FDA says its review of a Web site maintained by Hua Da Trading in Brooklyn, NY, determined the firm takes orders for its “WeFun” product which is considered by FDA to be an unapproved and misbranded drug, even though the firm markets it as a dietary supplement. A 12/20/2023 [Warning Letter](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/warning-letters/hua-da-trading-inc-664359-12202023?ref=fdaweb.com) says a laboratory analysis of a sample of WeFun confirmed that it contains the undeclared pharmaceutical ingredient sildenafil, the active ingredient in Viagra, used to treat erectile dysfunction.

The letter says that although the product’s labeling indicates it is a dietary supplement, supplements may not include an article that is approved as a new drug. “Given that sildenafil was not marketed as a dietary supplement or as food before Viagra was approved, your “WeFun” product is excluded from the definition of dietary supplement…,” FDA says.

The letter says that in addition to being an unapproved drug, WeFun is misbranded because it does not contain adequate directions for use, because its labeling is false or misleading, and the labeling lacks adequate warnings for the protection of users.

In the letter, FDA also expressed concern about several other Hua Da products that may contain sildenafil or tadalafil, the active ingredient in Cialis.

The company was told to respond with a list of specific actions it has taken to address any violations and prevent their recurrence, with documentation of the actions.
