A person posted on Reddit saying they felt anxious while taking tirzepatide (often sold as Zepbound or Mounjaro) or a brand they called Reta, but not when they took semaglutide (sold as Ozempic or Wegovy). They're asking if others had the same experience and whether switching to semaglutide might help with anxiety. This is just a brief online question from one user, not a scientific study. Tirzepatide and semaglutide are both injectable medicines used mainly for diabetes and weight loss. Semaglutide mimics a natural gut hormone that tells your brain you’re full and slows stomach emptying. Tirzepatide does that too, but it’s a “dual” drug: it acts like two different gut hormones at once. Both change appetite and digestion, but they aren’t antidepressants or anti-anxiety drugs. What the Reddit post shows is an individual report, which is useful for starting conversations but not solid evidence. Single-person reports can’t tell us how common a side effect is or whether the drug actually caused it. Clinical trials and larger studies are better for that. Trials have recorded mood and nervous-system side effects for these drugs, but results vary. Some people do report anxiety or jitteriness on tirzepatide, and others report similar feelings on semaglutide — while many people have no mood changes at all. The post doesn’t give details like dose, other medications, medical history, or how long the symptoms lasted, so we can’t draw reliable conclusions. For someone who notices anxiety on one of these medications, it matters because switching drugs might help, or the feeling might go away on its own. People who’ve experienced anxiety on tirzepatide might want to talk with their prescriber about trying semaglutide instead, adjusting the dose, or monitoring symptoms more closely. Clinicians will weigh benefits (blood sugar control, weight loss) against side effects and personal history, like whether you have a history of anxiety disorders. Caveats are important. These reports don’t replace medical advice. Both drugs can cause other side effects like nausea, stomach upset, and rarely more serious problems. If you’re on psychiatric medications or have a history of mood disorders, discuss any changes with your doctor — stopping or switching medications without professional guidance can be risky. Also, availability, cost, and insurance coverage differ between drugs, and only a clinician can decide if a switch is appropriate for you. Bottom line: One Reddit user said tirzepatide made them anxious but semaglutide did not—an interesting anecdote, but not proof. If you’re experiencing anxiety on one of these drugs, talk to your healthcare provider about options.
