How long do hives usually last in adults? That is a question I hear from time to time. When someone comes into the clinic with hives, one of the first questions my allergist will ask me is how long have they been there?
This guide will help you determine how long a hive can last in adults. This, of course, varies by the severity of the episode, what causes them, and at what time of year they occur. The more severe the case is, the shorter the duration of a hive attack tends to be. While hives (also called urticaria) are usually self-limited, they can last several weeks during which time sufferers may need medical intervention.
How Long Do Hives Last in Adults?
The duration of hives can vary widely between individuals, as well as within the same person. The average length of a hive is about two weeks, but it’s not unusual for them to last up to six weeks.
Hives can be triggered by several things: allergies, stress, infections (like strep throat or pneumonia), and physical activity (like exercise). They’re also linked to some medicines and other chemicals you may use every day, for example, some medicines used for high blood pressure (hypertension) can cause hives. Some people get hives from eating shellfish or fish like tuna. Many different types of animals have been known to cause hives in people who are sensitive to the most common cats, dogs, and horses.
The length of time that hives last depends on the cause of the hives, as well as what type of hives you are experiencing. The most common type of hives is called urticaria, which is caused by an allergic reaction. These types of hives tend to be short-lived and can usually be treated with antihistamines or steroids.
In some cases, however, hives can become chronic and last for months or years at a time. These types of hives may be caused by other underlying issues such as stress or autoimmune disorders.
