How to Check If a Pharmacy Has Lomustine In Stock (Without Calling)

Lomustine (Gleostine) is not stocked at most retail pharmacies. If you don't check availability before making a trip, you may find yourself making multiple stops — a real problem for cancer patients who are already dealing with fatigue and a packed treatment schedule. Here's how to verify pharmacy stock for lomustine before leaving home.

Why Lomustine Is Not at Every Pharmacy

Lomustine is classified as a hazardous chemotherapy drug. Pharmacies that handle it need specialized training, proper safety equipment, and certification. Additionally, because only one dose is dispensed every 6 weeks per patient, retail pharmacies see very low demand and typically don't stock it routinely. Specialty pharmacies affiliated with cancer centers are the most reliable sources.

Method 1: Use medfinder (Fastest Option)

medfinder was designed specifically for situations like this. You provide your medication name (lomustine or Gleostine), dosage, and zip code. medfinder calls pharmacies in your area on your behalf to check which ones have it in stock. Results are texted to you — no hold times, no repeated calls on your end. This is the fastest way to check multiple pharmacies at once.

Method 2: Call Specialty Pharmacies Directly

If you prefer to make calls yourself, focus on specialty pharmacy networks rather than retail chains. Call the specialty pharmacy division (not the retail counter) of:

CVS Specialty: 1-800-237-2767 (separate from retail CVS)

Accredo (Express Scripts): Available through your Express Scripts plan

Cancer center pharmacy: Call the pharmacy department at your treating institution directly

Method 3: Ask Your Oncologist's Office to Check

Your oncologist's office typically has established pharmacy relationships for specialty drugs. They may already know which pharmacies in your area reliably stock lomustine. This is especially useful if you're a new patient who hasn't yet established a relationship with a pharmacy.

Method 4: Use GoodRx or SingleCare to Find Stocking Pharmacies

GoodRx and SingleCare show pharmacies near you with pricing for lomustine. While they don't always reflect real-time inventory, pharmacies that show a price are typically ones that can order the drug — even if they don't have it on the shelf today. When you see a price listed, call that specific pharmacy to confirm they have it in stock or can order it for your prescription date.

Method 5: Transfer Your Prescription to a Known Specialty Pharmacy

Rather than checking inventory at every pharmacy near you, consider having your oncologist send the prescription directly to a known specialty pharmacy that you've confirmed stocks lomustine. This eliminates the search process for future cycles — once you establish a relationship with a pharmacy that reliably carries it, stick with them.

Tips for a Smooth Pharmacy Experience with Lomustine

Order at least 1 week in advance. Even specialty pharmacies may need to order specific capsule strengths; give them lead time.

Tell the pharmacist your exact dose and capsule strengths. A 130 mg/m² dose may require multiple capsule strengths — confirm all are available.

Keep your oncologist in the loop. If you're having significant trouble filling your prescription, tell your oncologist's office — they may be able to route it through a different channel.

Confirm insurance authorization before the refill date. Prior authorization for the next cycle should be in place before you call to check inventory.
