Fake and substandard medicines: how to stay safe when buying from abroad

The short answer
Substandard and falsified medicines are a real risk, especially online. WHO estimates that at least 1 in 10 medicines in low- and middle-income countries are substandard or falsified, and that they are often sold online or in informal markets. Buy only through licensed, traceable channels, never without a prescription, and be suspicious of prices that look too good.

- Our rule: US-licensed wholesale supply with a traceable chain.
Substandard versus falsified
WHO describes substandard products as those that do not meet quality standards and specifications, often because of poor manufacturing or quality control. Falsified products deliberately misrepresent their identity, composition or source, usually to deceive for profit.[1]
Both can fail to treat the illness, because the ingredients or doses are wrong, and both can directly harm patients if they contain contaminants or toxic substances. WHO also links them to antimicrobial resistance.[1]
How big the problem is
They affect all types of products, including vaccines, antibiotics and cancer therapies, and are found in every country.[1]
WHO says the rise of online sales through unauthorized sites has made it easier for falsified products to reach consumers, and that people buying from unauthorized sources, including online, are among those most at risk.[1]
Warning signs when buying from abroad
- The seller does not ask for a prescription for a prescription-only medicine.
- The price is far below what the medicine normally costs, or the seller offers bulk discounts on specialty medicines.
- The seller cannot say where the product came from or give a batch number and expiry date before shipping.
- There is no physical address, licence number or named pharmacist.
- Packaging or labels are in an unexpected language, or the product looks different from the official images.
FDA's checklist for US online pharmacies
FDA advises that a legitimate US online pharmacy requires a valid prescription, is licensed by the state board of pharmacy where it operates, has a physical US address and a licensed pharmacist available to answer questions. Its BeSafeRx campaign helps consumers spot unsafe sites.[2, 3]
How a traceable supply chain protects you
In the US, the Drug Supply Chain Security Act sets up an electronic, interoperable way to identify and trace certain prescription drugs at the package level through the supply chain, to keep harmful drugs out and remove them quickly if they get in.[4]
When a medicine is supplied for a named patient abroad, ask for the supplier's licence details, the product's batch and expiry, and the shipping record. A legitimate supplier will provide them without hesitation.
If you think a medicine is fake
- Do not use it. Keep the pack, the leaflet and any receipt or message from the seller.
- Tell the treating doctor and the hospital pharmacy, and ask them to report it to the national regulator.
- In the US, FDA's MedWatch program accepts reports about FDA-regulated products from consumers and health professionals.[5]
- Check whether the regulator in your country has issued a public alert about that product or batch.
Who is most at risk
WHO lists people buying from unauthorized sources, including online, countries with disrupted supply chains, and places with increased demand for specific products among those most at risk of substandard and falsified products.[1]
How Reserve Meds helps
Reserve Meds is a digital health company. Medicines are supplied through a US-licensed pharmaceutical wholesale partner. We help families and treating doctors understand the route, prepare the documents the regulator or hospital asks for, arrange supply from the US once approval is in place, and keep everyone updated. We do not diagnose, prescribe or decide what a regulator approves.
We coordinate access to FDA-approved medicines only. Investigational medicines are only available through a manufacturer's expanded-access program requested by the treating physician; we can explain that route, but we do not supply them. Your coordination fee is quoted in writing for your case before you commit. No hidden charges. We give you a written timeline estimate for your case before you commit.
