Most people considering GLP-1 treatment have read the headline weight-loss numbers and very little about what taking the medication is actually like. This is the other half — written plainly, because the people who cope best with side effects are the ones who knew to expect them.
Semaglutide and tirzepatide belong to a class of medications that mimic hormones your gut releases after eating. They slow how quickly the stomach empties and reduce appetite signalling in the brain. Many people describe the effect as the constant background chatter about food going quiet.
That mechanism is also the source of most side effects. If digestion is slowed deliberately, the common consequences are digestive.
Nausea is the most frequently reported. It is usually worst in the first days after a dose increase and tends to ease as the body adjusts. Constipation is the second most common and often persists longer. Fatigue, reflux, burping and diarrhoea are also frequently reported.
The practical pattern most people describe: the first week on a new dose is the hardest, and each subsequent week is easier until the next increase. This is why clinicians titrate the dose upward slowly rather than starting at a full dose.
In SURMOUNT-1, a 72-week trial of tirzepatide in adults with obesity or overweight, participants on the 15mg dose lost an average of 20.9% of body weight. In STEP-1, a 68-week trial of semaglutide 2.4mg, the average was 14.9%.
Two things are worth being precise about. Those trials studied branded, FDA-approved products at specific doses alongside lifestyle intervention. Compounded medications are prepared by licensed compounding pharmacies and are not FDA-approved, and have not been through those trials. And an average is not a prediction: individual results in those studies varied enormously in both directions.
Weight change on these medications accrues over months rather than weeks, and the trials above ran for well over a year. Stopping early generally means giving back ground already paid for.
That is the practical argument for deciding the affordability question before starting rather than three months in. A treatment you cannot afford to finish is an expensive way to end up where you started.
Severe or persistent abdominal pain, particularly pain radiating to the back, persistent vomiting, signs of dehydration, or any symptom that is worsening rather than easing all warrant contacting a clinician promptly rather than waiting.
Tell your clinician about your full medical history before starting, including any personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2, any history of pancreatitis, and every medication you currently take.
Do not stop, start or change the dose of a prescribed medication on your own. This article is general information, not medical advice, and no article can substitute for a consultation with a clinician who knows your history.
Nausea is typically worst in the first days after starting or increasing a dose and eases as the body adjusts. Constipation often persists longer. Most people find side effects become more manageable over the first two to three months, though some do not and stop treatment.
Nausea is the most commonly reported side effect, followed by constipation. Both are consequences of the medication deliberately slowing how quickly the stomach empties.
No. Compounded medications are prepared by licensed compounding pharmacies and are not FDA-approved products. Ozempic and Wegovy are FDA-approved branded products made by their manufacturer. They are not the same thing and should not be treated as interchangeable.
That is a decision for the clinician managing your treatment. Research on stopping has generally found weight is regained after discontinuation. Do not stop a prescribed medication without speaking to a clinician.
