Which statement best describes the monitoring requirement for subcutaneous immunotherapy (SCIT)?

• A. It requires supervised administration with dose escalation due to risk of systemic reactions.
• B. It can be self-administered at home.
• C. It is only used for acute allergy symptoms.
• D. No precautions are needed after injection.

Answer: (A)

The key idea is that subcutaneous immunotherapy must be given in a setting where the clinician can supervise and respond to reactions, because there is a real risk of systemic reactions, including severe anaphylaxis. During the build-up phase, the allergen dose is gradually increased to reach a maintenance dose, and this dose escalation is done under careful monitoring to catch any adverse effects early. After each injection, patients are observed for a period (commonly around 20–30 minutes) to manage any reactions promptly, with emergency medications and equipment available if needed. Because of this risk and the need for careful dose adjustments, SCIT cannot be self-administered at home, and it is not used for treating acute symptoms or without precautions after injections. This is why supervised administration with dose escalation best describes the monitoring requirement.
