Build Tolerance to Seafood with Physician-Supervised Oral Immunotherapy
AllergyWorx provides physician-supervised allergy care through oral immunotherapy (OIT) , a treatment approach that gradually introduces small, controlled amounts of seafood protein to help build tolerance over time.
Our personalized immunotherapy protocol helps train your immune system to tolerate seafood exposure, reducing the risk of severe reactions and providing greater peace of mind in daily life.
Treatment is conducted under strict medical supervision with careful monitoring, making it a safe option for eligible patients seeking long-term protection against accidental seafood exposure.

How It Works
Getting started with AllergyWorx oral immunotherapy follows a careful, medically supervised approach.
Medical Evaluation
Undergo comprehensive testing and evaluation to confirm seafood allergy and determine if oral immunotherapy is appropriate for you.
Initial Dose Escalation
Begin treatment in a controlled medical setting where small amounts of seafood protein are administered under direct physician supervision.
Gradual Build-Up Phase
Continue treatment at home with regular check-ins, slowly increasing doses over months to years while under ongoing medical monitoring and support.
Understanding Seafood Allergies
Seafood allergies encompass reactions to both fish (such as salmon, tuna, cod, halibut) and shellfish (crustaceans and mollusks). While these are often grouped together, fish allergies and shellfish allergies are distinct conditions caused by different proteins, and individuals may be allergic to one category without being allergic to the other.
Seafood allergies can develop at any age and are among the most common food allergies in adults. Unlike many childhood food allergies, seafood allergies rarely resolve on their own and typically persist throughout life. Reactions can range from mild symptoms like hives or stomach discomfort to severe, life-threatening anaphylaxis.
Cross-contamination is a significant concern with seafood allergies, as seafood proteins can transfer to cooking surfaces, utensils, and other foods during preparation. Even exposure to cooking vapors or aerosolized seafood proteins can trigger reactions in highly sensitive individuals.
Traditional management has focused on strict avoidance and carrying emergency epinephrine. Oral immunotherapy represents an emerging approach that aims to reduce reaction severity and increase the threshold amount needed to trigger symptoms providing an added layer of protection against accidental exposure.
Common Triggers
Fish
Salmon, tuna, cod, halibut, tilapia, bass, and other finned fish
Crustaceans
Shrimp, crab, lobster, crayfish, prawns
Mollusks
Clams, mussels, oysters, scallops, squid, octopus
Asian Cuisines
Dishes using fish sauce, shrimp paste, or seafood stock
Cross-Contaminated Foods
Foods prepared in shared fryers or on shared surfaces
Cooking Vapors
Airborne proteins released when seafood is cooked
Typical Symptoms
- Hives, redness, or itching of the skin
- Swelling of lips, face, tongue, or throat
- Tingling or itching in the mouth
- Nausea, vomiting, or abdominal cramping
- Diarrhea
- Shortness of breath or wheezing
- Rapid pulse or drop in blood pressure
- Dizziness or loss of consciousness
- Anaphylaxis (severe, life-threatening allergic reaction)
When untreated or unmanaged, seafood allergies can severely limit dining choices, create anxiety around restaurants and social events, restrict travel options, and pose serious safety risks during accidental exposure.
AllergyWorx helps eligible patients build tolerance through carefully supervised oral immunotherapy.
Treatment Options for Seafood Allergies
AllergyWorx offers physician-supervised oral immunotherapy (OIT) that helps build tolerance to seafood protein through gradual desensitization.
Oral Immunotherapy (OIT):
Carefully controlled introduction of seafood protein under medical supervision
Gradual Dose Escalation:
Slow, incremental increases over months to years
Desensitization Goal:
Reduce reaction severity and increase tolerance threshold
Emergency Preparedness:
Epinephrine always available during treatment
Ongoing Medical Monitoring:
Regular check-ins and adjustments based on response
Treatment protocols are based on emerging clinical research and are administered under physician supervision.
Important Note: Oral immunotherapy for seafood allergy is not a cure and does not work for everyone. Patients must continue regular seafood consumption to maintain desensitization, and epinephrine should always be available for emergencies. Your AllergyWorx physician will determine if you are a suitable candidate.
Lifestyle & Prevention Tips for Seafood Allergies
Read all food labels carefully
Seafood ingredients can appear in unexpected products and sauces.
Carry epinephrine auto-injectors
At all times and ensure they are not expired.
Wear medical alert identification
Bracelets or necklaces that clearly state your seafood allergy.
Communicate your allergy clearly
To restaurant staff and ask about cross-contamination risks.
Avoid seafood restaurants
Even if ordering non-seafood items, cross-contamination is extremely common.
Be cautious with Asian cuisines
Fish sauce, oyster sauce, shrimp paste, and seafood stock are common ingredients.
Check supplement ingredients
Omega-3 fish oil and glucosamine from shellfish are common in supplements.
Avoid cooking vapors
Airborne seafood proteins released during cooking can trigger reactions.
Request separate cooking equipment
Ensure no shared fryers, grills, or utensils when dining out.
Create an allergy action plan
With your physician and share it with family, friends, and caregivers.
Pro Tip
Even if undergoing oral immunotherapy, continue practicing strict avoidance of accidental exposures outside of your prescribed treatment protocol. OIT increases your threshold but does not eliminate risk entirely.
Success Stories
*Individual results may vary. Always consult your physician before starting any treatment.
Frequently Asked Questions
Is oral immunotherapy for seafood allergy a cure?
No. Oral immunotherapy is not a cure. It helps build tolerance by increasing the amount of seafood protein needed to trigger a reaction, reducing severity of accidental exposures. Patients must continue regular seafood consumption to maintain desensitization.
How long does seafood OIT treatment take?
Treatment typically takes 6 months to 2+ years, depending on the protocol and individual response. Initial dose escalation occurs in a medical setting, followed by gradual at-home increases under physician supervision.
Can I be allergic to fish but not shellfish, or vice versa?
Yes. Fish allergies and shellfish allergies are distinct conditions caused by different proteins. You can be allergic to one category without being allergic to the other. Your physician will conduct comprehensive testing to determine your specific sensitivities.
Are fish oil supplements safe if I have a seafood allergy?
Not necessarily. Fish oil supplements contain fish proteins that can trigger allergic reactions. Highly refined fish oils may be safer, but you should always consult your physician before taking any fish-derived supplements if you have a seafood allergy.
