What a report tells you
The Food and Drug Administration (FDA), the federal drug agency, says a report alone does not prove a medicine caused the problem. a
The details in a report may not have been medically confirmed. a
The FDA's collection of problem reports cannot show how often a problem happens among people taking a medicine. a
That collection is called the FDA Adverse Event Monitoring System, formerly FAERS. Here, 'adverse event' means an unwanted health problem reported while someone was taking a medicine. a
What official medicine information tells you
Official medicine information sets out approved uses and cautions. It is often called the drug label.
For semaglutide (Wegovy), it describes common stomach problems and warns about a rare cancer named 'medullary thyroid cancer'. b
That warning is called a boxed warning, the FDA's strongest kind of medicine warning. b

What a trial tells you
A trial is a study of a treatment. It may compare people getting the treatment with another group.
The STEP 1 semaglutide trial compared the medicine with a dummy shot containing no active medicine; both groups had help with food and activity. c
Ask who took part, what was measured and whether the result is an average. The answers help you judge whether the study is relevant to your own health question.
Why the date matters
As of September 2026, semaglutide injections were off the FDA's national shortage list. d
Check when the shortage information was written; it can change, and an old article may not describe the supply now. d
Dates matter for prices and coverage too. When comparing claims, look for the time and the exact product they describe.
