Your Questions About Ozempic Answered by an Endocrinologist

As the popularity of Ozempic continues to rise, so do the questions surrounding its use, benefits, and potential side effects.

We have asked Endocrinologist Dr. Anne Peters, Director of the Clinical Diabetes Programs at Keck School of Medicine of USC, the most common questions about Ozempic from the Diabetes Strong community.

Are Ozempic and Wegovy the same drug? Can I switch between the two?  

Because Ozempic and Wegovy are the same drug (semaglutide), answers to the questions below are relevant for both brands.

Semaglutide works by mimicking the action of the hormone glucagon-like peptide 1 (GLP-1), which stimulates the pancreas to produce more insulin. More insulin helps sugar enter the cells, lowering blood sugar levels.

The main reason why semaglutide is effective in weight loss is that it increases the feeling of satiety and decreases appetite.

Is Ozempic the most effective drug for weight loss?

Semaglutide (Ozempic & Wegovy) is very effective for weight loss, but other options exist.

Studies have shown that people taking Ozempic experience an average weight loss of 10 to 15 percent.

In comparison, in clinical trials, people taking Tirezatide (Zepbound and Mounjaro) lost an average of 20 percent of their body weight.

Another difference between Ozempic and Tirezatide is that Ozempic is FDA-approved to reduce the risk of heart attack and stroke in people with type 2 diabetes, while Tirezatide is not.

Will I have to stay on Ozempic forever, or can I stop after losing weight and getting my A1c down?  

You should stay on the medication as long as you see good results and tolerate it without side effects. The medication only works as long as you take it.

What happens when you stop taking Ozempic?  

Always consult with your doctor before stopping a prescription medication. You should have a plan in place for gradually reducing the dose and an alternative way of managing the condition the drug is treating.

How common are Ozempic side effects?

The most common side effects of Ozempic include:
