Side effects are the number one thing people search about GLP-1 medications, and for good reason: most people feel at least some of them, especially in the first weeks or after a dose increase. The good news is that the common ones are usually mild, temporary, and manageable with a few simple habits. Here is an honest look at what is normal on compounded semaglutide or compounded tirzepatide, what actually helps, and the signs that mean you should message your provider right away.
The common ones (and why they happen)
GLP-1 medications slow down how quickly your stomach empties. That is part of how they reduce appetite, but it is also behind most of the early side effects:
- Nausea – the most common. Usually worst in the first day or two after a dose.
- Burping or “sulfur burps” – a known and harmless, if unpleasant, effect of slower digestion.
- Constipation or loose stools – gut motility changes in either direction.
- Bloating and heartburn – often tied to meal size and rich foods.
- Lower appetite and feeling full fast – the intended effect, but it can surprise people at first.
What actually helps
- Eat smaller meals. Large or fatty meals are the most common nausea trigger.
- Hydrate steadily. Dehydration makes nausea and constipation worse.
- Prioritize protein. It protects muscle while your appetite is lower – our protein calculator gives you a daily target.
- Go cold and bland when queasy. Cold foods smell less and often sit better.
- Give each dose increase time. Side effects usually settle within one to two weeks at a new dose.
When to message your provider
Most side effects are uncomfortable, not dangerous. But contact your care team promptly if you cannot keep fluids down, if you have severe or persistent stomach pain (especially pain that moves to your back), signs of dehydration, yellowing of the skin or eyes, or anything that feels sudden and intense. Severe abdominal pain can be a sign of pancreatitis or gallbladder problems and should never be waited out. Regular monthly follow-up consultations are built into your program so dose decisions and side-effect questions never have to wait.
The bottom line
Early side effects are common, usually manageable, and typically fade as your body adjusts. The people who do best are the ones who start low, go slow, eat smaller, and stay in touch with their provider. Have a question we did not cover?
