Adverse drug reactions (ADRs) and adverse drug events (AEs) were systematically collected and analyzed.ResultsThe mean patient age was 49.65 years, with 96.47% being over 18 years of age. A single dose exceeding 4 mL was administered in 98.34% of the cases, with a median treatment duration of 7 days. Concomitant medication use was high (injectable, 98.43%; non-injectable, 75.43%). One case of vertigo was reported as an ADR in a patient aged >60 years who had melanoma.ConclusionThe ADR rate was 0.03%, confirming the favorable safety profile of placental polypeptide injection. These findings support its safe clinical use and can inform future regulatory and policy decisions.
