Personal or family history of medullary thyroid carcinoma — what changed since posts 61–90

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

Fair, and the limits you put on it are the part I will remember.

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.

e.ferreira, post #2: I had written a reply contradicting the opening post and deleted it. Here is what survived. 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. Go to post

Coming back to post #60, because the follow-up matters more than the original answer.

The general case is well covered; this is the awkward specific one.

This follows post #62 rather than contradicting it.

Somebody's condition being on a list does not settle the decision, and somebody's condition being absent from one does not either.

If anyone has run this properly I would rather read that than my own guess.

A history of pancreatitis appears in the cautions and the decision around it needs somebody who knows the history rather than a general rule.

Not a strong opinion, just a consistent one.

Somebody's condition being on a list does not settle the decision, and somebody's condition being absent from one does not either. I would rather say I do not know than round it up to an answer.

Where labelling has changed, the change is dated and public, and citing the current version is the whole of the discipline.

For what it is worth, the same held on the two occasions I checked.

Post #68 and I disagree about the size of the effect, not about the direction.

Adding it in case it saves somebody the afternoon it cost me.

eire_reader, post #41: Narrowing post #40, because the general version has more than one answer. Somebody's condition being on a list does not settle the decision, and somebody's condition being absent from one does not either. The disagreement above is smaller than it looks once the terms are fixed. Go to post

I had written a reply contradicting post #72 and deleted it. Here is what survived.

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.

Worth checking against a second source before it gets quoted onward.

Confirming post #72 from a second method, which matters more than confirming it from a second person.

That is my reading. Someone else read the same page differently and was reasonable.

Scoping that to what I have actually seen rather than what I have read.

Where I part company with post #78, and it is a narrow parting.

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.

Helpful, and short, which on this subject is harder than long.

Personal or family history of medullary thyroid carcinoma, or multiple endocrine neoplasia type 2, is the clearest contraindication in this class and it is specific rather than general.

It is a small point and it changes the answer, which is an awkward combination.
