What Should You Eat If You Have Urticaria?

Generally, patients with urticaria may consume foods such as carrots, grapes, apples, mung beans, and chicken. They may also take medications—including loratadine capsules, cetirizine hydrochloride tablets, ebastine tablets, montelukast sodium tablets, and prednisone tablets—as prescribed by their physician. A detailed analysis follows:

I. Foods

1. Carrots

Rich in beta-carotene, vitamins, and other nutrients, carrots promote spleen and stomach health and clear heat and toxins. They help enhance immune function and rarely trigger allergic reactions, making them suitable for patients with urticaria.

2. Grapes

Abundant in vitamin C and flavonoids—potent antioxidants—grapes reduce vascular permeability and exudation, thereby helping alleviate skin pruritus and edema associated with urticaria.

3. Apples

A common mild fruit, apples are rich in pectin and other dietary fibers that help regulate intestinal flora and facilitate toxin elimination. They seldom provoke allergic reactions and are appropriate for daily consumption by urticaria patients.

4. Mung Beans

Mung beans possess heat-clearing, detoxifying, summer-heat-relieving, and diuretic properties. Prepared as mung bean soup, they assist in eliminating damp-heat from the body and offer dietary therapeutic benefits for urticaria triggered by damp-heat or similar factors.

5. Chicken

An excellent source of high-quality protein, chicken has relatively low allergenicity compared with other meats. Moderate intake helps replenish essential nutrients and strengthen physical constitution. Cooking methods should be light—for example, steaming or boiling—to minimize potential irritants.

II. Medications

1. Loratadine Capsules

A commonly used second-generation antihistamine, loratadine selectively blocks peripheral H₁ receptors, effectively relieving urticaria-related symptoms such as pruritus and wheals. It offers rapid onset, prolonged duration of action, and a relatively low incidence of adverse effects like sedation.

2. Cetirizine Hydrochloride Tablets

Also a second-generation antihistamine, cetirizine suppresses histamine-mediated allergic reactions and demonstrates marked efficacy in treating urticaria. It stabilizes mast cells and reduces the release of inflammatory mediators, thereby alleviating allergic symptoms affecting the skin and mucosa.

3. Ebastine Tablets

Ebastine exhibits potent and long-lasting antihistaminic activity and inhibits the release of inflammatory mediators such as leukotrienes. It is particularly suitable for patients with chronic urticaria or those with comorbid allergic rhinitis, effectively controlling symptoms and improving quality of life.

4. Montelukast Sodium Tablets

A leukotriene receptor antagonist, montelukast sodium exerts anti-inflammatory and anti-allergic effects by blocking the binding of leukotrienes to their respective receptors. In patients with urticaria who respond poorly to conventional antihistamines—or who present concurrent respiratory symptoms—combination therapy with montelukast sodium may yield superior clinical outcomes.

5. Prednisone Tablets

A glucocorticoid with potent anti-inflammatory and anti-allergic properties, prednisone is typically reserved for severe cases of urticaria—such as those complicated by laryngeal edema—or for patients unresponsive to standard treatment. However, long-term use may cause multiple adverse effects—including osteoporosis and hyperglycemia—and thus must be strictly guided by physician instructions and avoided for prolonged periods.

Patients with urticaria should choose bland, easily digestible, and low-allergenic foods while avoiding spicy, irritating, or highly allergenic items to prevent symptom exacerbation. Regarding pharmacotherapy, drug selection should be individualized according to disease severity and patient-specific factors, under strict medical supervision; self-medication or indiscriminate use of drugs must be avoided.
