When considering "how long Alfaxan lasts," it's important to differentiate between two key aspects: the duration of its effect in an animal and the usable shelf-life of the opened product. For the ALFAXAN MULTIDOSE product, once first punctured, it should be used within 56 days.
Understanding Alfaxan's Duration
Alfaxan, a commonly used anesthetic in veterinary medicine, has durations related to both its pharmacological action and its product stability once opened.
Duration of Product Usability (Opened Vial)
The stability and integrity of ALFAXAN MULTIDOSE after the vial is first punctured are crucial for safe and effective use. Due to the presence of preservatives, ALFAXAN MULTIDOSE has a specific timeframe for use once opened.
- Usability Period: After the first puncture, ALFAXAN MULTIDOSE should be used within 56 days.
- Discard Policy: Any unused ALFAXAN MULTIDOSE remaining after this 56-day period must be discarded to ensure safety and efficacy.
- Mixing Restrictions: It is important to note that ALFAXAN MULTIDOSE should not be mixed with other therapeutic agents prior to administration.
This information is vital for veterinary clinics and professionals to manage their inventory and ensure proper drug handling, preventing contamination and maintaining drug potency.
Here's a quick reference for the opened product's stability:
| Product Status | Duration of Use | Action After Period | Key Information |
|---|---|---|---|
| First Punctured | 56 Days | Discard Unused | Contains preservatives; do not mix with other agents prior to administration. |
Duration of Pharmacological Effect (In Patient)
The duration of Alfaxan's pharmacological effect, meaning how long its anesthetic or sedative properties last in an animal after administration, varies depending on factors such as the dose given, the animal's species, individual metabolism, and other concurrent medications. This aspect of the drug's duration is not covered by the provided product usability information. Veterinary professionals determine appropriate dosing and monitor patient response to manage the desired duration of anesthesia.
