Are Pollenase Hayfever Eye Drops Right for You?

 

If your eyes turn red, itchy, and watery every time the pollen count rises, you are far from alone. Hay fever affects around one in five people in the UK, and for many, the eyes bear the brunt of it. Hayfever eye drops like Pollenase Hayfever Relief 2% w/v Eye Drops offer targeted, fast-acting relief directly where you need it most. Available without a prescription for just £4.49, this 10ml bottle is a practical, affordable option to keep in your bag or medicine cabinet throughout the season. You can browse the full range of allergy and hay fever treatments at Cured Pharmacy if you need additional symptom relief alongside your eye drops.

The active ingredient is sodium cromoglicate 2% w/v — a well-established mast cell stabiliser that has been used in eye care for decades. It works by preventing the release of histamine from mast cells in the conjunctiva, which is the thin membrane covering the white of your eye. Less histamine means less itching, less redness, and fewer of those frustrating watery eyes that make hay fever season so miserable.

 

How Do Pollenase Eye Drops Work in the Eye?

 

Sodium cromoglicate is classified as a mast cell stabiliser. When allergens like pollen land on the surface of your eye, they trigger mast cells to release inflammatory chemicals — histamine being the main culprit. Pollenase works by stabilising those mast cells so they do not release their contents in the first place. Think of it as putting a lock on the door before the alarm goes off, rather than trying to silence it afterwards.

  • Allergen (e.g. pollen) contacts the conjunctival surface
  • Sodium cromoglicate stabilises mast cell membranes
  • Histamine and other inflammatory mediators are not released
  • Itching, redness, and watering are prevented or significantly reduced
  • Regular use throughout the season maintains this protective effect

Because it works preventatively rather than reactively, it is most effective when used consistently — ideally starting before peak pollen season begins.

 

Who Should Use Pollenase Hayfever Relief Eye Drops?

 

These drops are suitable for adults and children aged 6 years and over who experience eye symptoms related to hay fever or seasonal allergic conjunctivitis. They are particularly useful if you find that oral antihistamines alone do not fully control your eye symptoms, or if you prefer a targeted topical treatment rather than a systemic one.

  • Adults and children aged 6 and over with seasonal allergic conjunctivitis
  • People whose primary hay fever symptoms are ocular (itchy, red, watery eyes)
  • Those who want a preventative approach to eye allergy symptoms
  • Patients who cannot tolerate or prefer to avoid oral antihistamines

Do not use these drops if you are allergic to sodium cromoglicate or any other ingredient listed in the product. Always check the full ingredients list before use.

Are Pollenase Eye Drops Safe to Store and Use Long-Term?

 

Pollenase Hayfever Relief 2% w/v Eye Drops should be stored below 25°C, away from direct sunlight, and kept out of the reach and sight of children. Once opened, the bottle must be discarded after 28 days — even if there is solution remaining. This is standard practice for multi-dose eye drop bottles to prevent contamination and infection risk. If you are looking for additional eye care products, Cured Pharmacy stocks a range of options to support your eye health throughout the year.

These drops are intended for seasonal use during the hay fever period. If your symptoms persist beyond what you would expect from seasonal allergies, or if you experience any unusual eye symptoms, speak to your GP or pharmacist. Do not use the drops for longer than recommended without seeking professional advice.

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.

What Is Pollenase Hayfever Relief and What Is It Used For?

 

Pollenase Hayfever Relief 2% w/v Eye Drops contain sodium cromoglicate, a mast cell stabiliser used to treat and prevent the eye symptoms of hay fever and seasonal allergic conjunctivitis. These symptoms include itching, redness, watering, and a gritty or burning sensation in the eyes. The drops work directly on the surface of the eye, making them a targeted option for people whose hay fever symptoms are predominantly ocular. They are available over the counter without a prescription and are suitable for adults and children aged 6 years and over.

 

What Do You Need to Know Before Using Pollenase Eye Drops?

 

Before using these drops, read the following carefully. There are some situations where you should not use them, and others where extra caution is needed.

Do not use Pollenase Eye Drops if you:

  • Are allergic to sodium cromoglicate or any other ingredient in the formulation
  • Are wearing soft contact lenses at the time of instillation
  • Are under 6 years of age

Take extra care and speak to your pharmacist or GP if you:

  • Have any existing eye condition or infection
  • Are pregnant or breastfeeding — seek medical advice before use
  • Experience worsening symptoms or no improvement after a few days of use
  • Have previously had an allergic reaction to any eye drop preparation

Drug interactions:

  • No clinically significant interactions have been reported for topical sodium cromoglicate eye drops
  • If you are using other eye drops or eye ointments, leave at least 5 minutes between applications
  • Always tell your pharmacist about all medicines you are taking, including herbal remedies

 

How Should You Use Pollenase Hayfever Relief Eye Drops?

 

Always use these drops exactly as directed on the label or as advised by your pharmacist. Do not use more than the recommended dose. If you wear soft contact lenses, remove them before applying the drops and wait at least 30 minutes before reinserting.

  1. Wash your hands thoroughly before handling the bottle
  2. Tilt your head back slightly and look upward
  3. Gently pull down your lower eyelid to create a small pocket
  4. Hold the dropper tip close to your eye without touching it
  5. Squeeze one to two drops into the pocket formed by the lower eyelid
  6. Close your eye gently and blink once or twice to spread the drops
  7. Repeat in the other eye if both are affected
  8. Replace the cap immediately after use
Indication Age Group Dose Frequency
Seasonal allergic conjunctivitis / hay fever Adults and children aged 6+ 1–2 drops per affected eye Four times daily
Children under 6 Under 6 years Not recommended — seek medical advice

 

What Are the Possible Side Effects of Pollenase Eye Drops?

 

Like all medicines, Pollenase Eye Drops can cause side effects, although not everyone experiences them. Most side effects are mild and temporary. If you experience anything severe or unexpected, stop using the drops and contact your pharmacist or GP.

Common side effects (may affect up to 1 in 10 people):

  • Transient stinging or burning sensation immediately after instillation
  • Temporary blurred vision — do not drive until your vision is clear
  • Mild eye irritation or discomfort

Less common side effects (may affect fewer than 1 in 100 people):

  • Watering of the eyes immediately after use
  • Redness of the eye (transient)
  • Hypersensitivity reactions — stop use immediately if you notice swelling, severe redness, or rash around the eye

If you experience a severe allergic reaction — including swelling of the face, lips, or throat, or difficulty breathing — seek emergency medical attention immediately. This is rare but serious. You can find further information about managing allergy symptoms through our allergy and hay fever section.

 

How Should You Store Pollenase Hayfever Relief Eye Drops?

 

Correct storage keeps the drops sterile and effective throughout the season. Follow these instructions carefully:

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep the bottle tightly closed when not in use
  • Discard the bottle 28 days after first opening, even if solution remains
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the label
  • Do not freeze

Writing the date you opened the bottle on the label is a simple habit that helps you track the 28-day discard window. If you are managing multiple allergy treatments this season, our eye care collection includes a range of products to support your eye health alongside your hay fever management plan.

Frequently Asked Questions

Where can I buy Pollenase Hayfever Relief Eye Drops online in the UK?

You can buy Pollenase Hayfever Relief 2% w/v Eye Drops online from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £4.49. They are available without a prescription and can be ordered alongside other allergy and hay fever treatments for convenient delivery to your door. No appointment or prescription is needed.

How do Pollenase Eye Drops work in the eye?

Pollenase Eye Drops contain sodium cromoglicate 2% w/v, which works as a mast cell stabiliser. When pollen or another allergen contacts the surface of your eye, it would normally trigger mast cells to release histamine — the chemical responsible for itching, redness, and watering. Sodium cromoglicate prevents that release, stopping the allergic reaction before it takes hold. This is why regular, consistent use gives the best results.

How do I use Pollenase Eye Drops step by step?

Wash your hands first, then tilt your head back and gently pull down your lower eyelid. Squeeze one to two drops into the pocket formed by the lower lid, close your eye gently, and blink once or twice. Avoid touching the dropper tip to your eye or any surface to keep the solution sterile, and replace the cap immediately after use.

What is the correct dose of Pollenase Eye Drops for adults?

The recommended dose for adults is one to two drops in each affected eye, four times daily. Space the doses evenly throughout the day for consistent protection. Do not exceed this dose without speaking to your pharmacist or GP first.

Can children use Pollenase Hayfever Relief Eye Drops?

Yes — Pollenase Eye Drops are suitable for children aged 6 years and over, using the same dose as adults: one to two drops in each affected eye, four times daily. They are not recommended for children under 6 years of age. If your child is under 6 and experiencing eye symptoms, speak to your GP for appropriate advice.

Can I use Pollenase Eye Drops with contact lenses?

No — you must remove soft contact lenses before instilling Pollenase Eye Drops. Wait at least 30 minutes after applying the drops before reinserting your lenses. Hard (rigid gas permeable) lenses should also be removed; check with your optician or pharmacist if you are unsure about your specific lens type.

How long does it take for Pollenase Eye Drops to start working?

Because sodium cromoglicate is a preventative mast cell stabiliser rather than an immediate-acting antihistamine, it typically takes a few days of regular use before you notice the full benefit. Starting the drops a week or two before the hay fever season begins — or before you expect to be exposed to your trigger allergen — gives the best results. Consistent daily use is key.

What are the side effects of Pollenase Eye Drops?

The most commonly reported side effects are a brief stinging or burning sensation immediately after instillation and temporary blurred vision. These are usually mild and pass within a minute or two. Less commonly, some people experience transient redness or watering of the eye. If you notice any signs of a hypersensitivity reaction — such as swelling around the eye or a rash — stop using the drops and seek medical advice promptly.

What happens if I miss a dose of Pollenase Eye Drops?

If you miss a dose, simply apply the drops as soon as you remember — unless it is nearly time for your next scheduled dose, in which case skip the missed one and carry on as normal. Do not double up doses to make up for a missed one. Consistent use throughout the day gives the most reliable protection against eye allergy symptoms.

How long can I use Pollenase Eye Drops for?

Pollenase Eye Drops are intended for use during the hay fever season, which in the UK typically runs from late March through to September depending on which pollens trigger your symptoms. Each bottle should be discarded 28 days after opening regardless of how much solution remains. If your symptoms persist outside of the typical season, speak to your GP as this may indicate a perennial (year-round) allergy requiring further assessment.

Are Pollenase Eye Drops safe to use during pregnancy?

If you are pregnant or breastfeeding, you should seek advice from your GP or pharmacist before using Pollenase Eye Drops. While topical sodium cromoglicate has limited systemic absorption, it is always best to get professional guidance before using any medicine during pregnancy. Your doctor can help you weigh up the benefits and any potential risks.

What are the alternatives to Pollenase Eye Drops for hay fever eyes?

Alternatives include other sodium cromoglicate eye drops (such as Opticrom), antihistamine eye drops containing azelastine or ketotifen, and oral antihistamines for broader symptom control. You can explore the full range of options in our eye care collection. Your pharmacist can help you decide which approach suits your symptom pattern best.

Do Pollenase Eye Drops treat the cause of hay fever or just the symptoms?

Pollenase Eye Drops treat the symptoms of hay fever — specifically the eye symptoms caused by an allergic reaction to pollen. They do not desensitise you to pollen or cure the underlying allergy. For long-term management of hay fever, speak to your GP about options such as allergen immunotherapy, which aims to reduce sensitivity over time.

Can I use Pollenase Eye Drops alongside oral antihistamines?

Yes — using hayfever eye drops alongside an oral antihistamine is a common and generally safe approach for people with both nasal and eye symptoms. No clinically significant interactions have been reported between topical sodium cromoglicate and oral antihistamines. Always let your pharmacist know all the medicines you are taking so they can check for any potential issues.

What is the latest research on sodium cromoglicate eye drops for hay fever?

Sodium cromoglicate has been used in clinical practice for allergic conjunctivitis for several decades and remains a recommended first-line option in UK clinical guidelines for seasonal eye allergy. It has a well-established safety profile, particularly in children and those who prefer to avoid systemic antihistamines. Current NHS guidance continues to support its use as an effective preventative treatment for hay fever eye symptoms.

How Should You Use Pollenase Hayfever Relief Eye Drops?

Using eye drops correctly makes a real difference to how well they work. Before you start, wash your hands thoroughly with soap and water. If you wear soft contact lenses, remove them before applying the drops and wait at least 30 minutes before putting them back in.

Follow these steps each time you use the drops:

What Is the Correct Dose of Pollenase Hayfever Relief Eye Drops?

Always follow the dosage instructions on the product label or as directed by your pharmacist. The table below summarises the recommended doses by age group and indication.

Do not use more drops than recommended — using extra drops will not improve the effect and may cause unnecessary irritation.

When Is the Best Time to Use Pollenase Hayfever Relief Eye Drops?

Because sodium cromoglicate works preventatively, timing matters. Ideally, you should start using the drops a week or two before you expect your hay fever season to begin — this gives the medicine time to build its protective effect before pollen levels peak. During the season, space your four daily doses as evenly as possible throughout the day, for example morning, midday, late afternoon, and evening.

If you know you are going to be outdoors in a high-pollen environment, applying your drops beforehand rather than waiting for symptoms to appear will give you better protection. Avoid applying the drops immediately before driving, as temporary blurred vision can occur after instillation.

How Long Can You Use Pollenase Hayfever Relief Eye Drops For?

These drops are designed for use throughout the hay fever season, which in the UK typically runs from late March to September, depending on which pollens affect you. Each bottle must be discarded 28 days after first opening, even if solution remains, to prevent the risk of contamination and eye infection.

If your symptoms continue beyond the expected seasonal period, or if you find the drops are not providing adequate relief after several days of consistent use, speak to your GP or pharmacist. They can assess whether a different treatment approach or further investigation is needed.

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

What Are the Most Common Side Effects of Pollenase Eye Drops?

Most people who use Pollenase Hayfever Relief 2% w/v Eye Drops tolerate them well. The most frequently reported side effects are localised to the eye and are generally mild and short-lived. They tend to occur immediately after instillation and resolve within a minute or two.

  • Transient stinging or burning sensation in the eye immediately after applying the drops
  • Temporary blurred vision — this usually clears within a few minutes
  • Mild eye irritation or discomfort
  • Increased watering of the eye immediately after use

What Are the Less Common Side Effects of Pollenase Eye Drops?

Less commonly, some people may experience additional reactions. These are not typical but are worth being aware of, particularly if you have sensitive eyes or a history of eye conditions.

  • Transient redness of the conjunctiva (the white of the eye)
  • A gritty or foreign body sensation in the eye
  • Eyelid irritation or mild swelling around the eye
  • Dry eye sensation between doses

What Are the Serious Side Effects of Pollenase Eye Drops?

Serious side effects are rare with topical sodium cromoglicate, but they can occur. A hypersensitivity (allergic) reaction to the drops themselves is uncommon but possible. If you notice any of the following, stop using the drops immediately and seek urgent medical attention:

  • Significant swelling of the eyelids, face, lips, or throat
  • Severe redness or pain in the eye that does not settle quickly
  • Skin rash or hives around the eye area
  • Difficulty breathing — this requires emergency medical attention (call 999)

If your eye symptoms worsen rather than improve after a few days of use, this may indicate an eye infection or a different underlying condition. Do not continue using the drops without seeking professional advice in this situation.

What Should You Do If You Experience Side Effects?

For mild side effects such as brief stinging or temporary blurred vision, no specific action is needed — simply wait for the sensation to pass. Avoid driving or operating machinery until your vision has fully cleared after applying the drops. If the stinging is particularly uncomfortable, try storing the bottle in the fridge (but not freezing it) as cooler drops can sometimes feel more soothing.

For any side effect that concerns you, or that does not resolve quickly, contact your pharmacist or GP. They can advise whether you should continue using the drops, switch to an alternative, or seek further assessment. Always report serious or unexpected reactions to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Pollenase Eye Drops Interact With Other Medicines?

No clinically significant drug interactions have been reported for topical sodium cromoglicate eye drops. Because the drops are applied directly to the eye surface and systemic absorption is minimal, the risk of interactions with oral medicines is very low. However, if you are using other eye drops or eye ointments at the same time, leave a gap of at least 5 minutes between applications to prevent one product washing out the other. Always inform your pharmacist of all medicines you are taking, including over-the-counter products and herbal remedies.

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