For rapid relief of urticaria, oral antihistamines are often considered, but specific medication should be chosen under the guidance of a doctor. The following are medication recommendations for common situations:

1. **Commonly used antihistamines:** such as loratadine and cetirizine. These medications can help relieve itching and wheals, and generally work quickly, making them suitable for mild to moderate symptoms.

2. **Adjustments for different symptoms**: If there is significant redness or discomfort, the doctor may recommend the combined use of other types of medications, but do not mix them on your own.
3. **Pay attention to medication safety:** Some medications may cause drowsiness. Avoid driving or working at heights while taking these medications. Pregnant women, children, and other special groups must strictly follow their doctor's instructions.
In summary, medication effectiveness varies from person to person, and it is recommended to consult a doctor to determine the cause of the illness. In daily life, keeping a record of allergens, wearing loose clothing, and maintaining skin cleanliness can help reduce flare-ups. If symptoms do not improve or worsen after medication, please return for a follow-up appointment to adjust the treatment plan.
