Insurance companies sometimes require you to try cheaper or older medicines before they'll pay for a newer, pricier drug like Wegovy. That requirement is called "step therapy" or "fail-first." The person who posted the question was asking what medicines tend to show up on prior-authorization forms as those first steps — basically, which drugs insurers commonly want people to try before approving Wegovy. Wegovy is the brand name for semaglutide at a higher dose used specifically for weight management. Semaglutide is a man-made version of a natural hormone from the gut that helps control appetite and slows how quickly food leaves the stomach. It’s related to Ozempic (used for diabetes) and other similar medications that target the same hormone pathway. These drugs are injections and have become well known because they can produce significant weight loss for many people. The original post is a request for practical experience, not a scientific study. It reflects that insurers vary a lot. Commonly, plans might ask you to try lifestyle programs first (diet and exercise), or older, cheaper weight-loss medications such as phentermine, or even metformin (a diabetes drug sometimes used for weight-related issues). Some plans accept documented attempts at behavioral counseling or supervised diet plans instead of another drug. Others will accept a history of trying a related drug like Ozempic or lower-dose semaglutide. There’s no single list that applies everywhere — what’s required depends on the insurer, the specific insurance plan, and sometimes the state’s rules. Why this matters: step therapy can delay access to a medicine that a doctor thinks is best. For someone who has struggled with weight and hasn’t responded to other approaches, being forced to try older drugs or programs that didn’t work for them can be frustrating and time-consuming. On the other hand, insurers say this policy helps control costs and ensure safer, well-established treatments are tried first. If you’re considering Wegovy, it’s useful to know your plan’s prior-authorization rules and to have your doctor document past treatments that failed, so you can argue that step therapy should be waived. Important caveats: the original post is a forum question asking for examples, not an authoritative source. Requirements vary widely by insurer and by state law. Some insurers have explicit lists; others handle it case-by-case. Step therapy can be appealed, and many plans allow exceptions for medical necessity, but that process can take time. Also beware side effects of any weight-loss drug: semaglutide can cause nausea, digestive upset, and in rare cases more serious problems. Always discuss options with your clinician and check your specific plan’s prior-authorization rules rather than relying on anecdotal lists. Bottom line: insurers often require trying cheaper or older treatments before approving Wegovy, but which ones depend on the plan — check your insurer and have your doctor document past attempts to make getting an exception easier.
