Care checks / clear signals
Side effects, product quality and urgent symptoms are different problems. Put each one in the right lane.
A guide cannot tell what a symptom means for one person.
Start with the label
Labels checked in September 2026 for semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound) and liraglutide (Victoza, Saxenda) listed nausea, diarrhea, vomiting and constipation among common effects. How many people had these problems differed by product and study.
Those labels also warned about serious problems. These included an inflamed pancreas or gallbladder. They also included kidney harm after dehydration and a severe allergic reaction. These medicines slow how fast the stomach empties. Food left in the stomach could get into the lungs during surgery or a procedure where you are put to sleep with medicine. The labels ask patients to tell the surgery team first that they take it.
The same September 2026 labels called attention to personal or family thyroid cancer history, serious stomach problems, pregnancy, diabetes medicines, eye disease, pancreas or gallbladder history, and planned procedures.
Emergency
Struggling to breathe, a swollen face or tongue, fainting, hives spreading over the body or difficulty swallowing can signal anaphylaxis. Anaphylaxis means a life-threatening allergic reaction.
For severe anaphylaxis symptoms, phone 911 or your local emergency line.
Medicine mistake
For a mistake with medicine, Poison Control offers free and private help all day and night.
Do not wait for a website reply when urgent help is needed.
Warm delivery
As of September 2026, FDA advised not using a GLP-1 shot that arrived warm or without enough cold packs, because heat can spoil the medicine.
Use the contact path supplied by the pharmacy or clinician to report the problem.
Online care checks
Nothing saved yet.
Compounded is not the same as approved
As of September 2026, no compounded drug carried FDA approval, and FDA had not confirmed that any was safe, effective or well made before it went on sale.
By September 2026, FDA had also received reports of people taking the wrong amount of compounded semaglutide shots, and some ended up in hospital. Most often, people drew too much liquid from a bottle meant for several shots.
This guide does not explain how to measure a dose or mix a medicine. Ask the clinician who prescribed it or the pharmacist who filled it about the amount, the pen or syringe, or the label. Call Poison Control if a mistake has already happened.
Make help easier
Show the label to whoever is helping you, such as Poison Control, your clinician or an emergency team. It gives the drug name, the maker and whether it is a pen, a small bottle for shots, or a pill. Note what happened and when. Use the urgent routes above when the signs are severe.
Write the symptom, when it began, and who you called. Clear facts help the next person understand the problem.
Where the warnings come from
The product-specific claims come from current FDA labels. The emergency wording comes from MedlinePlus and Poison Control.
