What happened

Novo Nordisk’s GLP-1 drugs face renewed NAION safety scrutiny, EMA labelling action and US litigation. The risk is relevant to India’s rapidly expanding ₹2,333

Key facts

  • 3 confirmed NAION cases among GLP-1 recipients versus 5 on inactive treatment
  • 96,829 people in pooled analysis
  • Over 58 million patient-years of post-marketing exposure
  • EMA: NAION may affect up to 1 in 10,000 semaglutide users
  • 216 US litigation actions pending as of September 1, 2026
  • India GLP-1 market: ₹2,333 crore MAT in August 2026
  • India semaglutide sales: ₹782 crore; tirzepatide sales: ₹1,456 crore

Why this matters

Potential GLP-1 partnerships or acquisitions in India warrant deeper diligence on pharmacovigilance, liability allocation and differentiation as generics expand distribution but intensify reputational exposure.
