The time it takes for hives to subside quickly varies from person to person, usually ranging from a few hours to a few days, but the exact duration depends on the severity of the condition. It is recommended to promptly identify the triggers and take soothing measures. The following points explain common situations:
1. **Acute attack phase**
If the rash is triggered by a specific factor such as food or medication, some people may experience relief within hours after avoiding the trigger and using anti-allergy medication. However, complete resolution may take one or two days, during which time the rash may recur.
2. **Chronic or recurrent**
If urticaria persists for more than several weeks, it often resolves more slowly. Even if the surface symptoms are relieved after medication, it may recur if the underlying cause is not eliminated, and it is necessary to consult a doctor to find the underlying cause.
3. **Impact of Assistive Care**
Applying cold compresses, wearing loose clothing, and avoiding scratching can help temporarily relieve itching and redness, but these methods mainly reduce discomfort and may not necessarily speed up the complete disappearance of the rash.
In general, the time it takes for urticaria to subside depends on the type of urticaria, individual constitution, and treatment method. If the rash persists or is accompanied by severe symptoms such as difficulty breathing, please seek medical attention immediately. Keep a record of your diet and environmental exposures to help identify triggers, and use medications correctly under the guidance of a doctor to avoid long-term self-medication.
