ALK is a global research-driven pharmaceutical company that focuses on prevention, diagnosis and treatment of allergies. ALK has since 1923 been working to improve the quality of life for allergy patients by developing drugs that target the cause of allergy.

ALK is the world leader in allergy vaccination (immunotherapy) - a unique treatment of the cause of allergies. The treatment induces a protective immune response that provides a sustained reduction of allergy symptoms and reduces the risk of developing asthma. ALK provides allergy vaccination injections, sublingual drops and tablets, which is the newest, best documented and most convenient treatment for patients. The portfolio of products also includes JEXT - an adrenaline used to treat severe allergic reactions (anaphylactic shock).
