Revisiting: Absolute versus relative contraindications posts 61–86
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.
Collapsed as off-topic by two members at trust level 3 or above
post #63 answers the question as asked. The question underneath it is different.
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.
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 #63 runs together.
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 #67 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.
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.
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.
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.
This follows post #70 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.
Pregnancy: these compounds are not approved for pregnancy. The potential risks outweigh potential benefits. Planning windows and washout (several months) are the standard approach.
On post #72 — agreed on the reasoning, with one qualification.
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.

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.
post #78 is right about the mechanism and I think understates the practical bit.
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 #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.
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.
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.
I read post #81 twice before replying, because I had assumed the opposite.
Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.
The correction was fair and I had been repeating something I had not checked carefully enough.
This follows post #81 rather than contradicting it.
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.
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.
post #85 answers the question as asked. The question underneath it is different.
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.
