Catacrom Eye Drops for Allergic Conjunctivitis Relief

 

You can rely on Catacrom 2% Eye Drops to provide effective relief from the symptoms of allergic conjunctivitis. Each single-dose unit contains 2% sodium cromoglicate, a well-established anti-allergy medicine that helps control the inflammatory response in your eyes. The convenient 30-pack of 0.3ml preservative-free units ensures you have a fresh, sterile dose each time you need treatment.

These eye drops work by preventing the release of substances that cause allergic reactions in your eyes. You'll find them particularly useful during hay fever season or when exposed to other allergens like dust mites or pet dander. The catacrom eye drops come in single-use containers, eliminating the risk of contamination and making them suitable for extended use.

 

How Sodium Cromoglicate Controls Eye Allergies

 

Sodium cromoglicate works by stabilising mast cells in your eye tissues, preventing them from releasing histamine and other inflammatory substances when you encounter allergens. This action helps reduce the typical symptoms of allergic conjunctivitis including itching, redness, watering and swelling of your eyelids.

The medicine takes effect gradually, so you may need to use it regularly for several days before experiencing the full benefit. Unlike some other allergy treatments, sodium cromoglicate doesn't cause drowsiness and can be used alongside other hay fever medicines when needed. For comprehensive allergy management, you might also consider browsing our allergy and hay fever collection for additional treatment options.

 

Who Should Use These Preservative-Free Eye Drops

 

These eye drops are suitable for adults and children over 4 years old who suffer from seasonal or perennial allergic conjunctivitis. You'll benefit from this treatment if you experience regular eye symptoms triggered by environmental allergens.

The preservative-free formulation makes these drops particularly appropriate if you:

  • Have sensitive eyes that react to preservatives in other eye drops
  • Need to use eye drops frequently throughout the day
  • Wear contact lenses and require compatible eye medication
  • Experience chronic allergic conjunctivitis requiring long-term treatment

 

Why Choose Preservative-Free Single-Dose Units

 

The single-dose format offers significant advantages over multi-dose bottles. Each 0.3ml unit provides a sterile, fresh dose without the need for preservatives that can sometimes irritate sensitive eyes. This design reduces the risk of bacterial contamination that can occur with repeatedly opened bottles.

You can use these drops safely with contact lenses, as the absence of preservatives means they won't accumulate on your lens surfaces. The individual units are also convenient for travel and ensure you always have the correct dose available when symptoms occur.

 

Storage and Clinical Suitability

 

Store your Catacrom eye drops below 25°C and protect them from light. Each single-dose unit should be discarded immediately after use, even if some solution remains. Don't store opened units for later use, as this compromises the sterile nature of the product.

These drops are clinically proven for the treatment and prevention of allergic conjunctivitis. The 2% concentration provides effective symptom control while maintaining a good safety profile for regular use during allergy seasons.

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.

 

How to Apply Your Eye Drops Correctly

Wash your hands thoroughly before handling the single-dose unit. Twist off the top of one unit and tilt your head back slightly. Gently pull down your lower eyelid to create a small pocket and squeeze one or two drops into this space. Avoid touching the tip of the unit to your eye or eyelid to maintain sterility.

Recommended Dosage and Frequency

Apply one to two drops into each affected eye four times daily, or as directed by your doctor or pharmacist. For prevention of seasonal allergic conjunctivitis, you may start treatment before the expected onset of symptoms. Continue using the drops regularly throughout your exposure period to maintain effective symptom control. If you wear contact lenses, you can apply the drops while wearing them, but wait at least 15 minutes before inserting lenses after application.

Other possible side effects may include:

  • Mild eye irritation or discomfort
  • Temporary redness of the eye
  • Feeling of something in the eye
  • Dry eyes
  • Eyelid swelling
