How to Check If a Pharmacy Has Tesamorelin in Stock (Without Calling)

If you take tesamorelin (Egrifta SV or Egrifta WR) for HIV-associated lipodystrophy, you already know that filling your prescription isn't simple. Tesamorelin is only dispensed through specialty pharmacies — and not all of them stock it. During supply transitions (like the current shift from Egrifta SV to Egrifta WR), availability can vary significantly between specialty pharmacies in the same city. Manually calling each one is tedious and time-consuming. Here's how to do it smarter.

Why Checking Tesamorelin Stock Is Complicated

Unlike common medications that sit on a retail pharmacy shelf, tesamorelin is:

Only available at specialty pharmacies (not CVS, Walgreens, or Walmart standard locations)

Stocked in limited quantities due to its specialty biologic status and high cost

Undergoing a formulation transition — Egrifta SV is being phased out as Egrifta WR becomes the primary product, and not every specialty pharmacy has added the new formulation to its inventory yet

Tied to specific insurance networks — your plan may require a specific in-network specialty pharmacy

The Fastest Way: Use medfinder

medfinder is a service built specifically for patients who struggle to find specialty and hard-to-locate medications. Here's how it works:

You provide your medication (tesamorelin / Egrifta WR or Egrifta SV), dosage, and location.

medfinder calls specialty pharmacies near you to check which ones have your medication in stock and can fill your prescription.

Results are texted directly to you — no hold music, no repeated explanations, no wasted time.

This is especially valuable during supply transitions or when your usual specialty pharmacy is temporarily out of stock. medfinder covers all medications including specialty biologics like tesamorelin.

The Traditional Method: Calling Specialty Pharmacies Yourself

If you prefer to call yourself, here's how to be efficient about it. The main specialty pharmacy networks to check are:

CVS Specialty: 1-800-237-2767

Accredo (Express Scripts): 1-800-803-2523

AllianceRx Walgreens: 1-800-759-3203

THERA Patient Support: 1-833-23-THERA (1-833-238-4372) — can direct you to in-network specialty pharmacies that carry tesamorelin

When calling, be specific: ask for "Egrifta WR" (the newer formulation) or "Egrifta SV" (the older formulation) by name, and confirm whether they are currently dispensing it and whether they accept your insurance plan.

What to Do If No Pharmacy Has It in Stock

If you genuinely cannot find tesamorelin in stock anywhere nearby, take these steps:

Contact THERA Patient Support immediately — they may be able to coordinate supply through another specialty pharmacy in their network.

Ask your doctor about bridge options or whether your prescription can be transferred to a mail-order specialty pharmacy.

Ask about switching from Egrifta SV to Egrifta WR (or vice versa) if one is available and the other is not — note that a new prescription is required.
