Hi i am allergic to pet dander and when in contact with it i get hives so how long will my hives last?

Hives: Depends on how long you are exposed to the dander. If it gets on your clothes, they need to be changed or washed to reduce skin exposure. Hives typically last less than 24 hours once the allergic trigger is removed but this can be sped up if oral antihistamines are used.
