In United States, latex allergy status is managed by general medicines. Latex allergy is an IgE-mediated hypersensitivity to proteins in natural rubber latex (NRL) harvested from the Hevea brasiliensis tree. Adult prevalence in the general population is roughly 1-2%, but rises to 10-17% in healthcare workers and 30-72% in children with spina bifida who have had multiple bladder catheterizations and orthopedic procedures.
Latex allergy (ICD-10: T78.40 with sub-codes for type of reaction) is an immediate (type I) IgE-mediated hypersensitivity to one or more of at least 15 allergenic proteins (Hev b 1-15) extracted from the sap of the Hevea brasiliensis tree. Hev b 1, 3, 5, 6.01, 6.02, 7, and 11 are the major clinically relevant allergens; Hev b 5 and Hev b 6.02 dominate in healthcare workers, while Hev b 1 and Hev b 3 are more important in children with spina bifida. Mechanistically, prior sensitization produces specific IgE that binds to high-affinity FcεRI receptors on mast cells and basophils; re-exposure to latex protein cross-links these receptors, releasing histamine, tryptase, leukotrienes, and other mediators within minutes. Latex allergy is distinct from irritant contact dermatitis (a non-immune chemical irritation) and from type IV (delayed) contact dermatitis caused by rubber accelerators such as thiurams and carbamates.
The key symptoms of Latex allergy status are: Contact urticaria — itchy red wheals appearing within 5-30 minutes at sites of latex contact (hands under gloves, lips after dental work, perineum after catheterization)., Angioedema of lips, tongue, eyelids, or larynx after exposure to balloons, gloves, condoms, or dental dam., Allergic rhinitis with sneezing, nasal congestion, and rhinorrhea on inhalation of latex glove powder aerosols., Asthma symptoms (wheeze, cough, chest tightness, shortness of breath) in latex-sensitized workers, especially in glove-use environments., Conjunctivitis with itchy watery eyes after direct or aerosol exposure., Generalized urticaria and pruritus extending beyond the contact site within 15-60 minutes of exposure., Gastrointestinal symptoms — nausea, abdominal cramps, vomiting, diarrhea — particularly with mucosal exposure during surgical or dental procedures..
Diagnosis begins with a structured history of reactions in healthcare, dental, and household settings, including timing relative to exposure, severity, and any history of cross-reactive food reactions. The clinician maps every potential latex contact in the patient's life — gloves, condoms, balloons, toys, elastic clothing, catheters, dental work — and identifies a temporal pattern. Skin-prick testing with standardized natural rubber latex extract is the reference standard in countries where the extract is licensed; sensitivity is 95-99% and specificity 95-100%. Where licensed extract is unavailable (notably the United States), the use-test with a latex glove (finger of a glove dampened and applied to the skin or briefly worn) under controlled conditions is acceptable with full resuscitation equipment available. Serum latex-specific IgE (CAP-FEIA, ImmunoCAP) and component-resolved diagnostics (Hev b 1, 3, 5, 6.01, 6.02, 11) refine the diagnosis and identify true allergens versus cross-reactive carbohydrate determinants. Component testing distinguishes occupational sensitization profiles (Hev b 5, 6.02 dominant) from spina bifida profiles (Hev b 1, 3 dominant). Tryptase measurement within 60-120 minutes of an acute reaction supports anaphylaxis and can be repeated at baseline 24 hours later. Patch testing identifies coexisting type IV contact dermatitis to rubber accelerators. A negative skin and serum test in a patient with a convincing history may warrant a supervised challenge in specialist allergy units.
With strict avoidance, latex allergy is well controlled in the great majority of patients. Healthcare workers who switch to synthetic gloves and avoid powder-contaminated environments achieve symptom remission in 80-95% within 6-12 months, although established latex-induced asthma may persist long-term. The risk of fatal anaphylaxis is virtually eliminated when latex-safe protocols are in place for surgery, dental work, and obstetric care. Children with spina bifida born into latex-safe environments now have sensitization rates of 10-20% versus 30-72% in older cohorts. Sensitization typically persists for years; specific IgE may slowly decline but rarely disappears entirely. Occupational asthma diagnosed and avoided within the first year has a 70-85% probability of remission, falling below 30% once disease has been established for over 5 years.
Latex allergy ranges from mild contact urticaria to fatal intraoperative anaphylaxis, and the diagnosis affects every future medical encounter. An allergy and immunology specialist confirms the diagnosis with appropriate testing, identifies cross-reactive foods, prescribes epinephrine auto-injectors, and coordinates latex-safe protocols with anesthesia, surgery, dental, and obstetric teams.
Find specialists →Acute reactions resolve within minutes to hours of treatment. Occupational symptoms in healthcare workers improve over 4-12 weeks of latex-safe glove use. Latex-specific IgE titers fall slowly over 5-10 years of strict avoidance, and skin test reactivity may diminish but rarely returns to negative without persistent sensitization.
Exercise is safe and encouraged. Avoid balloons in birthday or fitness settings, use synthetic exercise mats and resistance bands, and inspect gym equipment for latex grips. Carry epinephrine in case of exercise-induced reactions to a recently eaten cross-reactive food.
Choose an allergist with experience in occupational allergy and access to standardized latex extract, serum specific IgE, and component-resolved diagnostics. Patients with anaphylaxis should be seen at a center with a written latex-safe protocol covering inpatient and outpatient care.
