What is collagenase clostridium histolyticum?

Collagenase clostridium histolyticum is also used to treat a related condition called Peyronie's disease in adult men. This condition causes scar tissue or "plaque" to develop under the skin of the penis, resulting in an abnormal curving of the penis during erection.

Collagenase clostridium histolyticum for Peyronie's disease is available only under a special program. You must be registered in the program and understand the risks and benefits of collagenase clostridium histolyticum.
