ED Meds, Caverject Impulse

The ED Meds Caverject Impulse is a prostaglandin (PGE-1) which works by relaxing certain muscles in the penis and widening blood vessels.  In turn this increases blood flow to the penis and helps to cause, and maintain an erection. When the effect of the treatment wears off, blood flow returns to normal and the erection disappears.

  •  You suffer from  conditions that may increase your risk for a prolonged, painful erection (priapism)
  •  You have penile problems such as an implant, deformity, Peyronie disease or fibrosis of the penis
