Recent GLP-1 updates and timeline

This page groups the major public developments by date instead of by topic. It highlights the recent label changes, regulator actions, court developments, and research updates that materially changed the current GLP-1 landscape.

At A Glance

The timeline is built from current labels, court orders, regulator statements, and selected research or trial references.
January and February 2026 materially changed how the mental-health and non-approved-product topics should be framed.
December 2025 marked the creation of the separate federal NAION vision-loss MDL.
The current best read of the landscape still centers on GI injury, NAION, and the records that anchor those events.

February 6, 2026: FDA moves against non-FDA-approved GLP-1 drugs

On February 6, 2026, FDA announced it intends to take action against non-FDA-approved GLP-1 drugs. The agency's public position matters because it sharpens the line between approved brand-label discussions and injuries involving compounded, counterfeit, or otherwise non-approved products.

That action also sharpens the line between approved brand-label discussions and injuries involving compounded, counterfeit, or otherwise non-approved products.

January 13, 2026: FDA requests removal of suicidality warning language

On January 13, 2026, FDA requested removal of suicidal-behavior and ideation warning language from the obesity GLP-1 labels that still carried it, after finding no increased risk.

That change matters because older articles and screenshots may still repeat warning language that is no longer current.

December 15, 2025: the NAION MDL is created

On December 15, 2025, the JPML created MDL 3163 for GLP-1 NAION cases. That gave the sudden-vision-loss topic its own federal litigation track separate from the larger GI-injury MDL.

The split also confirms that NAION should be treated separately from diabetic retinopathy and other eye-related questions.

April 1, 2026: current MDL counts show the scale difference

The April 1, 2026 JPML report showed 3,546 pending actions in MDL 3094 and 73 in MDL 3163. The gap in size matters because it confirms that GI injury remains the dominant federal GLP-1 litigation category by volume while NAION remains smaller but now real and distinct.

Those numbers show how much larger the GI track remains while also confirming that the NAION track is real and distinct.

2025 to 2026: the current label and research picture

The current February 2026 Wegovy label remains the backbone for severe GI reactions, pregnancy timing, gallbladder disease, retinopathy monitoring, the thyroid boxed warning, and the removal of suicidality language. The current Ozempic label remains the main product source for the diabetes-facing semaglutide track.

Current ophthalmology work and active ClinicalTrials.gov listings continue to move the evidence picture as well.

When To Seek Medical Care

  • This page is for chronology and context, not for diagnosing a current problem.
  • If the issue is acute GI distress, dehydration, sudden vision loss, or an allergic reaction, use the specific medical page and seek care first.
  • Use the timeline to understand what changed, then move into the topic page that best matches what happened.

FAQ

How is this different from the labels and studies page?+

The labels and studies page groups information by topic, while this page groups it by date so it is easier to see how the current landscape changed over time.

Why do dated updates matter so much on this topic?+

Because old screenshots, old label PDFs, and stale pages can become inaccurate quickly. The legal and safety picture changed materially across 2025 and 2026.

Does this timeline replace the more detailed medical pages?+

No. It is a chronology page. The medical and documentation pages still matter because they go much deeper into symptoms, records, and topic-specific source language.
