Hives, also referred to as urticaria, manifest as itchy, raised welts on the skin, stemming from a myriad of triggers. Allergic reactions stand as a prevalent initiator, although various stimuli contribute. These can encompass allergens like certain foods (such as nuts, milk, and eggs), pet dander, pollen, dust mites, insect bites or stings, and medications, primarily antibiotics, cancer drugs, or ibuprofen. Furthermore, they may arise from infections like strep throat, urinary tract infections, or even viral illnesses like COVID-19.

Medical treatments such as radiation therapy or blood transfusions, along with responses to heat, sweat, cold, stress, sunlight, pressure on the skin, and certain chemicals, all have the potential to provoke hives. Pinpointing and managing chronic hives that persist beyond six weeks pose diagnostic and therapeutic challenges, often revealing underlying health conditions like autoimmune disorders, celiac disease, lupus, type 1 diabetes, rheumatoid arthritis, or thyroid disease. The appearance of hives varies, with welts appearing in shades of red, pink, or flesh-colored, accompanied by sensations of itchiness, stinging, or discomfort. While typically stemming from allergic reactions or environmental factors, hives can also stem from underlying health issues or physical stimuli such as stress, tight clothing, physical activity, or changes in temperature.

What are some symptoms of hives?

Hive symptoms encompass a range of manifestations, including:

  • Itching
  • Red- or skin-colored welts on the skin surface (known as wheals)
  • Rash, often raised and intensely itchy, appears localized on a specific body part
  • Variable-sized raised welts on the skin
  • Intensely itchy reddish welts, particularly bothersome during nighttime
  • Swelling of facial features like the face, eyelids, ears, and mouth, as well as extremities and genital area
  • Asymmetrical swelling on one side of the body
  • Discomfort accompanying localized swelling
  • Changes in skin pigmentation
  • Transient welts that appear and vanish within minutes or hours
  • Angioedema: painful swelling around the eyes, cheeks, or lips
  • Flares triggered by factors like heat, physical activity, or stress
  • Welts exhibit diverse hues, including red, purple, or skin-toned, depending on individual skin coloration
  • Variable-sized welts that shift in shape and appearance, periodically fading and reappearing
  • Intense pruritus (itchiness)
  • Skin sensations of itching, burning, stinging, and warmth
  • Large areas of skin covered by welts
  • Angioedema affecting the lower lip
  • Blanching upon pressing a hive causes temporary disappearance of red or pink coloration
  • Distinct raised spots or patches that may merge together
  • Skin inflammation leads to hot and swollen skin
  • Angioedema characterized by painful swelling lasting 2–3 days rather than itching

These symptoms exhibit varying degrees of severity and duration, with chronic, conversely, potentially persisting beyond six weeks and recurring frequently over extended periods, spanning months or even years.


Conversely, they emerge as itchy, raised welts on the skin, spurred by an array of triggers. Predominantly, allergic reactions to substances such as foods (including nuts, milk, and eggs), pet dander, pollen, dust mites, insect bites or stings, and medications (particularly antibiotics, cancer drugs, or ibuprofen) stand as primary instigators. Moreover, it can be incited by infections like strep throat, urinary tract infections, or even viral illnesses like COVID-19, as well as medical interventions like radiation therapy or blood transfusions. Additional triggers encompass exaggerated responses to temperature fluctuations, stress, sunlight exposure, skin pressure, and contact with specific chemicals or substances. Chronic hives, persisting beyond six weeks, pose diagnostic and therapeutic challenges, potentially linked to underlying health conditions such as autoimmune disorders, celiac disease, lupus, type 1 diabetes, rheumatoid arthritis, or thyroid disorders.

Treatment of hives

Medication Options

The management of hives commonly employs antihistamines, which can be obtained either over the counter or through a prescription. These drugs function by inhibiting the action of histamine, a skin chemical responsible for allergy symptoms like welts. Non-sedating antihistamines are typically preferred to minimize drowsiness. In severe instances, corticosteroids such as prednisone may be administered to alleviate inflammation and itching. In cases where the cause of hives remains elusive, allergists may conduct skin, blood, or urine tests to pinpoint triggers. For refractory chronic hives, medications capable of dampening an overactive immune system, such as cyclosporine, tacrolimus, hydroxychloroquine, and mycophenolate, may be recommended.

Self-Care Strategies

Managing chronic hives involves several self-care measures. These include steering clear of triggers, utilizing nonprescription anti-itch medications, applying cold packs to soothe the skin, taking cool showers or baths, using anti-itch creams or lotions, donning loose-fitting attire, safeguarding the skin from sun exposure, monitoring symptoms, and preparing for healthcare appointments.

Allergic Reaction Management

Identifying and eliminating allergens constitute the optimal treatment for hives triggered by allergic reactions. If the trigger remains unidentified, the condition is termed chronic idiopathic urticaria.

Emergency Situations

In severe instances of hives involving tongue or lip swelling or breathing difficulties, an epinephrine (adrenaline) auto-injector may be prescribed for emergency use. These symptoms could indicate the onset of anaphylaxis, a life-threatening allergic reaction that compromises breathing and can induce shock. Epinephrine remains the sole treatment for anaphylaxis.

Hive treatment encompasses the use of antihistamines, corticosteroids, and trigger avoidance. Severe cases may necessitate the use of an epinephrine auto-injector. Self-care strategies and symptom monitoring play crucial roles in managing chronic hives.

How long hives usually last?

Urticaria represent a distinctive form of skin eruption marked by swollen, itchy, red welts. Their duration can widely fluctuate, typically with individual welts subsiding within 24 hours. However, as one set fades, new hives may emerge, extending the overall symptom duration.

Acute hives, lasting up to six weeks, often stem from specific triggers like infections, dietary elements, medications, insect bites, transfusions, or allergens. Generally, resolution of the underlying cause results in the disappearance of hives.

In contrast, chronic hives persist beyond six weeks. Despite extensive testing, the root cause often remains elusive. Approximately half of chronic hive cases involve antibodies targeting mast cells, prompting the release of histamine and other chemicals, inducing hives and itching. While linked to autoimmune disorders, addressing the underlying condition doesn’t necessarily alleviate hives.

Physical urticaria arises from various “physical” stimuli such as scratching, pressure, exposure to temperature extremes, sunlight, or vibrations. Cold urticaria, cholinergic urticaria, and sun-induced urticaria exemplify this category, often manifesting within minutes of exposure to the triggering factor.

Hives vs rash

Hives, or urticaria, and rashes represent distinct skin conditions, each with unique characteristics. Urticaria manifest as raised, itchy bumps that can exhibit shades of red or flesh tones, varying in size and configuration. They may emerge sporadically across the body or localize to specific areas, with durations ranging from fleeting to prolonged.

Rashes provoke alterations in skin color or texture, encompassing manifestations such as itchy bumps, roughness, scaliness, or cracking. While some rashes elicit itchiness, others may induce pain or discomfort. Unlike urticaria, rashes are not universally red and may present with diverse features like scaliness, roughness, or the presence of blisters or welts. Hives typically maintain a smooth texture and do not induce dryness, peeling, or flaking, distinguishing them from certain rashes like dermatitis or heat rash. Both urticaria and rashes can be incited by a myriad of factors, including allergies, irritants, infections, or immune system dysregulation. Seeking medical attention is imperative if severe symptoms such as difficulty breathing, swelling, or intense pain arise, as these could signify a grave allergic reaction or underlying medical condition.
