What Is Urticaria?
6. How Long Will Urticaria Last?
When patients are given a diagnosis of urticaria, one of the first things they want to know is when the rash will disappear. Unfortunately, the answer varies. For some patients, hives only last a few days or a few weeks. Other people may suffer outbreaks for months or even years. The primary determiner of the timeline is the specific form of urticaria and whether a trigger can be identified.
If you and your allergist have figured out the cause of your symptoms, then avoiding those triggers should eliminate the body’s reaction. However, if you experience chronic hives or chronic idiopathic urticaria, then your symptoms will need to be managed with medications. Also, further testing may indicate another underlying condition, such as thyroid disease, which may be making hives worse.
