Prescriptions Without Purpose: The Growing Crisis of Unnecessary Medications in American Healthcare

Somewhere in America right now, a patient is leaving a doctor's office with a prescription they didn't necessarily need. Perhaps their visit lasted eight minutes. Perhaps they mentioned feeling anxious and left with a benzodiazepine. Perhaps they asked about a medication they saw advertised during a prime-time television commercial, and their physician, pressed for time and reluctant to disappoint, wrote the script.

This is not a fringe scenario. According to the Centers for Disease Control and Prevention, approximately 131 million Americans — roughly 66 percent of all adults — use at least one prescription drug. Studies published in peer-reviewed journals have consistently found that a meaningful percentage of those prescriptions may be unnecessary, duplicative, or prescribed at doses higher than required. The financial and physical costs of this pattern are staggering.

What Overprescribing Actually Means

Overprescribing is not a single, clearly defined phenomenon — it is a spectrum of prescribing behaviors that result in patients receiving medications that offer little or no benefit given their specific clinical circumstances, or that carry risks outweighing their potential advantages.

The pattern takes several forms:

• Prescribing when watchful waiting would suffice. Antibiotics for viral infections are the most cited example. The CDC estimates that roughly 28 percent of antibiotic prescriptions written in outpatient settings are unnecessary — a practice that costs patients money and contributes to the national crisis of antibiotic resistance.
• Prescribing at higher doses than necessary. Pain management is a particularly sensitive area, where the pressure to address patient discomfort quickly can sometimes result in opioid prescriptions that exceed clinical need.
• Prescribing without revisiting the original justification. Medications prescribed for a short-term condition often remain on a patient's medication list indefinitely, simply because no one paused to ask whether they were still needed.
• Prescribing in response to patient demand. Research consistently shows that patients who request a specific medication are more likely to receive it — even when clinical evidence for that medication is weak.

The Role of Pharmaceutical Marketing

The United States is one of only two countries in the world — the other being New Zealand — that permits direct-to-consumer (DTC) pharmaceutical advertising. The American pharmaceutical industry spends billions of dollars each year on television commercials, digital advertising, and print campaigns encouraging consumers to "ask their doctor" about specific branded medications.

This practice has measurable effects on prescribing behavior. A 2016 study published in the Journal of General Internal Medicine found that physician visits in which patients mentioned seeing a DTC advertisement were significantly more likely to result in a prescription — even when the prescribing physician had reservations about the medication's necessity.

Beyond consumer-facing advertising, pharmaceutical companies have historically invested heavily in physician outreach — including continuing medical education programs, sponsored conferences, and, until more stringent regulations were enacted, direct gifts to prescribers. While the Physician Payments Sunshine Act, enacted under the Affordable Care Act, now requires public disclosure of financial relationships between drug manufacturers and healthcare providers, critics argue that the influence of pharmaceutical marketing on prescribing culture has not been fully dismantled.

Defensive Medicine and the Liability Factor

American physicians practice in a uniquely litigious environment. Fear of malpractice claims can drive prescribing decisions in ways that have little to do with clinical evidence. A physician who prescribes a medication — even one of marginal benefit — may feel more legally protected than one who recommends lifestyle modification and monitoring.

This phenomenon, often called defensive medicine, extends beyond prescribing to encompass unnecessary diagnostic testing, specialist referrals, and hospitalizations. But in the context of medications, it means that patients may receive prescriptions not primarily because their doctor believes those drugs are the best course of action, but because prescribing them reduces the physician's perceived legal exposure.

Healthcare economists have long argued that meaningful tort reform — combined with stronger clinical decision-support tools — could reduce defensive prescribing. In the meantime, patients bear both the cost and the risk.

What Overprescribing Costs the American Patient

The financial burden is not abstract. A 2019 report from the National Academy for State Health Policy estimated that Americans waste billions of dollars annually on unused or unnecessary prescriptions. Many patients fill a prescription, experience side effects, and abandon the medication — yet the cost has already been incurred.

For patients on fixed incomes, particularly seniors enrolled in Medicare Part D, the financial pressure is acute. Paying a copay for a medication that was never truly needed — or that could have been replaced by a lower-cost alternative — compounds the already significant economic stress of managing chronic illness in the United States.

Beyond direct costs, unnecessary medications expose patients to adverse drug events. Every medication carries risk. Polypharmacy — the concurrent use of multiple medications — increases the likelihood of drug-drug interactions, falls, cognitive impairment, and hospitalizations. Research published in the Journal of the American Geriatrics Society has found that a significant proportion of hospital admissions among older adults are attributable to adverse drug events, many of which were preventable.

Patient Stories: When More Wasn't Better

Consider the experience of a 58-year-old woman in Ohio who was prescribed a proton pump inhibitor (PPI) following a bout of acid reflux after a stressful period at work. Two years later, she was still filling the prescription monthly — despite her reflux having resolved — because no follow-up appointment had addressed whether the medication was still necessary. PPIs, while effective for short-term use, are associated with increased risk of kidney disease, bone fractures, and Clostridioides difficile infections with long-term use.

Or consider a 34-year-old man in Georgia who visited an urgent care clinic with upper respiratory symptoms and left with both an antibiotic and a prescription-strength cough suppressant. His illness was viral. Neither medication was likely to shorten his recovery — but both carried side effects and combined costs exceeding $80 after insurance.

These are not exceptional cases. They are representative of patterns that researchers and clinicians have documented across the country.

How to Have an Honest Conversation With Your Doctor

Advocating for yourself within the healthcare system is not always comfortable, but it is both your right and your responsibility as a patient. The following questions can help you determine whether a new prescription is genuinely necessary:

1. "What is this medication treating, specifically?" Ensure you understand the precise condition or symptom being addressed.
2. "What happens if I don't take this medication?" For some conditions, watchful waiting or lifestyle modifications may be equally appropriate first-line approaches.
3. "Are there non-drug alternatives I should try first?" Physical therapy, dietary changes, and behavioral interventions are clinically validated for numerous conditions.
4. "How long will I need to take this?" Establish a clear timeline and a plan for reassessment.
5. "What are the most common side effects, and when should I call your office?" Understanding the risk profile helps you make an informed decision.
6. "Is there a generic or lower-cost equivalent?" If a prescription is genuinely necessary, there is no reason to pay more than required.

You are also entitled to a second opinion. If a diagnosis or treatment recommendation doesn't feel right, consulting another physician is a legitimate and often valuable step.

Deprescribing: A Growing Movement in American Medicine

The medical community is increasingly recognizing that removing unnecessary medications from a patient's regimen — a practice known as deprescribing — is a legitimate and often beneficial clinical intervention. Several academic medical centers and pharmacy schools across the country now have dedicated deprescribing programs, and resources such as Deprescribing.org offer evidence-based guidelines for patients and clinicians alike.

If you believe you are taking medications that may no longer be necessary, raising this directly with your physician or pharmacist is entirely appropriate. A comprehensive medication review — sometimes called a brown bag review, in which you bring all your current medications to an appointment — can be an effective starting point.

The Path Forward

Overprescribing is a systemic problem with systemic causes. Addressing it fully will require changes to physician incentive structures, pharmaceutical marketing regulations, malpractice liability frameworks, and the time constraints that define most clinical encounters in American medicine today.

But individual patients are not powerless. Asking informed questions, requesting medication reviews, and approaching each new prescription with a degree of healthy scrutiny are meaningful acts of self-advocacy. At MedGuide USA, we believe that an informed patient is the most effective check on unnecessary prescribing — and that the conversation between you and your doctor is the first place meaningful change can begin.
