Hives in older adults

Overview

Hives (also called urticaria) are raised, itchy welts on the skin. They can appear suddenly and usually go away within a few hours, but some people get hives that last longer.

Yes, hives are common in people of all ages, including older adults. Many adults experience hives at some point.

Hives can affect anyone, but older adults may be more susceptible if they take multiple medications or have chronic health issues.

Symptoms

Common symptoms

• Itchy, raised welts (wheals) on the skin
• Welts that are red, pink, or skin-colored
• Welts that can vary in size and shape
• Welts that may come and go quickly

Symptoms in children

• Often appear after infections or food reactions
• May be accompanied by fever or other symptoms

Symptoms in older adults

• Often triggered by medications (e.g., antibiotics, pain relievers)
• May last longer or come back frequently
• Sometimes related to autoimmune conditions

Causes

Main causes

• Allergic reactions to foods, medications, insect stings, or latex
• Infections (viral, bacterial, or fungal)
• Physical triggers (pressure, cold, heat, sunlight, exercise)
• Stress or emotional upset
• Autoimmune conditions (when the immune system mistakenly attacks the body)

Risk factors

• Taking multiple medications (prescription or over-the-counter)
• Having chronic health conditions like thyroid disease or lupus
• Stress or anxiety
• Being exposed to new foods or environments

When to see a doctor

See a doctor urgently if:

• If you have trouble breathing or swelling in your face or throat
• If hives are accompanied by dizziness or fainting
• If you have a high fever with hives

Book a routine appointment if:

• If hives last more than a few days or keep coming back
• If you are not sure what caused them
• If your sleep or daily life is affected by itching

Diagnosis

Your doctor will ask about your symptoms, health history, and any new medications or foods. They will also examine your skin.

Tests that may be done

• Allergy testing (skin prick tests or blood tests) to find triggers
• Blood tests to check for autoimmune conditions or infections
• Sometimes a skin biopsy (taking a small sample of skin) if the cause is unclear

What to expect at your appointment

The doctor may ask you to keep a diary of your hives, including what you ate or did before they appeared. This helps identify triggers.

Treatment

Treatment focuses on relieving itching and avoiding triggers. Many cases get better on their own or with simple home care.

Self-care at home

• Apply a cool, wet cloth to the itchy areas
• Take lukewarm baths with colloidal oatmeal or baking soda
• Wear loose, soft clothing to avoid irritating the skin
• Avoid hot showers, tight clothes, and scratching

Medical treatments

Doctors often recommend antihistamines (medicines that reduce allergy symptoms) taken by mouth. For more severe or long-lasting hives, they may prescribe other medications such as steroids or immune-modulating drugs. Always talk to your doctor before starting any new medication.

When is surgery considered?

Surgery is not used for hives. If an underlying condition causes hives, that condition may need treatment, but surgery is not a direct treatment for hives.

Living with this condition

Living with hives can be uncomfortable because of itchiness. But most people manage well by avoiding triggers and using simple cooling methods.

Lifestyle tips

• Keep a diary to track what triggers your hives
• Manage stress with relaxation techniques like deep breathing or meditation
• Stay cool and avoid overheating
• Use fragrance-free soaps and lotions

Diet and exercise

Some people find that certain foods cause hives. But most cases are not related to diet. Gentle exercise is fine, but avoid heavy sweating if it triggers hives.

Mental health and emotional wellbeing

Constant itching can be frustrating and may affect sleep or mood. It is normal to feel stressed or anxious. Talk to your doctor if it affects your quality of life.

Prevention

You can reduce the chance of getting hives by avoiding known triggers. If you have a history of hives, talk to your doctor about what to avoid.

Vaccines

There is no vaccine for hives. Vaccines for other diseases are safe for most people with hives, but let your doctor know about your skin condition.

Screening programmes

Routine screening is not needed. If you have chronic hives, your doctor may do tests to rule out other conditions.

Complications

If left untreated

• Chronic hives (lasting more than 6 weeks) that can be more difficult to treat
• Angioedema — deeper swelling of the face, lips, or throat that can be serious
• Sleep problems and stress due to constant itching

Long-term outlook

Most hives clear up quickly and are not dangerous. Even chronic hives often improve with treatment and a healthy lifestyle. With your doctor’s help, you can manage symptoms and feel better.
