Disposable Glove Allergies

Latex Allergy

Causes

Latex allergy results from proteins contained in natural rubber latex, a milky substance found in the rubber tree (Hevea Brasiliensis). Exposure to latex proteins is possible via skin contact or inhalation. Inhalation most commonly occurs when donning powder, containing proteins which have leached to the cornstarch, become airborne when changing gloves.

Prevalence

Only about 2% of the population experiences latex allergy symptoms. While the level of exposure to latex required to illicit a reaction remains unknown, those frequently exposed seem to be at the greatest risk for an allergic reaction. Prevalence is highest among healthcare workers and children with spina bifida, where exposure to latex is common. People highly sensitive to other allergies, particularly to certain types of food, are also more likely to have a reaction.

Symptoms

An allergic reaction to latex may be characterized by one or more of the following symptoms:

Sneezing and running nose

Itchy or watery eyes

Cough

Eye irritation

Skin rash or hives at the point of contact

Shortness of breath

Low blood pressure

Nausea and vomiting

Dizziness

Although uncommon, allergic reactions can be fatal for those highly sensitive to latex.

Treatment & Prevention

The best treatment for latex allergy is to avoid contact with latex products. Non-latex gloves exist as suitable alternatives. Use of powder-free gloves can also reduce the risk of latex proteins become airborne.

If during use of a product containing latex you experience a reaction, consult a doctor. For more serious symptoms, such as shortness of breath, seek emergency care immediately.

Allergies to Nitrile and Other Non-Latex Gloves

Reports of allergic reactions to non-latex gloves like nitrile have become more common in recent years as industries like healthcare shift to latex-free alternatives. While research on the topic remains extremely limited, several theories have emerged suggesting possible causes of allergic reactions.

Possible Causes

Latex Contamination

When reports of reactions first surfaced more than a decade ago, many assumed that since latex gloves were often being manufactured in the same facilities as nitrile gloves, that the nitrile gloves were being contaminated with latex proteins.

Accelerators

Some argue that allergic reactions to non-latex gloves are due to chemicals called accelerators used during production. They believe that accelerators, such as carbonates and thiurams, may cause a delayed (Type IV) reaction to these chemicals. The Food and Drug Administration has approved marketing "accelerator free" nitrile gloves as non-allergenic, but reactions to the gloves have still been reported.

Ventilation

Most gloves are intended to prevent chemicals and other contaminants from permeating in or out of the glove. Consequently, some glove materials offer better ventilation than others. Skin irritation called urticaria (more commonly referred to as hives) can sometimes occur when a glove lacks breathability and moisture builds up under the glove.

Glove Leakage

Some glove materials will begin to leak if worn longer than they are intended for use. Consequently, some allergic reactions may actually be to chemicals leaking through the glove instead of the glove material itself. These reactions can be prevented by consulting with your glove supplier to determine the proper length of time a glove should be worn, as usage length varies by glove type.

Prevalence

It is widely believed that allergic reactions to non-latex gloves are far less prevalent than those to natural rubber latex. Estimates of prevalence, both of the population at-large and within industries with frequent non-latex glove usage, are unknown.

Treatment & Prevention

Try powder-free alternative glove types if a reaction to nitrile or other non-latex gloves occurs. When possible, increasing the frequency with which you change gloves may also help reduce the potential for a reaction. Consult with your glove supplier if using lotions or other moisturizers, as these may weaken the glove's barrier resistance. If problems persist, consult your doctor. For more serious symptoms, such as shortness of breath, seek emergency care immediately.
