Choosing Generic Vs Branded Opatanol Eye Drops

X

Generic medicines contain the same active ingredient and are equally effective and medically equivalent as the branded products but are available at a lower price. Generic manufacturers have to demonstrate that they are medically identical to the branded product - i.e. they offer the same quality, strength, stability and effectiveness.

Generic medicines are required meet the same standards of safety, quality and efficacy as the branded medication. To receive market approval from the European Medicines Agency and MHRA, a generic medicine must be 'bioequivalent' to the originator product.

Opatanol

What is Opatanol?

Opatanol 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.

Opatanol 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.

Using Opatanol

How should I use Opatanol?

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.

Opatanol Information

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 Opatanol.

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.

Side Effects

What side effects may I experience?

Opatanol 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 Opatanol?

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