Hi Chirley,
You have already got much info about Desferal but I will write about how I received Desferal to make the picture more complete. I got Desferal for 4 days in connection with transfusions into my sc port. The homepump is about the size of a lemon and kept into a pouch with a belt (you can see the pouch at the info).

I tied the pump around my neck when I took a shower - otherwise there were no problem with the pump. The nurses put the pump in place and took it away after 4 days. They ordered it from the pharmacy and throw it away when it was empty. I had no adverse reactions.
Kind regards
Birgitta-A
