How should I manage a patient with bright red, inflamed, burning lips suggestive of cold‑induced urticaria?

Management of Bright Red, Inflamed, Burning Lips

Critical Clarification: This is NOT Cold-Induced Urticaria

The presentation of bright red, inflamed, burning lips does not match cold-induced urticaria, which manifests as hives (wheals) and angioedema triggered by cold exposure—not persistent lip inflammation. 1, 2 Cold urticaria presents with localized or systemic papules/wheals that develop within 3-5 minutes of cold contact and resolve when rewarming occurs. 1, 3

Likely Differential Diagnosis

Your patient's symptoms suggest:

• Cheilitis (lip inflammation) - which can be allergic contact, irritant, angular, or actinic in nature
• Allergic contact dermatitis to lip products, foods, or dental materials
• Irritant contact dermatitis from lip licking, drooling, or harsh products
• Angular cheilitis if inflammation extends to lip corners
• Atopic cheilitis in patients with atopic history

Immediate Management Approach

First-Line Treatment

Stop all potential irritants and allergens immediately, including lip products, toothpaste, mouthwash, and chewing gum. 4

• Apply bland emollients (petroleum jelly, plain lip balm without fragrances or additives) frequently throughout the day 5
• Use cooling antipruritic lotions such as calamine or 1% menthol in aqueous cream for symptomatic relief of burning 4, 6
• Avoid aggravating factors including overheating, stress, alcohol, aspirin, NSAIDs, and codeine 4, 7, 6

If Allergic Component Suspected

Start a second-generation non-sedating H1 antihistamine as first-line therapy:

• Cetirizine 10 mg daily (reaches maximum concentration fastest for rapid symptom relief) 7, 6
• Alternative options: fexofenadine 180 mg, desloratadine 5 mg, or levocetirizine 5 mg daily 6, 5
• Offer at least two different antihistamines to trial, as individual responses vary 7, 6

Dose Escalation if Inadequate Response After 2-4 Weeks

Increase antihistamine dose up to 4 times the standard dose before adding other therapies 7, 6, 5

• Example: Cetirizine can be increased to 40 mg daily 6

What This is NOT

This presentation does NOT warrant:

• Ice cube testing (used only for diagnosing cold-induced urticaria) 1, 2
• Epinephrine auto-injector prescription (reserved for patients with history of anaphylaxis from cold exposure during aquatic activities) 1, 8
• Omalizumab or cyclosporine (reserved for chronic spontaneous urticaria unresponsive to high-dose antihistamines) 7, 6, 5

Critical Pitfalls to Avoid

• Do not use systemic corticosteroids for chronic management—only short 3-10 day courses for severe acute flares 6, 5
• Do not use first-generation sedating antihistamines as first-line therapy due to sedation and cognitive impairment without superior efficacy 5
• NSAIDs should be avoided in aspirin-sensitive patients with any urticarial condition 4, 7, 6

When to Escalate Workup

If symptoms persist despite conservative management and antihistamines:

• Consider patch testing for allergic contact dermatitis to identify specific allergens 4
• Evaluate for nutritional deficiencies (iron, B vitamins, zinc) that can cause angular cheilitis
• Consider fungal or bacterial culture if angular involvement or crusting present
• Rule out systemic conditions (inflammatory bowel disease, lupus) if other systemic symptoms present 4
