What Are the Absolute Contraindications for Weight Loss Injectables?
MedExpress will not prescribe weight loss injectables such as Mounjaro® or Wegovy® if you:
Are pregnant or breastfeeding
Have a personal or family history of medullary thyroid cancer
Have a history of multiple endocrine neoplasia type 2 (MEN2)
Have previously had a serious allergic reaction to the medication or any of its ingredients
Have any other condition where treatment would be clinically unsafe
These situations present an unacceptable level of medical risk, which is why MedExpress does not prescribe Mounjaro® or Wegovy® in any of these circumstances.
What Other Safety-Related Exclusions Might Prevent Prescribing?
Beyond the absolute contraindications above, MedExpress prescribers may also avoid prescribing weight loss injectables in cases of:
Severe gastrointestinal disease
Uncontrolled or unstable medical conditions
Use of medications that conflict with, or make it unsafe to use, Mounjaro® or Wegovy®
Any factor that would prevent safe monitoring of treatment or safe adherence to it
MedExpress prescribers assess each of these cases individually rather than applying an automatic exclusion.
Why Are Contraindications for Weight Loss Injectables So Strict?
MedExpress's contraindications for Mounjaro® and Wegovy® are based on:
Clinical trial safety data
Regulatory prescribing guidance
Patient-safety standards
These safeguards ensure the benefits of treatment outweigh the risks before Mounjaro® or Wegovy® is prescribed.
