Contraindications Deep-Dive: Who Should Not Be Prescribed a GLP-1
Not everyone is a candidate for GLP-1 therapy. Here's a clear-eyed look at the contraindications and cautions that should factor into a prescribing decision.
Absolute or strong contraindications
- Personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) — standard screening questions for this drug class
- Known hypersensitivity to the specific medication or its components
- Active pregnancy or breastfeeding
Conditions requiring careful clinical judgment
- History of pancreatitis — requires individualized risk assessment
- Severe gastrointestinal disease, given the mechanism's effect on gastric emptying
- History of gallbladder disease, given documented associations with GLP-1 use
- Active eating disorder — requires careful clinical judgment given the medication's appetite-suppressing effect
Clinical note: A thorough intake should explicitly screen for each of these, not just ask generically about "any medical conditions." The specificity of the screening is itself a marker of evaluation quality.

What patients should do
Be fully forthcoming about personal and family medical history during intake, even details that seem unrelated — the MTC/MEN 2 family history question specifically is easy to overlook if you're not aware of why it's being asked.
