These products carry a boxed warning regarding thyroid C-cell tumours observed in rodent studies, and are contraindicated in people with a personal or family history of medullary thyroid carcinoma or MEN 2. Read the full prescribing information for your specific product and discuss it with your prescriber — this summary is not complete and is not a substitute for that document.
Most gastrointestinal effects are reported as being worst in the days after a dose increase and easing as the body adjusts, which is the reason the titration schedule is stepped rather than immediate. Anything severe, persistent, or unexpected is a reason to contact your prescriber rather than to look for an answer online.
