Can I safely reuse an opened Eprex injection for my pet with CKD?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Male | unneutered | 4 years and 5 months old | 6 lbs

My vet has recommended me to give eprex 2000 iu injection 0.1 ml to him every 4th day . he is severally anemic because of CKD . His creatinine has become very high now . So as this injection is very expensive in my country and it's 0.5 ml in a injection so can I use the opened injection after 4 days as it's 0.5 ml and I need to use 0.1 ml at one time ...? So these injection ate usesless once opened or can I use it or store to use it later ??

This is from the manufacturer's website with regards to storing Eprex: Store at 2°C to 8°C. Do not freeze or shake. This temperature range should be closely maintained until administration to the patient. Store in original package in order to protect from light. When the product is about to be used, it may be removed from the refrigerator and stored at room temperature (below 25°C) for a maximum single period of seven days. So, if you keep it refrigerated at 2-8C even after opened, it should be OK to use. You could always call the manufacturer (phone number should be on the packaging) to get better council.
