Alpha-gal Syndrome

an allergy and a tick-borne condition

AGS is a serious, potentially life-threatening allergy to alpha-gal (galactose-alpha-1,3-galactose), a sugar found in most mammals, except for old world monkeys, apes, and people. Products made from or containing ingredients derived from mammals, including many foods and drugs, can also contain alpha-gal.

More than 60% of people with AGS have life-threatening, anaphylactic reactions,1,2,3 and a number of fatalities have occurred as a result of reactions to alpha-gal.4,5,6

Tick bites cause AGS.7In the United States, most cases are associated with lone star ticks, which are most common in the southern, midwestern, and mid-Atlantic United States.8
