Quick summary

Opatanol 1mg/ml eye drops solution contains olopatadine and is used for symptoms of allergic conjunctivitis, such as itchy, red, or watery eyes. Follow the Patient Information Leaflet and your prescriber’s instructions for correct use.

What are Opatanol eye drops?

Opatanol 1mg/ml eye drops solution is a prescription medicine manufactured by Novartis Ireland Limited. It is used to help relieve eye symptoms linked to allergic conjunctivitis.

The active ingredient is olopatadine, an antihistamine used in the eye. The product is supplied as a 1mg/ml solution and is applied directly into the affected eye.

Always read the Patient Information Leaflet (PIL) supplied with the medicine for the most up-to-date instructions and warnings.

How do Opatanol eye drops work?

Opatanol works by helping to reduce the allergic response in the eye. The leaflet information describes olopatadine as an antihistamine that helps block the effects of histamine, which is involved in allergy symptoms.

This may help ease symptoms such as itching, redness, and swelling associated with allergic conjunctivitis.

How are Opatanol eye drops used?

The medicine is typically used as directed by the prescriber. The current content states that it is usually administered twice daily, with a drop placed into the conjunctival sac of the affected eye.

General eye-drop technique may include:

  1. Wash your hands before use.
  2. Shake the bottle gently if instructed in the leaflet.
  3. Tilt your head back and pull down the lower eyelid.
  4. Place one drop into the pocket formed by the lower lid.
  5. Close the eye gently after use.
  6. Avoid touching the dropper tip to the eye or any surface.

If you use other eye medicines, check the leaflet or ask a pharmacist about spacing them apart.

What side effects are mentioned for Opatanol?

The current content lists the following possible side effects:

  • Eye irritation or burning sensation
  • Dry eyes
  • Headache
  • Blurred vision

These effects are described as usually mild and temporary. If you notice a severe reaction, such as swelling of the face or difficulty breathing, seek urgent medical help.

Who should be careful with Opatanol?

Opatanol may not be suitable for everyone. The current content says it should not be used by people who are allergic to olopatadine or any other ingredient in the product.

Extra caution is advised if you:

  • Have a history of eye problems
  • Are pregnant or breastfeeding
  • Have had eye surgery or are under care for an eye condition

The content also notes that benzalkonium chloride may irritate sensitive eyes. For personal advice, check the leaflet and speak with a healthcare professional.

What should you check before using it?

Before using Opatanol, it is sensible to confirm the following with the PIL or a pharmacist:

  • Whether the medicine is intended for your symptoms
  • How often to use it
  • How long to continue treatment
  • Whether it can be used with other eye drops
  • Any ingredient warnings listed in the leaflet

The current content states that Opatanol is a prescription-only medicine and may be obtained from licensed pharmacies with a valid prescription.
