I had a RALP with 50% nerve sparing, an emergency bowel resection after complications and are now just over 4 months out. I am using 5mg of tadalifil per day and other than twinges here and there are not getting any where near a normal erection. I am also using daily/ every other day a Soma erect II VED device.
I initially tried alprostadil but had very painful penile pain and about a 3 hour erection on the standard first clinic administered dose so after feeding this back , then approached my CNS for invicorp. I had already been trained on alprostadil injections so I was prescribed a first dose of invicorp without it being administered in clinic so self administered at home .
The standard first dose is 25mg (about 30 units on syringe )) from a 35mg ampoule of invicorp and due to the penile pain and long erection previously on alprostadil i only injected 10 units ( about 7-8mg )
It was firm enough for intercourse and was pain free which initially was great.
I then had a priapism (4 hour erection) though even with this low dose and had to go to A&E for urgent treatment .
After being admitted by the urology team overnight for observation the consultant in the morning then removed invicorp ( obviously) from my prescription list.
Has anyone else had this severe reaction and if so is there an alternative ?
Reading the instructions provided in the invicorp pack this reaction seems to be very rare so I am obviously very disappointed.
thanks Ant
