Lip Hives: Swelling, Allergic Reactions and When to Act
Hives on the lips often involve deeper swelling, called angioedema. Because swelling can spread to the tongue and throat, it is important to know what to watch for.
Common Causes of Hives on Lips
- Food allergy, including oral allergy syndrome
- Medication reactions
- Lip products, toothpaste or dental materials
- Insect stings
- Hereditary or ACE inhibitor angioedema. See angioedema of the lips
Watch for Spreading Swelling
Swelling that extends to the tongue or throat, or comes with voice changes, wheeze or dizziness, needs emergency care.
Relief and Self-Care
- Stop using suspect products
- Apply a cool compress
- Take a non-sedating antihistamine if symptoms are mild
- Contact a doctor promptly
When to Call 911
Call 911 right away if hives or swelling occur with difficulty breathing or swallowing, a tight or closing throat, a swollen tongue, lips or face, wheezing, faintness, or a sudden feeling of impending doom. Use an epinephrine auto-injector first if one has been prescribed to you, then call for emergency help.
When to See a Doctor
See a doctor if your symptoms last more than a few days, keep coming back, cover large areas, or interfere with sleep or daily life. Dr. Tiffany Young’s Hives Treatment Center in San Francisco offers online and in-person consultations for patients with hives on the lips.
