Making, measuring and storing the medicine
What can poor compounding do?
A compounded medicine is made to fill an order. The Food and Drug Administration (FDA) is the U.S. federal drug agency.
FDA says a poorly compounded medicine may contain unwanted material or an incorrect amount of active ingredient.
The part responsible for a medicine’s effect is its active ingredient. Ask who makes the proposed product and how to check them.

Why does clarity about the amount matter?
As of September 2026, FDA has reports of errors with compounded semaglutide injections that may have led to hospital care.
Bring the bottle label and any written directions to the prescriber or pharmacist. If those directions differ from what you were told, ask them to explain the difference.

Does every peptide need the same storage?
Storage rules depend on the specific product; there is no single temperature rule for every peptide medicine.
As of September 2026, FDA advises avoiding refrigerated weight injections if they arrive warm or were shipped without enough cooling.
Ask the pharmacist to explain the storage instructions for that exact product.

Responding to a problem
What if symptoms are severe?
Swelling of your tongue or face, or trouble breathing, may be signs of a severe allergic reaction. Such a reaction is an emergency.
Seek emergency care for severe signs of an allergic reaction.

How can I tell FDA about a medicine problem?
Medicine problems can be reported by patients straight to MedWatch, FDA’s product reporting program.
Keep the product name, label and details of what happened for the conversation about the problem.
