✨ Ketotifen & MCAS: What to Know ✨
Mast Cell Activation Syndrome (MCAS) can trigger a wide range of symptoms, including flushing, itching, hives, GI discomfort, headaches, fatigue, and more, due to mast cells releasing mediators too easily.
Ketotifen is a unique medication that works in two ways:
✔️ As an antihistamine
✔️ As a mast cell stabilizer
This means it can help calm mast cell activity and may be able to reduce symptoms when traditional antihistamines aren’t enough.
Compounded ketotifen allows prescribers to customize strength and dosage forms, to help make it easier to support those dealing with persistent allergy-type symptoms or MCAS.
