For patients living with Mast Cell Activation Syndrome (MCAS), even small amounts of certain additives in medications can cause uncomfortable or dangerous reactions. That’s why finding the right treatment often goes beyond just the active ingredient — it’s about ensuring every component of the prescription is safe for the patient’s unique sensitivities.
MCAS can be triggered by various factors, including underlying conditions such as Lyme Disease. In many cases, commercially available medications contain fillers, dyes, preservatives, or other inactive ingredients that make them intolerable for sensitive individuals.
At King’s Pharmacy & Compounding Center, we specialize in creating custom-compounded prescriptions designed to minimize these risks. Working closely with physicians, we prepare medications that are free from unnecessary additives, giving MCAS patients a safer, more personalized path to relief.
Mast Cell Activation Syndrome (MCAS) is a disorder in which mast cells — a type of white blood cell that plays a key role in the immune system — release too many inflammatory chemicals into the body. These chemicals, called mediators, include histamine, prostaglandins, and leukotrienes, which can trigger a wide range of symptoms that affect multiple organ systems. Unlike typical allergic reactions that occur in response to a known allergen, MCAS episodes can happen spontaneously or be set off by triggers such as certain foods, medications, environmental factors, infections, or stress. Because of its complex and unpredictable nature, MCAS often requires a highly personalized treatment approach, including custom-compounded medications.
Patients with MCAS may react to even tiny amounts of inactive ingredients found in standard medications. Common problem additives can include:
For these patients, compounded medications offer a solution. By formulating each prescription from pure, pharmaceutical-grade ingredients, we can eliminate unnecessary additives and create the safest, most effective version for the individual.
