What are the possible causes of itchy blisters on both arms, along with itching on the chest and scalp for the past four days, that have not improved after taking Allegra 180 mg for two days?
Since fexofenadine (Allegra) hasn't brought relief, the cause may not be a simple allergy. Symmetrical blisters on your arms, chest, and scalp could point to a reaction like contact dermatitis, a viral infection, or another inflammatory skin condition. Please try to avoid scratching the blisters to prevent a secondary infection. I highly recommend having a doctor or dermatologist examine these spots in person. They can provide an accurate diagnosis and prescribe targeted treatments, like topical creams, to help you feel much better soon.
