The strongest label caution
Thyroid tumors in rats are the subject of the boxed warning on both tirzepatide labels. Among Food and Drug Administration (FDA) warnings, a boxed warning is the strongest.
It remains unknown whether people develop these tumors because of tirzepatide.
The labels say not to use it if your own medical history or your family’s includes medullary thyroid cancer, a rare thyroid cancer.
The labels also say not to use it with MEN 2, an uncommon illness inherited within families. They also say not to use it if you have a known serious allergy to tirzepatide or another ingredient.
Look for the name MEN 2 in your own or your family’s medical records, and ask the prescriber to check it.
If you do not know what a family diagnosis means, bring the record rather than trying to match symptoms yourself.
Stomach problems can need attention
Nausea, diarrhea, vomiting, and constipation were common problems in the Zepbound (tirzepatide) weight trials.
Stomach problems can be severe, and fluid loss has been linked to kidney injury.
The Zepbound label advises against it for severe gastroparesis, a condition that greatly slows the emptying of the stomach.
The label also describes gallbladder problems and inflammation of the pancreas, a gland involved in digestion.
The listed signs of pancreas inflammation include belly pain that persists or is severe and may extend into the back.
For pain like this, contact a medical professional now for help deciding where to go. Do not wait for a routine message reply.
Before treatment, ask how to reach medical help if the service is closed.
This page cannot examine you or decide whether your pain needs an emergency room.
Discuss pregnancy and birth control
Tirzepatide can make birth control pills less effective.
The Zepbound label tells prescribers to discuss added or different birth control protection when treatment starts and after each increase.
According to that label, these extra steps last 4 weeks after starting and after each increase.
That label also calls for stopping Zepbound when pregnancy is recognized.
Ask the prescriber to explain the label in terms of your own plans.
Tell the person treating you about other treatment
Taking tirzepatide alongside insulin or some diabetes pills can bring blood sugar too low, according to its labels.
They also flag complications in people with diabetic eye disease.
Food left in the stomach can enter the lungs during a procedure that uses medicine to put someone to sleep or make them deeply drowsy.
Ask the surgical team how your medicine affects the plan for the procedure.
