Latex and latex-fruit syndrome
Understand latex reactions, prepare for safe care and avoid unnecessary food exclusions
In this sheet
Three essential points
Not every reaction to gloves is an immediate latex allergy
Irritation, allergic contact dermatitis caused by rubber chemicals and IgE allergy to natural rubber latex are three different situations.
A confirmed IgE latex allergy must be reported before healthcare procedures
It may cause contact hives, swelling, rhinitis, asthma and sometimes anaphylaxis. The team can then arrange an appropriate environment.
Latex does not mean automatically avoiding banana, avocado, kiwi or chestnut
Latex-fruit syndrome affects only some patients. Avoid foods that genuinely cause symptoms, not a theoretical list.
Reaction to gloves: three mechanisms to distinguish
- Situation
- Irritation
- Typical presentation
- Dry, red or burning skin after repeated washing, occlusion or prolonged glove use. This is not an allergy.
- Situation
- Allergic contact dermatitis
- Typical presentation
- A delayed reaction, often the next day or later, frequently caused by accelerators or other rubber additives.
- Situation
- Immediate natural latex allergy
- Typical presentation
- Within minutes of exposure: itching, hives, angioedema, rhinitis, asthma or, exceptionally, anaphylaxis.
| Situation | Typical presentation |
|---|---|
| Irritation | Dry, red or burning skin after repeated washing, occlusion or prolonged glove use. This is not an allergy. |
| Allergic contact dermatitis | A delayed reaction, often the next day or later, frequently caused by accelerators or other rubber additives. |
| Immediate natural latex allergy | Within minutes of exposure: itching, hives, angioedema, rhinitis, asthma or, exceptionally, anaphylaxis. |
Where might natural latex be encountered?
Natural latex may be present in some gloves, balloons, condoms, contraceptive or medical devices and various natural-rubber objects. Product composition changes; with a confirmed allergy, ask the professional or manufacturer when in doubt.
Prepare for healthcare and contact with latex
Healthcare, dentistry or surgery: what should I do?
For someone genuinely allergic to natural latex, the aim is to avoid relevant exposures without multiplying unnecessary restrictions. This information is particularly important before surgery or dental treatment.
Condoms and contact devices
Condoms without natural latex are available. The same principle applies to some contraceptive or medical devices: check their composition when natural latex allergy is confirmed. SOS Allergo does not recommend commercial brands.
Understand allergy assessment
How is latex allergy confirmed?
- Suspected mechanism
- Immediate reaction
- Possible investigation
- Clinical history plus exposure and symptoms, then depending on the context a skin prick test when available and appropriate, latex-specific IgE and sometimes specialist investigations.
- Suspected mechanism
- Delayed eczema
- Possible investigation
- Patch tests targeting accelerators and other rubber chemicals.
| Suspected mechanism | Possible investigation |
|---|---|
| Immediate reaction | Clinical history plus exposure and symptoms, then depending on the context a skin prick test when available and appropriate, latex-specific IgE and sometimes specialist investigations. |
| Delayed eczema | Patch tests targeting accelerators and other rubber chemicals. |
Patch tests and skin prick tests do not investigate the same process.

Why are Hev b molecules sometimes discussed?
Molecular allergology may help distinguish genuine latex sensitisation from cross-reactivity. Components such as Hev b 1, 3, 5 or 6 may support genuine sensitisation depending on the context, whereas Hev b 8, a profilin, may mainly reflect cross-reactivity. A molecule never determines management on its own.
Are nitrile gloves always the solution?
For IgE allergy to natural latex, gloves without natural latex avoid these proteins. However, some synthetic gloves may contain accelerators that cause allergic contact dermatitis. ‘Latex-free’ therefore does not necessarily mean ‘free from every allergenic substance’.
Why does latex-fruit syndrome occur?
Some latex proteins resemble proteins found in plants. The same IgE may then recognise latex and certain foods: this is latex-fruit syndrome.
Examples, not an avoidance list
Banana, avocado, kiwi and chestnut are classic associations; other plants may be involved. Latex allergy does not mean allergy to these foods.
Should I stop these foods ‘as a precaution’?
If a food causes symptoms, record the exact food, whether raw or cooked, amount, delay and symptoms. This description is often more useful than a long list of tests performed without a clinical hypothesis.
Are food reactions always mild?
No. Latex-fruit syndrome ranges from local or oral symptoms to systemic reactions. A generalised reaction, breathing difficulty, feeling faint or another significant reaction must be assessed as a genuine food allergy.
If you have been prescribed an emergency plan with adrenaline
Follow that plan. Latex allergy does not mean every patient automatically needs an auto-injector; the decision depends on the history and risk.
Read the adrenaline auto-injector sheet.Are pollen-food allergy syndrome (PFAS) and latex-fruit syndrome the same?
No. In PFAS, cross-reactivity typically starts with pollen sensitisation. In latex-fruit syndrome, it involves natural latex proteins and certain plants. Profiles may nevertheless overlap, which is why the clinical history and sometimes molecular allergology are useful.
Read the PFAS sheet.Repeated exposure and work
Who is particularly exposed to latex?
- professionals with repeated exposure, including some healthcare workers;
- people who have undergone many medical or surgical procedures, including historically highly exposed groups such as people with spina bifida;
- people who have already had suggestive reactions after contact with natural-latex objects.
Latex and work
Natural latex and rubber additives may cause contact hives, rhinitis, asthma, irritation or eczema at work. If symptoms improve at weekends or on holiday and return at work, tell your doctor and occupational physician.
Describe your occupational exposures.Prevention at work
The French National Research and Safety Institute (INRS) recommends replacing natural latex where possible and, according to risk, using suitable gloves, including powder-free low-protein gloves or appropriate synthetic materials.

Common myths
- Myth
- ‘My hands become red with gloves, so I am allergic to latex.’
- SOS Allergo message
- Not necessarily: irritation, accelerator allergy and immediate latex allergy are different.
- Myth
- ‘A nitrile glove can never cause an allergy.’
- SOS Allergo message
- False: some synthetic gloves contain accelerators that cause eczema.
- Myth
- ‘Positive latex IgE means definite allergy.’
- SOS Allergo message
- No. The result must fit the clinical history.
- Myth
- ‘Latex allergy means no banana, kiwi, avocado or chestnut.’
- SOS Allergo message
- False. Do not remove tolerated foods.
- Myth
- ‘Kiwi allergy means latex allergy.’
- SOS Allergo message
- Not automatically.
- Myth
- ‘Latex-fruit syndrome is always mild.’
- SOS Allergo message
- No. Systemic reactions are possible.

Key points
Precisely identifying the mechanism avoids two extremes: underestimating a genuine latex allergy before healthcare, or unnecessarily removing foods and materials that are well tolerated.
