I was going off a graph I remember seeing in one of the studies where it showed a curve going up to a broad peak at about 2-4 months then declining, and was for nausea or vomiting. It was from a year or 2 ago so my odds of finding it again are not really that good, and would require looking through dozens of studies. At that point I was still on ozempic and not really enjoying the nausea that would not go away. The data in the graphs above look far more comprehensive and specific than my vague memory of the shape of a graph from one study, and a brief discussion in it on side effects and their timing. I am always happy to see accurate data, maybe even especially if it means I am wrong and can correct my knowledge defects. As I do not actually have to treat patients having a vague and mostly accurate memory of what I have read is usually adequate, but after looking at hundreds of papers over years there are going to be errors in my memory, and outdated data. And if looked up and provided references for every comment I made, I would be more precise, but it would take a lot of time.
I do wonder about the timing in those graphs. I found the surmount appendix and read the info under the graphs. They did start at 2.5mg and escalate doses by 2.5mg every 4 weeks. But it does not specify for sure the 15mg graph starts at the start or once that dose was reached, It does not really make sense to have the graph only start once the highest dose was achieved, but I would have though the side effects would be more spread out in time as doses went up, and maybe some peaks every 4 weeks for dose increases. For nausea and diarrhoea, but not vomiting the timing does seem to be more spread out up to 24 weeks for 10mg and not quite as clearly but for longer for 15mg. But it is still clear highest odds of side effects is after the first dose for GI effects. Which is useful information, and at odds with my statement earlier, as it suggests that early side effects might be a reasonable indicator of later side effects.
