01Registration, listing & premarketUnapproved new drugs introduced into interstate commerce without FDA approval.
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)Misbranded drugs because labeling lacks adequate directions for use.
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 use. Consequently, the labeling for these drugs fails to bear adequate directions for use, causing them to be misbranded under section 502(f)(1) of the FD&C Act.
What FDA requested
- Cease offering any unapproved and misbranded drugs for sale to U.S. consumers.
- Review websites, product labels, and other labeling and promotional materials to ensure compliance.
- Notify FDA in writing within 15 working days describing specific steps taken to address violations and prevent recurrence.
- Include explanation of each step taken to remedy and prevent recurrence, with copies of related documentation.
- If corrective action cannot be completed within 15 working days, state reason for delay and time for completion.
- If believing products are not in violation, provide reasoning and supporting information within 15 working days.

FROM: The United States Food and Drug Administration
RE: Notice of Unlawful Sale of Unapproved and Misbranded Drugs to United States Consumers Over the Internet
DATE: September 30, 2024
2WARNING LETTER
3 paragraphs
This is to advise you that the United States (U.S.) Food and Drug Administration (FDA) has observed that Mexicanrxpharm.com introduces into interstate commerce misbranded and unapproved new drugs in violation of sections 301(a), 301(d), 503(b), and 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) [21 U.S.C. §§ 331(a), 331(d), 353(b), and 355(a)].
As discussed below, FDA has observed that Mexicanrxpharm.com introduces into interstate commerce unapproved and misbranded opioid drug products. Opioid addiction and abuse have created an immense public health crisis, and the death toll is staggering. Given the severity of the opioid epidemic, the easy availability of opioids via the Internet poses significant risks to U.S. consumers.
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. Accordingly, FDA requests that Mexicanrxpharm.com cease offering any unapproved and misbranded drugs for sale to U.S. consumers. This is critical to shielding the American public from harm.
3Unapproved New Drugs:
3 paragraphs
Certain products offered for sale by Mexicanrxpharm.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, Mexicanrxpharm.com offers tramadol marketed as “Adiolol Tramadol 100mg,” described as used for the “treatment of moderate to severe pain, both acute and chronic, as well as painful diagnostic or therapeutic procedures.” While there are FDA-approved versions of tramadol 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 “Adiolol Tramadol 100mg” offered by Mexicanrxpharm.com. FDA-approved tramadol is indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate and is only available pursuant to a prescription from a licensed practitioner. FDA-approved tramadol bears a boxed warning, commonly referred to as a “black box warning,” which is the strongest warning FDA requires, indicating that the drug carries a significant risk of serious or even life-threatening adverse effects. The boxed warning addresses risks including addiction, abuse, misuse, life-threatening respiratory depression (breathing problems), and neonatal opioid withdrawal syndrome (withdrawal symptoms in newborn baby). In addition, when taken in conjunction with other central nervous system depressants, including alcohol and benzodiazepines, use may result in coma or death.
Mexicanrxpharm.com also offers a tramadol product marketed as “Tramacet Tramadol, Paracetamol 37.5 mg/325mg.” Mexicanrxpharm.com describes “Tramacet Tramadol, Paracetamol 37.5 mg/325mg” as “somatic treatment of severe pain syndrome.” There are no approved drug applications pursuant to section 505 of the FD&C Act in effect for the “Tramacet Tramadol, Paracetamol 37.5 mg/325mg” offered by Mexicanrxpharm.com.
4Misbranded 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 its labeling fails to bear adequate directions for use. “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 be used safely only 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 use. Consequently, the labeling for these drugs fails to bear adequate directions for use, causing them to be misbranded under section 502(f)(1) of the FD&C Act. In addition, because the 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, Mexicanrxpharm.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 sending this warning letter to Mexicanrxpharm.com because of the inherent risks 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 are not distributing misbranded products in violation of the FD&C Act.
Please notify this office in writing within 15 working days 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 15 working days, 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 15 working days.
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 your response and any inquiries to FDA at FDAInternetPharmacyTaskForce-CDER@fda.hhs.gov.
