Overview
Histrelin isn't at regular pharmacies — it's at specialty pharmacies only. Here's how to check which specialty pharmacies have it in stock in 2026 without endless phone calls.
Is Histrelin in stock near you?
Medfinder checks real pharmacy inventory — start a search and we'll find Histrelin near you.
Checking whether a pharmacy has Histrelin (Supprelin LA) in stock is different from checking for a regular medication. You won't find it on GoodRx, you can't check a retail pharmacy app, and calling your local CVS or Walgreens won't help. Histrelin is a specialty drug — it lives in a completely different distribution system. Here's how to navigate it efficiently.
Why Standard Pharmacy Lookup Tools Don't Work for Histrelin
Most pharmacy stock-checking tools — GoodRx's pharmacy finder, NowMedsApp, or simply checking a pharmacy's website — are built for retail pharmacy inventory. They check what's on pharmacy shelves or in the pharmacy's dispensing system. Supprelin LA is not on any retail pharmacy shelf. It is stored and dispensed exclusively by specialty pharmacies, and shipped directly to the prescribing physician's office.
This means the "check stock" approach has to be completely different for Histrelin — you need to query specialty pharmacies, not retail ones.

Method 1: Use medfinder
medfinder is a service that calls pharmacies — including specialty pharmacies — on your behalf to check which ones have your medication in stock and can fill your prescription. You enter your medication name, dosage, and location; medfinder makes the calls; and you get your results by text. This eliminates hours of manual phone calls across a confusing specialty pharmacy landscape.
Method 2: Contact the Supprelin LA Support Center
The Supprelin LA Support Center, operated by Endo Pharmaceuticals (866-316-7263), maintains an up-to-date network of specialty pharmacies that carry the drug. When you call, they can:
Identify specialty pharmacies in your region that carry Supprelin LA
Check whether any network pharmacies are currently experiencing supply issues
Help coordinate the order directly to your prescriber's office
Method 3: Ask Your Prescribing Physician's Office
Practices that frequently prescribe Supprelin LA often maintain standing accounts with one or two specialty pharmacies. Ask your pediatric endocrinologist's office which specialty pharmacy they work with — they may already know exactly who has stock and can initiate the order on your behalf. This is often the fastest path to confirming availability.
Method 4: Call Specialty Pharmacies Directly
If you prefer to call directly, here are the major specialty pharmacies to try:
1-800-237-2767
1-800-456-5813
1-800-803-2523
1-855-427-4682
When calling, ask specifically: "Do you carry Supprelin LA (histrelin acetate 50 mg implant) and are you currently taking new orders?" Also confirm whether your insurance plan has a preferred specialty pharmacy network — using an out-of-network specialty pharmacy may result in higher costs.
What to Do Once You Confirm Stock
Once you've confirmed a specialty pharmacy has Supprelin LA in stock, the next steps are:
Confirm your prior authorization is approved (do not proceed without PA)
Have the prescription sent from your physician's office to that specialty pharmacy
The specialty pharmacy ships the implant to the doctor's office
Schedule the insertion procedure once shipping is confirmed

Frequently Asked Questions
Standard pharmacy stock-checking tools (GoodRx, pharmacy apps) do not include Histrelin because it is not a retail pharmacy drug. To check stock, you need to contact specialty pharmacies directly, call the Supprelin LA Support Center at 866-316-7263, ask your prescribing physician's office, or use a service like medfinder that calls pharmacies on your behalf.
Supprelin LA is not available at standard CVS or Walgreens retail locations. CVS Specialty and Walgreens Specialty (the specialty pharmacy divisions) may carry it. Contact CVS Specialty at 1-800-237-2767 or Walgreens Specialty at 1-800-456-5813 to check availability and eligibility.
Many insurance plans designate a preferred specialty pharmacy for drugs like Supprelin LA. Using a preferred pharmacy can reduce your out-of-pocket costs. Check the back of your insurance card or call your plan's member services line to identify your preferred specialty pharmacy network.
Once a specialty pharmacy receives and processes the order (including confirmed prior authorization), shipping typically takes 1–3 business days. The implant is shipped refrigerated to the physician's office. Allow additional time for prior authorization approval before the order can be placed — PA typically takes 3–10 business days.
