Absolute and relative contraindications, and the conditions that change the calculus.

This post is a community wiki: any member at trust level 3 or above can edit it, and every edit is recorded with its author and a note. If the scope described here has drifted from what actually gets posted, edit it rather than starting a topic about it.

What belongs here

  • Questions specific to contraindications, with the units and the context stated.
  • Reports and datasets, with the collection method stated.
  • Disagreement about the substance, conducted in public.

What belongs elsewhere

  • Anything urgent belongs in Safety, immediately, and not here.
  • Anything about how this site works belongs in Meta.
  • Requests for a maintained page belong in Wiki requests.

Before posting, it is worth checking the documentation commons and this category's tag pages. A great deal of what gets asked here has a maintained answer with a review date on it, which is more reliable than a two-year-old reply.

Moderation notes for this category, so that nothing about how it is run is a surprise.

Topics get moved into and out of here regularly. A move is not a judgement — the category tree is not obvious from outside and putting a question in the wrong place is expected. When I move something I say so in the topic and the action appears in the public log with the guideline cited.

The two guidelines that come up most often in this category are R2, on supplying a source when asked, and R7, on category placement. Neither is used punitively.

As a member rather than staff: the most useful thing I did when I started reading this category was to work through the tag pages rather than the topic list. The topic list shows you what is recent. The tags show you what is settled.

Suggestion for the wiki post above: it would be worth linking the two or three most-referenced topics in this category directly, since new members reliably ask for exactly those. Happy to make the edit myself if nobody objects, with a revision note.

Research-use-only material has no labelling and therefore no contraindications listed, which is not the same as having none.

That is where I would start, not where I would stop.

Post #5 is the version of this I will quote in future. One addition.

Interaction-based contraindications are compound-pair specific and are the ones most often generalised incorrectly.

This is the version I would want a new member to read first.

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.

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

Happy to be the one who is wrong here if it settles the question.

No notes. Posting so the count is not one.

Building on post #8 rather than restating it.

The section of the product information covering special warnings is usually longer and more useful than the contraindications list itself.

The rule of thumb is fine; the edge cases are where it earns its keep.

Reading the contraindications section of the actual product information takes two minutes and answers most questions asked here.
