Over-the-Counter Medications and Blood Pressure: Key Insights
Common Over-the-Counter Drugs That Affect Blood Pressure
Several over-the-counter (OTC) medications and substances can raise blood pressure or interfere with blood pressure control. Nonsteroidal anti-inflammatory drugs (NSAIDs), sympathomimetic amines (such as those found in some cold and allergy medications), and nasal decongestants are among the most frequently reported OTC drugs that can increase blood pressure. These effects can be more pronounced in people with existing cardiovascular conditions, kidney disease, diabetes, or those taking other medications for blood pressure control 36.
Acetaminophen and Blood Pressure
Acetaminophen is widely used for pain and fever relief and is often considered safer than NSAIDs. However, recent research shows that regular use of acetaminophen can lead to a significant increase in systolic blood pressure, especially in people with hypertension or cardiovascular risk factors. The effect on diastolic blood pressure appears to be minimal or not significant 12. This finding suggests that even commonly used OTC pain relievers should be used with caution in people concerned about blood pressure.
Nasal Decongestants and Hypertension
Long-term or excessive use of OTC nasal decongestants can cause persistent high blood pressure. There are documented cases where stopping the use of these decongestants led to normalization of blood pressure, even without other changes in medication. This highlights the potential risk of self-medicating with decongestants, especially for those with a history of hypertension .
Dietary Supplements, Herbal Products, and Self-Medication
A large proportion of people with hypertension regularly use dietary supplements and OTC drugs, including vitamins, minerals, analgesics, and herbal remedies. Many are unaware that these substances can interact with prescribed antihypertensive medications or affect blood pressure control. Women are more likely than men to use these products regularly. Most patients do not consult their doctors about their use of OTC products, and many do not realize the potential for harmful interactions or blood pressure changes 579.
Drug Interactions and Impaired Blood Pressure Control
OTC substances can sometimes interfere with the effectiveness of prescribed blood pressure medications. For example, activated charcoal, an OTC product, can inactivate oral antihypertensive drugs, making blood pressure harder to control. This underlines the importance of reviewing all medications, including OTC products, when managing hypertension .
Awareness and Reporting of OTC Use
Despite the risks, many patients do not report their use of OTC medications or supplements to their healthcare providers. This lack of communication can lead to unrecognized drug interactions and poor blood pressure control. Health professionals should routinely ask about all OTC and supplement use during medication reviews 79.
Conclusion
Many over-the-counter medications and supplements can raise blood pressure or interfere with blood pressure control, especially in people with hypertension or cardiovascular risk. Acetaminophen, NSAIDs, nasal decongestants, and certain supplements are notable examples. Patients and healthcare providers should be aware of these risks, and regular communication about all medications—including OTC products—is essential for safe and effective blood pressure management.
