Olopatadine Eye Drops

What is Olopatadine?

Olopatadine is a prescription-only eye drop used to treat allergic conjunctivitis (hay fever) by reducing the redness, itch, watering and irritation of the eyes associated with the condition.

Olopatadine works by stabilising the mast cells that release histamine. It’s similar to Sodium Cromoglicate, but can be used less frequently (twice daily) as it provides more sustained relief of symptoms.

How should I use Olopatadine?

One drop should be instilled into each eye, twice daily.

When can I expect to see results?

Relief from symptoms will usually occur within 24 hours. If more than 72 hours have passed without symptom relief then an alternative diagnosis should be considered.

For best results, the drops should be used every day through your hay fever season. It is safe to use the drops for up to 4 months at a time without a break.

What is allergic conjunctivitis?

Allergic conjunctivitis is the name given to eye inflammation caused by allergies, such as hay fever.

This inflammation causes itching, redness and watering. It can also lead to eye discharge, or inflamed, itchy eyelids.

What causes allergic conjunctivitis?

Allergic conjunctivitis is typically triggered by exposure to pollen from trees and flowers, or animal hair and pet dander. These allergens trigger cells within our immune system (mast cells) to release histamine, which leads to irritation.

What treatments are available for allergic conjunctivitis?

Allergic conjunctivitis can be treated with anti-allergy drops, like Sodium Cromoglicate or Olopatadine.

If you experience additional hay fever or allergy symptoms, such as an itchy throat or runny nose, antihistamine tablets can provide extra relief alongside eye drops.

What side effects may I experience?

Olopatadine is well tolerated and side effects are not common. It can cause a feeling of dry eyes and irritation. Very rarely, it can cause an allergic reaction — if you experience this, you should avoid these drops in the future.

Is there anybody who should not use Olopatadine?

It is not suitable for women that are pregnant or breastfeeding.
