Understanding Urticaria — Pathophysiology, Acute vs. Chronic

Hives (urticaria) affect about 20% of people at some point in their lives. They are one of the most common skin complaints seen in primary care.

Urticaria (hives) — raised red welts on skin from allergic reaction

Hives happen when certain immune cells in the skin release histamine and other chemicals. This causes small blood vessels to leak fluid, creating raised, red, intensely itchy welts. Each welt usually appears, peaks, and fades within 24 hours at a single spot — which sets hives apart from other skin conditions that stay in one place.

Hives are grouped into two types based on how long they last:

Acute hives (less than 6 weeks) — the most common type, often with an identifiable trigger such as foods, medications, insect stings, infections, or physical triggers like cold or exercise
Chronic hives (more than 6 weeks) — harder to pin down. A specific cause is found in fewer than half of cases. Many cases involve the immune system mistakenly activating skin cells on its own.

Common triggers include:

Foods: tree nuts, shellfish, peanuts, eggs, dairy
Medications: NSAIDs (ibuprofen, naproxen), aspirin, ACE inhibitors, penicillin
Viral infections — the most common trigger in everyday practice
Physical factors: cold, heat, pressure, exercise

Our board-certified provider conducts a structured evaluation. This includes reviewing potential triggers, medications, recent illnesses, diet, and any signs of swelling (angioedema). Please photograph your welts before the visit — their appearance helps confirm the diagnosis. The most important first question is whether your hives are occurring alone or with warning signs like throat tightness, lip or tongue swelling, or trouble breathing. Those signs point to anaphylaxis — a life-threatening allergic reaction that needs epinephrine and emergency care, not telehealth.

Common Triggers & Presentations We Evaluate

Food-Triggered Acute Urticaria

Tree nuts, shellfish, peanuts, eggs — wheals within 2 hours of ingestion

Medication-Induced Urticaria

NSAIDs (ibuprofen, naproxen), ACE inhibitors, penicillin-class antibiotics

Viral Infection-Associated Urticaria

Most common trigger — hives during or shortly after a cold, flu, or GI illness

Chronic Spontaneous Urticaria

Daily or near-daily hives >6 weeks; often autoimmune; requires systematic management

Physical Urticaria

Cold urticaria, dermographism, pressure urticaria, cholinergic (exercise-induced)

Stress-Related Urticaria

Stress exacerbates mast cell reactivity; common in chronic urticaria patients

Contact Urticaria

Latex, certain foods on skin, cosmetic ingredients — immediate-type reaction at contact site

Idiopathic Urticaria

No identifiable trigger — requires long-term antihistamine therapy and allergy follow-up

Urticaria Treatment — Antihistamines, Steroids & Chronic Management

The preferred first-line treatment for all types of hives is a non-drowsy daily antihistamine. Good options include:

Cetirizine (Zyrtec) 10 mg daily
Loratadine (Claritin) 10 mg daily
Fexofenadine (Allegra) 180 mg daily

If the standard dose is not enough, guidelines recommend increasing up to 4 times the normal dose before adding other medications. Benadryl (diphenhydramine) can help with severe flares or nighttime itching, but it causes drowsiness and is not ideal for daily long-term use.

When antihistamines alone are not enough:

Short oral steroid course (prednisone 40 mg daily for 3–5 days) — provides fast relief for severe flares. Not for long-term use due to side effects.
Adding famotidine (an H2 blocker) to your daily antihistamine — can boost effectiveness in some patients
Montelukast — may help if your hives are triggered by aspirin or NSAIDs

For chronic hives that do not respond to antihistamines, omalizumab (Xolair) is an FDA-approved monthly injection. It works by blocking IgE, a key player in the allergic response. Xolair requires management by an allergy or skin specialist. Your Innocre provider will identify if you are a candidate and coordinate a referral to the right specialist.

Emergency Warning — Anaphylaxis Requires Epinephrine and 911

Urticaria with any of the following features is anaphylaxis — a life-threatening emergency. Call 911 immediately and use your epinephrine auto-injector (EpiPen) if available:

CALL 911: Throat tightness, difficulty swallowing, sensation of throat closing — upper airway angioedema can rapidly obstruct the airway
CALL 911: Difficulty breathing, wheezing, or stridor — bronchospasm or laryngeal edema
CALL 911: Lip, tongue, or facial swelling (angioedema) especially if rapidly progressing
• Dizziness, lightheadedness, loss of consciousness — anaphylactic shock
• Severe abdominal cramping and vomiting during a suspected allergic reaction
• Do NOT rely on antihistamines or telehealth for anaphylaxis — epinephrine is the only first-line treatment

Hives & Urticaria — Frequently Asked Questions

Yes — migrating, transient wheals are the defining feature of urticaria. Individual hive lesions typically resolve within 24 hours at a single site, but new lesions continue to appear in other locations, giving the appearance of "moving" hives. This behavior distinguishes urticaria from fixed skin conditions like eczema or contact dermatitis. Lesions that remain fixed in one spot for more than 24 hours, or that leave bruising after resolving, may suggest a different condition (urticarial vasculitis) and warrant further evaluation.

Current urticaria guidelines recommend second-generation antihistamines (cetirizine/Zyrtec, loratadine/Claritin, fexofenadine/Allegra) as the preferred first-line treatment. They are equally effective to diphenhydramine (Benadryl) at treating hives but without the sedation, cognitive impairment, and anticholinergic side effects. Benadryl can be used for acute severe breakthrough episodes or nighttime itch relief but is not recommended for routine daily use. For hives not controlled at standard doses, increasing cetirizine to 20mg daily (twice the standard dose) is evidence-based before escalating to steroids.

Hives lasting more than 6 weeks constitute chronic urticaria, and an identifiable cause is found in fewer than half of cases despite thorough investigation. The evaluation for chronic urticaria includes a detailed history for potential triggers, thyroid function testing (autoimmune thyroid disease is associated with CSU), CBC, and consideration of other underlying causes. Many patients with chronic urticaria have an autoimmune mechanism driving mast cell activation. Management focuses on symptom control with daily antihistamines and, if refractory, escalation to omalizumab (Xolair) through an allergist. your provider will initiate this workup and management approach during your visit.

Loratadine (Claritin) and cetirizine (Zyrtec) are considered the preferred antihistamines in pregnancy — both have reassuring safety data. Diphenhydramine (Benadryl) has also been used in pregnancy and is generally considered acceptable in the short term. Fexofenadine (Allegra) has less data. Oral steroids and other systemic agents in pregnancy require careful risk-benefit assessment. your provider will discuss safe options for pregnant patients managing urticaria during your telehealth visit.

If diphenhydramine is not adequately controlling your hives, a step-up approach is appropriate. First, transition to a scheduled second-generation antihistamine (cetirizine 10–20mg daily). If that is insufficient, add an H2 antihistamine (famotidine 20mg twice daily) for synergistic H2-receptor blockade. If still inadequate, updosing cetirizine to 20–40mg daily (off-label, guideline-supported) is appropriate. A short course of oral prednisone may be prescribed for acute severe flares. If hives persist daily despite these measures for weeks, omalizumab referral should be considered. your provider will develop a stepwise, guideline-based plan during your visit.
