Key takeaways
- Two new once-daily GLP-1 weight loss pills won FDA approval, expanding options beyond injections.
- Both medications helped people lose weight and improve other weight-related conditions.
- The pills cost less than injectables and can cause similar side effects.
People prescribed GLP‑1 medications for weight loss now have options that do not require injections. Health regulators have approved two new GLP‑1 pills — one from the makers of Ozempic and Wegovy and another from the makers of Mounjaro and Zepbound.
Two new medications hit the market
This past December, the once-daily Wegovy pill was the first oral GLP-1 to gain federal approval for weight loss.
In clinical trials, participants who took the highest dose of the pill lost an average of 16.6 percent of their body weight (approximately 32 pounds for a 200-pound person) after 64 weeks, the drug’s manufacturer, Novo Nordisk, said in a Dec. 22 news release. One in 3 people taking the oral medication lost at least 20 percent of their body weight.
The pill is also approved to help reduce the risk of serious cardiovascular events like nonfatal heart attacks and strokes.
And on April 1, the Food and Drug Administration (FDA) approved Foundayo (orforglipron), a pill for adults with obesity or who are overweight and have a weight-related medical condition.
In clinical trials, participants who took the highest dose of the once-daily pill achieved an average weight loss of 12.4 percent, or 27.3 pounds, after 72 weeks, compared with 2.2 pounds with the placebo. Researchers found that the medication also helped to mitigate other health issues, such as high cholesterol and high blood pressure.
It’s worth noting that a GLP‑1 pill (Rybelsus) containing a much lower dose of semaglutide — the same active ingredient as Wegovy — has been approved by the FDA since 2019 to treat type 2 diabetes. Its weight loss effect, however, is far less pronounced.
What are the side effects of GLP-1 pills?
Novo Nordisk, maker of the Wegovy pill, says the side effects of the oral option are similar to the injectable version. Many participants in the trial reported gastrointestinal issues, such as nausea and vomiting, when taking the medication.
