The widespread belief that medications sold without a prescription (over‑the‑counter/OTC) are automatically safe is both common and potentially dangerous. Because these drugs are sold freely at pharmacies, supermarkets, and convenience stores, many people assume they pose little to no risk. Pain relievers, acid reducers, and cold remedies have become so normalized that people often use them reflexively, without considering possible side effects. However, health authorities and medical professionals caution that easy access does not mean harmlessness. Even trusted OTC drugs can cause harm if taken improperly, excessively, or over long periods without medical guidance—especially if they interact with other medications or underlying health conditions. These concerns are increasingly highlighted by physicians who point out that familiar medicines can quietly undermine long‑term health.

The fundamental issue is not occasional, appropriate use, but the casual and repeated self‑medication that many people practice. Users frequently take OTC drugs without understanding recommended dosage limits, potential interactions with other medications, or the health consequences of prolonged use. Because many adverse effects develop gradually, people may not link new symptoms—such as fatigue, digestive complaints, or changes in blood pressure—to a medication they have taken daily for years. While misinformation about OTC drugs sometimes circulates online, there are real, evidence‑based risks associated with improper or long‑term usage. These risks may not be immediately obvious, but over time they can place strain on vital organs like the heart, liver, and kidneys, potentially contributing to chronic health issues.

One physician drawing attention to these hidden risks is cardiologist Dr. Aurelio Rojas, who uses social media platforms to educate the public. He warns that medications people consider routine—like painkillers, acid reducers, nasal decongestants, and even some antidepressants—are often taken without a second thought. According to Dr. Rojas, the danger lies in their subtle, cumulative effects on the body, particularly when used long after symptoms fade and without professional oversight. His message emphasizes that the most familiar drugs may be the ones people least suspect of causing harm, yet their effects on heart rhythm, blood pressure, and organ function can be real and serious.

A key example Dr. Rojas highlights is omeprazole, a proton pump inhibitor (PPI) widely purchased both by prescription and OTC for conditions like heartburn and acid reflux. While effective at reducing stomach acid, long‑term use of omeprazole has been shown to interfere with the absorption of vital nutrients such as magnesium, iron, and vitamin B12. These nutrients are essential for energy production, nervous system function, and cardiovascular health. Deficiencies may lead to symptoms like fatigue, weakness, and irregular heart rhythms, which develop gradually and may go unnoticed while the medication is still being taken for comfort. The fact that nutrient depletion can subtly weaken bodily systems—especially in the absence of medical monitoring—makes prolonged use of acid reducers potentially harmful.

Another widely used OTC drug is ibuprofen, a nonsteroidal anti‑inflammatory drug (NSAID). Though effective for pain and inflammation, ibuprofen and similar NSAIDs carry documented risks when used frequently or at high doses. Regulatory agencies like the U.S. FDA warn that NSAIDs, including ibuprofen and naproxen, are associated with an increased risk of heart attack and stroke, even in otherwise healthy individuals, especially with prolonged use or higher doses. These cardiovascular risks can occur early in the course of therapy and increase with ongoing use. Additionally, frequent NSAID use can harm the kidneys and gastrointestinal tract, potentially leading to ulcers, bleeding, and kidney dysfunction. Combined with physical stressors such as dehydration, the use of NSAIDs before intense exercise may further elevate the risk of cardiovascular complications.

The broader lesson from these warnings is not that OTC medications should be avoided altogether, but that they must be used with intention, moderation, and medical awareness. They are valuable for managing pain, discomfort, or minor ailments when used according to established guidelines, but they are not inherently risk‑free simply because they are easy to buy. Regular reliance without proper professional input increases the possibility of hidden damage that may only become apparent after the fact. Patients should respect recommended durations of use, heed warning labels, and consult healthcare providers when symptoms persist or when they are taking multiple medications. Convenience should never replace caution, and relief should not come at the expense of long‑term health. Understanding the real risks associated with OTC drugs helps ensure that these powerful tools serve our well‑being rather than undermine it.

In conclusion, over‑the‑counter medications can be powerful allies in everyday health management—but only when their use is informed, intentional, and appropriately monitored. Accessibility does not guarantee safety. Being mindful of dosage limits, potential interactions with other drugs or health conditions, and the possibility of cumulative effects on organs like the heart and kidneys is essential. By acknowledging these risks and approaching OTC medications responsibly, individuals can protect both their comfort today and their health tomorrow.
