Hives are an itchy, discolored (a change in skin tone) rash that can be slightly raised off of the skin. It is caused when theimmune systemsees a threat and releases histamine from mast cells and basophils in the dermis of theskin. The released histamine causes dilation of the blood vessels and fluid to leak into the skin. This results in skin discoloration and swelling.

Differences Between Welts and HivesWeltsand hives are the two terms that are often used interchangeably but have slightly different meanings. A welt is a discolored, raised area of the skin that occurs from an injury or as an immune reaction. Hives are made up of welts. Hives are red, itchy welts that are always an immune reaction.

How to Keep a Hives Rash From Spreading

To keep hives from spreading it is important to identify and avoid any known triggers. This can prevent future occurrences as well.

Avoid usingaspirin, alcohol, andnonsteroidal anti-inflammatory drugs(NSAIDs), which can worsen symptoms, and should not be used when someone has hives.Also do not scratch hives, as this can make symptoms worse.

Antihistamines

Antihistaminesare used to block the histamine response and are very useful in treating hives. Over-the-counter medications like Claritin (loratadine) and Zyrtec (cetirizine) are typically nonsedating (not producing sleepinees) when used at prescribed doses.

Topical Treatments

The second type of topical cream is hydrocortisone cream. This is a steroid-based cream that reduces swelling and itching.

A cold compress is a nondrug option to reduce the itchiness and swelling from hives. Ice cubes wrapped in a washcloth can provide some relief.

Steroid Medications

For severe cases of hives, a healthcare provider may prescribe an oral steroid medication calledprednisoneor prednisolone to reduce hiveinflammationand itchiness.

These medications need to be taken as directed, and they should not be stopped without first consulting a healthcare provider.

Light Therapy

Phototherapy, also known as light therapy, can be an effective treatment if someone is not responding to other treatments. It is typically done in a healthcare provider’s office a few times per week for several months.

When to Consult a Healthcare Provider

Hives are generally self-limiting and resolve on their own or with simple home treatments. However, for some people hives can become chronic. Hives that appear every day or almost every day for six weeks or longer are consideredchronic hives.If you have chronic hives, contact your healthcare provider for treatment guidance.
