1. What Invicorp is and what it is used for
The active components in Invicorp (aviptadil and
phentolamine mesilate) affect the flow of blood in
and out of the penis. In broad outline,
phentolamine mesilate increases the flow of blood
into the penis, while aviptadil reduces the flow of
blood from the penis.
If you suffer from an erectile dysfunction, you can
use Invicorp to help you to obtain an erection
more easily.
2. What you need to know before you use

the blood), multiple myeloma (bone cancer) or
sickle cell anaemia or trait (a blood disease),

− if you have a penis which is scarred or not
straight which may sometimes be referred to as
Peyronie’s disease or if you have abnormal

(cavernosal fibrosis)
− if you have an implant in your penis.

Talk to your doctor, pharmacist or nurse before
using Invicorp if:
