What are NSAIDs?
Nonsteroidal anti‑inflammatory drugs (NSAIDs) are medicines that reduce pain, inflammation, and fever. They’re widely used for short‑term aches (sprains, headaches, menstrual cramps) and longer‑term conditions like osteoarthritis or rheumatoid arthritis. Most NSAIDs work by blocking cyclooxygenase (COX) enzymes—COX‑1 and COX‑2—which your body uses to make prostaglandins, chemicals that drive pain, swelling, and fever. By lowering prostaglandins, NSAIDs decrease inflammatory signaling.
Key idea: COX‑1 helps protect the stomach lining and support kidney function; COX‑2 is more tied to inflammation and pain. Blocking COX‑2 relieves pain, but blocking COX‑1 can raise stomach and kidney risks.
What do NSAIDs treat?
People turn to NSAIDs for:
Musculoskeletal pain: back/neck pain, sprains and strains, tendonitis, bursitis.
Arthritis: osteoarthritis, rheumatoid arthritis, ankylosing spondylitis.
Headache & migraine, dysmenorrhea (period cramps), dental or post‑operative pain.
Fever linked to common illnesses.
When to consider alternatives:
If you have a history of stomach ulcers/bleeding, heart disease, stroke, uncontrolled hypertension, chronic kidney disease, or are pregnant—NSAIDs may not be appropriate or may require close medical guidance.
Types of NSAIDs
By selectivity
Traditional (nonselective) NSAIDs block both COX‑1 and COX‑2 (e.g., ibuprofen, naproxen, diclofenac).
COX‑2–selective inhibitors (e.g., celecoxib) aim to reduce pain/inflammation with less stomach irritation—but CV and kidney risks can still occur.
By availability
OTC NSAIDs: aspirin, ibuprofen, naproxen (varies by country).
Prescription NSAIDs: higher‑dose ibuprofen/naproxen, diclofenac, indomethacin, meloxicam, celecoxib, ketorolac, piroxicam, etodolac, nabumetone, flurbiprofen, oxaprozin, mefenamic acid, sulindac, tolmetin, ketoprofen. (Lists differ by region.)
By route
Oral tablets/capsules/suspensions
Topical gels/patches (e.g., diclofenac gel) for localized joint or soft‑tissue pain, which can lower systemic exposure.
Common examples
Ibuprofen (OTC & Rx): versatile short‑acting option for mild–moderate pain/fever.
Naproxen (OTC & Rx): longer acting; often 12‑hour dosing.
Diclofenac (Rx oral; OTC topical in some regions): effective for arthritis; topical versions reduce systemic exposure.
Meloxicam (Rx): once‑daily; often for arthritis.
Celecoxib (Rx COX‑2 selective): stomach‑sparing intent; CV/renal cautions still apply.
Ketorolac (Rx): potent short‑term NSAID; strict duration limits due to GI/renal risk.
How to use NSAIDs safely
Use the lowest effective dose for the shortest time. This principle appears across medical guidance to limit side effects.
Take with food if the label advises, and stay hydrated to support kidneys.
Avoid doubling up on multiple NSAIDs (e.g., don’t take ibuprofen + naproxen together).
Don’t mix with alcohol, which can compound stomach bleeding risk.
Consider gastroprotection (e.g., a PPI) if you must use NSAIDs and have GI risk factors—discuss with your clinician.
Follow labeled daily limits and doctor advice.
Topical first for localized joint pain (e.g., hand/knee OA) to reduce systemic exposure.
Side effects & risks
Common: stomach upset, heartburn, dizziness, fluid retention or swelling. Consumer‑facing pages (Cleveland Clinic, NHS) list these routinely.
Serious (seek medical care):
Gastrointestinal (GI) damage:
NSAIDs can cause ulcers, bleeding, or perforation in the esophagus, stomach, or intestines—sometimes without warning. Risks increase with longer use, higher doses, age, prior ulcer/bleed, smoking, alcohol, and combining with steroids/anticoagulants/SSRIs.Cardiovascular (CV) events:
The FDA strengthened label warnings that non‑aspirin NSAIDs increase the risk of heart attack and stroke; risk can rise even within the first weeks of use and with higher doses/longer duration. This caution applies especially to people with existing heart disease.Kidney effects:
NSAIDs can reduce kidney blood flow, potentially causing acute kidney injury or worsening chronic kidney disease, particularly in those with dehydration, diuretic/ACEi/ARB use, older age, or comorbid kidney disease.Blood pressure & fluid retention:
NSAIDs may raise blood pressure and promote edema, affecting heart failure management and antihypertensive control.Respiratory/hypersensitivity:
In people with aspirin‑sensitive asthma or certain nasal polyps disorders, NSAIDs can trigger bronchospasm.
Red flags—stop and contact a clinician or seek urgent care:
Black/tarry stools, vomit that looks like coffee grounds, severe stomach pain
Chest pain, shortness of breath, weakness on one side, slurred speech
Sudden swelling, rapid weight gain, severe headache, confusion
Very little urine, or new/worsening ankle swelling
Drug interactions
Anticoagulants/antiplatelets (e.g., warfarin, some DOACs), aspirin: ↑ bleeding risk.
SSRIs/SNRIs: additive GI bleeding risk.
Corticosteroids: ↑ GI ulcer/bleed risk.
ACE inhibitors/ARBs + diuretics: the “triple whammy” can reduce kidney perfusion → AKI.
Lithium: NSAIDs can ↑ lithium levels → toxicity risk.
Methotrexate (high doses): impaired clearance possible.
Alcohol: ↑ GI bleeding risk.
Always check labels and consult a clinician/pharmacist if you take heart, blood pressure, mood, rheumatology, or anticoagulant medicines.

Special populations
Pregnancy & breastfeeding
Routine NSAID use is generally discouraged in pregnancy, especially in the third trimester (risk of fetal ductus arteriosus closure and kidney issues). Some guidelines also caution in the first/second trimesters unless clearly needed.
Breastfeeding: some NSAIDs are considered compatible at usual doses, but medical advice is recommended. Always follow clinician guidance and local labeling. (Consumer and national health sites reflect these cautions.)
Older adults
Heightened risks for GI bleeding, kidney injury, and CV events; use only if necessary, at the lowest dose/shortest duration, consider topical routes, and add gastroprotection if appropriate.
Children
Ibuprofen is commonly used at weight‑based doses for fever/pain; aspirin is generally avoided in children due to Reye’s syndrome risk in specific viral illnesses (follow pediatric guidance). (Use local pediatric dosing and labeling.)

WE ACCEPT MOST INSURANCES
NSAIDs vs. acetaminophen (paracetamol)
Acetaminophen reduces pain/fever but not inflammation; it’s gentler on the stomach and doesn’t carry the same CV/renal concerns, but can harm the liver if overused or combined with alcohol.
If you need anti‑inflammatory action (e.g., joint swelling), an NSAID can be more effective; if you primarily need pain/fever relief, acetaminophen may be a safer first option for some people. (Choose based on your health profile and clinician advice.)
Topical NSAIDs: a safer entry point for joints
Topical diclofenac gel/patches deliver NSAID only where you need it, with lower systemic exposure and fewer GI effects for hand/knee osteoarthritis and some soft‑tissue pains. They’re a strong first‑line option when pain is localized
When NOT to use an NSAID (without medical advice)
Active or recent GI bleeding/ulcer
Recent heart attack, unstable heart disease, post‑CABG pain control
Advanced kidney disease or unexplained swelling/rapid weight gain
Late pregnancy
Known NSAID/aspirin hypersensitivity
Uncontrolled hypertension

Frequently Asked Questions About Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Uses, Risks, Safety, and Alternatives
What are NSAIDs and how do they work?
They reduce pain, fever, and inflammation mainly by blocking COX enzymes that make prostaglandins.
What are common NSAIDs?
Aspirin, ibuprofen, naproxen, diclofenac, indomethacin, meloxicam, celecoxib, ketorolac, piroxicam, and others (availability varies by country).
Which NSAID is safest for the heart?
No NSAID is risk‑free. Non‑aspirin NSAIDs carry an increased heart attack/stroke risk, especially at higher doses/longer use or in people with heart disease. Discuss personalized options with your clinician.
Which NSAID is easiest on the stomach?
COX‑2–selective agents (e.g., celecoxib) were designed to reduce GI effects, but GI bleeding can still happen and CV/renal risks remain. Use the lowest effective dose and consider gastroprotection if at risk.
Can I take NSAIDs every day?
Long‑term daily use raises risks (GI, CV, kidney). If you need frequent NSAIDs, see your clinician to reassess therapy, dosing, and protective strategies.
Are NSAIDs safe in pregnancy?
Generally avoid, especially in the third trimester. Seek medical advice before use at any stage of pregnancy; follow local labels.
Can I drink alcohol while taking NSAIDs?
Alcohol increases stomach bleeding risk with NSAIDs; avoid the combination.
Do NSAIDs raise blood pressure?
They can increase blood pressure and cause fluid retention, particularly important for those with hypertension or heart failure.
Can I take ibuprofen with aspirin or another NSAID?
Avoid doubling up on NSAIDs. Combining with aspirin may raise bleeding risk and can affect aspirin’s antiplatelet effect (timing matters). Ask your clinician/pharmacist.
Are topical NSAIDs effective?
Yes—for localized joint pain (e.g., knee/hand OA) they can be effective with lower systemic risk compared with oral forms.
