Plan for problems before they happen.

Ask about the common problems

The official information for semaglutide (Wegovy) lists feeling sick, vomiting, diarrhea and constipation among common side effects.

Fluid lost through severe vomiting or diarrhea can lead to kidney injury.

Understand the thyroid caution

Thyroid tumors found in studies of rats and mice are the subject of the boxed warning in official semaglutide information—the strongest warning used by the FDA.

It remains unknown whether people develop these tumors because of semaglutide.

The medicine information rules out treatment if your own health history, or your family’s, includes medullary thyroid cancer, a rare thyroid cancer.

People with MEN 2 also cannot receive treatment; this rare illness can be inherited by a child from a parent.

Treatment is also ruled out by a history of serious allergy to any semaglutide ingredient or to semaglutide itself.

Bring any family records of thyroid cancer or illnesses passed from parent to child.

Ask the doctor to check whether a diagnosis in those records is MEN 2; you do not need to identify it yourself.

Make your history part of the decision

The medicine information warns that belly pain that is severe or lasts, and may extend to the back, can signal serious swelling of the pancreas.

If this pain happens, contact the person treating you right away and describe it.

Pregnancy plans, eye disease linked to diabetes, other diabetes medicines and upcoming surgery are among the health details covered by the medicine’s warnings.
