Xiapex treatment - improvement possible in 7 weeks1

A treatment course consists of a maximum of 4 treatment cycles. Each treatment cycle consists of 2 Xiapex injection procedures and one in-office penile modeling procedure. The second Xiapex injection procedure occurs 1 to 3 days after the first injection. The in-office penile modeling procedure is performed 1 to 3 days after the second injection of the treatment cycle (see picture above). It is necessary to identify the treatment area prior to each treatment cycle.

After the third office visit of each treatment cycle, the patient performs approximately 6 weeks of daily, at home penile modeling activities.

Up to 4 treatment cycles (for a total of 8 injection procedures and 4 modeling procedures) may be administered per plaque causing the curvature deformity. If the curvature deformity is less than 15 degrees after the first, second or third treatment cycle, or if the healthcare provider determines that further treatment is not clinically indicated, then the subsequent treatment cycles should not be administered.2
