Can I Be Allergic to Rats?

Although it is not common, some people may be allergic to rats. If this is the case, they can try to reduce their exposure to rats and other allergens. Allergists can also test for rat allergies by giving a blood test. This test measures the level of IgE antibodies, which are responsible for an allergic reaction. The antibodies are specific to rat and pet allergens.

Symptoms of an allergy to rats can include hives, sneezing, congestion, and coughing. Over-the-counter medicines like Clariton, Zirtec, and Benedryl may help alleviate the symptoms. In more severe cases, an allergy to rats may require a trip to an allergist, who can prescribe medicine.

People with rat allergies should wash their hands frequently to limit their exposure to allergens. A surgical mask is also recommended, which will prevent inhalation of the allergens. Keeping the rat cage clean can also help minimize allergic symptoms. Cage contents should be changed daily or every two days.

Atopy and genetic susceptibility are important risk factors for rodent allergies. The highest risk for sensitization and development of symptoms occurs in individuals who work with animals. Health care workers should be especially careful in handling animals, as rodent bites can result in life-threatening anaphylaxis.
