A few possibilities - if the zyvox is a powder and just needs to be reconstituted in saline in the eclipse, you can do that yourself. It's not very hard and you can offer to do that. Another possibility is injecting it with a syringe though you might still have stability issues, not sure. When I use colistin I think they don't like it sitting for too long so either we mix it ourselves or they send us a few days' supply at a time.
