What is cromolyn sodium?

Cromolyn sodium is a medication (often used as cromolyn sodium inhalation solution or as cromolyn sodium eye drops) that helps prevent certain allergy-related symptoms, especially those triggered by mast cells. It works by stabilizing mast cells so they release fewer inflammatory chemicals during an allergic response.

What is it used for?

Depending on the formulation, cromolyn sodium is commonly used for conditions such as:
- Prevention of asthma symptoms triggered by allergies (typically as a controller/preventive therapy rather than a rescue inhaler).
- Allergy-related eye symptoms (in some patients, via cromolyn eye drops for prevention/control of symptoms).

How does cromolyn sodium work?

Cromolyn sodium acts as a mast cell stabilizer. By preventing mast cells from degranulating, it reduces the release of mediators like histamine, which can drive allergy symptoms such as airway inflammation or itchy, watery eyes.

Does it work fast like a rescue inhaler?

No. Cromolyn sodium is generally used for prevention/control. It is not typically intended for quick relief of sudden asthma attacks or acute severe allergy flares.

What forms does it come in?

Commonly, cromolyn sodium is prescribed as:
- Inhalation formulations for lung/allergy-triggered asthma prevention.
- Eye drop formulations for allergic eye symptoms.
