How to Avoid Counterfeit Weight-Loss Medications

Important: Medication instructions are product- and patient-specific. Contact the prescribing clinician before changing a dose, schedule, product or treatment plan.

What to do

Use a licensed pharmacy

Verify the pharmacy with the relevant state board and use a valid prescription from an identifiable clinician.

Inspect the package

Check product, strength, lot, expiration, seal, spelling and device appearance. Contact the pharmacy when anything differs.

Protect the cold chain

Follow product storage instructions and question warm, damaged, frozen or anonymously repackaged shipments.

When prompt medical guidance is important

  • Social-media, marketplace or messaging-app sales
  • No prescription or clinician relationship
  • “Research use only” products promoted for self-injection
  • Pressure to pay by wire, cryptocurrency, gift card or friends-and-family transfer

Call 911 for severe breathing difficulty, loss of consciousness, stroke-like symptoms or another emergency.

How W8MD can help

W8MD reviews the exact product, dose, symptoms, medical history, other medicines, nutrition, hydration, sleep, insurance and goals. The plan may involve slower escalation, another medication, nutrition support, sleep evaluation or discontinuation when benefit no longer outweighs risk.

Frequently asked questions

What if my pen looks different?

Do not use it until the dispensing pharmacy verifies the product.

Where can a problem be reported?

Contact the pharmacy, manufacturer when applicable and FDA MedWatch.

Is an overseas brand automatically counterfeit?

Not automatically, but importing or using products outside authorized U.S. channels creates legal and safety concerns.
