How to Find Entrectinib (Rozlytrek) in Stock Near You: Tools and Tips

Filling a prescription for Entrectinib (Rozlytrek) requires more steps than picking up a regular medication. As a specialty oncology drug dispensed exclusively through specialty pharmacies, finding it "in stock" means navigating a network of specialized dispensers, insurance requirements, and financial assistance programs. This guide walks you through exactly how to get your prescription filled — fast.

Why Finding Entrectinib Is Different from Other Medications

Entrectinib isn't stocked at CVS, Walgreens, or your local grocery store pharmacy. It is only available through specialty pharmacies — either free-standing specialty dispensers or specialty arms of major retail chains. Your insurer also plays a major role: most plans require prior authorization before they'll cover Rozlytrek, and they may only work with one or two preferred specialty pharmacy providers.

Step 1: Start with Genentech Access Solutions

The single fastest way to get your entrectinib prescription filled is to call Genentech Access Solutions at 877-436-3683 (Monday–Friday, 6am–5pm PT). This is Genentech's dedicated hub for Rozlytrek access. They can:

Conduct a benefits investigation to determine your coverage and copay

Identify which specialty pharmacy is preferred by your insurance plan

Initiate or support the prior authorization process

Connect you to copay assistance programs or the Genentech Patient Foundation

Step 2: Ask Your Oncologist's Office for Help

Large oncology practices and cancer centers typically employ pharmacy liaisons or patient care coordinators who specialize in navigating specialty drug access. Before you spend hours on hold with your insurer, ask your oncologist's office if they have someone who can manage the specialty pharmacy routing and prior authorization paperwork on your behalf. Many offices do this routinely for targeted therapies like Rozlytrek.

Step 3: Use medfinder to Find Which Pharmacies Can Fill Your Prescription

If you'd rather not spend hours calling pharmacies yourself, medfinder does the legwork for you. You provide your medication, dosage, and location, and medfinder's team contacts pharmacies in your area to find out which ones can fill your prescription. Results are sent directly to your phone via text.

Step 4: Know Your Specialty Pharmacy Options

Major specialty pharmacy chains that dispense Rozlytrek include:

CVS Specialty — one of the most widely contracted specialty pharmacies in the country

Walgreens Specialty / AllianceRx Walgreens Prime — covers many commercial and Medicare plans

Accredo (Evernorth Health) — preferred by some Cigna and Aetna plans

Optum Specialty Pharmacy — common for UnitedHealthcare members

Hospital/health system specialty pharmacies — many cancer centers have on-site specialty pharmacies that are most familiar with oncology drugs like entrectinib

What If My Insurer's Preferred Specialty Pharmacy Is Out of Network for Me?

This is a common problem. If your insurer's preferred specialty pharmacy can't serve your area, ask your oncologist's office to request a specialty pharmacy exception. Genentech Access Solutions can also help navigate network conflicts. In urgent cases, your prescriber may be able to provide a short bridge supply from a clinical trial site or hospital pharmacy while paperwork is completed.

Tips to Avoid Running Out of Entrectinib

Because Rozlytrek is taken daily and cancer patients cannot safely skip doses, planning ahead is critical:

Request refills 7–10 days before you run out to account for specialty pharmacy processing time

Keep your prior authorization renewal date on your calendar — most insurers authorize for 12 months and need renewal paperwork before it lapses

Confirm your insurance coverage hasn't changed at the start of each calendar year — plan changes can affect specialty pharmacy routing

Keep Genentech Access Solutions' number saved in your phone for quick access when issues arise
