Choosing Generic Vs Branded Sodium Cromoglicate Eye drops


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.

Sodium Cromoglicate

What is Sodium Cromoglicate?

Sodium Cromoglicate is an eye drop used to treat allergic conjunctivitis (hay fever) by reducing the redness, itch, watering and irritation of the eyes associated with the condition. Sodium Cromoglicate works by stabilising the mast cells that release histamine.

Using Sodium Cromoglicate

How should I use Sodium Cromoglicate?

For best results, these eye drops should be used four times a day.

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.

Allergic Conjunctivitis 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 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.

Side Effects

What side effects may I experience?

Temporary stinging or burning may occur after using the drops.
