UNDERSTANDING THE CONDITION
What is urticaria?
Urticaria causes raised, itchy skin swellings called wheals, often triggered by release of histamine and other mediators from skin mast cells. Each individual wheal typically fades within 24 hours, although new ones may appear elsewhere. Hives are not contagious and do not always mean food allergy.

MBBS + MDBoth from IMS-BHU01 / RECOGNISE THE PATTERN
Not all hives behave the same way
The timing of the rash and what brings it on often tell the dermatologist more than a long list of allergy tests.
Chronic spontaneous urticaria
Recurrent wheals, swelling or both for six weeks or longer, often with no consistent outside trigger.
Physical or inducible hives
May follow scratching, pressure, cold, heat, vibration or body warming. The pattern guides any provocation testing.
Angioedema
Deeper swelling may affect lips, eyelids or other areas. Isolated or recurrent swelling sometimes needs a different evaluation.
Emergency warning: swelling with breathing or circulation symptoms
If hives or swelling occur with breathing difficulty, throat or tongue swelling, fainting or collapse, seek emergency care immediately. Suspected anaphylaxis needs prompt emergency treatment, including intramuscular adrenaline when indicated; antihistamines alone are not sufficient.
02 / WHY HIVES RETURN
Why do hives keep coming back?
Chronic spontaneous urticaria involves recurring activation of skin mast cells and may have an autoimmune basis. It is usually not caused by an undetected food allergy.
Mast cells and histamine
Skin mast cells release substances that cause temporary swelling and itching. The precise reason may not be identifiable in every patient.
Heat, pressure and medicines
In susceptible patients, overheating, rubbing, tight clothing or medicines such as some painkillers (NSAIDs) may worsen hives.
Not every episode is an allergy
A broad food allergy panel is generally unhelpful for chronic spontaneous urticaria without a convincing immediate-reaction history.
Important: Avoid blaming every flare on a meal or removing multiple foods without evidence. When a specific food or medicine repeatedly causes symptoms soon after exposure, a focused allergy assessment may be appropriate.
03 / WHEN TO SEEK REVIEW
When should recurring hives be examined?
Most hives are not dangerous, but some patterns deserve prompt review or a different diagnosis.
Hives for six weeks or longer
Wheals or swelling that recur for six weeks or longer, disrupt sleep or require frequent medication deserve a structured assessment and control plan.
Painful marks lasting over 24 hours
Individual lesions that persist, bruise or leave discolouration may suggest another diagnosis such as urticarial vasculitis.
Swelling without typical wheals
Recurrent lip or facial swelling, especially without wheals, may need a separate assessment for other forms of angioedema.
Why does swelling sometimes happen without hives?
Not all angioedema is caused by the same mechanism. The symptoms, medicines being taken and family history help guide assessment.
Mast-cell-mediated swelling
May accompany itchy hives, but can also occur alone. It often improves with appropriate antihistamine treatment.
Other causes of angioedema
Recurrent swelling without wheals may warrant a medication review (especially ACE inhibitors) and, in selected cases, C4 and C1-inhibitor testing for bradykinin-mediated angioedema. These forms may not respond to antihistamines.
Emergency: Tongue or throat swelling, difficulty breathing or faintness requires immediate emergency care, even when no hives are visible.
YOUR CONSULTATION / WHAT TO EXPECT
How is urticaria assessed?
The aim is to identify the pattern, recognise danger signs, choose appropriate investigations and build a practical treatment plan.
History and photographs
Discuss duration of each wheal, recurrence, swelling, medicines, possible triggers and any accompanying illness. Photos help when the skin looks normal at the visit.
Classify the type
Distinguish acute, chronic spontaneous and inducible urticaria; consider other diagnoses for atypical or persistent lesions.
Test only if helpful
Investigations may be limited or guided by history and examination. Specific provocation or blood tests are used selectively.
Control and follow-up
Choose regular treatment when appropriate and review symptom control, side effects and the need to adjust the plan.
Which investigations may actually help?
Tests depend on the type of urticaria and the history; broad panels are not routinely needed.
Routine blood or allergy testing is usually unnecessary. Tests are considered if the history suggests a specific cause or another diagnosis.
A limited baseline evaluation commonly includes a complete blood count with differential and ESR and/or CRP. The history and examination guide any additional testing.
In specialist care, total IgE and IgG anti-thyroid peroxidase (anti-TPO) antibodies may help characterise some chronic cases. Further tests are selected according to the findings, not ordered as a broad allergy package.
Carefully selected provocation or threshold testing may help confirm triggers such as cold, pressure or dermographism. Testing should be clinician-directed.
Do I need a complete allergy panel? Usually not for chronic spontaneous hives. Limited investigations may be considered; broad food panels and repeated testing rarely help without a suggestive history.
04 / EVIDENCE-BASED TREATMENT
Stepwise treatment to control hives
The appropriate choice depends on the diagnosis, age, symptoms, medical history and previous treatment response. These are treatment categories, not a self-medication plan.
Modern, second-generation antihistamines
Non-sedating or less-sedating H1 antihistamines are the usual first-line treatment. For chronic urticaria, regular use is often more helpful than repeatedly waiting for a flare.
Doctor-supervised dose adjustment
When standard dosing is insufficient, guidelines allow a clinician to increase a suitable second-generation H1 antihistamine up to fourfold in selected patients. This is usually off-label and must be medically supervised.
Specialist treatment options
Omalizumab may be considered when adequately optimised antihistamines do not control chronic spontaneous urticaria. Suitability, access and monitoring need individual discussion.
Further specialist escalation
For severe refractory cases, clinicians may consider other options, such as ciclosporin with appropriate safety monitoring. These are not routine treatments for everyone.
Avoid relying on repeated steroid courses
Systemic corticosteroids are not recommended for long-term control of chronic urticaria. A short course may sometimes be considered for a severe flare after medical assessment, but ongoing control generally requires another plan.
05 / SIMPLE DAILY STEPS
Practical habits that may reduce discomfort
Try to identify reproducible aggravating factors, but avoid making major lifestyle changes based on guesswork.
Photograph an active flare
Individual wheals may disappear before your appointment. A photo with the time noted can help the diagnosis.
Avoid overheating when relevant
Heat, hot showers or sweating aggravate symptoms for some patients; cooler surroundings may reduce discomfort.
Notice friction and pressure
Scratching, tight clothing or heavy straps can worsen certain inducible types.
Check medicine-related flares
Tell your dermatologist about painkillers and other medicines. Do not stop prescribed medicines without advice.
Keep a simple symptom record
Frequency, itching, swelling and sleep disturbance can help track control; the Urticaria Control Test may be used.
Avoid unsupported restrictions
Routine restrictive diets and broad allergy testing are usually unnecessary without a clear clinical reason.
06 / PATIENT QUESTIONS
Frequently asked questions about hives
Are hives contagious?
No. Urticaria itself does not spread through touch, towels, clothes or shared meals.
What makes urticaria chronic?
Hives, angioedema or both that recur for six weeks or longer meet the time definition of chronic urticaria.
Does chronic urticaria mean I have a food allergy?
Usually not. A true food allergy is considered when symptoms follow a specific exposure promptly and repeatedly, particularly with other allergic symptoms.
Do I need an allergy test or food-intolerance panel?
Not routinely. Testing should be targeted to the medical history. Broad panels often create confusing results without improving care.
Why do wheals disappear and return at another site?
Individual hives typically fade within 24 hours, while new wheals can arise elsewhere as mast-cell activity continues.
Can stress cause or worsen hives?
Stress may worsen symptoms for some patients, but it is not an adequate explanation for every case and does not replace medical assessment.
Are antihistamines safe for long-term use?
Many modern second-generation antihistamines are used long term under a clinician’s guidance. The choice and dose depend on age, other medicines and medical conditions.
Can I take four antihistamine tablets myself?
No. Some guidelines allow up to fourfold dosing of a suitable second-generation antihistamine for selected chronic cases, but this is off-label and should only be done under medical supervision.
Should I take steroids every time hives return?
No. Repeated or prolonged systemic steroid use is not advised for chronic urticaria due to adverse effects. Discuss a safer long-term control plan.
What is the difference between urticaria and angioedema?
Wheals are superficial raised itchy patches; angioedema is deeper swelling. Recurrent angioedema without wheals sometimes needs a different work-up.
What if an individual mark lasts longer than one day?
Painful lesions persisting over 24 hours, especially with bruising or residual pigmentation, require assessment for other conditions such as urticarial vasculitis.
When is swelling an emergency?
Tongue or throat swelling, breathing difficulty, wheezing, faintness or collapse require urgent emergency evaluation because anaphylaxis or airway compromise may be occurring.
