Ketotifen and Cromolyn
Compounded Ketotifen & Cromolyn Sodium – Mast Cell Stabilizers for MCAS & Mastocytosis

Understanding Mast Cell Disorders
Mast cells are immune cells in the skin, gut, lungs, and connective tissues that release histamine, prostaglandins, and leukotrienes. In Mast Cell Activation Syndrome (MCAS), mastocytosis, and Hereditary Alpha Tryptasemia (HAT), they become overactive, causing flushing, hives, gastrointestinal issues, breathing problems, brain fog, and anaphylaxis. Rock Ridge Pharmacy compounds Ketotifen and Cromolyn Sodium to stabilize mast cells, relieve symptoms, and support patients in Bergen County and throughout New Jersey.
Compounded Ketotifen & Cromolyn for Mast Cell Disorders
MCAS
Mast Cell Activation Syndrome occurs when mast cells release excess mediators.
Symptoms may include flushing, hives, abdominal pain, or fatigue.
Management often combines trigger avoidance, antihistamines, and stabilizers such as Ketotifen or Cromolyn.
Mastocytosis
Mastocytosis results from increased mast cells in skin, bone marrow, or organs.
Patients may develop rashes, GI upset, or systemic flares.
Compounded Ketotifen and Cromolyn are available in capsules or alcohol-free liquids for improved tolerability.
HAT
Hereditary Alpha Tryptasemia is caused by extra copies of the tryptase gene.
Elevated levels can lead to allergy-like symptoms, joint issues, and connective tissue problems.
Management focuses on lifestyle strategies plus compounded mast cell stabilizers for relief.

How Ketotifen and Cromolyn Sodium Work
- Ketotifen and Cromolyn Sodium are mast cell stabilizers used in the treatment of Mast Cell Activation Syndrome (MCAS), mastocytosis, and Hereditary Alpha Tryptasemia (HAT). They work by preventing mast cells from releasing inflammatory mediators such as histamine, prostaglandins, and leukotrienes, which are responsible for allergic and inflammatory symptoms. Ketotifen provides dual benefits — mast cell stabilization and H₁ histamine receptor blocking — offering both prevention and symptom relief. Cromolyn Sodium focuses solely on mast cell stabilization, is non-sedating, and safe for long-term daily use.
