Mast cells are a part of everyone’s immune system, and are located throughout the body. They protect us from infection through the inflammatory process. They also are present in allergic responses, also with inflammatory responses.

Source: The Mast Cell Disease Society

When the body comes in contact with a “trigger” such as an allergen, medication, or trigger ingredient, mast cells in the body “degranulate” and release inflammatory mediators such as histamine, prostaglandins, leukotrienes, and tryptase. These substances can cause a myriad of immediate allergic-type responses which can be quite serious for those who have a mast cell disease or serious allergies.

Ketotifen is currently available in other countries.
An oral antiallergic drug developed in 1970 by Sandoz, ketotifen is approved and prescribed in Canada, Europe, and Mexico. It is often used in patients with mastocytosis, food allergies, asthma, allergic rhinitis, atopic dermatitis, and more.

Mast Cell Diseases

can cause much suffering and disability with excessive mast cell mediator release along with symptoms from the accumulation of mast cells in major organ systems.

The three major forms of mast cell diseases

  • Mast cell activation syndrome (MCAS)
  • Mastocytosis
  • Hereditary Alpha tryptasemia (HAT)

Mast Cell Activation Syndrome

is caused by the inappropriate release of inflammatory mediators, causing persistent allergic-type symptoms, which can be severe, in multiple organs throughout the body.


is caused by genetic mutations resulting in the over-activation, proliferation and accumulation of altered mast cells causing persistent and allergic-type reactions in multiple organs throughout the body.

Symptoms of mast cell disease can occur in various organs

  • Itching, hives, flushing
  • Abdominal pain, bloating, nausea, diarrhea, vomiting, reflux (GERD)
  • Blood pressure changes; palpitations, fainting
  • Respiratory: difficulty breathing, congestion
  • Brain fog, cognitive problems, anxiety/depression, headaches
