For most people, hives typically last a few days to a few weeks and go away on their own.
If your hives last longer than 6 weeks, you may have chronic hives. In this case, it may be helpful to speak with a board certified dermatologist to identify suitable treatment options.
The American Academy of Dermatology notes that the goal of treating hives is to:
- manage the itching
- prevent new hives from forming
- avoid any known triggers
A dermatologist may suggest taking antihistamines or applying anti-itch lotions or creams.
- applying a cool compress or ice pack to the affected area
- wearing loose-fitting and lightweight clothes
- taking a cool bath or shower
- wearing sunscreen and protective clothing when going out into the sun to avoid sun damage
It isn’t always possible to prevent hives. However, it can be helpful to identify what may be triggering them so you know what to avoid.
Common triggers of hives include:
- certain foods, such as peanuts and shellfish
- latex
- pet dander
- pollen
- insect bites
- certain medications, such as antibiotics and ibuprofen
- viral infections, such as a cold or hepatitis
It can be beneficial to keep an allergy diary to note potential triggers whenever you get hives. This can include foods you’ve eaten that day, additional symptoms you’re experiencing, and any medications you’re taking.
If you frequently experience hives, you can show your diary to a healthcare professional, such as a dermatologist, to help identify potential triggers and treatment options.
Mild hives typically aren’t serious and should go away on their own. However, you should seek medical support if you have hives and:
- you find it difficult to breathe or your throat feels tight
- you feel confused
- you feel drowsy or dizzy
- your skin, tongue, or lips turn pale — if you have dark skin, this may be easier to spot on the palms of your hands or soles of your feet
- you have facial swelling
- you are vomiting
These may be signs of a severe allergic reaction, also known as anaphylaxis, which requires immediate medical attention.
