FAQ - Hives and Urticaria

Urticaria, commonly known as hives, is an allergic skin reaction characterised by red patches, swelling, and intense itching. It can be classified as acute (lasting less than six weeks) or chronic (persisting for over six weeks).

Symptoms include:

• Red patches or raised welts on the skin.
• Intense itching, which may worsen with heat or stress.

Lesions that appear and disappear across different areas of the body.

The itching associated with hives is caused by histamine, a chemical released by the immune system. It stimulates nerve endings in the skin and exacerbates inflammation, leading to discomfort.

Yes, hives can appear on any part of the body, but they are more commonly found on areas exposed to allergens or friction, such as the face, neck, or torso.

Common triggers include:

• Food allergies (e.g., shellfish, nuts, milk).
• Insect bites.
• Medications.
• Environmental factors such as heat, cold, or sunlight.

Viral or bacterial infections.

Heat and stress can increase blood flow and histamine release, which exacerbate itching and inflammation associated with hives.

Shellfish, nuts, milk, eggs, and food additives like preservatives or colourings are common triggers.

Yes, stress is a common trigger as it heightens the body's inflammatory response. Relaxation techniques such as meditation or engaging in hobbies can help reduce stress-related flare-ups.

Keeping a diary to track foods, activities, or environmental exposures before flare-ups can help identify triggers. Common culprits include pollen, dust, perfumes, or even stress.

• Hives: Raised red welts with intense itching, often appearing and disappearing quickly.
• Rashes: General skin inflammation with redness, peeling, or small blisters, which tend to last longer.

Eczema: A chronic condition with dry, itchy, and cracked skin, often triggered by allergies or stress.

Angioedema is a deeper swelling of the skin, often affecting areas like the lips, eyelids, or throat. It may occur alongside hives and can cause discomfort or breathing difficulties in severe cases.

In rare cases, chronic hives can indicate an underlying autoimmune disorder or other health issues. Persistent or severe symptoms should be evaluated by a healthcare professional.

Treatment options include:

• Antihistamines, such as Histallay, which block histamine receptors to reduce symptoms without causing drowsiness.
• Corticosteroids for severe cases.

Avoidance of identified triggers.

Yes, antihistamines are the first-line treatment for hives. Non-drowsy options such as Histallay effectively block histamine action, alleviating symptoms while allowing individuals to maintain their daily routines.

Yes, regular use of antihistamines, such as Histallay, can help prevent flare-ups in individuals prone to hives by blocking histamine receptors before symptoms develop.

If antihistamines are ineffective, consult a doctor. They may recommend higher doses, alternative medications such as corticosteroids, or investigate underlying causes like autoimmune disorders.

In some cases, doctors may combine antihistamines with other treatments like corticosteroids or immunomodulators. Always consult a healthcare provider before combining medications.

• Keep your skin hydrated with fragrance-free lotions.
• Avoid hot baths; opt for lukewarm water instead.
• Wear loose, lightweight cotton clothing.

Apply cool compresses to affected areas.

Acute hives usually resolve within hours to days, while chronic hives persist for over six weeks.

Preventative measures include:

• Identifying and avoiding triggers.
• Maintaining a stress-free lifestyle.
• Keeping the skin hydrated with fragrance-free products.

Using antihistamines as prescribed.

• Keep your living spaces clean and well-ventilated.
• Avoid harsh chemicals found in cleaning products or detergents.

Maintain a comfortable temperature, avoiding extremes of heat or cold.

Yes, exercise can induce hives in some individuals, especially when combined with other triggers like heat or specific foods.

Seek medical attention if:

• Symptoms persist for more than a week.
• Swelling occurs in areas such as the face, lips, or throat.

Symptoms are severe or interfere with breathing.

If your hives appear shortly after exposure to specific foods, medications, or environmental factors, they are likely related to an allergy. Allergy testing can confirm the trigger.

Chronic urticaria can often be managed but not always cured, especially when the cause is idiopathic. Lifestyle changes and antihistamines may help reduce the frequency and severity of symptoms.

Effective strategies include:

• Keeping a detailed diary to track triggers.
• Using non-drowsy antihistamines such as Histallay.
• Managing stress through relaxation techniques.

Consulting a doctor for specialised treatments when needed.
