Diabetes is one of the fastest-growing chronic diseases in the world, and its prevalence is increasing every year. In the United States, more than 38 million people have diabetes, and nearly one-quarter of adults are unaware of their condition. Additionally, around 96 million people have prediabetes, a condition that can be prevented from progressing through lifestyle changes, proper diet, and exercise.
With these rising numbers, the market for unauthorized and counterfeit diabetes products, marketed as “dietary supplements” or “over-the-counter medications,” has expanded. These products are not only ineffective but can also endanger patients’ health and cause serious complications.

1.Why Are Unauthorized Diabetes Medications Dangerous?
Products sold without official approval that claim to treat or prevent diabetes often contain unauthorized substances or even hidden prescription drugs. Using these products can lead patients to discontinue effective treatments, putting them at risk of severe complications.
Even seemingly harmless natural products can have negative effects, as their active ingredients are often unknown and may interact with other medications. No dietary supplement in Europe has been approved to treat or prevent diabetes.

The U.S. Food and Drug Administration (FDA) advises consumers not to use such products because:
- They may contain harmful substances or lack active ingredients.
- They are sometimes marketed as over-the-counter drugs or dietary supplements while hiding prescription medications.
- Using these products can delay or interrupt effective diabetes treatments, leading to serious complications.
2. Diabetes Complications and the Importance of Proper Treatment
People with diabetes face serious and sometimes irreversible health risks. Poor blood sugar control can damage various organs and systems in the body. Major complications of diabetes include:
- Cardiovascular disease: Diabetes increases the risk of heart attacks, strokes, and atherosclerosis.
- Chronic kidney disease (nephropathy): High blood sugar gradually impairs kidney function, potentially leading to kidney failure.
- Nerve damage (neuropathy): Elevated blood sugar can damage nerves, causing pain, numbness, or weakness in limbs.
- Foot problems: Neuropathy and poor circulation can result in non-healing wounds and even the risk of amputation.
- Oral health issues: Diabetic patients are more prone to gum disease, cavities, and oral infections.
- Hearing and vision loss: Diabetes can cause retinopathy and hearing impairment.
- Mental health issues: Anxiety, depression, and mood disorders are more common in diabetic patients, making disease management more challenging.
Using unauthorized or counterfeit products not only fails to control diabetes but also greatly increases the risk of these complications. Many of these products contain unknown ingredients or hidden prescription drugs that may interact with other medications and disrupt proper treatment.
Regular blood sugar monitoring, a healthy diet, exercise, and approved medications are the keys to reducing risks and maintaining long-term health for diabetic patients.

3. How Are Unauthorized Diabetes Medications Identified?
Signs of Fake Medications:
- Marketed as dietary supplements or over-the-counter medications
- Promises of guaranteed diabetes treatment or prevention
- Lack of transparent information about ingredients
Risks of Hidden Ingredients:
Some products claiming to be “natural” may contain prescription drugs. These illegal substances can interact with other medications and cause dangerously low blood sugar (hypoglycemia).
4. Online Fake Medications and Fake Pharmacies
The internet is a common marketplace for unauthorized drugs. Fake websites may:
- Sell counterfeit or unauthorized medications
- Provide prescription drugs without a prescription
- Fail to provide safe usage instructions
These products can be especially dangerous for sensitive medications such as insulin.

5. How to Identify Legitimate Online Pharmacies
- Require a valid prescription
- Provide a physical address in the U.S. or Europe
- Licensed by a state pharmacy board
- Offer access to a licensed pharmacist for consultation
For more information, visit BeSafeRx and FDA’s “Locate a State-Licensed Online Pharmacy.”
Guide to Safe Medication Purchase in Europe:
- Buy only from officially licensed pharmacies.
- Obtain a prescription from your doctor.
- Ensure a licensed pharmacist is available to answer questions.
- Look for the EU Common Logo, which links to the official European database.
Following these guidelines can reduce the risk of encountering counterfeit medications.
6.Reporting Problems and Adverse Reactions
Consumers and healthcare professionals can report issues with unauthorized medications through the FDA MedWatch program:
- Website: www.fda.gov/Medwatch/report.htm
- Phone: 800-FDA-1088
- Fax: 800-FDA-0178 (FDA Form 3500)
- In Germany: via BfArM – Pharmacovigilance Portal
- In Europe: via EMA or DG SANTE
The FDA also provides information and training for identifying counterfeit products.

Conclusion
Unauthorized diabetes medications pose a serious threat to patients’ health and can increase the risk of dangerous complications such as severe hypoglycemia, drug interactions, and cardiovascular or kidney diseases. These products not only lack scientific efficacy but also mislead patients with false promises, preventing access to effective treatment.
To properly manage diabetes and reduce the risk of complications:
- Use FDA- and EMA-approved medications: only authorized drugs guarantee effectiveness and safety.
- Monitor blood sugar regularly: continuous control is key to preventing serious complications.
- Follow a healthy diet and exercise routine: a healthy lifestyle plays a major role in slowing disease progression.
- Avoid buying unauthorized or online medications: counterfeit products can endanger your life.
By following these principles, patients can not only control their diabetes but also prevent severe and irreversible complications. Remember, your health is your most valuable asset, and informed choices are the best way to protect it.
Frequently Asked Questions:
- How can I ensure that my diabetes medication is legal and safe?
Only use medicines you can verify. Do the checks below—skip any source that fails one of them.
• Buy from licensed channels only: a brick-and-mortar pharmacy or an authorized online pharmacy listed by your national authority.
• Packaging integrity: unopened, tamper-evident seal intact, no spelling errors, no stickers covering the original label.
• Exact product match: brand name, strength, dosage form, and manufacturer exactly match your prescription.
• Batch & expiry: clear LOT/Batch number and expiry date printed (not just on a sticker). Dates must be consistent across box, blister, and leaflet.
• Safety features (where applicable): 2D barcode/unique identifier scans correctly and the pack has a tamper-evident device (per EU FMD or your country’s system). - What should I do if I have used an unauthorized medication?
Act immediately, waiting increases risk.
1. Stop using it now.
2. Contact your clinician or pharmacist for medical advice and monitoring.
3. Report it to your national medicines authority or pharmacovigilance portal (e.g., FDA MedWatch, EMA/BfArM, MHRA Yellow Card—use the one in your country).
4. Keep the pack (box, vial, blister) and your receipt. Do not throw them away; they’re needed for investigation.
5. Record details: where purchased, date, seller contact, batch/LOT, photos of the pack.
6. Replace only from an authorized source after professional confirmation.In April 2025, the U.S. FDA announced that several counterfeit units of Ozempic® (semaglutide) had been found in the U.S. drug supply. The counterfeit packs were labeled with lot PAR0362 and serial numbers beginning with 51746517.
