Second pass at: Pregnancy and pregnancy planning: contraindication and washout posts 31–60

I read post #43 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.

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.

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.

post #47 is right about the mechanism and I think understates the practical bit.

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.

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.

Picking up post #47: that is the part I would want checked first.

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.

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.

Worth separating two things that post #48 runs together.

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.

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.

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

On post #52 — agreed on the reasoning, with one qualification.

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.

Picking up post #54: that is the part I would want checked first.

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.

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.

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.
