Interventions/Control_1
Sublingual immunotherapy using nut powder purchased, ground, and packaged by the investigators. The initial dose is 0.01 g administered in the hospital. The powder is measured using the hollow of an EpiPen trainer cap as a mold, placed under the tongue for 2 minutes, and then swallowed. After safety confirmation, participants continue once-daily administration at home. Dose escalation is considered at approximately 2-month outpatient visits according to the following steps: 0.01 g, 0.02 g, 0.05 g, 0.10 g, 0.15 g, and 0.20 g. For doses of 0.02 g or higher, powder measured multiple times is combined into a single dose and administered at once. The intervention period is up to 24 months.
