Novo Nordisk has launched its weight-deficit drug Wegovy in China after it was approved by local health authorities in June.

It is set to intensify competition with rival Eli Lilly, whose popular weight-deficit treatment also got the green light months ago but has yet to leave on sale in the globe’s second largest pharmaceutical trade.

More than 180 million people live with obesity in China, which has a population of 1.4 billion.

According to Chinese business information website Yicai, a dose of four Wegovy injections will expense 1,400 yuan (£153; $194), a fraction of the drug’s worth in the United States.

Yicai’s update says patients in China will have to pay the packed worth for the treatment, as the drug has not been included in the national healthcare insurance.

Research suggests that Wegovy patients can misplace more than 10% of their body weight.

In a post on Chinese app, WeChat, Novo Nordisk said its treatment “will provide a secure and effective weight deficit alternative for overweight and obese patients in China”.

Aimed at people who are severely overweight, Wegovy’s energetic ingredient is a medicine called semaglutide, which helps control blood sugar, lowers appetite, and makes patients feel fuller. It is also the energetic ingredient in sister drug Ozempic, which is used to treat type 2 diabetes.

However, there can be side effects for some users, such as nausea and vomiting, and research shows that patients often put weight back on after stopping treatment.

Wegovy went on sale in the US in 2021 where a month’s supply currently costs $1,349.

Fuelled by a social media buzz and celebrity users including Elon Musk, the drug has since been flying off pharmacy shelves around the globe.

The UK’s Medicines and Healthcare products Regulatory Agency has asked doctors to be alert for patients who may be misusing obesity injections, such as Wegovy.

It followed reports that some people who were not obese became ill, after using the jabs for weight deficit.

Wegovy’s popularity has turned its maker, Novo Nordisk, into Europe’s most valuable corporation. It currently has a total trade worth of of more than $440bn.
