What is a latex allergy?

Natural rubber latex is a milky fluid found in rubber trees. There is a protein in the fluid that can cause allergic reactions in some people. Common products made using this natural rubber latex include gloves, condoms, rubber bands, and balloons.

There are 2 types of latex allergy. One type can cause a reaction right away. For example, it's like what someone with a peanut allergy may have after eating a peanut. The other type is much more common. It causes a delayed skin rash 1 to 3 days after exposure. This is similar to a reaction that often occurs after you have been exposed to poison ivy.

What causes a latex allergy?

An allergy is an extreme sensitivity to a certain substance (allergen). Latex protein is the allergen that causes a latex allergy. People with a latex allergy have a reaction when latex comes in contact with their skin, or with mucous membranes (such as the nostrils, mouth, or rectum), or the bloodstream (during surgery). For example, some people may react when blowing up a rubber balloon or breathing in powder from the inside of latex gloves.
