How to Help Your Patients Find Santyl In Stock: A Provider's Guide

You've assessed the wound, confirmed that enzymatic debridement with Santyl (collagenase ointment) is the appropriate treatment, and written the prescription. But what happens next? For many patients — especially those in areas without specialty pharmacy access or those with complex insurance situations — filling that prescription can be harder than expected. This guide is for wound care specialists, podiatrists, dermatologists, surgeons, and any provider who prescribes Santyl regularly and wants practical strategies for helping patients get what they need.

Why Patients Struggle to Fill Santyl Prescriptions

Understanding the barriers your patients face helps you intervene proactively. The main obstacles are:

Pharmacy availability: Santyl is a specialty wound care product. Standard retail pharmacies often don't carry it or maintain only minimal stock. Patients are frequently told it's "not in stock" or "needs to be ordered."

Prior authorization delays: Most payers require prior authorization for Santyl. If the PA isn't initiated at the point of prescribing, patients can face delays of days to weeks before coverage is approved.

Cost barriers: At retail prices of $333–$450+ for a 30-gram tube, Santyl is expensive. Even insured patients can face significant copays, especially on high-deductible plans. Without savings program information, some patients simply don't fill the prescription.

No generic alternative: Santyl is the only FDA-approved enzymatic debriding ointment in the U.S. When supply is tight at a particular pharmacy, patients can't just get a generic — they must locate the brand-name product.

Step 1: Send Prescriptions to the Right Pharmacy

The single most impactful step you can take is sending the prescription to a pharmacy most likely to have Santyl in stock. Consider:

Your affiliated or on-site pharmacy, if your wound care center or hospital has one. These are typically the most reliable source.

A specialty pharmacy that regularly carries wound care products. Develop a referral relationship with 1–2 local specialty pharmacies and make them your default.

Your insurance plan's specialty pharmacy, which may also be able to mail Santyl directly to the patient's home.

Step 2: Initiate Prior Authorization at the Point of Prescribing

Don't wait for the pharmacy to request a PA. Proactively initiate the prior authorization when you write the prescription. Document:

Diagnosis with appropriate ICD-10 code (pressure ulcer, diabetic foot ulcer, venous ulcer, severe burn)

Wound characteristics: size, depth, extent of necrotic tissue, chronicity

Prior treatments tried if step therapy is required (some payers require failure of mechanical or sharp debridement first)

Your specialist credentials if the payer requires prescribing by or in consultation with a wound care specialist

Most plans approve Santyl PA for 3-month periods. Using the Santyl dosing calculator at santyl.com/hcp/dosing when requesting larger quantities can support your PA documentation.

Step 3: Tell Patients About medfinder

If you don't have a go-to specialty pharmacy, or if patients are having trouble in your area, medfinder for Providers is a service designed to help. medfinder calls pharmacies near your patient to find which ones have Santyl in stock — eliminating the time-consuming phone calls that patients (and your staff) would otherwise make. Results are texted to the patient so they know exactly where to go.

Step 4: Arm Patients With Savings Information

Cost is one of the top predictors of prescription non-adherence. A 60-second conversation about savings programs at the point of prescribing can prevent an unfilled prescription — and a wound from getting worse:

Santyl Copay Assistance Card: For commercially insured patients. Out-of-pocket cost reduced to as little as $20–$50 per fill, with Smith & Nephew covering up to $250 per fill and up to $1,000 per year (6 fills). Available at santyl.com/card. Not valid for Medicare, Medicaid, or TRICARE.

Smith & Nephew Patient Assistance Program (PAP): Provides Santyl at no cost to eligible low-income, uninsured, or underinsured patients. Apply through santyl.com or by calling 1-800-876-1261.

GoodRx and SingleCare coupons: Can reduce the retail price significantly — GoodRx lists Santyl at approximately $346 for a 30g tube. Usable at participating pharmacies without insurance.

Step 5: Prescribe Both Tube Sizes When Clinically Appropriate

When stock is tight, a pharmacy may have the 30-gram tube but not the 90-gram, or vice versa. If clinically appropriate, consider writing prescriptions that allow substitution between tube sizes, or contact the pharmacy in advance to confirm availability before sending the prescription.

Key Clinical Reminders When Prescribing Santyl

Santyl works in the pH range of 6–8. Avoid acidic cleansers and heavy metal antiseptics (silver sulfadiazine, Betadine) on the wound.

Normal saline and Dakin's solution are compatible cleansing agents.

Apply once daily; more frequently if dressing becomes soiled (e.g., incontinence).

Discontinue once debridement is complete and granulation tissue is established.
