Safety
Important cautions
- In animal studies, liraglutide caused thyroid tumours. It is not prescribed to people with a personal or family history of medullary thyroid cancer.
- Stop taking and contact your doctor if you develop severe abdominal pain — this may indicate pancreatitis.
- Liraglutide can make your resting heart rate go up by about 2–3 beats per minute. Your doctor should keep an eye on this if you have a heart condition.
