Ketotifen is a medication considered by many prescribers for people dealing with ongoing allergies, asthma or MCAS.
“Ketotifen is defined as an antiallergic drug that inhibits the release of vasoactive substances from mast cells, stabilizes mast cells, and exhibits antihistaminic effects, making it effective for conditions like asthma and atopic dermatitis.”

In research, Ketotifen’s influence goes beyond the common culprit histamine. Ketotifen is one of the few medications that may offer both immediate symptom relief (antihistamine) and long-term control (mast cell stabilization)—making it desirable, especially for patients with:
- Chronic allergic conditions
- Mast Cell Activation Syndrome (MCAS)
- Complex hypersensitivity reactions
- Inflammatory allergic disorders not responding to standard therapies
