The best treatments for urticaria (hives) depend on the severity and cause. Antihistamines are the first-line treatment to relieve itching and reduce swelling. In more severe or chronic cases, corticosteroids or immune-modulating drugs may be prescribed. Avoiding known triggers like allergens or certain foods is crucial. For acute cases related to infections, antibiotics like ceftriaxone may be used. A ceftriaxone injection wholesaler can supply the antibiotic when needed for bacterial triggers. Always consult a healthcare provider to determine the underlying cause and appropriate treatment plan for urticaria, especially if symptoms persist or worsen over time.
