Medical Advertising and COFEPRIS in Mexico: What Doctors Can and Can't Say

COFEPRIS, the Comisión Federal para la Protección contra Riesgos Sanitarios (Federal Commission for Protection against Sanitary Risks), is the authority that oversees, among many other things, the advertising of health-related products and services in Mexico. Its rulebook is the Ley General de Salud (the General Health Law) and its Reglamento en Materia de Publicidad (the Advertising Regulations), which spell out what can be promoted, and under what conditions, whenever a message touches on people's health.

In practice, that covers almost everything a doctor or clinic publishes to attract patients: your website, your social media, the materials in your office, your signage, your brochures, and your paid ads. It isn't a single, universal permit; it's a set of content rules. What matters is what you say and how you say it, not just where you post it.

There's one operational distinction worth understanding. Much of the professional information you'll want to share (your name, specialty, services, location, hours) is handled through an aviso de publicidad, an advertising notice that's a simpler, lighter-touch filing designed for individual practitioners and clinics. Broader campaigns, or claims that require backing, tend to fall under a permiso de publicidad, an advertising permit. Knowing which bucket you're in saves you friction and defines what you're free to communicate.

Behind every rule sits a single idea worth internalizing, because it explains ninety percent of the cases: health advertising must not mislead, confuse, or create expectations that the patient has no way to evaluate on their own. A patient rarely has the technical knowledge to judge a clinical promise, so the law protects them by requiring messages that are truthful, verifiable, and free of exaggeration.

Adopt that principle as your filter and most decisions become intuitive. Before you publish anything, ask yourself: is it true, can I back it up, and does it honestly describe what I offer? If the answer is yes, you're almost always on solid ground. The regulation isn't there to silence you; it's there so you compete on the quality and clarity of what you communicate, not on who makes the boldest promise.

That same standard is also good business. Trust is a doctor's most valuable asset, and measured, verifiable messaging builds far more of it over the long run than spectacular claims ever will.

There's far more room here than most doctors assume. You can introduce yourself with your name and your training: your specialty, your professional license (cédula profesional), your education, your certifications, and your track record. Identity and credentials, as long as they're real and verifiable, are precisely the kind of content the law wants patients to be able to see.

You can also describe your services and areas of care in clear, factual terms; list your location, hours, and ways to reach you; and explain, in an educational way, what a procedure involves, what the care process looks like, or what a patient should expect. Informative and educational content (articles, answers to common questions, explanations of conditions) is wide-open territory and genuinely well regarded, because it informs without promising.

The thread running through all of it is tone: describe, don't exaggerate; inform, don't guarantee. Communicating your experience, your approach, and your bedside manner is fully compatible with the rules, and it's usually exactly what leads a patient to choose one doctor over another.

The tricky territory is predictable, and it almost always revolves around promises. Steer clear of guaranteeing results or cures, promising that a treatment is foolproof or one hundred percent effective, and using words like miraculous, one-of-a-kind, or definitive. It's also best to avoid attributing curative properties that aren't backed by science, and comparisons that suggest you're superior to other professionals without evidence to support it.

Just as sensitive is anything that can read as pressure or alarm: messages that overstate the risk of not being treated, that manufacture artificial urgency, or that play on a patient's fear. Beyond being squarely on the regulation's radar, these tactics erode the very trust a doctor needs to project.

The good news is that almost everything you should avoid has a permitted, more persuasive version. Instead of guaranteeing a result, describe the procedure and the care you provide alongside it. Instead of claiming you're the best, let your training and the way you explain things speak for you. The responsible message isn't the weak one.

Two formats raise more questions than any others, and for good reason, because they're the most sensitive. Patient testimonials and before-and-after images can create expectations of a specific result, which is exactly what the law is guarding against. Testimonials that claim someone was cured, or that implicitly promise the next patient will get the same outcome, are among the uses the regulation flags most often.

That doesn't mean they're off-limits in every case, but it does mean they demand real care: explicit consent from the patient, honest context making clear that results vary from person to person, and framing that fits the type of authorization your campaign requires. A before-and-after presented as proof of a guaranteed result is a problem; a well-contextualized, consented, educational piece is a different conversation entirely.

Our practical recommendation is to treat these formats as case-by-case decisions rather than a default tool. There are often alternatives that are just as powerful (walking through the process, showing your method, educating patients about the condition) and build trust without stepping into the most exposed zone.

At The Clinical Marketing, we start from one premise: complying and growing aren't in conflict. We design communication for doctors and clinics with patient protection at the center, so every message is truthful, clear, and verifiable, and at the same time sets your practice apart and draws in the right patients.

In practice, that means a concrete approach: we review what you can communicate given your situation and the type of authorization that applies, we build messages that spotlight your training, your method, and your bedside manner without leaning on promises, and we handle the sensitive formats with the care they deserve. The result is a professional presence that earns patients' trust and gives you peace of mind.

If you'd like to review your current communication or build a campaign from scratch with this approach, book a call with us.
