Natural rubber latex, derived from the sap of the rubber tree (Hevea brasiliensis), can cause a latex allergy. Rubber exam gloves, balloons, and condoms are among the many products made from natural rubber latex. It is possible to have a severe reaction or even die from latex.   When latex particles are inhaled (breathed in) by people with latex allergies or when latex particles are physically in contact with people with latex allergies, they can experience an allergic reaction. A reaction to latex may cause skin irritation, rashes, hives, runny noses, and difficulty breathing. An allergy to latex cannot be cured. If you have this condition, you should avoid latex products and consider wearing a medical alert bracelet.   Allergies to latex can manifest in mild or severe ways. In some cases, they appear right after latex exposure, while in other cases, they may appear hours or even days later. When you come into contact with latex for the first time, you might not experience any symptoms.   As a result of skin contact with latex, symptoms such as itchiness, inflammation, redness, and swelling can occur. Itchy lips may result from blowing up a balloon, and vaginal irritation may result from sex with a partner who used a latex condom. The area where the latex touched your skin develops an itchy rash. After being exposed to latex, a rash usually appears within a day. When the rash touches other parts of your body, it can spread. Many people suffer from itchy, watery eyes as well as swelling around their noses and mouths. There is a possibility that the eyes will become swollen and red.
