"Medical glue" typically refers to medical adhesives used for skin wound closure (such as alpha-cyanoacrylate-based glues). Their shelf life is as follows:
In an Unopened State: The validity period for most medical adhesives is 2 years. For instance, "Compath Medical Adhesive" explicitly states a validity period of 2 years.
Certain Products: Some products (e.g., those with specific regulatory filings or packaging) may list a validity period of 3 months; however, this claim is inconsistent with mainstream products and industry standards, and it lacks broad support.
Given that the latest and most authoritative sources-such as products registered with the National Medical Products Administration (NMPA) and the consensus among physicians at top-tier (Grade 3A) hospitals-universally adopt 2 years as the standard, this 2-year** timeframe should be considered the definitive standard.
Storage Conditions: The product must be kept sealed, protected from light, and stored in an environment with a temperature range of **0–30°C** and a relative humidity of ≤80%; failure to observe these conditions may result in premature expiration.
