Medullary thyroid carcinoma (personal or family history) or multiple endocrine neoplasia type 2: absolute contraindication. The rodent preclinical signal is real enough to exclude this population.

Severe hepatic impairment: less is known than for kidney disease. Extreme caution or contraindication depending on the specific degree of impairment.

Severe renal impairment (eGFR <15): these compounds are renally cleared and accumulate in severe kidney disease. Risk-benefit is unfavourable without dose adjustment.

f.ibarra, post #19: I read post #17 twice before replying, because I had assumed the opposite. Severe hepatic impairment: less is known than for kidney disease. Extreme caution or contraindication depending on the specific degree of impairment. Go to post

This follows post #26 rather than contradicting it.

Diabetic retinopathy complications: a signal for this was noted in SUSTAIN 6. Current evidence is mixed. The risk is not zero and some caution is appropriate in people with baseline retinopathy.

Picking up post #35: that is the part I would want checked first.

History of pancreatitis: these compounds can rarely trigger pancreatitis. History of pancreatitis increases relative risk. That is a relative contraindication, not absolute, but requires monitoring.

eire_reader, post #41: post #40 is right about the mechanism and I think understates the practical bit. Concurrent insulin or sulfonylureas: not an absolute contraindication but requires dose adjustment and close monitoring for hypoglycemia. The combination is used with caution, not avoided. Go to post

Coming back to post #71, because the follow-up matters more than the original answer.

Severe renal impairment (eGFR <15): these compounds are renally cleared and accumulate in severe kidney disease. Risk-benefit is unfavourable without dose adjustment.

On post #93 — agreed on the reasoning, with one qualification.

Severe hepatic impairment: less is known than for kidney disease. Extreme caution or contraindication depending on the specific degree of impairment.
