Alternatives to Collagenase If You Can't Fill Your Prescription

When You Can't Get Collagenase, You Still Have Options

Your doctor prescribed Collagenase Santyl Ointment for wound debridement, but your pharmacy doesn't have it. Maybe they told you it's on backorder. Maybe they don't stock it at all. Whatever the reason, you're stuck — and your wound still needs care.

The good news is that while Collagenase Santyl is the only FDA-approved enzymatic debriding ointment in the US, there are other effective approaches to wound debridement that your doctor can consider. Let's walk through what Collagenase does and what alternatives might work for you.

What Is Collagenase and What Does It Do?

Collagenase Santyl Ointment is a prescription topical medication used to remove dead or damaged tissue from chronic wounds and severe burns. The "dead tissue" in a wound is called necrotic tissue or eschar, and it needs to be removed so the wound can heal properly.

The process of removing this dead tissue is called debridement. Without debridement, wounds can become stuck in the inflammatory phase of healing, increasing the risk of infection and preventing new, healthy tissue from forming.

For a complete overview, see our guide on what Collagenase is and how it's used.

How Does Collagenase Work?

Collagenase is an enzyme produced by the bacterium Clostridium histolyticum. When applied to a wound, it selectively breaks down denatured collagen — the structural protein in dead tissue — at seven specific sites along the collagen strand.

What makes Collagenase unique is its selectivity: it targets dead tissue while preserving the healthy granulation tissue underneath. The collagen fragments it creates also attract immune cells (like macrophages) that further support the healing process.

This is why your doctor specifically prescribed it — enzymatic debridement with Collagenase is gentle, selective, and can be applied at home.

Alternative #1: Medihoney (Medical-Grade Honey)

Medihoney is made from Active Leptospermum Honey (Manuka honey) and is FDA-cleared for wound management. It works through autolytic debridement — creating a moist wound environment that helps the body's own enzymes break down dead tissue.

How it works:

• Creates a moist, low-pH environment that promotes natural debridement
• Has natural antibacterial properties that help prevent infection
• Supports new tissue growth and wound closure

Pros:

• Available without a prescription in many forms (gel, paste, dressings)
• Generally less expensive than Collagenase Santyl
• Natural antibacterial properties
• Can be used on a wide range of wound types

Cons:

• Works more slowly than enzymatic debridement
• May cause a temporary stinging sensation
• Not as targeted as Collagenase — doesn't specifically break down collagen

Best for: Partial-thickness wounds, mild to moderate necrotic tissue, patients who prefer a more natural approach.

Alternative #2: Hydrogel Dressings

Hydrogel dressings (like Intrasite Gel, DuoDERM Hydroactive Gel, or Curafil) are water-based gels that promote autolytic debridement by donating moisture to dry wound beds and softening eschar.

How they work:

• Hydrate the wound bed, softening dead tissue so the body's own enzymes can break it down
• Maintain a moist healing environment
• Can be used under secondary dressings

Pros:

• Widely available at pharmacies and medical supply stores
• Easy to apply and generally well-tolerated
• Soothing and cooling — can reduce wound pain
• Available over the counter in many formulations

Cons:

• Slower debridement than Collagenase
• Not effective for thick, hard eschar without crosshatching
• Requires regular dressing changes
• Not appropriate for heavily draining wounds

Best for: Dry wounds, wounds with thin layers of necrotic tissue, maintaining a moist healing environment.

Alternative #3: Sharp or Surgical Debridement

Sharp debridement involves a healthcare provider using a scalpel, scissors, or curette to physically remove dead tissue from the wound. Surgical debridement is a more extensive version performed in an operating room.

How it works:

• Dead tissue is directly cut away from the wound bed
• Provides immediate, thorough debridement
• Can be combined with other methods for ongoing wound management

Pros:

• Fastest method of debridement — immediate results
• Most effective for thick eschar and heavily necrotic wounds
• Can be performed in a wound care clinic or at bedside

Cons:

• Must be performed by a trained healthcare provider
• Can be painful (local anesthesia may be needed)
• Risk of bleeding and damage to healthy tissue
• Cannot be done at home

Best for: Thick eschar, wounds with significant necrotic tissue, urgent situations where rapid debridement is needed.

Alternative #4: Wet-to-Dry Dressings (Mechanical Debridement)

Wet-to-dry dressings involve applying a moist gauze to the wound and allowing it to dry. When the dressing is removed, dead tissue comes off with it.

How it works:

• Moist gauze is applied to the wound and left to dry
• As the gauze dries, it adheres to the wound surface
• When removed, dead tissue is pulled away with the gauze

Pros:

• Simple and inexpensive — uses standard gauze
• Can be effective for moderate amounts of necrotic tissue
• Widely available

Cons:

• Non-selective — can remove healthy tissue along with dead tissue
• Painful during dressing changes
• Considered less modern compared to enzymatic or autolytic methods
• Requires frequent dressing changes

Best for: Situations where other debridement methods aren't available, short-term use while sourcing Collagenase.

Which Alternative Is Right for You?

The best alternative depends on your wound type, severity, and your provider's clinical judgment. Here's a quick comparison:

• Mildly necrotic wounds: Medihoney or hydrogel dressings
• Thick eschar: Sharp debridement followed by enzymatic or autolytic maintenance
• Home care: Medihoney or hydrogel (easiest for self-application)
• Fastest results: Sharp debridement (requires provider visit)

Important: Don't switch wound care methods without talking to your doctor first. Your provider knows your wound best and can recommend the most appropriate alternative based on your specific situation.

Don't Give Up on Finding Collagenase

While alternatives exist, Collagenase Santyl remains the gold standard for enzymatic wound debridement. If you're having trouble finding it, try these steps before switching:

• Use Medfinder to check pharmacy stock in real time
• Try independent and specialty pharmacies
• Ask about savings programs if cost is a barrier
• Check the latest shortage updates

Final Thoughts

Not being able to fill your Collagenase prescription is stressful, but it doesn't mean your wound care has to stop. Medihoney, hydrogel dressings, and sharp debridement are all legitimate alternatives that can keep your wound healing on track while you work on sourcing Santyl.

Talk to your doctor, explore your options, and use tools like Medfinder to stay on top of availability. Your wound deserves proper care — and there's always a path forward.
