Find Dermatology SpecialistsFrequently Asked Questions
What causes an allergic rash?
An allergic rash occurs when your skin reacts to a substance your body perceives as harmful, such as pollen, pet dander, latex, certain foods, or medications. The immune system triggers histamine release, causing itching and inflammation.
How long does an allergic rash typically last?
Most allergic rashes resolve within a few hours to several days after removing the trigger. However, severe reactions may persist for 1-2 weeks. If symptoms continue beyond this, consult your doctor.
When should I see a doctor for an allergic rash?
Seek immediate medical attention if you experience difficulty breathing, swelling of the face or throat, or signs of infection. Also see a doctor if the rash doesn't improve within a week or worsens despite home treatment.
