Just had my vet prescribe the solostar pen to be more economical with Lantus. My vet just called me and said the pharmacist didn't think it was possible to use a syringe to draw insulin from the pen - that I would need special needles to use the pen. Can anyone explain how I get to the rubber stopper on the solostar and draw out the insulin. I've been using a 10ml vial until now. I would like to find out if this is possible before I pick up the solostar tomorrow. Thank you for sharing your Lantus wisdom.
