Safety & pharmacy

Is compounded semaglutide or tirzepatide safe and legal?

By Zenbody Published 3 min read

The short answer

Compounding is legal in the U.S., and state and federal law regulate it, including when a pharmacy may compound. Safety is the harder part: compounded semaglutide and compounded tirzepatide aren’t FDA-approved, they can cause side effects, and a licensed clinician has to decide whether one makes sense for you before anything is prescribed.

What “compounded” means

Picture a pharmacy that makes a medicine for one specific person, working from that person’s prescription. That’s compounding. State boards of pharmacy oversee these pharmacies, and federal law sets conditions on what they may compound and when. None of that adds up to FDA approval, and you should know the difference before you start.

They aren’t generic versions of a brand-name drug, either. Different products, plain and simple.

What “safe” can honestly mean

We’re not going to tell you any medicine is safe for everyone. Be careful with anyone who does. What you can check is how the decision gets made. At Zenbody:

  • Before anything is prescribed, a clinician licensed in your state goes through your health history.
  • No prescription, no shipment.
  • Most people start low, and only the clinician changes the dose.
  • Your label names the pharmacy that filled it. Its license is public, and here’s how to look it up.

FDA’s advice for anyone considering a compounded drug is to get a prescription from a licensed prescriber and fill it at a state-licensed pharmacy.

Side effects

The common ones are nausea, vomiting, diarrhea, constipation and stomach pain, and serious side effects can happen too. You’ll get full safety information from your clinician and the pharmacy.

Severe stomach pain that won’t go away, vomiting that won’t stop, or trouble breathing? Call 911 or go to an emergency room.

Four questions to ask any provider

  1. Who prescribes, and are they licensed in my state? At Zenbody, clinicians work through Remedora Inc., PC, a medical group, and the clinician who reviews you is licensed in the state where you are.
  2. Which pharmacy fills it? Zenbody’s injections come from Rx Route in Tomball, Texas, and its tablets from Epiq Scripts in Richardson, Texas. More on both.
  3. What will I pay after month one? Zenbody posts it: $249 a month for the semaglutide injection after a $149 first month, for example.
  4. What happens if I’m not approved? At Zenbody, you’re fully refunded.

If those answers work for you, start your assessment.

Common questions

How is compounded semaglutide different from brand-name medication?

It’s a different product, and it isn’t FDA-approved. A pharmacy prepares it for an individual patient with a prescription.

Compounding is legal and regulated in the U.S., within the limits federal law sets. A licensed clinician has to prescribe it for you, and a licensed pharmacy has to fill it. Zenbody is LegitScript certified, and its partner pharmacies are state-licensed.

Who checks the pharmacy?

State boards of pharmacy license pharmacies. You can search your state board’s website for the pharmacy named on your label. NABP’s directory links to every state’s board.
