From the Research
Seasonal hives, also known as seasonal urticaria, are itchy, raised welts on the skin that appear in response to specific seasonal triggers, and the most effective treatment is daily antihistamines, such as cetirizine (Zyrtec) 10mg daily, loratadine (Claritin) 10mg daily, or fexofenadine (Allegra) 180mg daily, as recommended by the most recent expert consensus 1.
Definition and Causes
Seasonal hives typically occur during certain times of the year when allergens like pollen, mold spores, or insect bites are more prevalent.
- They are characterized by itchy, raised welts on the skin that can appear anywhere on the body.
- The exact cause of seasonal hives is often unknown, but they are thought to be triggered by an allergic reaction to seasonal allergens.
Treatment Options
Treatment options for seasonal hives include:
- Over-the-counter antihistamines, such as cetirizine (Zyrtec) 10mg daily, loratadine (Claritin) 10mg daily, or fexofenadine (Allegra) 180mg daily, which can help relieve symptoms 2.
- For more severe cases, a doctor might prescribe stronger antihistamines or a short course of oral corticosteroids like prednisone 3.
- Identifying and avoiding specific triggers is crucial for prevention, and keeping a diary of when hives appear can help identify patterns related to seasonal changes.
Prevention
Prevention measures for seasonal hives include:
- Wearing protective clothing, such as long sleeves and pants, when outdoors during high pollen seasons.
- Using air purifiers to reduce exposure to allergens.
- Showering after outdoor activities to remove allergens from the skin.
- Avoiding outdoor activities during peak pollen hours, usually between 5am and 10am.
Quality of Life
Seasonal hives can significantly impact quality of life, causing discomfort, anxiety, and stress.
