Are Hay Fever Eye Drops the Answer to Itchy, Watery Eyes?

 

If your eyes turn red, itchy, and streaming the moment pollen season arrives, you are far from alone. Allergic conjunctivitis — the eye component of hay fever — affects millions of people across the UK every spring and summer. Hay fever eye drops containing sodium cromoglicate are one of the most widely recommended over-the-counter options for managing these symptoms, and Murine Hay Fever Relief Eye Drops deliver exactly that in a convenient triple pack. Each pack contains three 10ml bottles, giving you a full season's supply without the hassle of repeated purchases. 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.

Hay fever, or seasonal allergic rhinitis, is triggered by airborne pollen from grasses, trees, and weeds. When pollen lands on the surface of the eye, it triggers an immune response that causes the characteristic itching, redness, and watering that make the season so miserable for sufferers. The NHS notes that hay fever is one of the most common allergic conditions in the UK, affecting around one in five people at some point in their lives.

 

How Do Murine Hay Fever Relief Eye Drops Work?

 

The active ingredient in these drops is sodium cromoglicate 2%. This belongs to a class of medicines called mast cell stabilisers. Here is how it works:

  • Pollen or another allergen contacts the surface of the eye.
  • Mast cells in the conjunctiva would normally release histamine and other inflammatory mediators in response.
  • Sodium cromoglicate stabilises the mast cell membrane, preventing this release from occurring.
  • Without histamine release, the allergic cascade — itching, redness, swelling, watering — is significantly reduced or prevented altogether.

Because sodium cromoglicate works by prevention rather than by reversing an existing reaction, it is most effective when used regularly from the start of the pollen season, even before symptoms appear. Think of it as building a barrier rather than fighting a fire once it has already started.

 

Who Should Use Murine Hay Fever Relief Eye Drops?

 

These drops are suitable for a broad range of patients. They are designed for anyone who experiences eye symptoms as part of their seasonal allergic response. Specifically, they may be appropriate if you:

  • Are an adult or child aged 6 years or over suffering from hay fever-related eye symptoms.
  • Experience itching, redness, watering, or a gritty sensation in the eyes during pollen season.
  • Prefer a preservative-free or low-irritant topical option (check the PIL for the specific formulation details).
  • Want a non-drowsy eye-specific treatment to complement oral antihistamines or nasal sprays.

They are not suitable for children under 6 years without medical supervision, and you should not use them if you have a known hypersensitivity to sodium cromoglicate or any other ingredient listed in the patient information leaflet.

 

How Do Murine Hay Fever Eye Drops Compare to Other Options?

 

Feature Murine Hay Fever Relief Eye Drops Oral Antihistamine Tablets
Targeted action Directly at the eye surface Systemic — whole body
Onset of effect Localised relief within minutes 30–60 minutes for systemic effect
Drowsiness risk None (topical only) Possible with older antihistamines
Suitable age 6 years and over Varies by product

 

Are Murine Hay Fever Relief Eye Drops Safe to Store and Use Long-Term?

 

Storage is straightforward. Keep the bottles below 25°C, away from direct sunlight, and out of the reach of children. Crucially, each bottle must be discarded 28 days after first opening — even if solution remains — to reduce the risk of contamination and eye infection. The triple-pack format is particularly practical here, as it means you always have a fresh, in-date bottle to hand throughout the season. If you are also managing other seasonal symptoms, our eye care collection includes a range of complementary products to support your eye health year-round.

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 Are Murine Hay Fever Relief Eye Drops and What Are They Used For?

 

Murine Hay Fever Relief Eye Drops are a topical ophthalmic medicine containing sodium cromoglicate 2% as the active ingredient. They are used to relieve and prevent the eye symptoms associated with hay fever and seasonal allergic conjunctivitis — specifically itching, redness, watering, and a gritty or burning sensation in the eyes. Sodium cromoglicate is a well-established mast cell stabiliser that has been used in eye drops for allergic conditions for decades. These drops are available over the counter and do not require a prescription.

 

What Do You Need to Know Before Using Murine Hay Fever Relief Eye Drops?

 

Before using these drops, read the following contraindications and warnings carefully:

  • Do not use if you are allergic to sodium cromoglicate or any other ingredient in the formulation.
  • Do not use in children under 6 years of age without medical advice.
  • Do not instil drops whilst wearing soft (hydrophilic) contact lenses — remove lenses first and wait at least 30 minutes before reinserting.
  • If you wear hard contact lenses, seek advice from your optician before use.
  • Do not use if the solution has changed colour or become cloudy.
  • Consult your GP or pharmacist if you have any existing eye conditions, are pregnant, or are breastfeeding.
  • If symptoms do not improve within a few days of regular use, seek medical advice.

Regarding drug interactions, topical sodium cromoglicate has no clinically significant known interactions with other medicines. However, if you are using other eye drops or eye ointments, allow at least five minutes between applications and apply ointments last. Always tell your pharmacist about all medicines you are currently taking.

  • No significant systemic drug interactions are currently documented for topical sodium cromoglicate.
  • If using multiple eye preparations, space applications by at least 5 minutes.

 

How Should You Use Murine Hay Fever Relief Eye Drops?

 

Follow these steps carefully each time you use the drops:

  1. Wash your hands thoroughly with soap and water before handling the bottle.
  2. If wearing soft contact lenses, remove them before applying the drops.
  3. Tilt your head back slightly and look upward.
  4. Gently pull down your lower eyelid to create a small pocket.
  5. Hold the bottle above the eye and instil one to two drops into the pocket formed by the lower eyelid.
  6. Release the eyelid and blink gently to spread the solution across the eye surface.
  7. Repeat in the other eye if required.
  8. Replace the cap immediately after use. Do not touch the dropper tip to your eye, fingers, or any surface.
Indication Age Group Dose Frequency
Allergic conjunctivitis / hay fever eyes Adults and children 6+ 1–2 drops per affected eye 4 times daily
Allergic conjunctivitis / hay fever eyes Under 6 years Not recommended without medical advice

For best results, use the drops regularly throughout the pollen season, even on days when your symptoms feel mild. Sodium cromoglicate works preventatively, so consistent use is key. If you are also managing nasal hay fever symptoms, you may find it helpful to explore our ear, nose, and throat range for complementary treatments.

 

What Are the Possible Side Effects of Murine Hay Fever Relief Eye Drops?

 

Like all medicines, Murine Hay Fever Relief Eye Drops can cause side effects, although not everyone experiences them. Most side effects are mild and localised to the eye.

Common side effects:

  • Transient stinging or burning sensation immediately after instillation
  • Temporary blurred vision (usually clears within a few minutes)
  • Mild eye irritation

Less common side effects:

  • Watering of the eyes immediately after use
  • Redness of the eye (usually short-lived)
  • Sensitivity to light (photophobia) — rare

Stop using the drops and seek medical advice promptly if you experience severe eye pain, significant worsening of redness, swelling around the eye, or any signs of an allergic reaction such as rash, swelling of the face, or difficulty breathing. These reactions are rare but require immediate attention.

 

How Should You Store Murine Hay Fever Relief Eye Drops?

 

  • Store below 25°C in a cool, dry place away from direct sunlight and heat.
  • Keep all bottles out of the reach and sight of children.
  • Do not store in the bathroom or near a sink where moisture and heat can affect the product.
  • Discard each bottle 28 days after first opening, even if solution remains — write the opening date on the bottle label.
  • Do not use after the expiry date printed on the carton or bottle.
  • Do not freeze.
  • Do not use if the solution appears discoloured or cloudy.

The triple-pack format means you can open one bottle at a time and keep the others sealed until needed, maximising freshness across the season. If you are looking for additional support during allergy season, our allergy and hay fever collection has a wide range of options to help manage symptoms from head to toe.

Frequently Asked Questions

Where can I buy Murine Hay Fever Relief Eye Drops online in the UK?

You can buy Murine Hay Fever Relief Eye Drops directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. No prescription is needed as this is an over-the-counter medicine. The 3 x 10ml triple pack is available at £15.99 and offers excellent value for the full hay fever season. You can also browse our wider allergy and hay fever range for complementary products.

How do Murine Hay Fever Relief Eye Drops work in the body?

These drops contain sodium cromoglicate 2%, a mast cell stabiliser that works by preventing mast cells in the conjunctiva from releasing histamine when they encounter an allergen such as pollen. Without histamine release, the allergic reaction — itching, redness, watering — is significantly reduced or prevented. Because the medicine acts locally on the eye surface, it does not cause the systemic effects (such as drowsiness) sometimes associated with oral antihistamines.

How do I use Murine Hay Fever Relief Eye Drops step by step?

Wash your hands before use, remove any soft contact lenses, and tilt your head back. Gently pull down your lower eyelid and instil one to two drops into the pocket formed. Blink gently to spread the solution, replace the cap immediately, and avoid touching the dropper tip to any surface. Repeat in the other eye if needed, and wait at least 30 minutes before reinserting soft contact lenses.

How many times a day should I use Murine Hay Fever Relief Eye Drops?

The recommended dose for adults and children aged 6 and over is one to two drops in each affected eye, four times daily. Try to space doses evenly throughout the day — for example, morning, midday, late afternoon, and evening. Do not use more frequently than recommended without speaking to a pharmacist or GP first.

What are the side effects of Murine Hay Fever Relief Eye Drops?

The most commonly reported side effects are a brief stinging or burning sensation immediately after instillation and temporary blurred vision, both of which usually resolve within a few minutes. Less commonly, you may notice mild eye watering or transient redness after applying the drops. If you experience persistent pain, significant worsening of symptoms, or any signs of an allergic reaction, stop use and contact your pharmacist or GP promptly.

Can children use Murine Hay Fever Relief Eye Drops?

Yes — these drops are suitable for adults and children aged 6 years and over. They should not be used in children under 6 years of age without specific medical advice from a GP or paediatrician. Always supervise younger children during instillation to ensure correct technique and to avoid accidental contact with the dropper tip.

Can I wear contact lenses while using Murine Hay Fever Relief Eye Drops?

You must remove soft (hydrophilic) contact lenses before instilling these drops and wait at least 30 minutes before reinserting them. Hard contact lenses may generally be worn during treatment, but it is advisable to check with your optician. If you are unsure about your specific lens type, remove them as a precaution before applying the drops.

How long can I use Murine Hay Fever Relief Eye Drops for?

These drops can be used throughout the hay fever season, which typically runs from late March through to September in the UK, depending on which pollens trigger your symptoms. Each bottle must be discarded 28 days after opening regardless of how much solution remains, so the triple-pack format is ideal for seasonal use. If your symptoms persist outside of the typical pollen season, speak to your GP as this may indicate a different underlying cause.

What happens if I miss a dose of Murine Hay Fever Relief Eye Drops?

If you miss a scheduled dose, simply apply the drops as soon as you remember — unless it is nearly time for your next dose, in which case skip the missed one and continue as normal. Do not double up doses to compensate for a missed application. Consistent, regular use gives the best preventative effect, so try to build the drops into your daily routine.

Are Murine Hay Fever Relief Eye Drops safe to use during pregnancy?

If you are pregnant or breastfeeding, you should consult your GP or pharmacist before using these drops, even though topical sodium cromoglicate has very limited systemic absorption. Your healthcare professional can weigh up the potential benefits against any theoretical risks and advise on the most appropriate treatment for your situation. Do not self-medicate during pregnancy without seeking advice first.

What are the alternatives to Murine Hay Fever Relief Eye Drops?

Alternatives include other topical antihistamine eye drops such as azelastine or olopatadine, which may offer faster symptom relief but work differently to sodium cromoglicate. Oral antihistamines (e.g. cetirizine, loratadine) address systemic hay fever symptoms including eye symptoms, though they are less targeted. You can explore the full range of options in our eye care collection to find the most suitable product for your needs.

Do Murine Hay Fever Relief Eye Drops work immediately?

Sodium cromoglicate works primarily as a preventative medicine rather than a fast-acting rescue treatment — it stabilises mast cells before they release histamine, so it is most effective when used regularly from the start of the pollen season. You may notice some soothing relief shortly after instillation, but the full preventative benefit builds up with consistent daily use over several days. If you need immediate relief during an acute episode, speak to your pharmacist about whether a topical antihistamine eye drop might be more appropriate as a short-term option.

How should I store Murine Hay Fever Relief Eye Drops?

Store the bottles below 25°C in a cool, dry place away from direct sunlight, and keep them out of the reach of children. Do not store in the bathroom where heat and humidity can affect the solution. Each bottle must be discarded 28 days after first opening — write the date on the label when you first open it to keep track.

Can I use Murine Hay Fever Relief Eye Drops with other hay fever medicines?

Yes — these drops can generally be used alongside oral antihistamines or nasal corticosteroid sprays as part of a broader hay fever management plan. No clinically significant interactions between topical sodium cromoglicate and other commonly used hay fever medicines have been documented. However, if you are using other eye drops at the same time, leave at least five minutes between applications and always tell your pharmacist about all medicines you are taking.

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

Sodium cromoglicate has been used in ophthalmic preparations for allergic conjunctivitis for several decades and remains a well-supported first-line option in UK clinical guidelines. Current evidence confirms its efficacy as a mast cell stabiliser for seasonal allergic eye symptoms, with a well-established safety profile and minimal systemic absorption. While newer antihistamine eye drops may offer faster onset, sodium cromoglicate continues to be recommended for regular preventative use throughout the allergy season.

How Should You Use Murine Hay Fever Relief Eye Drops?

Using these drops correctly makes a real difference to how well they work. Always wash your hands thoroughly before handling the bottle, and remove soft contact lenses before applying the drops. Follow these steps each time:

If you are using other eye drops at the same time, leave at least five minutes between each preparation. Apply any eye ointments last.

What Is the Correct Dose of Murine Hay Fever Relief Eye Drops?

The dose is the same for adults and children aged 6 and over. Always use the lowest number of drops that controls your symptoms effectively, and do not exceed the recommended daily frequency. The table below summarises the dosing guidance:

Space your four daily doses as evenly as possible throughout the day — for example, on waking, at midday, in the late afternoon, and before bed. This helps maintain a consistent level of protection across the day.

When Is the Best Time to Use Murine Hay Fever Relief Eye Drops?

Because sodium cromoglicate works preventatively by stabilising mast cells before they release histamine, the best approach is to start using the drops at the beginning of the pollen season — even before your symptoms appear. If you know your hay fever typically begins in late March or April, start the drops a few days before you expect symptoms to arrive. Using them consistently throughout the season, rather than only on high-pollen days, gives you the most reliable protection. Morning use is particularly important as pollen counts tend to peak in the morning and early afternoon on warm, dry days.

What Are the Most Common Side Effects of Murine Hay Fever Relief Eye Drops?

Most people tolerate Murine Hay Fever Relief Eye Drops well, and side effects are generally mild and short-lived. The most frequently reported effects occur immediately after instillation and resolve on their own within a few minutes.

  • Transient stinging or burning sensation in the eye immediately after applying the drops
  • Temporary blurred vision lasting a few minutes after instillation
  • Mild eye irritation or discomfort
  • Brief watering of the eyes after application

What Are the Less Common Side Effects of Murine Hay Fever Relief Eye Drops?

Less commonly, some people may notice additional effects that are still generally mild. These are not experienced by the majority of users but are worth being aware of before you start treatment.

  • Transient redness of the eye following instillation
  • Sensitivity to light (photophobia) — this is rare
  • A feeling of grittiness or foreign body sensation in the eye
  • Eyelid irritation or puffiness in isolated cases

What Are the Serious Side Effects of Murine Hay Fever Relief Eye Drops?

Serious side effects with topical sodium cromoglicate are rare, but you should be aware of the signs that require prompt medical attention. Stop using the drops immediately and seek medical advice if you experience any of the following:

  • Severe or persistent eye pain that does not resolve quickly after instillation
  • Significant worsening of redness, swelling, or discharge from the eye
  • Sudden change in vision or visual disturbance that does not clear
  • Signs of a systemic allergic reaction — rash, swelling of the face or throat, difficulty breathing, or dizziness

Although a systemic allergic reaction to topically applied sodium cromoglicate is extremely rare given its minimal absorption, it cannot be entirely excluded. If you experience any of the above, seek emergency medical attention immediately.

What Should You Do If You Experience Side Effects of Murine Hay Fever Relief Eye Drops?

For mild, transient effects such as brief stinging or temporary blurred vision, no specific action is needed — simply wait a few minutes for the sensation to pass. Avoid rubbing your eyes, as this can worsen irritation and potentially introduce bacteria. If you find the stinging particularly uncomfortable, try storing the bottle in the fridge (not the freezer) before use, as cooler drops can sometimes feel more soothing. For any side effect that persists, worsens, or concerns you, stop using the drops and speak to your pharmacist or GP. You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.
