Overview

Allergic eye symptoms like relentless itching, redness, and watering can make everyday life exhausting. Opatanol eye drops provide fast, targeted relief directly where it’s needed, calming irritation and restoring clear, comfortable vision. As the branded version of Olopatadine, Opatanol offers trusted, prescription-strength relief — helping you face the day with clear eyes and confidence.

This medicine requires a secure online consultation with a UK-registered prescriber, and will only be supplied if clinically appropriate.


What is Opatanol 


Opatanol contains olopatadine hydrochloride, a powerful antihistamine eye drop used to treat seasonal allergic conjunctivitis — the red, itchy, and watery eye symptoms triggered by hay fever, dust, pets, or other allergens.

It works in two ways: by blocking histamine, which prevents the release of the chemical responsible for itching and redness, and by reducing inflammation, helping to ease irritation and swelling in the eyes.

Relief usually begins within minutes of application, with each dose lasting for up to 8 hours. Because it works directly in the eyes, Opatanol provides targeted relief right where it’s needed most. As the branded version of olopatadine, it is widely prescribed and trusted for effective control of allergy-related eye symptoms.

Directions

  • Adults and children aged 12+: One drop in each affected eye, twice daily (every 8–12 hours)
  • Do not exceed two doses per day
  • Wash hands thoroughly before use
  • Avoid touching the dropper tip to the eye or any surface
  • Remove contact lenses before use, and wait at least 15 minutes before putting them back in


Always follow the instructions given by your prescriber.

Side Effects

Like all medicines, Opatanol eye drops can cause side effects, although not everyone will experience them. Most are mild, short-lived, and improve as your eyes adjust to treatment.

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

  • Temporary stinging or burning after application – this usually settles within a few minutes of using the drops.
  • Dry eyes – some people may notice a temporary feeling of dryness or grittiness.
  • Headache – typically mild and short-lived.


Less common (may affect up to 1 in 100 people):

  • Blurred vision – temporary blurring may occur immediately after use; avoid driving or operating machinery until your vision clears.
  • Bitter or unusual taste in the mouth – this may happen if some solution drains into the throat but usually passes quickly.
  • Tiredness – a small number of people may feel slightly fatigued.


Rare but serious (seek urgent medical help):

  • Severe allergic reaction (anaphylaxis) – symptoms include swelling of the face, lips, tongue, or throat, difficulty breathing, or a sudden rash. This is very rare but requires immediate emergency care.


Most people tolerate Opatanol well, and side effects (if they do occur) are generally mild. If you are concerned about any symptoms, or if they do not improve, speak to your doctor, pharmacist, or prescriber.

Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet that comes with your medicine for full details. If you experience severe or worrying symptoms, seek medical advice straight away. In an emergency, call 999 or go to A&E.

Warnings

Opatanol may not be suitable if you:

  • Are allergic to olopatadine or any of the ingredients
