Cromolyn sodium is an anti-inflammatory medication. It works by preventing the release of substances in the body that cause inflammation. Cromolyn sodium oral is used to treat the symptoms of a condition called mastocytosis, which can cause diarrhea, nausea, vomiting, headaches, stomach pain, itchy skin, and flushing (warmth or redness under the skin). Cromolyn sodium oral may also be used for other purposes not listed in this medication guide.
Gastrocrom works by treating the production of mast cells, which release natural substances, but can be harmful when produced in excess. Gastrocrom prevents mast cells from releasing these substances.
