How we feel influences daily life at every age. Many people use nonprescription or prescription pain medications at times. This page provides a high-level, educational overview—drawn from public health sources—of common medication classes and selected, non-exhaustive risks. It is not medical advice.

Pain Medications and Side Effects (General Information)

• Acetaminophen

  Commonly used for mild to moderate pain. Selected potential risks reported in the literature include hypersensitivity reactions (e.g., rash), certain hematologic effects (e.g., anemia, leukopenia), kidney effects, and metabolic/electrolyte disturbances.

• Nonsteroidal Anti-inflammatory Drugs (NSAIDs)

  Commonly used for mild to moderate pain, including pain associated with inflammation. Selected potential risks include gastrointestinal problems (nausea, dyspepsia, ulcers, bleeding, perforation), cardiovascular events (hypertension, myocardial infarction, stroke, thromboembolic events), and kidney effects (fluid retention, reduced kidney function, hyperkalemia, analgesic nephropathy).

• Topical Analgesics

  Products applied to the skin are often marketed for localized symptoms. Selected potential risks include application-site reactions (stinging, burning, tingling); certain capsaicin-containing products may also be associated with redness, burning sensation, and systemic symptoms reported in labeling (e.g., nausea, headache, palpitations).

• Opioids

  Reserved for certain severe pain scenarios under medical supervision. Selected potential risks include sedation, constipation, nausea/vomiting, respiratory depression, endocrine effects, tolerance, physical dependence, and risk of misuse and addiction.

General Information: Non-pharmacologic Approaches (Educational)

Public health sources discuss non-pharmacologic approaches that may be considered by patients and their clinicians, such as physical therapy and exercise-based rehabilitation, certain manual therapies, cognitive-behavioral approaches, acupuncture, and massage. Suitability varies by individual and should be determined with a licensed healthcare professional. This information is general and not medical advice.
