Why am I not losing weight on Saxenda?

It takes time to lose weight with Saxenda. In adults, it may take about 8 weeks before you start to see a significant weight loss (at least 5%) with Saxenda. In the first 2 to 4 weeks you may lose about 2% to 4% of your weight. You should also follow a long-term, reduced-calorie diet and exercise program as prescribed by your doctor for the best weight loss results.

Your dose is initially slowly increased over 4 to 5 weeks to help prevent stomach side effects like nausea, vomiting, diarrhea, and constipation. Tell your doctor if you have any side effects that bother you or do not go away.

Talk to your doctor, nurse, or dietitian about your weight loss plan if you need help sticking to your goals. They can help you make changes that can increase your success.

When will I start losing weight with Saxenda?

Some people starting losing weight in the first 2 to 4 weeks after starting treatment with Saxenda. In studies, significant weight loss of at least 5% was seen after 8 weeks of treatment. After one year of treatment in adults, 85% of patients treated with Saxenda lost weight (an average of 21 lb. [9.5 kg] weight loss, or 9.2% of their weight). Your results may be different.

You will follow up with your doctor within at least 16 weeks after starting Saxenda to see if it’s working well for you. If you have not lost at least 4% of your body weight at this time, your doctor may tell you to stop taking it. Even though patients may be doing everything they are supposed to, not everyone will lose enough weight on Saxenda to be able to stay on treatment.

There are other options for weight loss, including different medicines and weight loss surgery. Your doctor can discuss these choices with you.
