Some medical conditions may interact with collagenase clostridium histolyticum. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

Some MEDICINES MAY INTERACT with collagenase clostridium histolyticum. Tell your health care provider if you are taking any other medicines, especially any of the following:

This may not be a complete list of all interactions that may occur. Ask your health care provider if collagenase clostridium histolyticum may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
