsure about combining treatments, speak to your pharmacist.

How long can I use Becodefence Plus Nasal Spray for?

Becodefence Plus can be used throughout the allergy season — typically spring and summer for pollen sufferers — or year-round for those with perennial allergic rhinitis caused by dust mites or pet dander. There are no known concerns about long-term use given its drug-free formulation. If symptoms persist beyond 30 days despite regular use, consult your GP or pharmacist to review your management plan.

What are alternatives to Becodefence Plus Nasal Spray?

Alternatives include corticosteroid nasal sprays such as beclometasone dipropionate or fluticasone propionate, which reduce nasal inflammation pharmacologically, as well as antihistamine nasal sprays like azelastine. Other barrier sprays containing cellulose powder or sesame oil are also available. Your pharmacist can help you decide which option best suits your symptom severity and preferences — you can also browse our ear, nose, and throat collection for more options.

Is Becodefence Plus Nasal Spray suitable for children?

Yes, Becodefence Plus is suitable for children aged 6 years and over. Children under 6 should not use this product. For children aged 6 to 12, adult supervision during application is recommended to ensure correct technique and to avoid accidental ingestion or eye contact.

How many doses does a bottle of Becodefence Plus Nasal Spray contain?

Each bottle of Becodefence Plus Nasal Spray contains 150 doses. Based on the recommended usage of one spray per nostril up to four times daily, a single bottle can last several weeks for most users. Discard the bottle after the stated number of doses even if liquid appears to remain, as the dose counter ensures accurate delivery.

What is the latest research on barrier nasal sprays for hay fever?

Research into barrier nasal sprays has grown in recent years, with studies suggesting that physical allergen barriers can meaningfully reduce nasal allergen load and associated symptom scores in people with allergic rhinitis. Ectoine, one of the key ingredients in Becodefence Plus, has been studied for its membrane-stabilising and anti-inflammatory properties at the cellular level. The NHS continues to recommend allergen avoidance as a core strategy in hay fever management, and barrier sprays support this approach in a practical, drug-free way.

How Should You Use Becodefence Plus Nasal Spray?

Using Becodefence Plus correctly ensures the protective barrier forms properly inside the nasal passages. Always read the instructions on the packaging before first use, and follow the steps below each time you apply the spray.

If you are also using a medicated nasal spray such as a corticosteroid, apply Becodefence Plus first and wait a few minutes before using the other product. This ensures neither product interferes with the other's delivery.

What Is the Correct Dose of Becodefence Plus Nasal Spray?

The recommended dose is one spray into each nostril, applied up to three to four times daily or before known allergen exposure. Do not exceed this frequency without guidance from a pharmacist or GP.

When Is the Best Time to Use Becodefence Plus Nasal Spray?

For maximum benefit, apply the spray before you are exposed to allergens rather than after symptoms have already started. If you know you'll be spending time outdoors during high pollen periods, apply it before you leave the house. Pollen counts tend to be highest in the morning and early evening, so timing your application around these windows can make a real difference to how you feel throughout the day.

If you are indoors around pets or in a dusty environment, apply the spray before entering those spaces. Reapply as needed throughout the day, up to the recommended maximum frequency.

How Long Can You Use Becodefence Plus Nasal Spray For?

Becodefence Plus can be used throughout the entire allergy season — typically spring through to early autumn for pollen sufferers — or year-round for those with perennial allergic rhinitis. Because it contains no pharmacologically active ingredients, there are no known concerns about prolonged use, and it does not carry the risks of nasal mucosal thinning sometimes associated with long-term corticosteroid spray use.

If your symptoms have not improved after 30 days of regular use, or if they worsen at any point, speak to your GP or pharmacist to review your treatment plan. A single bottle provides 150 doses, which should last several weeks at the recommended frequency of use.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Becodefence Plus Nasal Spray?

Becodefence Plus Nasal Spray is generally very well tolerated. Because it contains no pharmacologically active ingredients, the risk of systemic side effects is extremely low. Most people use it throughout the allergy season without any problems at all. That said, as with any product applied to the nasal mucosa, some localised effects can occasionally occur.

  • Mild nasal irritation or tingling immediately after application
  • Temporary sneezing following use
  • A brief sensation of nasal fullness or pressure

What Are the Less Common Side Effects of Becodefence Plus Nasal Spray?

Less commonly, some users may notice the following effects. These are typically mild and short-lived, and do not usually require stopping the product.

  • Mild nasal dryness — though the sodium hyaluronate in the formula is specifically included to help hydrate the nasal lining and counteract this
  • Transient watery nasal discharge after application
  • A slight unpleasant taste at the back of the throat if the spray is directed too far back into the nasal passage

What Are the Serious Side Effects of Becodefence Plus Nasal Spray?

Serious reactions to Becodefence Plus are rare. However, as with any product, an allergic reaction to one of the ingredients is possible, even if uncommon. You should seek urgent medical attention if you experience any of the following after using the spray.

  • Swelling of the face, lips, tongue, or throat
  • Difficulty breathing or swallowing
  • A severe or spreading skin rash
  • Dizziness or feeling faint

These symptoms may indicate anaphylaxis, which is a medical emergency. Call 999 immediately if you suspect a severe allergic reaction.

What Should You Do If You Experience Side Effects of Becodefence Plus Nasal Spray?

For mild side effects such as nasal irritation or sneezing, no specific action is usually needed — these effects tend to resolve on their own within a few minutes of application. If irritation persists or becomes bothersome, stop using the product and speak to your pharmacist. They can advise whether to continue, switch to an alternative, or refer you to your GP if needed. Never ignore a side effect that feels unusual or that does not resolve quickly.

Can Becodefence Plus Nasal Spray Interact With Other Medicines?

Because Becodefence Plus contains no pharmacologically active ingredients, no drug interactions are currently known. It can be safely used alongside antihistamines, corticosteroid nasal sprays, decongestants, and eye drops without concern about pharmacological interaction. If you are using a medicated nasal spray at the same time, apply Becodefence Plus first and allow a few minutes before using the other product, to ensure both are delivered effectively to the nasal mucosa.

If you are taking any prescribed medicines or have an underlying health condition, it is always good practice to mention any new products — including non-medicated ones — to your pharmacist or GP.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
