Sodium cromoglicate prevents mast cells from releasing histamine, which helps reduce inflammation and allergic symptoms.

Sodium cromoglicate is commonly prescribed for:
- Hay fever (allergic rhinitis) (to reduce sneezing, itching, and nasal congestion)

- Asthma (to help prevent asthma attacks triggered by allergies)
- Food allergies (in some cases, to prevent reactions when exposure cannot be avoided)
