Tirzepatide tummy troubles - Sema a better bet?

3 months of feeling like crap on Sema and then switching to Tirz and feeling much better is the reverse of what the OP is dealing with. The individual variation in which direction causes more GI issues is genuinely unpredictable. Starting low and slow is the right advice regardless - 5mg on the second shot is a steep early entry.

Sema causing nausea and then having essentially no side effects from tirz, reta, and cagri is the opposite of what the OP is experiencing. The individual variation in which direction causes GI problems is genuinely unpredictable. 5mg on the second shot after starting is a steep early jump - what was the first shot dose?

The individual variation on nausea between sema and tirz is wide enough that general advice isn't very useful. The trial-and-see approach is genuinely the only way to find your personal response. If tirz was 10 days of nausea at 5mg, stepping back to a lower dose first would have been worth trying before concluding it doesn't work.

Sema hit me with rough GI issues, but Tirz has been noticeably gentler on the side effect front. Seems like a common pattern from what I've read from others too.

Always curious about this comparison. Started tirzepatide myself recently and the sides I noticed were limited to a bit of bloating and some brain fog the first couple days after each shot. Feels like tirz just comes with a lot going for it.

Started on Sema, worked up to the max recommended dose, then switched over to Tirz. Compounding pharmacy had me starting Tirz at 9mg coming off the 2.4 Sema. Weight started moving again, and I noticed way fewer side effects on Tirz. Sema gave me constant low grade nausea, Tirz gave me none, but bad constipation in the first weeks. Prunes daily fixed that within a short stretch. Still running Tirz, recently shifted from a seven day to a five day schedule trying to break through a stall, results still pending. Tirz was clearly the better fit for me, though everyone reacts differently. Personally think Tirz delivers more with fewer side effects.

Tirz made me sick. Haven't gotten sick on Sema yet, and I'm already up to 1.7mg there. Couldn't tolerate tirz once I hit .5 or whatever that second dose ended up being.

Would give tirzepatide a shot. Had brutal nausea all the way through 2.4mg on my previous medication. Switched over and had absolutely none.

Been on this myself, currently the third compound. My mom and two aunts run the single-pathway one, and just one aunt out of everyone got nauseated early on. Doesn't seem as common these days honestly. My husband started it, paused over bowel issues, later picked up a different GLP entirely, and hasn't had nausea on that one, nor was it an issue for him initially either. My close friend plus her kid and that kid's spouse all run the dual-action compound and none report nausea.

Not claiming it never happens though. Occasional random waves every few months that clear up quick with electrolytes.

Overall though, only one out of roughly eight people I personally know has experienced what I'd call genuinely extreme nausea. She's really sensitive to the medication and lost all her target weight at the two lowest doses. Early on she used to force herself to finish every plate, old habits from childhood, and once she finally stopped doing that, her nausea improved dramatically.

Tirz is the reverse for me, which helps since I have ulcerative colitis. What's interesting is how often side effect rates in studies differ from what people report on this forum. Early studies showed hardly any gap for tirz versus sema when it came to nausea and vomiting, yet online reports and newer papers lean toward tirz being easier. Same with reta: people online often mention odd skin sensations, but trials didn't show that much. Here people rarely bring up nausea or vomiting, whereas trials generally show at least half of participants having it to a notable degree.

Having run sema at 2mg and tirz at 15mg, I can say tirz has fewer side effects for sure. Still, with sema too the side effects fell off a lot once months 2 to 3 were over.

Same happened to me and it was awful. The weight came off, but I ended up badly undernourished. In the end the shots became unbearable, so I quit and the weight returned. Years later I tried tirzepatide, and none of that happens. Nothing beyond faint nausea the first day. Weight is dropping and I feel far better. Tirz is worth trying, in my view.

Swapping from microdosed sema to tirz went the opposite of badly for me. Ozempic topped out at 0.22mg every other day (about 0.8mg weekly) for tolerability, and pushing beyond 0.5mg weekly worsened both nausea and malaise, so I used tiny frequent doses for some hunger control, though nausea stayed considerable. I only began after losing 70kg. Tirz was easy, barely any nausea while I raised the dose, one episode of odd skin sensations. I stepped up 1mg every day or two to move quickly with lower risk, reached 15mg within a month, with way milder side effects, and hunger was lower compared with ozempic at 0.8mg weekly. GIP activity in tirz offsets nausea caused by the GLP-1 side.

Insurance made me start on semaglutide first and it hit me hard too, never improved the whole time, basically left me bulimic for a couple months. Eventually I got moved onto tirzepatide under the zepbound name, and it's been night and day, no more nausea, stomach trouble, or reflux. Worth asking your doctor about a few things if you're trying to push through. Omeprazole as a daily pill helped a lot with the nausea. Zofran too, those fast dissolving under-the-tongue tablets, my roommate works at a hospital and says they hand those out there, helped me a ton. For reflux, taking tums roughly an hour ahead of eating works well, though digestion runs slower on this stuff so you need to plan earlier than usual. Really sorry you're going through this, hoping it eases up soon.
