Question
Can I reuse or pre-fill syringes?
Sunny, owner notes“I wish my dog lived as long as I do.”Updated
I'm an owner, not a vet. This is not veterinary advice, so check anything medical with your own vet.
Short answer
When shots are twice a day, it's tempting to save time by reusing syringes or filling them in advance. Check with your vet or pharmacist first, for your exact insulin and syringes. A syringe filled early may not stay safe to use. If drawing up each dose is hard for you, tell your vet and ask for an easier way that's still safe.
What to know at home
Shortcuts are tempting when several people share the care or your hands shake. Tell your vet what you need help with. Advice for your exact insulin matters more than what another owner does.
What to write down
- The device and prescribed product
- Why preparing treatment at the time is difficult
- Who will handle or transport supplies
What to ask next
Ask the vet whether your syringes are single use, and what other options there are. Put used needles in your sharps box, and keep insulin and syringes where kids and pets can't reach them.
