post #3 is right about the mechanism and I think understates the practical bit.

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

Coming back to post #14, because the follow-up matters more than the original answer.

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.

Allergy to the specific compound: true allergy is rare but possible. Any prior allergic reaction to the same compound or to structurally similar peptides warrants caution.

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.

Picking up post #41: 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.

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.

VThorvaldsen, post #8: post #7 answers the question as asked. The question underneath it is different. 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. Go to post

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

Worth separating two things that post #76 runs together.

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.
