hours to a couple of days. Symptoms such as sneezing, irritated eyes, and rash can subside relatively quickly with the help of over-the-counter antihistamines and other allergy treatments.   Moderate to severe allergic reactions often last longer, typically several days to a week. These reactions involve more pronounced symptoms, such as persistent itching, swelling, or respiratory difficulties. Medical intervention, including prescription medications, may be needed to manage these symptoms effectively and alleviate your discomfort.   It's critical to remember that if you experience a severe allergic reaction known as anaphylaxis, it’s considered a medical emergency that requires urgent attention. Anaphylaxis can progress rapidly and become life-threatening if not treated promptly. For more information, contact us today or schedule an appointment online.
