Urticaria, commonly known as hives, is a skin condition characterized by the appearance of itchy, red, and raised welts on the skin. It can be acute or chronic and can significantly impact a person’s quality of life. The treatment of urticaria aims to relieve symptoms, reduce inflammation, and prevent recurrence. In this article, we will explore the most effective treatment options available.
Antihistamines: The First Line of Defense
Antihistamines are the most commonly prescribed treatment for urticaria. They work by blocking the action of histamine, a chemical released during an allergic reaction that causes itching, redness, and swelling.
First-generation antihistamines
These include medications such as diphenhydramine (Benadryl) and chlorpheniramine. They are effective in relieving itching and reducing the appearance of hives. However, they often cause drowsiness as a side effect. For example, a person taking diphenhydramine may feel extremely sleepy and have difficulty concentrating, which can affect their daily activities. These medications are usually best taken at night when the sedative effect may be beneficial for sleep.
Second-generation antihistamines
Examples include loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra). These drugs are less likely to cause drowsiness compared to first-generation antihistamines. They are generally well-tolerated and can be taken once or twice a day depending on the specific product. For instance, loratadine is typically taken once a day, while cetirizine may be taken either once or twice a day.
Second-generation antihistamines are often preferred for long-term use as they do not interfere with a person’s ability to function during the day.
In some cases, a combination of first-generation and second-generation antihistamines may be prescribed. This may be necessary when the urticaria is severe or not responding well to a single antihistamine. For example, a doctor may prescribe a second-generation antihistamine for daytime use to control symptoms and a first-generation antihistamine at night to help with itching and promote sleep.
Corticosteroids: For More Severe Cases
Corticosteroids may be prescribed when antihistamines alone are not sufficient to control urticaria. They work by suppressing the immune system and reducing inflammation.
Oral corticosteroids
Prednisone is a commonly used oral corticosteroid for urticaria. It is usually given in a short course, typically starting with a higher dose and then gradually tapering off. The length of treatment depends on the severity of the urticaria. For example, if the urticaria is very severe, a patient may be prescribed prednisone for a week or two. However, oral corticosteroids can have significant side effects, including increased appetite, weight gain, mood changes, and an increased risk of infections. A patient taking prednisone may notice an increase in their appetite and need to be careful about their diet to avoid excessive weight gain.

A patient taking prednisone may notice an increase in their appetite and need to be careful about their diet to avoid excessive weight gain.
Topical corticosteroids
These are creams or ointments that are applied directly to the skin. They can be useful for localized urticaria or in combination with oral medications. Topical corticosteroids can help reduce itching and inflammation in the affected area. However, they are generally not as effective as oral corticosteroids for widespread urticaria. For example, if a patient has urticaria only on a small area of the body, a topical corticosteroid may be sufficient to relieve symptoms.
Immunomodulators: For Chronic and Refractory Cases
In chronic and refractory cases of urticaria, immunomodulators may be considered. These medications work by modulating the immune system to reduce the allergic response.
Omalizumab
Omalizumab is an immunomodulator that has been shown to be effective in treating chronic idiopathic urticaria. It works by binding to immunoglobulin E (IgE), thereby reducing the allergic response. It is usually given as an injection once a month or every few weeks depending on the patient’s condition. However, it is an expensive treatment option and may not be covered by all insurance plans.
Cyclosporine
Cyclosporine is another immunomodulator that may be used in severe and chronic cases of urticaria. It suppresses the immune system more strongly than corticosteroids. However, it has significant side effects, including potential damage to the kidneys and liver. Regular blood tests are required to monitor the function of these organs when a patient is taking cyclosporine.
Lifestyle Modifications: An Important Adjunct
In addition to medications, lifestyle modifications can play an important role in the treatment of urticaria.
Identify and avoid triggers
The first step is to identify the triggers that cause urticaria. These can include certain foods, medications, environmental factors (such as pollen, dust mites, or animal dander), and stress. Once the triggers are identified, every effort should be made to avoid them. For example, if a person discovers that they are allergic to shellfish and eating shellfish causes urticaria, they should avoid consuming shellfish.
Manage stress
Stress can exacerbate urticaria. Therefore, it is important to manage stress through relaxation techniques such as meditation, yoga, or deep breathing exercises. These techniques can help reduce the body’s stress response and may improve the symptoms of urticaria.
Keep the skin clean and moisturized
Keeping the skin clean and moisturized can help prevent irritation and reduce itching. Use a mild soap and moisturizer regularly. For example, a person with urticaria should avoid using harsh soaps that can further irritate the skin and instead use a gentle, hypoallergenic soap.
Conclusion
In conclusion, the most effective treatment for urticaria depends on the type (acute or chronic), severity, and underlying cause of the condition. Antihistamines are usually the first line of treatment, with second-generation antihistamines being preferred for most cases. Corticosteroids may be added for more severe cases, and immunomodulators may be considered for chronic and refractory cases. Lifestyle modifications are also an important adjunct to treatment. It is important for patients to work closely with their doctors to develop a personalized treatment plan that addresses their specific needs and helps them achieve the best possible outcome.
