We get the Rocephin and all the supplies from a company called Community Surgical in Toms River, NJ, for about $600.00 a month. We mix the powdered rocephin with a vial of sterile water and inject it directly into my son's PICC line. It is not at all difficult. The only drawback is that they do not have home care nurses. We have to go to Dan's PCP for dressing changes and blood draws.
When I was researching prices for all of this, the cheapest I found was thru Sam's Club for about $400. a month, but then you would have to find places to get the supplies. For me it was worth the difference in price to be able to get everything from one place. Good Luck
