Uses

What is Cromolyn sodium (Oral) used for?

Cromolyn sodium (Oral) is commonly used to treat mastocytosis, a disease that occurs when the body has too many mast cells. These normal body cells release substances (e.g., histamines) that are needed for normal body defense and healing, but when too many mast cells are present, they release too much of these substances. This can lead to symptoms such as diarrhea, stomach/abdominal pain, itching, rash, and flushing. Cromolyn belongs to a class of medications called mast cell stabilizers. It works by preventing mast cells from releasing the substances that can cause these skin and gut problems.

How should I take Cromolyn sodium (Oral)?

Take this medication by mouth 30 minutes before meals and at bedtime, usually 4 times daily or as directed by your doctor. If you are using this drug to prevent a food allergy or for inflammatory bowel disease, your doctor may direct you to take it 15-20 minutes before meals.
