Symptoms associated with latex allergies differ depending on the nature of the allergen that triggers the reaction. Though some people react to latex itself, others react to chemical additives used to make latex-based products. 

Allergies to the chemical additives used in manufacturing rubber latex typically manifest as contact dermatitis. This is a rash that resembles poison ivy. It is caused by close contact with latex, usually in the form of latex gloves. As a result, healthcare workers are particularly susceptible to this form of latex allergy. Symptoms appear within 24 hours of exposure and include:

• Red, cracked and blistered skin
• Skin burning, itching and dryness
• Scaling or skin lesions

Latex allergies to the latex protein itself produce more serious symptoms similar to those of allergic rhinitis or asthma. This type of reaction may be triggered by skin contact with latex protein or the inhalation of airborne latex particles. Symptoms can appear within minutes of exposure and may include:

• Stuffy or runny nose
• Coughing
• Sneezing
• Hives or rash
• Itchy skin
• Itchy or watery eyes
• Chest tightness
• Breathing problems (e.g., wheezing)
• Shortness of breath

In rare cases, allergies to the latex protein can trigger life-threatening anaphylactic shock. In highly sensitive individuals, anaphylactic reactions typically develop immediately after latex exposure. They may cause the bronchi to constrict, making it difficult to breathe. Blood pressure may also drop to dangerous levels. Signs and symptoms of anaphylaxis include:

• Swelling of the throat, tongue or nose
• Wheezing
• Confusion
• Slurred speech
• Low blood pressure
• Rapid or weak pulse
• Bluish tint in the skin, lips and nail beds (cyanosis)
• Diarrhea
• Nausea and vomiting
• Faintness
• Loss of consciousness

Immediate medical treatment should be sought for anyone having an anaphylactic reaction.
