Record provenance
Details are drawn from this provider's public record in the CMS National Provider Identifier registry, which CMS last updated on September 17, 2009. Registry specialty indicates the care a provider is registered to deliver — it is not confirmation that this practice currently prescribes GLP‑1 medications. Call to confirm current services, availability, and pricing.
Primary care and GLP-1 treatment
Family and internal medicine providers manage weight as part of whole-person care. A primary-care-based GLP-1 program can be a good fit if you want your weight, labs, blood pressure, and other medications managed in one place — and it often simplifies insurance coverage.
Asking about GLP‑1 treatment at Marshall Zablen
Call (818) 779-1900 and ask these questions before booking:
- ✓Do you currently prescribe GLP‑1 medications (semaglutide or tirzepatide) for weight loss?
- ✓Do you work with my insurance, or is the program cash-pay — and what does a month cost all-in?
- ✓Is the medication a brand-name product, or compounded by a compounding pharmacy?
- ✓What follow-up is included for dose changes and side effects?
About compounded medications: A compounded drug is prepared by a state-licensed compounding pharmacy. Compounded drugs are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality, and they are not the same as FDA-approved generic drugs. Ask any practice which it dispenses and which pharmacy prepares it.
