Antibiotics and a course of something with delayed emptying

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

Supplements and herbs: many have no established interaction. Some do. If you are taking something unusual, checking a reference (like a pharmacist) is more useful than guessing from forum discussion.

Worth separating two things that post #14 runs together.

Separation timing versus clinically important interaction: a separation timing inconvenience (taking one medication 2 hours before or after another) is not the same as a clinically important interaction. Both can reduce absorption of one or the other, but only true interactions require active management.

Metformin: commonly co-administered and relevant to gastrointestinal tolerability. Gastrointestinal side effects can overlap and additive. Taking them separately or adjusting one if tolerability is poor are reasonable approaches.

Picking up post #45: that is the part I would want checked first.

Thyroid medications: semaglutide is associated with a slowing of gastric emptying, which might affect thyroid medication absorption if they are taken very close together. Separating them by a few hours is the conservative approach.

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.

Insulin interaction: semaglutide and tirzepatide are not contraindicated with insulin but the combination carries hypoglycemia risk if insulin doses are not adjusted. That is a reason for close monitoring, not for avoiding the combination.

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.

post #96 is right about the mechanism and I think understates the practical bit.
