The term latex allergy refers to the protein in the extract of the Brazilian rubber tree (Hevea brasiliensis). It also means “natural rubber products” made from this core. Latex is found in many products:
- Rubber bands
- Condoms and diaphragms
- Household rubber gloves
- Rubber balls
- Bandages etc.
Latex Allergy Symptoms
Common early symptoms are swelling, redness and itching after contact with latex substances:
- Itchy or swollen lips after inflating a balloon
- Itchy, red, or swollen skin after using a bandage
- Swelling or itching of the mouth or tongue after a dentist uses latex gloves
- Itching or swelling after vaginal or rectal examinations
- Itching or swelling after using a condom
Persons who are highly allergic to latex may experience serious reactions from contact with latex. They can react even to latex that is in the same room near latex balloons or gloves, or to latex in the air. More severe reactions can include:
- Runny nose or sneezing
- Eye inflammation
- Breathing problems, including asthma symptoms
Who gets Latex Allergy?
The highest risk occurs in children with spina bifida. Spina bifida is a condition in which the spine is not fully developed before birth. More than three in five children with spina bifida are allergic to latex. Children who have frequent medical treatments or long surgeries are also at high risk. Latex is used in many medical supplies – from gloves to tubes to enema tips.
8-17% of healthcare workers and others who regularly use latex gloves are allergic to latex. Healthcare professionals and children with other allergies and contact dermatitis are more likely to develop a latex allergy when using latex gloves.
More frequent cases of latex allergy in the 1980s and 1990s are not as common today as they used to be. Many healthcare organizations now use non-latex gloves and products.
How is a Latex Allergy Diagnosed?
If you think you may be allergic to latex, it would be helpful to consult a doctor. To diagnose a latex allergy, the doctor will ask you about your medical history and perform a physical examination. If latex allergy is suspected, a blood test may be ordered. Blood testing involves looking for latex antibodies in a blood sample. Your doctor compares the test results with your history and physical exam to diagnose a latex allergy.
Latex Allergy Treatment
If the symptoms are irritant contact dermatitis, antihistamine or corticosteroid medications may be sufficient to treat the symptoms. If the reaction is severe, you may need epinephrine, intravenous fluids and other emergency medical help. If you are allergic to latex, it is helpful to use an allergy bracelet or another type of identification for emergencies. If the doctor has recommended this, you should have two epinephrine vaccines with you against the risk of allergic shock (anaphylaxis).
Prevention of Allergy
Latex allergy can be aggravated by contact. If you know this is the case, be aware of products that have the potential to cause a reaction. Ask your doctor if you should avoid them.
