Know what to do when something is unclear.

For severe allergic symptoms, get emergency help

Sudden breathing trouble or a swollen tongue or face can signal anaphylaxis, a severe allergic reaction.

Call 911 if symptoms are severe, including difficulty breathing or a tongue that is swelling.

This is a reason to get urgent help, rather than trying to identify the cause from a webpage.

Do not guess through a confusing label

Compounded means made to order. Reviewing medicines is work the Food and Drug Administration (FDA) does for the U.S. government.

As of September 2026, semaglutide medicines have approval for type 2 diabetes or for weight management, depending on the product.

Reports sent to FDA describe errors involving semaglutide injections prepared through compounding; some reports involve hospital stays.

If medicine instructions are unclear, ask your prescriber or pharmacist to explain them before you follow them.

Keep your questions tied to the exact product you received.

Check storage for your particular product

There is no storage rule for all peptide medicines: some need cold storage and others do not.

Read the product’s storage information and ask the pharmacy about an unexpected delivery condition.

Ask how to handle that product, rather than using a general peptide rule.

You can report a problem

Through FDA’s free MedWatch service, patients and health professionals can report problems with medicines.

A report does not, by itself, establish that a medicine caused the problem.

Ask the person treating you about the problem as well.

A report is a record, not a personal care assessment.
