Him! we have we have come down to Universal Studios in Orlando, Flirida as a surprise for my son's birthday. Unfortunately I have forgotten cartridges. I dialyzed yesterday morning and my nurse tells me that she cannot get cartridges to me until Sunday, which is too long. None of the local pharmacies hold kaelexate and I am extremely worried that this anyone who lives in this area, that would be able to key me have a couple of theirs. I use the 170c? The one with the access pressure pod for short daily but at a push, a 171B would do (better than missing dialysis. If you do, can you give me a call on 678 227 8942, or respond to me with via here with contact details. Alternatively my e-mail is amanda100wilson@hotmail.com.., thank you so much.
