AddressedDear Mr. Shans

1Introduction

2 paragraphs

This letter is to advise you that the United States Food and Drug Administration (FDA) reviewed your website at the Internet address www.alfia.com, in December 2022, where you took orders for “Alfia Weight Loss Capsules.”1 In addition, FDA has obtained a sample and labeling of your “Alfia Weight Loss Capsules” product. As described below, this product is an unapproved new drug sold in violation of sections 505(a) and 301(d) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 355(a) and 331(d). Furthermore, your “Alfia Weight Loss Capsules” product is a misbranded drug under section 502 of the FD&C Act, 21 U.S.C. 352 and sold in violation of section 301(a) of the FD&C Act, 21 U.S.C. 331(a).

FDA confirmed through laboratory analysis that a sample of your “Alfia Weight Loss Capsules” contains undeclared sibutramine. Sibutramine is the active pharmaceutical ingredient in Meridia, a new drug approved by FDA for marketing in 1997 for prescription treatment of obesity and, subsequently, withdrawn from the United States market on December 21, 2010 after clinical data indicated sibutramine poses an increased risk of heart attack and stroke.

2Unapproved New Drug

12 paragraphs

Your “Alfia Weight Loss Capsules” product is a drug as defined by section 201(g)(1) of the FD&C Act, 21 U.S.C. 321(g)(1) because it is intended to diagnose, cure, mitigate, treat, or prevent disease and/or affect the structure or function of the body. Examples of claims observed on your website and product label that establish the intended use of your product as a drug include, but may not limited to, the following:

On your webpage, https://alfia.com/capsules/alfia-capsules-special-offer:

Under the heading, “How ALFIA Capsules works”:

“Curb your appetite, increase your energy and help your body to burn FAT. Removes deposited fat”

Under the heading, “Mechanism of Action”:

“ALFIA helps to digest the food, hasten ALFIA helps to digest the food, hasten the fat metabolism and protect the digest[sic] organs against diseases in advance.”

Under the heading, “Loosening bowel to relieve constipation decontaminating circulation system, promoting metabolism”:

“The ingredients which include semen cassia seed can loosen [the] bowel to relieve constipation. Therefore ALFIA can effectively excrete the metabolism outcome from the body, the redundant fat which cannot be absorbed and toxin so that the bowel system can be loosened and constipation can be prevented and cured.”

On the label of your “Alfia Weight Loss Capsules” product:

“Alfia 100% NATURAL WEIGHT LOSS CAPSULES”

“LOSE 27 POUNDS in 30 DAYS”

Your “Alfia Weight Loss Capsules” is not generally recognized as safe and effective for its above referenced uses and, therefore, is a “new drug” under section 201(p) of the FD&C Act, 21 U.S.C. 321(p). With certain exceptions not applicable here, a new drug may not be legally introduced or delivered for introduction into interstate commerce without prior approval from the FDA, as described in sections 301(d) and 505(a) of the FD&C Act, 21 U.S.C. 331(d) and 355(a). There is no FDA-approved application in effect for “Alfia Weight Loss Capsules.” Introduction or delivery of this product into interstate commerce violates sections 505(a) and 301(d) of the FD&C Act, 21 U.S.C. 355(a) and 331(d).

3Misbranded Drug

5 paragraphs

Your “Alfia Weight Loss Capsules” product is misbranded under section 502(f)(1) of the FD&C Act, 21 U.S.C. 352(f)(1), in that its labeling fails to bear adequate directions for use. “Adequate directions for use” mean directions under which a layman can use a drug safely and for the purposes for which it is intended, 21 CFR 201.5. It is impossible to write “adequate directions for use” for “Alfia Weight Loss Capsules” for at least two reasons: 1) prior to withdrawal of Meridia’s approval, FDA approval of sibutramine was limited to use under the professional supervision of a practitioner licensed by law to administer such drugs and 2) FDA approval of Meridia was withdrawn because of serious safety risks. As such, the labeling of “Alfia Weight Loss Capsules” fails to bear adequate directions for its intended uses, causing it to be misbranded under section 502(f)(1) of the FD&C Act. Your “Alfia Weight Loss Capsules” product is not exempt from the requirements that they bear adequate directions for use by a layperson, 21 CFR 201.100(c)(2) and 201.115, because no FDA-approved application is in effect for this product.

Additionally, under section 502(a) of the FD&C Act, 21 U.S.C. 352(a), a drug is misbranded if its labeling is false or misleading in any particular. Section 201(n) of the FD&C Act, 21 U.S.C. 321(n), provides that, in determining whether an article’s labeling or advertising “is misleading there shall be taken into account . . . not only representations made or suggested . . . but also the extent to which the labeling or advertising fails to reveal facts material in light of such representations . . ..” Your “Alfia Weight Loss Capsules” product is misbranded under section 502(a) of the FD&C Act because the labeling fails to reveal the sibutramine content, which is a material fact with respect to consequences that may result from the use of this product. As described above, sibutramine may pose health risks to consumers which are only compounded by the fact that the ingredient is not declared on the label.

“Alfia Weight Loss Capsules” is also misbranded under section 502(f)(2) of the FD&C Act, 21 U.S.C. 352(f)(2), because the product’s labeling lacks adequate warnings for the protection of users. As previously noted, there is potential for adverse events associated with the use of this product, particularly since someone who takes it would be unaware of the presence of the undeclared ingredients.

Likewise, “Alfia Weight Loss Capsules” is misbranded under section 502(j) of the FD&C Act, 21 U.S.C. 352(j), because it is dangerous to health when used in the dosage or manner recommended in the labeling. As previously noted, sibutramine poses an increased risk of heart attack and stroke.

The introduction or delivery for introduction into interstate commerce of this misbranded drug product is prohibited under section 301(a) of the FD&C Act, 21 U.S.C. 331(a).
