What Is Optrex Multi Action Eye Wash?

 

Your eyes put up with a lot every single day — screens, air conditioning, dust, pollen, and late nights. When they start to feel gritty, sore, or just plain tired, a gentle eye wash can make a real difference. Optrex Multi Action Eye Wash 300ml is an over-the-counter ocular rinse designed to cleanse, soothe, and refresh eyes that have been exposed to everyday irritants. It has been a trusted name in UK eye care for decades, and you can find it alongside other eye care products at Cured Pharmacy.

The 300ml bottle comes with a reusable eye bath, making it straightforward to use at home without any specialist equipment. It is suitable for adults and children aged 12 and over, and because it is available without a prescription, it is one of the most accessible options for managing mild to moderate eye irritation quickly.

 

How Does Optrex Multi Action Eye Wash Work?

 

The active ingredient in this product is witch hazel (Hamamelis virginiana) at a concentration of 13% v/v. Witch hazel is a plant-derived extract with well-established mild astringent and soothing properties. When used as an ocular rinse, it works by physically flushing away surface debris, dust particles, and other irritants from the eye. At the same time, its astringent action helps to calm the conjunctival tissue, reducing the sensation of soreness and discomfort.

  • Physically rinses away dust, smoke particles, chlorine, and pollen from the eye surface
  • Witch hazel's mild astringent properties help soothe inflamed or irritated conjunctival tissue
  • The buffered, isotonic formulation is gentle on the delicate ocular surface
  • Refreshes tired eyes by restoring a clean, comfortable feeling to the eye surface

 

Who Should Use Optrex Multi Action Eye Wash?

 

This product is intended for people who experience mild, non-infectious eye irritation caused by environmental factors. It is not a treatment for eye infections, conjunctivitis, or any diagnosed eye condition — if you suspect an infection, you should speak to your GP or pharmacist promptly. That said, it suits a wide range of everyday situations.

  • Adults and children aged 12 and over with sore or tired eyes
  • People exposed to dusty, smoky, or polluted environments
  • Those whose eyes feel irritated after swimming in chlorinated pools
  • Anyone experiencing mild eye discomfort linked to hay fever or airborne allergens

If your symptoms are related to seasonal allergies, it is worth exploring our allergy and hay fever range alongside this product, as a combined approach may offer more complete relief.

 

How Does Optrex Multi Action Eye Wash Compare to Eye Drops?

Active ingredient Witch hazel 13% v/v Typically hyaluronic acid or carbomer
Best suited for Irritation from dust, smoke, chlorine, pollen Dry eye syndrome, prolonged screen use
Contact lens use Remove lenses before use Some formulations are lens-compatible

 

Is Optrex Multi Action Eye Wash Suitable for Sensitive Eyes?

 

Most people with sensitive eyes tolerate this eye wash well, but it is always sensible to check the full ingredient list before use if you have a known sensitivity to plant-derived extracts. The formulation is buffered to be gentle on the ocular surface, and the witch hazel concentration is low enough to minimise the risk of irritation in most users. If you experience any persistent discomfort after use, discontinue and seek advice from a pharmacist or GP.

Store the product below 25°C, away from direct sunlight, and discard any remaining solution 28 days after first opening. Do not use if the tamper-evident seal is broken before first use.

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 Optrex Multi Action Eye Wash 300ml

 

What Is Optrex Multi Action Eye Wash and What Is It Used For?

 

Optrex Multi Action Eye Wash 300ml is an over-the-counter ocular rinse used to cleanse and soothe eyes that feel sore, tired, or irritated. It contains witch hazel (Hamamelis virginiana) 13% v/v as its active ingredient, which provides a gentle astringent and soothing effect on the eye surface. The NHS advises that most cases of eye irritation caused by environmental factors — such as dust, smoke, or chlorine — can be managed at home with appropriate cleansing measures. This product is designed precisely for those situations.

It is not intended to treat eye infections, conjunctivitis, or any diagnosed ocular condition. If your eyes are producing a discharge, are significantly red, or your vision is affected, you should seek advice from a pharmacist or GP rather than relying on an eye wash alone.

 

What Do You Need to Know Before Using Optrex Multi Action Eye Wash?

 

Before using this product, read the following carefully. There are certain situations where you should not use this eye wash, and others where extra caution is needed.

Do not use this product if you:

  • Have a foreign body embedded in your eye — seek urgent medical attention instead
  • Have had recent eye surgery without first consulting your surgeon
  • Are under 12 years of age

  • Wear contact lenses — always remove lenses before use and wait at least 15 minutes before reinserting
  • Are pregnant or breastfeeding
  • Have a diagnosed eye condition such as glaucoma or dry eye syndrome
  • Experience worsening symptoms or no improvement after 48 hours of use

Known drug interactions:

  • No clinically significant drug interactions are currently known for topical witch hazel eye wash
  • If you use other eye drops or ointments, wait at least 5 minutes between applications

  3. Tilt your head forward and place the eye bath firmly over your eye, creating a seal
  4. Tilt your head back slowly, keeping the eye bath in place
  5. Open your eye and blink several times to allow the solution to rinse the eye surface
  6. Tilt your head forward again and remove the eye bath

The product works by physically flushing irritants — such as dust, pollen, smoke, and chlorine — from the surface of the eye. Its active ingredient, witch hazel 13% v/v, provides a mild astringent effect that helps soothe the conjunctival tissue. Together, these actions leave the eye feeling cleaner and more comfortable.

How do I use Optrex Multi Action Eye Wash step by step?

Fill the included eye bath to the halfway mark, tilt your head forward, and place the bath firmly over your eye. Tilt your head back and blink several times to allow the solution to rinse the eye, then tilt forward again and remove the bath. Always discard the used solution and use fresh liquid for the second eye.

How many times a day can I use this eye wash?

You can use Optrex Multi Action Eye Wash up to three times daily. If your symptoms have not improved after 48 hours of regular use, it is advisable to speak to your pharmacist or GP. Overuse beyond the recommended frequency is not recommended without professional guidance.

Can I use Optrex Multi Action Eye Wash with contact lenses in?

No — you must remove your contact lenses before using this eye wash. Wait at least 15 minutes after use before reinserting your lenses. Using the product with lenses in place could cause discomfort or damage to the lens material.

What are the side effects of Optrex Multi Action Eye Wash?

The most commonly reported side effects include a temporary stinging or burning sensation and brief blurred vision immediately after use. These effects are usually short-lived and resolve on their own within a few minutes. If you experience persistent redness, swelling, or increased irritation, stop using the product and seek pharmacist advice.

Is Optrex Multi Action Eye Wash safe to use during pregnancy?

There is no specific evidence of harm from topical witch hazel eye wash during pregnancy, but as with any medicine, you should consult your GP or pharmacist before use if you are pregnant or breastfeeding. They can help you weigh up the benefits and any potential risks for your individual situation.

Is this eye wash suitable for children?

Optrex Multi Action Eye Wash is suitable for adults and children aged 12 and over. It should not be used in children under 12 years of age. If a young child has something in their eye or is experiencing irritation, seek advice from a pharmacist or GP promptly.

What are the alternatives to Optrex Multi Action Eye Wash?

Alternatives include sterile saline eye rinses, lubricating eye drops containing hyaluronic acid, and preservative-free artificial tear formulations. You can explore the full range of options in our eye care collection. Your pharmacist can help you choose the most appropriate product based on your specific symptoms.

How long can I use Optrex Multi Action Eye Wash for?

This product is intended for short-term use to manage mild, temporary eye irritation. If you find yourself needing to use it regularly over a prolonged period, this may indicate an underlying condition that warrants a professional assessment. Speak to your GP or optometrist if symptoms persist beyond a few days.

How should I store Optrex Multi Action Eye Wash after opening?

Once opened, store the bottle below 25°C away from direct sunlight and discard any remaining solution after 28 days. Do not freeze the product or store it in a humid environment such as a bathroom. Always check the expiry date on the bottle before use.

Can I use Optrex Multi Action Eye Wash if I have conjunctivitis?

No — this product is not a treatment for conjunctivitis or any eye infection. If you have symptoms such as a sticky or purulent discharge, significant redness, or crusting around the eyelids, you should see your GP or pharmacist for appropriate treatment. Using an eye wash alone will not clear an infection.

What happens if I accidentally swallow some of the eye wash solution?

If a small amount is accidentally swallowed, it is unlikely to cause serious harm, but you should contact NHS 111 or your nearest pharmacist for advice. Keep the product out of the reach of children to prevent accidental ingestion. In the event of a large amount being swallowed, contact the NHS 111 service or go to your nearest A&E.

Can I use Optrex Multi Action Eye Wash if my eyes are irritated by hay fever?

Yes — this eye wash can help rinse away pollen and other airborne allergens from the eye surface, providing temporary relief from hay fever-related eye irritation. For more complete hay fever management, you may also want to explore our allergy and hay fever range, which includes antihistamine eye drops and oral treatments. Combining approaches often gives better overall symptom control.

What is the latest guidance on using eye washes for eye irritation?

Current NHS guidance recommends that mild eye irritation caused by environmental factors can be managed at home with gentle cleansing measures, including the use of an appropriate eye wash. However, if symptoms are severe, persistent, or accompanied by vision changes, professional assessment is always recommended. Always follow the product instructions and seek advice if you are unsure.

How Should You Use Optrex Multi Action Eye Wash?

Always wash your hands thoroughly before handling the eye bath or bottle. Remove contact lenses before starting and ensure the eye bath is clean. Use fresh solution for each eye — never reuse solution from a previous application, as this could introduce bacteria to the eye surface.

What Is the Correct Dose of Optrex Multi Action Eye Wash?

The dose is determined by filling the eye bath to the halfway mark for each application. There is no fixed volume measurement required — the eye bath is designed to hold the appropriate amount of solution for a single rinse. Always use fresh solution for each eye and each application session.

When Is the Best Time to Use Optrex Multi Action Eye Wash?

You can use this eye wash at any time of day when your eyes feel sore, gritty, or irritated. Many people find it particularly helpful after returning indoors from a dusty or polluted environment, after swimming in a chlorinated pool, or at the end of a long day in front of a screen. Using it before bed can also help clear any accumulated irritants from the eye surface overnight.

If you are using other eye drops or ointments, wait at least 5 minutes between applications to avoid diluting the other product. Always remove contact lenses before use and wait at least 15 minutes before reinserting them.

How Long Can You Use Optrex Multi Action Eye Wash For?

This product is designed for short-term use to manage mild, temporary eye irritation. Once opened, the bottle should be discarded after 28 days regardless of how much solution remains. If your symptoms persist beyond 48 hours of regular use, or if they worsen at any point, stop using the product and seek advice from your pharmacist or GP.

Prolonged or frequent need for an eye wash may indicate an underlying condition — such as blepharitis, dry eye syndrome, or an allergy — that requires a more targeted treatment approach. Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Optrex Multi Action Eye Wash?

Most people use this product without experiencing any significant side effects. However, as with any topical eye product, some mild reactions can occur, particularly in people with sensitive eyes or a sensitivity to plant-derived ingredients.

  • Temporary stinging or burning sensation immediately after instillation
  • Transient blurred vision lasting a few minutes after use
  • Mild watering or tearing of the eye
  • A brief sensation of warmth or tingling around the eye

These effects are generally short-lived and resolve without any treatment. If the stinging or blurring persists for more than a few minutes, discontinue use and seek pharmacist advice.

What Are the Less Common Side Effects of Optrex Multi Action Eye Wash?

Less commonly, some individuals may experience a more pronounced reaction to the witch hazel or other ingredients in the formulation. These reactions are not typical but are worth being aware of before you start using the product.

  • Increased redness or irritation of the eye or surrounding skin
  • Eyelid swelling or puffiness
  • Persistent discomfort that does not resolve after a few minutes
  • Sensitivity to light following use

If you notice any of these less common effects, stop using the product immediately and consult your pharmacist or GP. Do not continue using the eye wash in the hope that the reaction will settle on its own.

What Are the Serious Side Effects of Optrex Multi Action Eye Wash?

Serious side effects are rare with this product, but you should be aware of the signs of an allergic reaction. Symptoms of a serious allergic reaction (anaphylaxis) include swelling of the face, lips, or throat, difficulty breathing, a widespread rash, or a sudden drop in blood pressure. If you experience any of these symptoms after using this eye wash, call 999 or go to your nearest A&E immediately.

Any sudden change in vision, severe eye pain, or the appearance of halos around lights following use should also be treated as a medical emergency. Do not delay seeking help in these situations.

What Should You Do If You Experience Side Effects?

For mild side effects such as temporary stinging or blurred vision, simply wait a few minutes — these usually resolve on their own. Avoid driving or operating machinery until your vision has fully cleared. If side effects are more persistent or concerning, stop using the product and speak to your pharmacist before using it again.

You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. This helps the MHRA monitor the safety of medicines available in the UK.

Can Optrex Multi Action Eye Wash Interact With Other Medicines?

No clinically significant drug interactions are currently known for this topical eye wash. However, if you are using other eye drops, eye ointments, or any other topical ocular preparations, you should wait at least 5 minutes between applications. This prevents the eye wash from diluting or washing away the other product before it has had time to work. Always inform your pharmacist of all medicines you are currently using, including over-the-counter products.

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