What is a permanent treatment for hives on my face triggered by cold temperatures, which started after an allergic reaction to aspirin and did not go away after taking Allegra for 15 days?
What you are experiencing sounds like cold urticaria, which can sometimes be triggered after an allergic reaction like your aspirin event. While there is no instant 'permanent' cure, these hives often resolve on their own over time. Since fexofenadine (Allegra) has not worked, the next best step is seeing an allergist. They can safely adjust your antihistamine dosage or discuss prescription options to block these reactions. In the meantime, try to keep your face warm and protected from cold winds.
