What You Should Know About the Weight Loss Drug Saxenda

What is Saxenda?

One of the more interesting facts about Saxenda is that it is actually a high dose of the type 2 diabetes drug called Victoza. According to the Food and Drug Administration, both drugs “contain the same active ingredient (liraglutide) at different doses (3 mg and 1.8 mg, respectively),” although Saxenda is not prescribed for type 2 diabetes because its safety and efficacy for diabetes treatment has not been determined.

Saxenda works by imitating a hormone in the intestinal tract that signals the brain that your stomach is full. The drug is not a silver bullet, however, but an additional treatment option to be used along with a reduced-calorie diet and physical exercise.

Several other things are of interest about Saxenda, but first, let’s look at new findings concerning the drug.

Does Saxenda work?

The findings of a post hoc analysis of the three-year segment of a large trial (Satiety and Clinical Adiposity—Liraglutide Evidence, or SCALE) Obesity and Prediabetes trial were recently presented at the European Obesity Summit. Study participants were adults with prediabetes and obesity or a BMI of 27 or greater with risk factors.

A total of 1,505 individuals were given Saxenda and 749 took placebo for 160 weeks along with a reduced-calorie diet and an increase in exercise. The investigators’ findings (listed below) are important because they help clinicians predict which patients will likely experience long-term benefits by using Saxenda.

Individuals who took Saxenda who lost 5 percent or more of their body weight by week 16 (early responders) had more weight loss and improvements in cardiometabolic risk factors at week 160 compared with their peers who lost less than 5 percent of body weight by week 16 (early non-responders)At the 16th week, 68 percent of people taking Saxenda were early responders compared with 22.3 percent of people taking placeboAt the 160th week, Saxenda early responders (580 individuals) who finished the trial lost an average of 8.6 percent of body weight (20 lb/9.1 kg) compared with 2.9 percent (6 lb/3.1 kg) among early non-responders (210)Early responders to Saxenda also experienced improvements in glycemic factors, including reduced development of type 2 diabetes and regression to normal glycemic valuesEarly responders also had better improvements in systolic blood pressure and health-associated quality of life factors when compared with non-respondersRates of side effects between early responders and early non-responders were similar (97.1% vs 95.0%), with gastrointestinal problems being the most reported (75.3% vs 71.6%)Gallbladder disorders were more common among early responders (6.3%) when compared with early non-responders (2.2%)

Physicians can prescribe Saxenda for chronic weight management for individuals who are obese (body mass index [BMI] of 30 or higher) or overweight adults (BMI of 27 or higher) who have at least one weight-related condition (cardiometabolic condition) such as type 2 diabetes, high cholesterol, or hypertension. However, the drug should not be taken by anyone with diabetes who is already taking Victoza.

The price you may pay for taking this drug include the following side effects: increased appetite (exactly the opposite of what you want to happen!), constipation, diarrhea, low blood pressure, nausea, and vomiting.

On the more serious side, other adverse effects may include elevated heart rate, gallbladder disease, kidney problems, pancreatitis, and suicidal thoughts. The FDA has stated that anyone taking Saxenda who does not lose 4 percent of their body weight after taking the drug for 16 weeks should stop, because it’s unlikely Saxenda will work for them.

In addition:

For now, it’s not known whether use of Saxenda is effective or safe when taken along with other drugs (prescription or over-the-counter) or herbal weight-loss products. You should not use Saxenda and insulin togetherIt’s not known whether use of Saxenda has an effect on your risk of heart problems, stroke, or death due to heart problems or strokeDuring testing, Saxenda caused rodents to develop thyroid tumors, some of which were cancerous. It’s not known whether the drug will cause thyroid tumors or thyroid cancer (medullary) in humansSaxenda is not recommended for use in children
