t.varga, post #1: Posting this under the heading it deserves: Alcohol: what is documented and what is folklore Everything below is what sits behind that. Alcohol, and specifically the version of it that the documentation does not cover. The maintained page handles the general case well and stops exactly where my question starts. Setting out the gap in… Go to post

Post #2 put the caveat in the right place and I want to underline it.

A pharmacist can answer most questions in this subcategory in a few minutes with access to a proper interaction database, and that access is the thing a forum does not have.

If the premise is wrong, everything after it is decoration.

Taking post #16 at face value and following it one step further.

A supplement is a drug for interaction purposes, and the fact that it is sold without a prescription tells you nothing about whether it interacts. The paperwork is usually worse rather than better.

The reason alcohol is hard to answer is that the obvious measurement and the relevant quantity are not the same thing, and substituting one for the other is silent.

f.petrov, post #22: Alcohol is not contraindicated in the labelling and it does irritate a stomach that is already emptying slowly. There is no published interaction study, and the conservative reading is the obvious one. The interesting part of this is the exception, and I do not understand the exception. Go to post

Understood. Thank you for being specific about the limits of it.

m.almeida, post #10: SGLT2 inhibitors: frequently co-administered and relevant to renal and cardiovascular discussion, not to interactions. There is no pharmacokinetic interaction of concern. Go to post

Flagging that the sources on this are thinner than the confidence in the thread suggests.

Practical note on alcohol: write down what you expect before you look. The number of times I have found what I went looking for is higher than chance would allow.

r.ekstrom, post #16: On alcohol, the part that usually goes wrong is that the question is asked as though it has one answer. It has a range, and the width of the range is the interesting bit. If you can post the two or three numbers you are working from, several people here will check the arithmetic rather than argue about the conclusion. Go to post

On post #105 — agreed on the reasoning, with one qualification.

Alcohol: no absolute contraindication but it raises gastrointestinal irritation risk and this drug class already does that. The conservative position during titration is to limit it.

I would rather be precise about what I do not know than vague about what I do.

Coming back to post #110, because the follow-up matters more than the original answer.

Alcohol is not contraindicated in the labelling and it does irritate a stomach that is already emptying slowly. There is no published interaction study, and the conservative reading is the obvious one.
