Know who answers when something is wrong.

Get a follow-up route before agreeing

Ask who answers a question after the visit and how to reach them. Ask which problems need urgent help instead of waiting for a reply through the care service’s website.

A compounded medicine is one mixed or changed by a pharmacist or doctor.

FDA, the US medicine regulator, has received reports involving compounded semaglutide, possible dose errors and hospital care.

Take unclear directions to the pharmacist or whoever prescribed your medicine and ask for an explanation. Ask them to use the product in front of you; a worksheet cannot tell you the amount to take.

Ask about this product’s handling

A peptide medicine may belong at room temperature or in a fridge; check the product’s own directions.

Ask the pharmacist to point out the storage directions for the exact medicine. Ask how to deal with a delivery that does not match them.

Poor preparation can leave a compounded medicine dirty.

Its treatment ingredient, also called the active ingredient, may be present in an incorrect amount.

Ask which pharmacy prepared it, then check that pharmacy’s record.

Watch for “for research purposes” on the label

FDA advised avoiding semaglutide, tirzepatide or retatrutide sold to people under research-use labels, as checked on September 26, 2026.

The wording included “not for human consumption”; some labels said “for research purposes”.

Unknown quality and possible harm were FDA’s concerns about those products.

A report adds information

MedWatch is FDA’s route for a patient to submit a suspected problem with a medicine.

A reported problem can be a clue; it cannot by itself establish that the medicine was responsible or measure how common the problem is.
