You've probably been given an antibiotic for a cold. So has almost everyone you know. You went to the doctor, described your symptoms, and left with a prescription. You took it. A few days later you felt better. And you thought: the antibiotic worked.

Here is something you were probably never told: you were going to feel better anyway. And there's a reasonable chance your doctor knew that when they handed you the prescription.

I want to give you a look behind the curtain.

This Is Not About Bad Doctors

Before I explain what's actually happening, I want to say something clearly: this is not an article about bad doctors. The vast majority of doctors I know went into medicine because they wanted to help people. They are not writing prescriptions to deceive you. They are operating inside a system that has spent decades making the prescription pad the path of least resistance — and understanding that system is the first step to navigating it differently.

How We Got Here

The story starts in the 1940s with penicillin. It was genuinely miraculous — infections that had killed people for centuries could suddenly be treated. The medical instinct was to use it broadly, including for respiratory illness. At the time, that wasn't unreasonable. The science of respiratory viruses was still being written. By the time medicine fully understood that viruses — not bacteria — cause the common cold, the habit of reaching for an antibiotic at the first sign of a sore throat or sinus pressure was already deeply embedded.

Alexander Fleming, who discovered penicillin, saw it coming. Accepting the Nobel Prize in 1945, he warned that overuse would teach bacteria to resist the drug before it could kill them. The warning went largely unheeded.

The habit outlasted the evidence. And then the system built itself around the habit.

The Billing System

In the decades that followed, American healthcare built a payment model based on complexity. The more complex a visit was documented, the higher the reimbursement. For a physician seeing a patient with a cold, this created a quiet but powerful incentive: document the discolored mucus, call it sinusitis, prescribe an antibiotic, bill a higher code.

This was not a conspiracy. For decades, bacterial respiratory illness was a real and significant problem, and antibiotics had a genuine role. Then vaccines changed the landscape dramatically. As those bacterial illnesses came under control, the window where antibiotics were truly needed narrowed sharply. The prescribing habits did not narrow with it. The pattern worked, and patterns that work get repeated. When a bacterial respiratory infection is actually present, antibiotics are still the correct treatment. That has never changed. What changed is how rarely that's actually the case for what brings people to urgent care with a cold.

The Liability Culture

American medicine was transformed by the rise of malpractice litigation. In that environment, the calculus of watchful waiting shifted dramatically. If a physician chose not to prescribe an antibiotic and the patient developed a complication — however unlikely — that physician faced potential liability. If a physician prescribed an antibiotic that wasn't needed and nothing bad happened, the legal risk was near zero.

This is not an excuse. It is a structural reality — built into the system long before your last visit, and long before your doctor's first one.

The Training Cascade

Medical training is an apprenticeship. Residents learn from attending physicians. Attending physicians learned from their attendings. And their attendings learned from the generation shaped by post-penicillin optimism, billing systems that rewarded complexity, and malpractice attorneys who made watchful waiting feel dangerous.

A resident who watches their attending prescribe azithromycin for every sore throat and amoxicillin for every patient with green mucus learns: this is what you do. When that resident becomes an attending — and prescribes those medications for thousands of patients who all get better, hear fewer complaints, and never lose sleep over possibly missing something — they develop a genuine clinical belief. Even if the science doesn't support it. The correlation becomes conviction. The reinforcement becomes habit.

This cascade has never been fully interrupted. It is still running today.

The Fifteen-Minute Visit

A typical urgent care visit is fifteen minutes. In that window, a history must be taken, an exam must be performed, the encounter must be documented, and your concerns must be addressed. Explaining why you — with a seven-day cold, discolored mucus, and sinus pressure — do not need an antibiotic, and having you leave satisfied, takes time most clinicians don't have and often don't have the tools to use effectively.

This platform exists, in part, to do the education that the fifteen-minute visit cannot. If you arrive at your appointment already understanding what a cold is, what the expected arc looks like, and why antibiotics don't change it — you've given your clinician something invaluable. You've made the conversation possible before it even starts.

The Satisfaction Score

The modern healthcare system has imported the customer service model. Patients now rate their physicians the way they rate restaurants and car dealers. Those ratings affect reimbursement and, in many systems, directly affect physician compensation and employment. A patient who doesn't receive the antibiotic they expected may leave a lower score. Physicians know this.

Nearly half of healthcare providers in one survey reported altering medical treatment based on the potential for a negative patient satisfaction score. The opioid epidemic followed the same logic — pain became a measurable patient satisfaction metric, and opioid prescribing rose. The antibiotic story is the same dynamic, playing out more quietly.

Here is the part worth sitting with: research has shown that prescribing unnecessary antibiotics does not actually improve patient satisfaction scores. The fear driving the behavior is, in many cases, not supported by the data. But fear is a powerful motivator — and it has been quietly driving this pattern for decades.

The Market

In a fragmented healthcare market — urgent care chains, telemedicine platforms, walk-in clinics — patients who don't receive the prescription they expect can simply go elsewhere. And they do. If one practice holds the line on responsible prescribing and another two miles away prescribes freely, patients vote with their feet. Revenue follows.

Telemedicine has amplified this. No continuity, no ongoing relationship, high volume, low barrier to switching. A physician who won't prescribe is one click away from being replaced by one who will — and I experienced that firsthand.

This is not a clinical problem. It is an economic one. And it has made antibiotic overprescribing structurally self-reinforcing in ways that no individual physician's good intentions can fix alone.

What You Can Do With This

Understanding the system your physician operates inside doesn't mean distrusting your physician. It means understanding that when you walk in expecting an antibiotic, you are carrying the weight of a decades-long conditioning process — and in many cases, so is your doctor.

That is patient agency in practice. It is also, not coincidentally, better care.

The education on this platform is designed to give you that understanding. Not to replace your physician. Not to make you distrust them. To make you a more informed patient — one who knows when to push back, when to ask questions, and when to say: is this antibiotic actually necessary?

When you understand what's happening in your body during a cold — and why antibiotics don't change it — you become part of the solution to one of the largest public health problems in modern medicine.
