Survey Finds 45% of Americans Misread Drug Labels

Medication labels are important safety tools, but they are often skimmed, misunderstood or ignored altogether. Our survey of 600 U.S. adults found that many Americans make medication decisions based on habit, symptom relief or personal judgment rather than strictly following label instructions. The findings reveal how common everyday behaviors can increase the risk of dosing mistakes, drug interactions and avoidable health complications. 

Modern drug labels exist not just to guide patients, but also because manufacturers are legally required to disclose known risks, side effects and usage instructions. Many labeling rules were strengthened after public health crises and lawsuits revealed the dangers of inadequate warnings, unclear dosing information and undisclosed drug risks.

We asked respondents how often they carefully read drug labels before taking a medication, and most reported positive habits. Forty-five percent said they always read medication labels thoroughly, while another 40% said they do so some of the time. Only 11% admitted they rarely read drug labels, and 3.7% said they never read them.

At first glance, the results suggest that many Americans follow responsible medication practices. However, a closer look at the survey responses reveals a clear gap between perceived and actual behavior. While respondents often expressed confidence in how they use medications, that confidence does not always translate into safe, accurate or appropriate use in real-world situations.

Confidence vs. Comprehension Gap

There can be a wide gap between perceiving that you understand a drug label and truly understanding it. Medication labels are often dense, combining dosing instructions, active ingredients and critical safety warnings in small print that is easy to skim or misinterpret. This can lead to common mistakes such as taking doses too close together, assuming that more medication will work better or missing important interaction warnings like avoiding alcohol. The survey results highlight how frequently this gap between confidence and understanding appears in real-world medication use.

The findings become more complex when comparing what respondents say they do with how they behave in practice. While 94% of respondents reported reading and following dosing instructions for over-the-counter medications, a small share (6%) said they do not. Despite this high level of confidence in adherence, the data suggest that real-world use does not always align with stated behavior.

Taken together, the responses point to a broader disconnect between perceived adherence and how medications are actually used outside of clinical guidance. Factors such as symptom urgency, delayed relief and misinterpretation of dosing instructions may all contribute to deviations from label directions.

That gap becomes more visible when respondents are asked about specific behavior. Nearly half reported that they have taken a medication more frequently than the label directs, such as shortening the recommended four to six-hour intervals between doses of common pain relievers.

With 46.17% answering yes and 53.83% saying no, the findings underscore a consistent pattern: Even among respondents who believe they follow medication instructions, a significant share report behaviors that deviate from label guidance at least occasionally.

Common Dosing Errors

These behaviors highlight how easily medication instructions can be misinterpreted or adjusted in real-world settings, particularly when managing symptoms without clinical supervision.

While prescriptions are designed to guide patients through a full course of treatment, real-world behavior often reflects a more complex decision-making process. These decisions highlight how medication adherence is influenced not only by clinical instructions, but also by personal judgment, perception of risk and how people interpret information on drug labels.

Stopping Medication Before Completing a Prescribed Course

Survey results show that 44% of respondents reported stopping a prescribed medication before completing the full course, while 56% reported not doing so. These decisions are often not deliberate misuse but instead reflect situations in which symptoms improve sooner than expected, concerns about side effects arise, or instructions are not fully understood.

How Safety Concerns Influence Whether Treatment Begins

Beyond adherence, medication decisions also begin before the first dose is taken. For many people, concerns about potential side effects or warnings are strong enough to prevent them from starting a prescribed medication altogether.

In this case, 61.17% of respondents said they have avoided taking a medication due to side effect concerns, while 38.83% said they have not. This suggests that perceived risk plays a significant role not only in whether medications are continued, but also in whether they are taken at all. According to a study published in the Journal of General Internal Medicine, 18% of adults taking prescription medications reported experiencing a drug complication or side effect.

Interpreting the Disconnect Between Intent and Behavior

Taken together, these findings show that medication decisions are influenced at multiple points in the treatment process. While caution around side effects can be appropriate in some cases, it can also lead to interruptions or avoidance of treatment that may carry their own health risks.

Survey respondents described stopping medications early in ways that reflect this tension. One noted, “Antibiotic. I felt better before my script ran out.” Another said, “It was just too much, and it was making me feel off.”

Each year, more than 1.5 million emergency room visits in the United States are linked to adverse drug events. Incorrect or incomplete use of medications can also increase the risk of toxicity, particularly with drugs like acetaminophen, where the margin between safe and harmful dosing is narrow. In chronic conditions, missed doses may contribute to complications such as nerve or eye damage from poorly controlled diabetes or allow infections to progress when antibiotics are not completed.

Around half of survey respondents (49%) believe over-the-counter (OTC) medications carry fewer risks than prescription drugs. This perception is understandable, given that OTC medications are widely available without a prescription and marketed for everyday use, but it can also create a false sense of safety that underestimates the potential risks of misuse, interactions and side effects.

Hidden Risks of OTC Medications

While most OTC medications are safe to use, they can still interact with each other or cause side effects. For those with chronic conditions like kidney disease, OTC medications may not be appropriate. Medications like NSAIDs, including ibuprofen, carry a high risk of injury for those with chronic kidney disease.

When patients receive a new prescription, they are often given a pharmacy information sheet outlining key details about the medication, including usage instructions, potential side effects and safety warnings. These documents are designed to reinforce what is discussed during the prescription process and provide an additional layer of safety information.

Survey results show that 78.83% of respondents said they read or review the pharmacy information sheet that they receive with their medication, while 21.17% said they do not. This suggests that while most patients engage with written medication guidance, a meaningful portion may be missing an additional source of safety information beyond the prescription label.

In practice, these information sheets can serve as an important reinforcement tool, especially for complex medications or those with significant side effects and interactions. However, their effectiveness depends on whether patients actively read and understand the information provided, rather than setting it aside or relying solely on verbal instructions.

The FDA’s most serious safety alerts are known as black box warnings, which are placed on medications that carry a significant risk of serious or life-threatening effects. Yet only 37.83% of survey respondents said they were familiar with black box warnings.

Among those who did recognize the warning, nearly half reported that it influenced their decision about whether to take a medication. This suggests that awareness can strongly shape behavior. However, the fact that most respondents aren’t familiar with these warnings highlights a broader gap in health literacy, attention to safety information and access to clear, easy-to-understand guidance.

Whitney Ray Di Bona, Attorney & Consumer Safety Advocate for Drugwatch, said black box warnings are only effective if patients actually see and understand them. “Black box warnings exist because a drug poses a real risk of serious harm or death. That is as serious as it gets from a regulatory standpoint,” Di Bona said. “But if only one in three Americans has ever heard of them, the warning is not doing its job. The problem is not that patients are careless. It is that we have built a drug safety system that hides its most critical information in a document most people throw away without opening.”

Survey respondents reported high levels of trust in their doctors and pharmacists. In many cases, that trust is well justified given the expertise and role of healthcare providers in guiding treatment decisions. However, the responses also suggest that trust does not always guarantee full understanding or active engagement with medication instructions. Here is what some respondents had to say:

This level of trust can create a false sense of security. When patients assume all necessary information has already been covered by their provider, they may be less likely to carefully read medication labels or ask follow-up questions. However, trust alone does not prevent medication errors. Staying actively engaged remains essential, including carefully reviewing drug labels and instructions. Medication mistakes, miscommunication and drug interactions are significant contributors to emergency room visits and hospitalizations.

Understanding a medication label goes beyond quickly scanning instructions. Both prescription and over-the-counter labels contain critical safety information that helps prevent dosing errors, interactions and avoidable side effects. Taking a few extra moments to review key sections can significantly reduce the risk of misuse.

Active Ingredients and Dosage Limits

Start with the active ingredients, typically listed just below the brand name. These determine what the medication contains, and tracking ingredients across all products you use is essential. Many medications, especially cold, flu and pain relievers, contain overlapping ingredients under different brand names. Without realizing it, this can lead to unintentional duplication and exceeding safe daily limits.

For example, acetaminophen is commonly found in multiple products. The typical maximum daily dose should not exceed 4,000 mg for most adults. That can be reached quickly with repeated use of extra-strength tablets, even before accounting for other combination medications. Staying aware of cumulative intake is critical to avoid liver toxicity and other serious complications.

Black Box Warnings and Contraindications

Some medications carry FDA black box warnings, the agency’s strongest safety warning for prescription drugs. These warnings highlight serious or potentially life-threatening risks and should always be read carefully, not skimmed or ignored.

Equally important are contraindications, which identify situations where a medication should not be used, such as certain chronic conditions, allergies or dangerous drug interactions. These are not simply precautionary notes, but critical safety guidelines that help determine whether a medication is appropriate for a patient.

Some of the strongest warnings found on medication labels today were added after reports of serious injuries, FDA investigations or growing safety concerns linked to real-world patient outcomes. For example, Ozempic carries a boxed warning about the potential risk of thyroid tumors. At the same time, Depo-Provera includes a black box warning for significant bone mineral density loss with prolonged use. Both medications have also been the subject of ongoing safety concerns and litigation involving alleged failures to adequately warn patients about potential risks.

Drug Interactions and Medication Overlap

Medication safety also depends on understanding how different substances interact. This includes not only prescriptions, but also over-the-counter medications, vitamins and herbal supplements. Interactions can reduce effectiveness, increase side effects or create new health risks when combined.

Because of this complexity, it’s important to carefully review labels and ensure all medications are considered together, not in isolation.

When To Speak With a Pharmacist

In many cases, a quick conversation can clarify instructions, prevent errors and reduce unnecessary risk.

The Bottom Line

Medication labels are designed to protect patients, but only when they are fully read and understood. Taking a few extra minutes to review active ingredients, warnings and interactions and asking questions when uncertain can make a meaningful difference in safe medication use.
