You order a dietary supplement from a website that looks like a pharmacy, the package arrives in an anonymous blister, without a notice in French, and with an expiration date that is hard to read. This kind of situation is becoming more common, and it raises a very concrete question: how can you verify that an online pharmacy deserves your trust before finalizing your cart?
Returns, refunds, and defective products: what the law requires from online pharmacies
When you receive a bottle of syrup that is cracked or a product whose expiration date has passed, the first reaction is to look for a return form. On an authorized online pharmacy, the right of withdrawal of 14 days applies to unopened parapharmacy products. For medications, the situation is different: once shipped, they cannot be returned or put back into circulation for obvious health reasons.

A defective or expired product upon receipt falls under the legal warranty of conformity. The licensed pharmacist, responsible for the site, must proceed with the replacement or refund. This point can be verified in the general terms and conditions of sale, and it is a reliable indicator of the site’s seriousness.
Prescription medications are not subject to online sales in France. Any French online pharmacy offering medications requiring a prescription operates outside the legal framework. This is an immediate warning signal.

On Pharmavia, the return conditions and contact details of the responsible pharmacist are accessible even before placing an order, allowing for verification of these guarantees in advance.
ARS authorization number and European logo: the checks that really matter
Since January 2026, a decree published in the Official Journal (JORF n°0294 of December 18, 2025) requires French online pharmacies to display a visible and clickable ARS authorization number, leading directly to the official directory. This obligation aims to counter fraudulent sites that merely copied official logos without any verifiable link.
In practice, we check two elements before placing any order:
- The common European logo, present on every page of the site, which should link to the official list of authorized pharmacies maintained by the National Order of Pharmacists
- The ARS authorization number, now clickable, which directly opens the pharmacy’s profile on the website of the relevant regional health agency
- The complete legal mentions: name of the licensed pharmacist, address of the associated physical pharmacy, pharmacist’s RPPS number
If any of these elements are missing or not functioning, we move on. A site that displays a logo without an active link does not comply with current regulations.
Counterfeit dietary supplements on marketplaces: an underestimated risk
French pharmacists report an increase in cases of patients poisoned by counterfeit dietary supplements purchased on marketplaces like Amazon or AliExpress. Reported symptoms can be severe and are only detected after consumption, when the product has already caused harm.
A marketplace is not a pharmacy, even when it sells health products. The absence of a pharmacist in the distribution chain means that no healthcare professional is overseeing the product’s compliance, storage, or traceability.
On an authorized online pharmacy, each batch of products follows the same circuit as that of a physical pharmacy. The licensed pharmacist takes responsibility for the quality and compliance of each item offered. This difference may seem abstract when comparing prices, but it becomes very concrete when a product causes an adverse reaction.
What distinguishes an online pharmacy from a simple reseller
The online pharmacist is required to ask questions about your health status before validating certain orders. A health questionnaire before the sale of over-the-counter medications is part of the obligations. A site that sends paracetamol or ibuprofen without any prior questions does not fulfill its professional obligations.
Returns vary on this point: some sites integrate the questionnaire directly into the purchase process, while others send it via email after the order. Both approaches exist, but the complete absence of a questionnaire remains a negative signal.
Low prices and permanent promotions: when the price should raise alarms
A price significantly lower than that of a physical pharmacy for the same over-the-counter medication deserves verification. Authorized online pharmacies offer competitive prices due to lower structural costs, but a price gap that is too large may indicate a counterfeit or poorly stored product.
You can compare a given product across two or three authorized online pharmacies to get an idea of the normal price range. A site that consistently offers prices well below this range, combined with permanent promotions on medications, should raise caution.
Delivery and storage of medications
Some health products require a cold chain or specific storage conditions. A serious online pharmacy specifies the storage and shipping conditions for temperature-sensitive products. If no mention is made regarding the transport conditions of a product that should be kept cool, it is a gap that speaks volumes about the site’s practices.
The delivery time also matters: a medication that spends several weeks in an uncontrolled warehouse loses reliability. Online pharmacies linked to a physical pharmacy generally ship from their own stock, which shortens the logistics chain and limits the risks of degradation.
Choosing your online pharmacy is akin to applying the same reflex as in the city: you check that the pharmacist exists, that they are reachable, and that their activity is regulated by health authorities. The clickable ARS authorization number, explicit return conditions, and the presence of a health questionnaire are three quick checkpoints that eliminate the majority of dubious sites.
