NSAIDs: What They Do and How to Use Them Safely

NSAIDs are the pain relievers most of us reach for first—ibuprofen, naproxen, aspirin, and similar drugs. They ease pain and swelling by blocking enzymes (COX-1 and COX-2) that cause inflammation. That makes them great for headaches, muscle aches, menstrual cramps, and arthritis flares. But they’re not harmless: using the wrong dose, mixing meds, or having certain health issues can cause real problems.

Common NSAIDs and Typical Uses

Over-the-counter choices: ibuprofen (Advil, Motrin) and naproxen (Aleve) are the go-to options for short-term pain and fever. Aspirin works for pain and is used at low doses for some heart patients, but don’t mix aspirin with other NSAIDs without a doctor’s OK. Prescription options include higher-dose naproxen, diclofenac, and celecoxib (a COX-2 selective drug). There are also topical NSAID gels and patches (like diclofenac gel) that help local joint or muscle pain with less systemic exposure.

Quick examples: for a tough menstrual cramp, many people find ibuprofen 200–400 mg helps; for longer-lasting joint pain relief, naproxen’s longer action can be more convenient. Always follow the label or your doctor’s directions instead of guessing.

Safety Tips, Interactions, and When to See a Doctor

Start with the lowest effective dose for the shortest time. Take NSAIDs with food to reduce stomach upset. Avoid alcohol while using them—alcohol raises the risk of stomach bleeding. Never combine two NSAIDs at once; that adds risk without extra benefit.

Watch for interactions: NSAIDs can interfere with blood pressure meds (ACE inhibitors, ARBs), increase bleeding risk with blood thinners (warfarin, DOACs), and raise the risk of stomach bleeding with SSRIs. People with kidney disease, active ulcers, uncontrolled high blood pressure, or heart disease should talk to their clinician before taking NSAIDs. Pregnant people—especially in the third trimester—should avoid most NSAIDs unless advised by a doctor.

Signs you need medical advice: black or bloody stools, severe belly pain, shortness of breath, sudden weight gain, swelling in the legs, or new high blood pressure. Also check in with your provider if you need regular NSAIDs for chronic pain—there may be safer alternatives or monitoring that can reduce risk.
