How to Help Your Patients Find Insulin Analog, Lispro Mixed in Stock: A Provider's Guide

When patients call your office saying they cannot find their Humalog Mix 75/25 or Mix 50/50, the clock is ticking. Insulin-dependent patients cannot wait days for a resolution. This guide gives your clinical and administrative staff a structured, efficient workflow for handling these calls — from the first patient contact through pharmacy verification and, if necessary, alternative therapy.

Step 1: Triage the Urgency

When a patient calls about an unavailable insulin, your staff's first task is to establish urgency. Ask:

• How many days of insulin supply do you have remaining? Fewer than 3 days = immediate clinical escalation. 3–7 days = urgent same-day response. 7+ days = standard response.
• Have you contacted any other pharmacies? If not, direct them immediately to medfinder or specific pharmacies to check first.
• Are you experiencing any symptoms of high blood sugar right now? If yes, this becomes a medical emergency conversation.

Step 2: Direct Patients to Pharmacy Search Tools

Rather than having your staff spend time calling pharmacies, direct patients to medfinder. medfinder calls pharmacies near the patient's location and reports back which ones have Insulin Analog, Lispro Mixed in stock. The patient receives the results by text — saving both your staff time and the patient's.

If the patient cannot access medfinder, have your medical assistant call 3–5 pharmacies in the patient's ZIP code to locate stock. Prioritize large retail chains (CVS, Walgreens), grocery pharmacies, and hospital outpatient pharmacies. Ask specifically: "Do you have Humalog Mix 75/25 [or 50/50], 10 mL vial [or KwikPen], in stock today?"

Step 3: Redirect the Prescription if Needed

If your staff locates a pharmacy with stock, call in, fax, or electronically send a new prescription to that location. Insulin is not a controlled substance, so there are no additional prescribing restrictions. Confirm the pharmacy can fill it before the patient makes the trip.

Consider prescribing a 90-day supply to a mail-order pharmacy if the patient has had ongoing difficulty finding local stock. Most insurance plans cover mail-order prescriptions and offer reduced copays for 90-day fills.

Step 4: Evaluate Whether an Alternative Is Appropriate

If Insulin Analog, Lispro Mixed is genuinely not available within reasonable distance, consider the following clinical alternatives:

• NovoLog Mix 70/30: Closest analog alternative. 1:1 unit conversion is a reasonable starting point with enhanced monitoring. Educate patient that timing remains the same (within 15 minutes of a meal).
• Humulin 70/30 or Novolin 70/30: Traditional human insulin as a bridge. Educate patient that injection timing shifts to 30 minutes before meals.
• Basal-bolus conversion: For appropriate patients, this shortage may be an opportunity to reassess their regimen. A basal-bolus approach with insulin glargine + insulin lispro offers greater flexibility and independent dose titration.

Patient Counseling Script for Availability Issues

Here is a brief script your staff can use when advising patients:

"Your difficulty finding this medication is real and not uncommon right now. Here are your options: First, try medfinder.com — they will check pharmacies near you for stock and text you the results. If you find a pharmacy with stock, call us and we will send the prescription there right away. If you cannot find it anywhere near you, call us back and we will discuss a temporary alternative that is safe for you. Under no circumstances should you take less insulin than prescribed or try to dilute it."

Cost Assistance Programs to Mention to Patients

If patients are at a pharmacy with stock but worried about cost, remind them of these programs:

• Lilly Insulin Value Program: $35/month for Humalog Mix with commercial insurance or cash (insulins.lilly.com)
• Lilly Cares Patient Assistance: Free insulin for qualifying uninsured, low-income patients
• Medicare: $35/month insulin cap under the Inflation Reduction Act
• GoodRx: Coupon prices as low as $81.36 at participating pharmacies

Building a Proactive Practice Protocol

Rather than responding reactively to shortage calls, consider adding a proactive step at annual diabetes visits: ask patients if they have had difficulty obtaining their insulin at any point in the past year, and ensure they are enrolled in the Lilly Insulin Value Program if applicable. Directing patients to medfinder for providers as a go-to resource for pharmacy access issues can reduce after-hours calls and reduce the risk of dangerous insulin gaps.
