As the Ministry of Food and Drug Safety (MFDS) pursues the designation of GLP-1 obesity treatments as 'drugs of concern for misuse and abuse,' it has released an analysis showing that the public interest benefits of protecting citizens' rights to know and to health are significant.

Consequently, GLP-1 obesity treatments containing liraglutide, semaglutide, and tirzepatide are highly likely to be designated as drugs subject to concern for misuse and abuse following a collection of industry opinions. Once designated as a drug subject to concern for misuse and abuse, warning phrases will become mandatory on packaging, and sales without a prescription will be prohibited even in areas exempt from the separation of prescribing and dispensing.

The MFDS issued an administrative notice on the 5th regarding a partial amendment to the "Regulations on the Designation of Drugs Subject to Concern for Misuse and Abuse," which features these primary measures. The MFDS has also concluded its economic and social feasibility review through a regulatory impact assessment report.

6.3-fold increase in supply...severe safety insensitivity including inappropriate prescribing for pediatrics and pregnant women

The background of the MFDS is to tighten regulatory oversight, which lies in the recent explosive growth of the obesity treatment market and the resulting indiscriminate misuse and abuse.

According to the regulatory impact assessment report, the volume of GLP-1 receptor agonist obesity treatments (liraglutide, semaglutide, and tirzepatide) imported and supplied domestically increased by 6.3-fold (approximately KRW 901.0 billion) in just one year, skyrocketing from around KRW 169.9 billion in 2024 to approximately KRW 1.0709 trillion in 2025.

The problem is that instances where these medicines are abused for simple cosmetic weight loss by individuals with normal body weights or are illegally distributed are surfacing consecutively. In fact, it was verified that 69 cases of inappropriate prescribing occurred for pediatric patients under the age of 12 and 194 cases for pregnant women. At the same time, crackdowns by relevant authorities revealed a sharp increase in the detection of online false or exaggerated advertisements and illegal distribution.

Notably, pharmacy supply volumes in 'areas exempt from the separation of prescribing and dispensing', such as remote islands and mountainous regions lacking physicians, have also experienced a steep spike. For the flagship product 'Wegovy', supply volume to pharmacies in these exempt regions increased by 975.7% year-over-year.

History of Designations for 'Drugs Subject to Concern for Misuse and Abuse'

There are two core measures newly established through the introduction of this regulation.​ First, it restricts the sale of these obesity treatments so that they can be dispensed only upon a physician's prescription at pharmacies nationwide, including those located in areas exempt from the separation of prescribing and dispensing. The intent is to block indiscriminate acquisition channels that bypass prescriptions fundamentally.

Second, pharmaceutical manufacturers and importers must clearly print the phrase "Drug Subject to Concern for Misuse and Abuse" on product containers, packaging, and package inserts. Through this, the agency plans to heighten awareness regarding drug misuse and abuse among both medical professionals and consumers.

Direct costs to the pharmaceutical industry estimated at KRW 24 Million... "Public interest benefits overwhelmingly outweigh compliance costs"

The MFDS found that the economic burden imposed on the pharmaceutical industry by this regulation remains marginal. Currently, there are a total of 24 authorized obesity treatment products containing the relevant active ingredients in South Korea. Upon calculating the costs of modifying labeling materials, such as replacing printing ink and copper plates, for the 12 items currently launched and actively selling in the market, it was estimated that a one-time direct cost of approximately KRW 2 million per product, totaling KRW 24 million (equivalent to an annualized net cost of KRW 2.9 million), would be incurred. Six products that have not yet been launched were excluded from the cost-incurring factors.

The MFDS emphasized, ​"Compared to private losses such as material modification expenses for certain regulated entities or revenue declines for pharmacies, the public interest benefits of preventing side effects from inappropriate drug administration and protecting the citizens' right to know and right to health are significant."

The MFDS plans to gather both positive and negative opinions on this administrative notice through June 26, 2026, and to implement the policy immediately. Consumers and the industry will be granted a one-year transitional grace period to use pre-manufactured packaging materials produced before the implementation date.
