Formula
Dose(n) = StartDose x (1 + EscalationRate)^n; Steps = log(TargetDose/StartDose) / log(1 + Rate)
Each step increases the dose by a fixed percentage (escalation rate). The number of steps is determined by how many multiplications are needed to go from the starting dose to the target dose. Total duration equals the number of steps multiplied by the interval between dose increases.
Worked Examples
Example 1: Peanut OIT Standard Protocol
Problem: A 30 kg child begins peanut OIT at 0.5 mg protein, targeting 300 mg maintenance dose, with 25% dose escalation every 14 days. How long will the build-up take?
Solution: Starting dose: 0.5 mg (0.017 mg/kg)\nEscalation: 25% increase every 2 weeks\nSteps: 0.5, 0.63, 0.78, 0.98, 1.22, 1.53, ... 300 mg\nNumber of escalation steps: approximately 28\nTotal duration: 28 x 14 = 392 days (approximately 56 weeks)\nCumulative exposure during build-up: ~4,200 mg
Result: 28 steps over approximately 56 weeks (13 months) to reach 300 mg maintenance dose
Example 2: Milk OIT Accelerated Protocol
Problem: A 25 kg child starts milk OIT at 1 mg protein with a 40% escalation rate every 7 days, targeting 2000 mg (about 60 ml of milk).
Solution: Starting dose: 1 mg (0.04 mg/kg)\nEscalation: 40% increase weekly\nSteps: 1, 1.4, 1.96, 2.74, ... 2000 mg\nNumber of steps: approximately 23\nTotal duration: 23 x 7 = 161 days (about 23 weeks)\nRisk level: Accelerated — higher reaction risk
Result: 23 steps over approximately 23 weeks (5.4 months) to reach 2000 mg — accelerated risk profile
Frequently Asked Questions
What is oral immunotherapy (OIT) and how does allergen exposure planning work?
Oral immunotherapy is a medical treatment approach for food allergies in which patients consume gradually increasing doses of the allergen under medical supervision to build tolerance over time. The process typically involves three phases: an initial dose escalation day performed in a clinical setting, a build-up phase lasting several months where doses are gradually increased at regular intervals, and a maintenance phase where the patient continues consuming the target dose daily. An allergen exposure planner helps map out the escalation schedule by calculating the number of steps, timeline, and dose progression from a very small starting dose to the target maintenance dose. This planning tool is meant for educational visualization only and all actual treatment must be supervised by a board-certified allergist experienced in food allergy immunotherapy protocols.
What are the risks and side effects associated with allergen exposure therapy?
Oral immunotherapy carries real risks including mild, moderate, and potentially severe allergic reactions during the treatment process. Common side effects include oral itching or tingling, mild abdominal discomfort, and occasional nausea, occurring in approximately 10 to 20 percent of doses. More concerning reactions such as hives, vomiting, or throat tightness occur less frequently but require medical attention. Anaphylaxis, though rare, is a life-threatening risk that can occur at any point during treatment, which is why patients must always have injectable epinephrine available. Risk factors that increase reaction likelihood include exercise within two hours of dosing, illness or infection, menstruation, high pollen season for cross-reactive allergens, and taking the dose on an empty stomach. All OIT patients require regular follow-up with their treating allergist throughout the entire treatment process.
Is Allergen Exposure Planner a substitute for medical advice on allergen immunotherapy?
Absolutely not. This allergen exposure planner is designed exclusively for educational and visualization purposes to help patients and families understand the general structure and timeline of allergen immunotherapy protocols. It should never be used to design, modify, or self-administer an allergen immunotherapy protocol without direct supervision from a board-certified allergist or immunologist. Food allergy immunotherapy involves significant medical risks including anaphylaxis, and every patient requires individualized assessment, dose determination, and ongoing monitoring by qualified medical professionals. The dosing schedules shown here are simplified mathematical models that do not account for individual patient factors such as baseline sensitivity, comorbidities, concurrent medications, or real-time allergic reactions that may require dose adjustments. Always consult your allergist before making any changes to your treatment plan.
