National Survey of 21,000 Adults Captures Seven-Day Snapshot of Medication Use; OTC and Prescription Medicines Used in Tandem to Address Distinct Health Needs

WASHINGTON, Feb. 18, 2026 /PRNewswire/ – _A new, nationally-representative study published in the peer-reviewed medical journal JAMA Network Open provides a detailed picture of U.S. adults’ use of over-the-counter (OTC) and prescription (Rx) medications. The study finds that nearly two-thirds (62%) of U.S. adults — approximately 166.5 million people — reported using at least one medication in the past seven days. Notably, 46% of those surveyed reported the use of an OTC medication during that same period, often to address everyday, self-treatable healthcare. _

Medication use among U.S. adults in the previous seven days. Based on a nationally representative survey of 21,000 adults, responses were statistically weighted to reflect the U.S. adult population.

Rather than focusing on prescriptions written or medications taken at any point during an individual’s lifetime, the study, Prevalence of Over-the-Counter and Prescription Medication Use in the US (Green et al, 2026), captures a snapshot of recent, self-reported use. Within a seven-day period, OTC and prescription medicines were reported at nearly identical rates, reflecting the co-use of different types of medicines within the same week to address distinct health needs.

“These findings show that OTC medicines are an important part of everyday health management for millions of Americans,” said CHPA President and CEO Scott Melville. “As policymakers consider new approaches to improve the accessibility and affordability of healthcare, it’s important to recognize the vital role OTC medicines already play in helping Americans manage healthcare needs. And supporting that role through sound policy, regulatory rigor, and public education remains a CHPA priority.”

“Usually, medication evidence comes from prescriptions dispensed by pharmacies or products sold,” said Jody Green Ph.D., principal investigator of the study, “but in this study we focused on what people actually used in the past seven days, which provides a clearer picture of how American adults manage their health conditions in daily life.”

What the Study Measured

Adults often manage multiple health concerns at once, using more than one medication during a given week. The study evaluated recent, self-reported use of OTC and prescription medications across a range of common conditions, including both single-ingredient and fixed-dose combination products.

No information was collected on the care settings in which medications were taken or on health outcomes. The findings reflect how U.S. adults report managing their individual health needs through the use of both OTC and prescription medications. Prescription medications are commonly used for more serious or longer-term conditions, while OTC medicines are frequently used to manage short-term and everyday ailments.

Story Continues  

**What Americans Use Most **

The published study identified the most commonly used Rx and OTC medicines reported by U.S. adults in the past seven days. The list includes familiar OTC products alongside widely used prescription medicines for chronic conditions, reflecting the mix of self-care and clinician-directed treatments people report using in everyday life. This mix underscores an important reality: healthcare is not an either-or proposition. It is a continuum in which consumers responsibly combine self-care and clinician-guided treatments to meet their needs.

“It’s also notable that several of the most commonly used OTCs on the list were once only available by prescription,” continued Melville. “Over the years, OTC medications_ —_ like naproxen, omeprazole, cetirizine, and loratadine to name a few_ — _went through FDA’s Rx-to-OTC switch process to change their status from prescription-only access to OTC. Their appearance on the list among the most commonly-used medicines is a great example of how smart regulatory changes can expand consumer access to safe and effective treatments for better self-care.”

Notably, the four most commonly used medicines overall_ — acetaminophen, ibuprofen, aspirin, and naproxen — _are all available over the counter, with the top three unchanged from patterns observed in national medication use surveys conducted approximately 25 years ago. The top 20 most commonly used medications include:

OTC Medicines in Everyday Use

One of the key findings of the study is the extent to which OTC medicines are used for self-treatable health concerns. Overall, six of the 10 most commonly used medicines identified in this study are available, or primarily available, as an OTC medication.

OTCs, Self-Care, and Health Policy

These findings provide updated, real-world context on how Americans use both Rx and OTC medicines as part of everyday health management. By documenting recent medication use rather than prescriptions written or products sold, the study offers relevant data to inform ongoing discussions about self-care, access, and the appropriate role of nonprescription medicines within the broader healthcare landscape.

Study Methods

Researchers conducted a large, nationally representative survey of U.S. adults, asking participants to report all prescription and OTC medicines they had used in the previous seven days. Responses were statistically weighted to reflect the U.S. adult population. By focusing on recent use rather than prescriptions written or lifetime recall, the study captures actual medication use within a defined, seven-day reporting period.

Sample size: 21,000 U.S. adults

Timeframe: June 2023 through April 2024

Recall window: Past seven days
