This product is used to help the healing of burns and skin ulcers. Collagenase is an enzyme. It works by helping to break up and remove dead skin and tissue. This effect may also help antibiotics to work better and speed up your body's natural healing process.
This medication is for use on the skin only. It is usually applied once daily or as directed by your doctor. If the dressing becomes soiled, collagenase may be applied more frequently.
To apply, wash hands first. Clean the area as directed by your doctor. Cleaning solutions such as hydrogen peroxide, normal saline, or Dakin's solution may be used. If your doctor has directed you to use an antibiotic powder, apply it first before applying this medication. Use a wooden spatula or a gauze pad to carefully apply the collagenase ointment directly to the affected area. Bandage securely. If you are unclear about how to clean the affected area or apply this medication, consult your doctor.
Avoid applying near the eyes. Be careful to apply the ointment only within the affected area. Wash hands thoroughly after applying the ointment.
Pain or a burning feeling at the affected area may occur. Temporary redness/irritation may also occur in the skin around the affected area. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. To avoid redness/irritation in the surrounding skin, be careful to apply the ointment only within the affected area.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Treatment of burns and skin ulcers by breaking up and removing dead skin and tissue may rarely increase the risk for serious infection (sepsis).

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
