01Registration, listing & premarketThe firm sold unapproved new drugs without FDA-approved applications, violating the FD&C Act.
No approved applications pursuant to section 505 of the FD&C Act are in effect for these products. Accordingly, their introduction or delivery for introduction into interstate commerce violates sections 301(d) [21 U.S.C. § 331(d)] and 505(a) of the FD&C Act.
02Labeling, claims & marketing · 21 CFR 201.5, 21 CFR 201.115(a)The firm sold prescription drugs without adequate directions for layperson use, causing misbranding.
Because the aforementioned drugs are prescription drugs intended for conditions that are not amenable to self-diagnosis and treatment by a layperson, adequate directions cannot be written such that a layperson can use the products safely for their intended uses. Consequently, the labeling for these drugs fails to bear adequate directions for their intended uses, causing them to be misbranded under section 502(f)(1) of the FD&C Act.

What FDA requested

  • Cease sale of unapproved and misbranded products
  • Email FDA describing steps taken to address violations
  • Provide explanation of each corrective step and documentation
  • State reason for delay if unable to complete corrections within 48 hours
  • Provide reasoning and supporting information if products believed compliant

1WARNING LETTER

6 paragraphs

DATE: July 20, 2021

RE: Notice of Unlawful Sale of Unapproved and Misbranded Drugs to United States Consumers Over the Internet

This is to advise you that the United States (U.S.) Food and Drug Administration (FDA) reviewed your website at the Internet address www.rxmedkart.com on May 12, 2021. FDA has observed that your website offers drug products for sale in the U.S. and that these products are intended to mitigate, prevent, treat, diagnose, or cure COVID-19 as well as strongyloidiasis, onchocerciasis, and lymphatic filariasis.1 Based on our review, these products are unapproved new drugs sold in violation of section 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) [21 U.S.C. § 355(a)]. Furthermore, these products are misbranded drugs under section 502 of the FD&C Act [21 U.S.C. § 352]. The introduction or delivery for introduction of these products into interstate commerce is prohibited under sections 301(a) and 301(d) of the FD&C Act [21 U.S.C. § 331(a) and 331(d)].

There is currently a global outbreak of respiratory disease caused by a novel coronavirus that has been named “severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2). The disease caused by the virus has been named “Coronavirus Disease 2019” (COVID-19). On January 31, 2020, the Department of Health and Human Services (HHS) issued a declaration of a public health emergency related to COVID-19 and mobilized the Operating Divisions of HHS.2 In addition, on March 13, 2020, the President declared a national emergency in response to COVID-19.3 Therefore, FDA is taking urgent measures to protect consumers from certain products that, without approval or authorization by FDA, claim to mitigate, prevent, treat, diagnose, or cure COVID-19 in people. As described below, FDA has observed that your website offers drug products for sale in the U.S. that are intended to mitigate, prevent, treat, diagnose, or cure COVID-19 in people.

There are inherent risks to consumers who purchase unapproved new drugs and misbranded drugs. Unapproved new drugs do not carry the same assurances of safety and effectiveness as those drugs subject to FDA oversight.

Drugs that have circumvented regulatory safeguards may be contaminated, counterfeit, contain varying amounts of active ingredients, or contain different ingredients altogether. We request that you cease the sale of any unapproved and misbranded products, whether for the mitigation, prevention, treatment, diagnosis, or cure of COVID-19, or any other disease for which the drugs you are selling are not approved by FDA for distribution in the U.S.

2Unapproved New Drugs:

2 paragraphs

As labeled, certain products offered for sale by www.rxmedkart.com are drugs within the meaning of section 201(g) of the FD&C Act [21 U.S.C. § 321(g)] because they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease and/or because they are intended to affect the structure or function of the body. These drugs are also new drugs as defined by section 201(p) of the FD&C Act [21 U.S.C. § 321(p)], because they are not generally recognized as safe and effective for their labeled uses. With certain exceptions not applicable here, new drugs may not be legally introduced or delivered for introduction into interstate commerce without prior approval from FDA, as described in section 505(a) of the FD&C Act [21 U.S.C. § 355(a)]. No approved applications pursuant to section 505 of the FD&C Act are in effect for these products. Accordingly, their introduction or delivery for introduction into interstate commerce violates sections 301(d) [21 U.S.C. § 331(d)] and 505(a) of the FD&C Act.

For example, www.rxmedkart.com offers zinc acetate, doxycycline, and ivermectin marketed as a “Ziverdo Kit.” Your website states, “Ziverdo Kit Contains Zinc Acetate 50 mg, Doxycycline 100 mg & Ivermectin 12 mg Dispersible Tablets. It is currently intimated in the first-line treatment for COVID-19 positive patients.” On the product page for the “Ziverdo Kit” offered on www.rxmedkart.com, you also state, “Quadruple Treatment with Ivermectin is powerful in handling COVID-19.” While there are FDA-approved versions of zinc acetate, doxycycline, and ivermectin on the market in the U.S., there are no approved drug applications pursuant to section 505 of the FD&C Act in effect for the “Ziverdo Kit” containing zinc acetate, doxycycline, and ivermectin offered by www.rxmedkart.com. FDA-approved zinc acetate is approved for the maintenance treatment of patients with Wilson’s disease who have been initially treated with a chelating agent, and is only available by prescription. FDA-approved doxycycline is approved for the treatment of a number of specific infections such as respiratory tract infections caused by Mycoplasma pneumoniae and Lymphogranuloma venereum caused by Chlamydia trachomatis, and is only available by prescription. FDA-approved ivermectin tablets are approved for the treatment of intestinal (i.e., nondisseminated) strongyloidiasis due to the nematode parasite Strongyloides stercoralis and onchocerciasis due to the nematode parasite Onchocerca volvulus, and are only available by prescription. In addition, zinc acetate, doxycycline, and ivermectin, alone or in combination with one another, have not been approved by FDA for use in the prevention, diagnosis, treatment, mitigation, or cure of COVID-19.

3Misbranded Drugs:

6 paragraphs

A drug is misbranded under section 502(f)(1) of the FD&C Act [21 U.S.C. § 352(f)(1)] if it fails to bear adequate directions for its intended use(s). “Adequate directions for use” means directions under which a layperson can use a drug safely and for the purposes for which it is intended (see 21 CFR 201.5). Prescription drugs, as defined in section 503(b)(1) of the FD&C Act [21 U.S.C. § 353(b)(1)] include those that, because of their toxicity or other potentiality for harmful effect, and/or the method of their use, and/or the collateral measures necessary for their use, are not safe for use except under supervision of a practitioner licensed by law to administer them. Prescription drugs, as defined in section 503(b)(1)(A) of the FD&C Act, can only be used safely at the direction, and under the supervision, of a licensed practitioner.

Because the aforementioned drugs are prescription drugs intended for conditions that are not amenable to self-diagnosis and treatment by a layperson, adequate directions cannot be written such that a layperson can use the products safely for their intended uses. Consequently, the labeling for these drugs fails to bear adequate directions for their intended uses, causing them to be misbranded under section 502(f)(1) of the FD&C Act. In addition, because these drugs are not approved in the U.S., they are also not exempt under 21 CFR 201.115(a) from the requirements of section 502(f)(1) of the FD&C Act. By offering these drugs for sale to U.S. consumers, www.rxmedkart.com is causing the introduction of misbranded drugs into interstate commerce in violation of section 301(a) of the FD&C Act [21 U.S.C. § 331(a)].

FDA is taking this action against www.rxmedkart.com because of the inherent risk to consumers who purchase misbranded and unapproved new drugs. This letter is not intended to identify all the ways in which your products or operations might be in violation of the law. It is your responsibility to ensure that all products you offer for sale are in compliance with the FD&C Act and its implementing regulations. You should take prompt action to address any violations of the FD&C Act (which may include the offer for sale of similarly misbranded and/or unapproved new drugs other than the drugs noted above). We advise you to review your websites, product labels, and other labeling and promotional materials to ensure that you are not misleadingly representing your products as safe and effective for a use for which they have not been approved by FDA and that you do not make claims that misbrand the products in violation of the FD&C Act.

Within 48 hours, please send an email to FDAInternetPharmacyTaskForce-CDER@fda.hhs.gov and COVID-19-Task-Force-CDER@fda.hhs.gov describing the specific steps you have taken to address any violations and to prevent their recurrence. Include an explanation of each step being taken to remedy and prevent the recurrence of any violations, as well as copies of related documentation. Failure to adequately address this matter may result in legal action, including, without limitation, seizure and injunction, without further notice. If you cannot complete corrective action within 48 hours, state the reason for the delay and the time within which you will complete the corrections. This letter notifies you of our concerns and provides you with an opportunity to address them. If you believe that your products are not in violation of the FD&C Act, include your reasoning and any supporting information for our consideration within 48 hours.

If you are not located in the U.S., please note that products that appear to be misbranded or unapproved new drugs may be detained or refused admission. We may advise the appropriate regulatory officials in the country from which you operate that your products referenced above appear to be unapproved and misbranded products that cannot be legally sold to consumers in the U.S.

Please direct any inquiries to FDA at FDAInternetPharmacyTaskForce-CDER@fda.hhs.gov and COVID-19-Task-Force-CDER@fda.hhs.gov.

Sincerely, /S/ Donald D. Ashley Director Office of Compliance Center for Drug Evaluation and Research Food and Drug Administration
