What types of latex allergy are there?

Immediate latex allergy is a reaction to natural rubber latex proteins. Signs of delayed allergic contact dermatitis may be indistinguishable from those of irritant dermatitis, so clinical assessment may be needed.

Immediate protein allergy

Immediate latex allergy is an IgE-mediated reaction to natural rubber latex proteins.

• The reaction is to rubber proteins.

Delayed reactions to chemicals

Delayed allergic contact dermatitis may look like irritant dermatitis, so clinical assessment may be needed to distinguish them.

• Ask a clinician to assess a rash that could have either cause.

Irritant dermatitis

Irritant dermatitis is described apart from true latex allergy. Its symptoms will disappear and not recur once the irritant is identified and its use is stopped.

• Identify and stop using the irritant.

The most severe latex allergy can cause anaphylaxis, including severe breathing difficulty or a fall in blood pressure.

• Chest tightness and shortness of breath can occur in highly sensitive people.
• People with severe latex reactions are advised to avoid latex.

Irritant dermatitis and delayed allergic contact dermatitis can look alike, so a clinician may need to assess the rash.

• A delayed rash may begin hours after contact and peak after 24 to 48 hours.
• After prolonged contact, the skin may become itchy, red, and inflamed, then blister or scale like eczema.
• The delayed rash may occur 6 hours to 2 days after contact, usually where the skin touched latex.
• Irritant dermatitis can appear right away or within 48 hours, so timing alone may not show the cause.
• Irritant dermatitis may cause dryness, redness, burning, stinging, or painful fluid-filled blisters.
• Irritant dermatitis can cause redness, soreness, dryness, or cracking.

Synthetic rubber is made from petrochemicals and does not contain latex proteins.

People with a known latex allergy should be aware that latex mattresses and pillows may be products of concern.

• People with severe latex allergy should not use latex products.
• Read product labels for items that may contain latex.

Latex-free mattresses can use fibers or coils instead of latex layers.

• Synthetic rubber does not contain the latex proteins linked with latex allergy.
• Naturepedic says its Latex-Free EOS Classic has no latex or polyurethane foam, including memory foam.
• Lifekind describes its Traditional as a latex-free innerspring with a coil system, cotton batting, and cotton-and-wool quilting.
• Tuft & Needle says its Protector's elastic is made of latex and may contain natural latex.

More exposure to latex proteins increases the risk of sensitization and allergic symptoms.

• After sensitization, further exposure, even at low levels, may cause a reaction.
• Regular latex exposure is more common among healthcare workers, rubber-industry workers, and people who have had many operations, especially during childhood.
• Healthcare workers are among the groups at risk because they frequently use latex gloves.

Can natural latex products still trigger symptoms despite processing?

Natural rubber latex contains proteins that can cause allergy in some people. A latex mattress retailer says washing its foam removes most or all of the proteins implicated in allergic reactions, but these facts do not establish whether processed foam can still trigger symptoms.

How can you check whether a mattress contains natural rubber latex?

Read the mattress label because foam mattresses and pillows may contain latex.

Tuft & Needle says its Protector's elastic is made of latex and may contain natural latex.
