Hepatic impairment and the absence of data

Hepatic impairment and the absence of data — setting out what I have, and where I think it stops being reliable.

Asking about a population rather than about a person.

The published trials in this class mostly enrolled a fairly specific group, and the questions here frequently come from people well outside it. I would like to understand what the honest position is when someone falls outside the studied population: not "it is fine" and not "there is no data", but what the reasoning actually looks like.

Renal impairment: the compounds are cleared renally to some degree. Dose adjustments might be needed in severe renal impairment. Consulting with a clinician familiar with renal dosing is prudent.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.

post #2 answers the question as asked. The question underneath it is different.

Pregnancy and planning: these compounds are not approved for use in pregnancy. Planning windows (how long to wait before attempting pregnancy) are not formally established. Conservative approaches wait several months to allow clearance.

I read post #3 twice before replying, because I had assumed the opposite.

Older adults: sarcopenia risk is higher, polypharmacy is common, and the clinical trials did not enroll many people over 75. Extrapolating to very old people is extrapolating beyond the data.

Gastroparesis: pre-existing severe delayed gastric emptying can worsen with compounds that slow it further. Discussion with a clinician is prudent if this history exists.

Medullary thyroid carcinoma history: an absolute contraindication because of the preclinical findings in rodent toxicology. The history (personal or family, especially multiple endocrine neoplasia type 2) is an important screening question.

Coming back to post #7, because the follow-up matters more than the original answer.

Picking up post #7: that is the part I would want checked first.

Disordered eating history: a history of anorexia nervosa, bulimia, or other eating disorders changes the risk-benefit calculation because appetite suppression might trigger relapse. This population requires specialist input.

Hypoglycemia risk: in people already on insulin or sulfonylureas, adding a GLP-1 agonist requires insulin dose reduction and close monitoring for hypoglycemia. This is manageable with attention.

Coming back to post #10, because the follow-up matters more than the original answer.

Pancreatitis history: the compounds can rarely trigger pancreatitis. A history of pancreatitis makes monitoring for recurrence more important during titration.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

Adolescents: a distinct evidence base exists. The compounds are not approved for routine adolescent obesity but are being studied. Adolescent physiology and psychology differ from adults' in ways that matter for this medication class.

This follows post #12 rather than contradicting it.

Thank you for the correction. I have edited my earlier post with a note rather than silently, so the thread still makes sense to read. The error was mine and it was the kind that comes from remembering a figure instead of looking it up.

Hepatic impairment: less is known about dosing in significant liver disease than in kidney disease. Extreme caution applies because the liver metabolises a large fraction of many medications.

Worth separating two things that post #23 runs together.

post #27 is right about the mechanism and I think understates the practical bit.

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.
