Hives
What causes hives on skin?
Hives, a skin rash that's often very itchy, often results from an allergic reaction to food or something you haved touched. Hives can go away quickly (acute hives) or last a long time (chronic hives). Treatments may include antihistamines or steroids.
Allergic reactions
- foods (such as nuts, milk, and eggs)
- pet dander
- pollen
- dust mites
- insect bites or stings
- medications (primarily antibiotics, cancer drugs, or ibuprofen)
How can I prevent hives?
Your healthcare provider can use the results of allergy tests to help you figure out which substances bring on acute hives. Once you know your triggers, you can avoid them. You may want to:
- Cut certain food products out of your diet.
- Reduce exposure to airborne allergens.
- Switch to detergents and soaps without scents or dyes.
- Avoid extreme changes in temperature.
- Relax and take a break when you’re stressed or overworked.
- Wear loose-fitting, lightweight clothing.
