Now, as to the prescription - here is how I decrypt your post:
label says
PAP/PHEN/PGE1
30/0.5MG/25MCG/ML
needle is 3/10 ml/cc 5/16 31G
use according to the instructions, did not have doctors help.
Wow. My surgeon forbade me to open the bag. I had to bring it to him for my first "experiment".
My Rx is Pap 30, Phen 0.5,PGE 10Mcg/ml
The needle is not very relevant, except that the doc is apparently very pain-adverse, as 31g is really thin (bigger number, smaller needle). Some would say too delicate. My needle size is 27g on the syringe (to fill from the vial) then change to a 30g (thinner) for the injection. Too complicated for me, but I comply.
What I question is the PGE130 - is it PGE1 30, or PGE130? Mine is PGE 10. If if is PGE 130 as opposed to PGE1 / 30, it is a whole different Rx.
Regardless of the difference, the uro, or at least an assistant, should take you through the "first time".
