Drug-induced urticaria

Drug-induced urticaria (pronunciation: /ˌɜːrtɪˈkeɪriə/), also known as drug-induced hives, is a type of urticaria or hives that occurs as a reaction to certain medications.

Etymology

The term "urticaria" comes from the Latin urtica, meaning "nettle", and the suffix -aria, meaning "pertaining to". The term "drug-induced" refers to a condition that is caused or triggered by a drug or medication.

Definition

Drug-induced urticaria is a type of allergic reaction that occurs when a person's immune system reacts to a drug or medication. This reaction causes the release of histamine and other chemicals in the body, leading to the development of hives. Hives are red, itchy welts that can appear anywhere on the skin.

Causes

Any drug or medication can potentially cause drug-induced urticaria, but some are more likely to cause this reaction than others. These include antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and certain blood pressure medications.

Symptoms

The main symptom of drug-induced urticaria is the appearance of hives on the skin. These hives can vary in size and shape, and they can appear anywhere on the body. Other symptoms can include itching, burning, and swelling of the skin.

Treatment

Treatment for drug-induced urticaria involves discontinuing the drug or medication that caused the reaction and treating the symptoms. This can include taking antihistamines to reduce itching and swelling, and using corticosteroids to reduce inflammation.
