What is latex and where is it found?
Latex is a natural product that comes from the light milky fluid extracted from the rubber tree. This milky fluid is often modified during the manufacturing process to form a latex mixture. A person can be allergic to latex or the mixture or both. Latex-containing products are many and varied (see the list below).
Common household latex products include balloons and condoms. Common medical latex products include stoppers on syringes, blood pressure cuffs, oxygen tubing, and catheters. The powder of surgical gloves was a significant problem before appropriate substitutes were developed, as the powder could be inhaled and could lead to respiratory difficulties.
What are the different types of latex-containing products?
Latex is found in numerous types of products, such as the following:
- Band-Aids
- Rubber bands
- Erasers
- Some shoes and articles of clothing
- Balloons
- Surgical gloves
- Catheters
- Condoms
- Some items of sporting equipment
- Blood pressure cuffs
- Some watch bands
- Helmets
- Toothbrush massagers
- Bowling balls
- Ventilator tubing
What causes latex allergies?
In the 1980s, with the emergence of the human immunodeficiency virus (HIV), it became increasingly important to take precautions that would prevent the spread of infectious diseases. This effort resulted in the application of universal precautions for protecting a person from infectious material, such as blood and other bodily fluids, using protective barriers. The most commonly used barrier was the latex glove. The prevalence of latex allergy peaked at 3%-9.5% in the 1990s but now has fallen to less than 1% in countries where active latex avoidance measures are practiced.
Who is at risk for developing a latex allergy?
Repeated exposure to latex is necessary for an allergy to develop. Healthcare workers exposed to latex products (such as gloves and catheters), people who require frequent surgery or catheter use, and workers in the manufacturing or distribution of latex products are at the highest risk for latex allergy. For unknown reasons, people who have surgeries on the spine or urinary tract have a much higher risk of latex allergy.
There is also an association of unique food allergy among people allergic to latex, known as the fruit latex syndrome. People allergic to latex are frequently allergic to various fruits, particularly avocado, banana, chestnut, and kiwi.
What are the symptoms of the two forms of latex allergy?
Latex allergy comes in two different forms.
One form is called a "delayed hypersensitivity," which is usually seen as an itchy skin rash at the site where the latex product contacts the skin. This rash is similar to poison ivy and is generally self-limited.
The other form is an immediate hypersensitivity reaction (also known as an IgE-mediated reaction) to latex. This type of reaction can lead to anaphylaxis, a severe and potentially life-threatening allergic reaction that can involve the skin, respiratory system, gastrointestinal system, and cardiovascular system.

QUESTION
Allergies can best be described as: See AnswerHow do healthcare professionals assess and diagnose a latex allergy?
Clinical history is the most important aspect of diagnosing any type of latex allergy. A patch test for latex could potentially be performed to diagnose a delayed hypersensitivity response to latex. For an immediate hypersensitivity response to latex, a blood test is the only approved test presently available. In the United States, there is currently no approved skin testing for an immediate hypersensitivity to latex.
What is the treatment for a latex allergy?
Strict avoidance of latex is the treatment for latex allergy. Latex-free synthetic rubber, such as neoprene, nitrile, SBR, Butyl, and Vitron are polymers available as alternatives to natural rubber. Certain individuals at risk for anaphylaxis may benefit from having an epinephrine autoinjector on hand at all times.
No current treatment is available to desensitize a person who is allergic to latex. For a delayed hypersensitivity reaction to latex, topical or oral steroids may be used to treat the rash. An anaphylactic reaction to latex should be treated promptly with injectable epinephrine, and mild reactions confined to the skin may be treated with oral antihistamines.

What Is Allergic Cascade?
The allergic cascade refers to allergic reactions that happen in the body in response to allergens. A variety of immune cells and chemical messengers participate in the allergic cascade. Symptoms of the allergic cascade range from mild swelling and itching to full-blown anaphylactic shock. Allergen avoidance and medications are used to prevent or treat allergies.Allergy (Allergies)
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.Anaphylaxis
Anaphylaxis is a serious allergic reaction that affects a number of different areas of the body at one time and can be fatal. Causes of anaphylaxis can be a food allergy, latex allergy, allergy to insect stings/bites, asthma, or other materials or conditions. Symptoms include flushing, itching, hives, anxiety, and rapid or irregular pulse. Severe symptoms may be throat and tongue swelling, swallowing, and difficulty breathing. Some disorders appear similar to anaphylaxis such as fainting, panic attacks, blood clots in the lungs, heart attacks, and septic shock. If you think that you may be having an anaphylactic reaction, seek emergency care or call 911 immediately.Antihistamine Shots (Injections)
Antihistamine shots or injections are prescription drugs used for the rapid treatment of allergic reactions, anxiety, nausea, vomiting, motion sickness, and induce sedation. The common side effects of this type of medication include dizziness, drowsiness (sleepiness), dry mouth, blurred vision, urinary retention, increased or decreased blood pressure, headache, abnormal heart rate, nausea, trouble breathing, tiredness (fatigue), and weakness.Antihistamines (Oral)
Oral antihistamines are medications used to treat symptoms of congestion, runny nose, the common cold, sneezing, itchy throat, skin rashes, hives, itching, and watery or itchy eyes. Some antihistamines also are used to treat anxiety, insomnia, and motion sickness. Common side effects of first-generation antihistamines include drowsiness, dry mouth, decreased tear production, urinary retention (trouble urinating), blurred vision, constipation, and agitation.COVID-19 vs. Allergies
Though there is some overlap in allergy and COVID-19 signs and symptoms there are also significant differences. Symptoms that they have in common include headache, fatigue, tiredness, shortness of breath, wheezing, and sore throat. Fever does not occur with allergies but is one of the defining symptoms of COVID-19 infections.Eczema
Eczema refers to skin inflammation. There are many different types of eczema that produce symptoms and signs that range from oozing blisters to crusty plaques of skin. Treatment varies depending upon the type of eczema the person has.ELISA Tests
ELISA stands for "enzyme-linked immunosorbent assay." This is a rapid immunochemical test that involves an enzyme (a protein that catalyzes a biochemical reaction). It also involves an antibody or antigen (immunologic molecules).Hay Fever (Allergic Rhinitis)
Hay fever (allergic rhinitis) is an irritation of the nose caused by pollen and is associated with the following allergic symptoms: nasal congestion, runny nose, sneezing, eye and nose itching, and tearing eyes. Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.How Long Does an Allergic Reaction Last?
Allergic reactions may last for varying lengths of time. They may take a few hours to a few days to disappear. If the exposure to the allergen continues, such as during a spring pollen season, allergic reactions may last for longer periods such as a few weeks to months.Itching (Pruritus)
Itching can be a common problem. Itches can be localized or generalized. There are many causes of itching including infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.prednisone
Prednisone is a drug that belongs to the corticosteroid drug class, and is an anti-inflammatory and immune system suppressant. It's used to treat a variety of diseases and conditions, for example: inflammatory bowel disease (Crohn's disease and ulcerative colitis), lupus, asthma, cancers, and several types of arthritis.
Common side effects are weight gain, headache, fluid retention, and muscle weakness. Other effects and adverse events include glaucoma, cataracts, obesity, facial hair growth, moon face, and growth retardation in children. This medicine also causes psychiatric problems, for example: depression, insomnia, mood swings, personality changes, and psychotic behavior. Serious side effects include reactions to diabetes drugs, infections, and necrosis of the hips and joints.Skin Rash
The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.Skin Test for Allergy
An allergy skin test helps identify triggers for one's allergic reactions. Small amounts of allergy-provoking substances (allergens) are scratched into the skin. Redness and swelling develop if one is allergic to the substance. A positive allergy skin test implies that the person has an IgE antibody response to that substance. The test is rapid, simple, and relatively safe.What Are the 4 Types of Allergic Reactions?
Allergists recognize four types of allergic reactions: Type I or anaphylactic reactions, type II or cytotoxic reactions, type III or immunocomplex reactions and type IV or cell-mediated reactions.
