This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

Gastroparesis or severe delayed gastric emptying: these compounds slow gastric emptying. Pre-existing severe gastroparesis can be worsened. That is a relative contraindication depending on baseline severity.

i.aranda_es, post #17: 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. Go to post

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.

post #32 answers the question as asked. The question underneath it is different.

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.

On post #30 — agreed on the reasoning, with one qualification.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.

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

Pregnancy: these compounds are not approved for pregnancy. The potential risks outweigh potential benefits. Planning windows and washout (several months) are the standard approach.

g.valckenaere, post #27: I read post #25 twice before replying, because I had assumed the opposite. Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive. Go to post

I disagree with the reply above, and I think the disagreement is substantive rather than terminological.

The distinction being drawn does not survive when you look at the published data for this specific question. I would be glad to be shown wrong on this, because the version I am arguing against is more convenient.

Worth separating two things that post #34 runs together.

Disordered eating history: appetite suppression can trigger relapse in people with history of anorexia, bulimia, or other eating disorders. This is a relative contraindication requiring specialist input.
