  The duration of shellfish allergy symptoms varies based on the severity of the reaction and the treatment received. Here is a breakdown of how long different symptoms typically last: Mild Reactions (Hives, Skin Itching, Mild Gastrointestinal Symptoms): Mild symptoms like hives, skin redness, and mild gastrointestinal distress usually appear quickly after consuming shellfish—often within minutes to an hour. These symptoms typically resolve within a few hours to 24 hours, especially if treated with over-the-counter antihistamines. However, in some cases, hives and itching can last for up to 48 hours before completely subsiding. Moderate Reactions (Swelling, Respiratory Issues, Vomiting): Symptoms such as swelling, vomiting, or difficulty breathing may last longer, especially if the reaction is moderate in severity. Swelling (angioedema) of the lips, throat, or face may take 24 to 48 hours to fully resolve, even with medication. Respiratory symptoms, such as wheezing or coughing, can persist for a day or two, particularly if the reaction affects the airways. Severe Reactions (Anaphylaxis): Anaphylaxis is a life-threatening condition that requires immediate medical intervention, typically with the administration of epinephrine (such as an EpiPen). Once treated, the acute symptoms of anaphylaxis usually resolve within 30 minutes to a few hours. However, in some cases, a second wave of symptoms known as biphasic anaphylaxis can occur hours after the initial reaction, sometimes up to 12 hours later. For this reason, individuals who experience anaphylaxis should be monitored in a medical setting for 4 to 6 hours after the initial treatment. Delayed Reactions: Some people may experience delayed allergic reactions to shellfish, particularly involving gastrointestinal symptoms such as nausea, cramps, or diarrhea. These delayed symptoms can appear several hours after consuming shellfish and may last for up to 48 hours.

  The reported estimate of prevalence of occupational asthma in shellfish-processing workers is 2-36%. […] Exposure by skin contact occurs more in occupational settings and the manifestations are commonly cutaneous in the form of urticaria or allergic contact dermatitis, although occasionally it can be systemic. The prevalence of occupational contact dermatitis to shellfish ranged from 3 to 11%. […] In general, management of any food allergy is basically strict avoidance based on proven clinical reactions and not mere sensitization. Because of cross-reactivity, avoidance of all crustacea is generally advised. Avoidance of mollusks is not necessary unless the patient is concomitantly allergic to it. Since cross-reactivity among crustacea is not complete, it is possible that allergy be limited to certain crustacea members. Patients should be alerted to possible inadvertent hidden exposure to the offending food, particularly in restaurants where cooking equipment or serving utensils may be used for different foods.

• #68 How Long Do Shellfish Allergy Symptoms Last? A Complete Guide

  https://www.lafoodallergy.com/learn/how-long-do-shellfish-allergy-symptoms-last-a-complete-guide

  The duration of shellfish allergy symptoms varies based on the severity of the reaction and the treatment received. Here is a breakdown of how long different symptoms typically last: Mild Reactions (Hives, Skin Itching, Mild Gastrointestinal Symptoms): Mild symptoms like hives, skin redness, and mild gastrointestinal distress usually appear quickly after consuming shellfish—often within minutes to an hour. These symptoms typically resolve within a few hours to 24 hours, especially if treated with over-the-counter antihistamines. However, in some cases, hives and itching can last for up to 48 hours before completely subsiding. Moderate Reactions (Swelling, Respiratory Issues, Vomiting): Symptoms such as swelling, vomiting, or difficulty breathing may last longer, especially if the reaction is moderate in severity. Swelling (angioedema) of the lips, throat, or face may take 24 to 48 hours to fully resolve, even with medication. Respiratory symptoms, such as wheezing or coughing, can persist for a day or two, particularly if the reaction affects the airways. Severe Reactions (Anaphylaxis): Anaphylaxis is a life-threatening condition that requires immediate medical intervention, typically with the administration of epinephrine (such as an EpiPen). Once treated, the acute symptoms of anaphylaxis usually resolve within 30 minutes to a few hours. However, in some cases, a second wave of symptoms known as biphasic anaphylaxis can occur hours after the initial reaction, sometimes up to 12 hours later. For this reason, individuals who experience anaphylaxis should be monitored in a medical setting for 4 to 6 hours after the initial treatment. Delayed Reactions: Some people may experience delayed allergic reactions to shellfish, particularly involving gastrointestinal symptoms such as nausea, cramps, or diarrhea. These delayed symptoms can appear several hours after consuming shellfish and may last for up to 48 hours.
