Weight loss is no longer a privilege! Eli Lilly’s oral weight-loss drug Foundayo is now上市, with a price that’s only猛健樂 15%

The competition in the U.S. weight-loss drug market is heating up again. Eli Lilly’s oral weight-loss drug Foundayo has received FDA approval and is being launched today (the 6th). Outsiders are praising it as a “powerful sibling drug” of the hit medication Mounjaro, saying that an oral option will let audiences who don’t dare to get injections also sign on. Vincent, co-founder of Man Bao, believes that Foundayo’s launch allows both doctors and patients to choose drugs that fit their own needs (whether weight-loss goals or medical expenses).

Outsiders expect Foundayo to directly take on the oral version of Wegovy that Novo Nordisk is set to roll out earlier this year. The difference is that Wegovy must be taken in the early morning on an empty stomach, and after taking it, you have to wait a while before you can eat; meanwhile, Foundayo can be taken anytime. On pricing, Foundayo is only 15% of Mounjaro, but its effects are also somewhat weaker than Mounjaro and Wegovy.

If you had to judge in one sentence: if you’re chasing results, you can use Mounjaro. If you’re chasing price, oral Wegovy and Foundayo are both much cheaper. Foundayo’s 72-week clinical weight-loss results are slightly weaker than Wegovy’s, but its advantage is that it’s more convenient to use.

This article will comprehensively compare the clinical evidence for weight-loss effects and pricing among Foundayo, Mounjaro, and Wegovy.

What is oral weight-loss drug Foundayo?

The newly approved Foundayo (generic name orforglipron) is a once-daily oral GLP-1 receptor agonist, and is seen as an important milestone in the weight-loss drug market shifting from “injectables” to “oral medications.” Compared with traditional products that require injection, the oral formulation greatly lowers the barrier to use. The market expects it will attract a broader patient population and further expand the overall market size.

Outsiders believe Foundayo will directly compete with the oral version of Wegovy that Novo Nordisk launched earlier this year. The two companies’ competitive focus has also shifted from the past injectable star drugs to more convenient oral therapies. There is a clear contrast with Novo Nordisk’s oral Wegovy, which must be taken in the early morning on an empty stomach and followed by a waiting period before eating. Foundayo can be taken at any time during the day and does not require fasting or restrictions on drinking water and eating.

Its relationship with Mounjaro is this: both come from the same company, Eli Lilly, and both are weight-loss/metabolic-therapy products in the incretin system, but they are not the same drug. Mounjaro is a weekly injected tirzepatide and is a dual GLP-1/GIP receptor agonist. Foundayo, on the other hand, is an oral weight-loss drug that is GLP-1–dominant. It’s a different formulation and belongs to a different product line.

Foundayo, Mounjaro, and Wegovy—effect and price fully explained

Clinical trials show that patients using the highest dose of Foundayo averaged about a 12% weight loss over 72 weeks, slightly less than oral Wegovy’s approximately 17%, but it still has significant effects. However, Foundayo has fewer usage restrictions and is easier to use, and is considered to have an advantage in commercialization potential.

Reuters reported that Foundayo’s self-pay starting price is $149 per month, but most patients actually pay about $349. If prescriptions are continued on schedule, it can be reduced to about $299. The self-pay price for oral Wegovy from Novo Nordisk starts at $149 and is about $299 for higher doses. The U.S. list price for injectable Wegovy is as high as $1,349.

Where to buy Mounjaro in Taiwan? What’s the monthly price?

Under this benchmark, overseas websites state that Mounjaro costs about $1,000 per month. In Taiwan, pricing is usually based on dosage, and the price varies significantly from one location to another. For example, at Tzu Chi Hospital, 10mg costs NT$13,200, not including needles, registration fees, and other expenses. You can refer to the “Mounjaro Friends Club” compiled by netizens. Just note that in Taiwan, Mounjaro is a prescription drug, so you need a prescription to purchase it. Netizens say that when you go to see a doctor at a hospital or clinic, doctors typically only prescribe when BMI is greater than 27 or 30.

From administration method to financial burden, Foundayo gives patients and doctors more options

Over the past week, Eli Lilly, the parent company of Mounjaro and Foundayo, has seen its stock price rise by more than 6.53%. Many analysts believe that oral weight-loss drug Foundayo will become a new engine driving the company’s revenue.

Vincent, co-founder of Man Bao and a former J.P. Morgan executive director focused on pharmaceutical research, believes that rather than calling it a “sibling drug to Mounjaro” or an “oral slimming injection,” it’s more accurate to say it gives patients more choice in optimizing treatment plans (administration method + financial burden).

He pointed out that this is the first “non-peptide small-molecule GLP-1” (different from both Wegovy and Mounjaro), and because of manufacturing-cost advantages, Lilly is very likely to adopt more aggressive pricing either to target mass market or as a maintenance treatment after finishing the injectable course. It also gives doctors and patients more freedom to customize treatment options according to their own needs (whether weight-loss goals or medical expenses).
