CM,
I would imagine your surgeons office would be the ones to write the prescription for your catheter, then the pharmacy fills the prescription. The jelly for lubrication has to be a water soluable one, and I recently had difficulty finding one when I was in my local Walgreen's Drug. There was only one product that was water soluable, and it was a KY-Jelly product. Just make sure your read the label carefully because KY makes many different types of lubricant, and you don't want to get the wrong kind. Additionally I want to mention that this lubricant is mixed in with all of those other sensual type lubricants, and my one product as I mentioned was difficult to find. Plus there was only one selection of that particular type of KY-Jelly, I almost missed it entirely as it was pushed back behind one of the other types. You can imagine there are many fewer people needing it for the reason we have, than there are people who want the other type lubricant.
Good Luck,
Lou
