    Compounded GLP-1 Medicines: What FDA Approval Means

    Compounded semaglutide and tirzepatide products are not FDA-approved finished drugs. FDA does not review compounded products for safety, effectiveness, or quality before marketing, and says compounded drugs should be used only when a patient’s medical need cannot be met by an approved drug.

    Key answer

    The short version

    Compounded semaglutide and tirzepatide products are not FDA-approved finished drugs. FDA does not review compounded products for safety, effectiveness, or quality before marketing, and says compounded drugs should be used only when a patient’s medical need cannot be met by an approved drug.

    Compounded is not generic

    An FDA-approved generic must meet FDA standards for approval. A compounded preparation is different: it is prepared under specific legal and clinical circumstances and should not be represented as identical to an approved brand product.

    Source and dose are safety issues

    FDA has reported concerns about dosing errors, counterfeit or illegally marketed products, and salt forms of semaglutide that differ from the active ingredient in approved medicines. Use a prescription and a state-licensed pharmacy.

    Ask precise questions

    Ask whether the product is FDA-approved or compounded, who dispenses it, what the exact active ingredient and concentration are, what instructions apply, and why a compounded product is being considered.

    Clinical perspective

    How to think about this

    Prescription weight management is longitudinal medical care, not a consumer transaction. A sound plan weighs approved use, safety, nutrition, access, follow-up, and the patient’s own goals; it should never reduce a complex health decision to a promised outcome or a single number on a scale.

    Questions worth bringing to a visit

    • What FDA-approved option, if any, fits my clinical situation?
    • What safety monitoring and follow-up would I need?
    • How will we assess benefit, tolerability, and access over time?
