For many people in Germany living with obesity, Ozempic (semaglutide) has been of help. Originally designed to treat type 2 diabetes, Ozempic also helps reduce appetite and support weight loss. However, some patients find that after a few months, their progress slows, or even stops completely.
How come Ozempic isn't working for you anymore? We'll explain what are the possible reasons for Ozempic to become less effective over time, as well as list some of the options you may have at this point. As always, any treatment decisions should be taken together with your doctor.
Why Ozempic may stop working
Many patients see significant weight loss in the first few months of using Ozempic. But in some cases, the effect seems to level off. Here are some common reasons why:
1. Your body has hit a natural plateau
Weight loss naturally slows down as your body adapts. When you lose weight, your metabolism slows, and your calorie needs decrease. This is known as adaptive thermogenesis - your body’s way of protecting itself from further weight loss. It’s not a failure - it’s biology 1.
According to Dr. Mir Ali from the MemorialCare Surgical Weight Loss Center, patients tend to reach a plateau with semaglutide (which includes Ozempic, but also Wegovy) when they are close to a healthy weight - usually at about 60 weeks of treatment 1. This timeline will clearly vary from one patient to another, but at one point or another you will reach a plateau, and that's ok.
2. You’ve adjusted your habits
Ozempic can help reduce hunger, but over time, your body might get used to the medication’s effects. You may gradually start eating more without realizing it, or reduce your physical activity once some weight is lost. Even small changes in behavior can impact your results 2.
3. You’re building tolerance to the medication
Some patients may develop a tolerance to semaglutide over time. The same dose that worked initially may no longer produce the same appetite-suppressing or metabolic effects. In such cases, adjusting the dose or switching medications might help 1.
However, there is a maximum dose of semaglutide you can take, and if you're already at that level and have reached a plateau, then you would need to discuss alternative options with your doctor.
What are your options if Ozempic stops working?
If Ozempic no longer helps you lose weight, there are several safe and legitimate options to discuss with your doctor. For example:
1. Adjusting your medicine dose
Sometimes, your doctor may recommend adjusting the dosage or timing of your semaglutide injections. If this is an option in your case, a consultation with your treating doctor will help you find a solution.
2. Reviewing your lifestyle
This might sound obvious, but if you've let your diet or physical activity slip, getting back on track with them could support you in moving past the Ozempic plateau. Also important is to make sure you're sleeping enough, and minimizing stress.
3. Switching to a different weight-loss medicine
If your body is no longer responding to Ozempic, your doctor may suggest trying a different medicine with a different mechanism of action. Some available options include:
Wegovy (semaglutide in a higher dose) Specifically approved for treating obesity, Wegovy has been shown to lead to up to 15% body weight loss. It’s similar to Ozempic, but taken at a higher dose.
Mounjaro (tirzepatide) This medicine combines GLP-1 and GIP receptor activity, which may lead to greater weight loss than semaglutide alone. Whether Mounjaro could be an option for you is for your treating doctor to determine.
Saxenda (liraglutide) Unlike Ozempic, which is a weekly injection, Saxenda is a daily injectable GLP-1 receptor agonist approved for weight loss. Some patients may benefit from smaller daily doses, making Saxenda a potential Ozempic alternative to discuss with your doctor.
Mysimba (naltrexone/bupropion) Also known as Contrave in other markets, Mysimba is a tablet taken daily that works on the brain’s reward system to reduce cravings. It’s often helpful for those who struggle with emotional eating or compulsive snacking. If this is your biggest hurdle when trying to lose weight, Mysimba's different mechanism of action may be a suitable alternative to GLP-1 or GIP receptor agonists.
Note: Always talk to your doctor before switching medicines. Not all medicines are suitable for everyone, and your medical history will help determine what’s best.
