Someone on a discussion forum asked whether taking amitriptyline (brand name Endep) while using semaglutide drugs like Wegovy or Ozempic could have caused a big weight regain. They described previously losing a lot of weight on Ozempic, then starting Endep for nerve pain and putting much of the weight back on. After switching back to Wegovy they say the weight stopped rising but hasn’t come off, and they want to know if the drug combo is to blame. Amitriptyline is an older antidepressant that’s also used for nerve pain. It changes several brain chemical systems and can make people feel hungrier or slower to burn calories. Semaglutide (the active drug in Ozempic and Wegovy) is a newer injectable medicine that acts like a natural gut hormone to reduce appetite and slow stomach emptying, which helps many people eat less and lose weight. So one drug tends to increase appetite, and the other suppresses it — that’s the basic tug-of-war. The report here is just a single person’s account on a forum, not a controlled study. Personal stories are helpful but can’t prove cause and effect. There are clinical studies showing amitriptyline and other tricyclic antidepressants are associated with weight gain in some people, and separate high-quality trials showing semaglutide causes significant weight loss on average. But there aren’t large, definitive studies that specifically measured what happens when people take amitriptyline together with semaglutide. The forum post suggests a plausible interaction — the appetite-increasing effect of amitriptyline could blunt semaglutide’s benefits — but we can’t be sure from one report. What matters for most people is practical: if you’re on semaglutide and start a medication like amitriptyline and then gain weight, it’s reasonable to suspect the new drug might be contributing. That doesn’t mean it will happen to everyone. Doctors often balance treating pain or depression against possible side effects. If weight control is an important goal, clinicians can consider alternatives for nerve pain, adjust doses, add behavioral strategies, or monitor more closely. It’s also worth remembering exercise and calorie tracking sometimes need tweaking when medications change. Be cautious: amitriptyline has known side effects like drowsiness, dry mouth, and weight gain for some people. Stopping or changing either drug should only be done under medical supervision. Also, forum posts don’t replace medical advice; they can point to issues to raise with your prescriber. If weight has rebounded a lot or you’re struggling to lose while on semaglutide and taking another medication, talk to your doctor about the possibility of drug effects, alternatives, or referrals to a specialist. Bottom line: It’s plausible that amitriptyline could reduce the weight-loss effect of semaglutide for some people, but a single forum report isn’t proof — discuss options with your clinician.
