Overview

• Nikki Cuthbertson, 34, says she bought tirzepatide injections online from November 2024 and increased her dose to 15 mg, losing about seven stone by July 2025.
• She developed severe chest pain and later vomited brown liquid before being taken by ambulance to Royal Stoke University Hospital.
• Ultrasound and MRI scans showed gallbladder inflammation and stones with liver inflammation and sepsis, leading to laparoscopic gallbladder removal.
• She has since stopped the medication and urges others to research potential side effects, saying she now feels unwell after eating fatty foods.
• Mounjaro’s leaflet lists gallstones as common and gallbladder infection as uncommon, and manufacturer Lilly urged patients to consult clinicians and ensure they receive genuine medicine.
