Common over-the-counter pain relievers like ibuprofen (Advil, Motrin), naproxen (Aleve), and aspirin (in higher doses) belong to a class of drugs called NSAIDs (nonsteroidal anti-inflammatory drugs). While they effectively reduce pain, fever, and inflammation, doctors and health authorities have long warned about potentially serious side effects, particularly with regular, high-dose, or long-term use.
Recent articles and doctor comments (including NHS GPs and cardiologists in 2025–2026) have reiterated these concerns, emphasizing risks like heart problems, stomach bleeding, and kidney damage.
Key Risks Highlighted by Doctors and Regulators
The FDA strengthened its warnings on non-aspirin NSAIDs years ago, and the core messages remain consistent:
- Increased risk of heart attack and stroke — This can occur even with short-term use (as early as the first few weeks) and rises with higher doses or longer duration. The risk applies to people with or without prior heart disease, though it’s higher in those with existing cardiovascular issues. Ibuprofen and naproxen have been linked to elevated blood pressure and cardiovascular events.
- Gastrointestinal (GI) bleeding, ulcers, and perforation — NSAIDs can irritate the stomach lining, leading to ulcers or dangerous bleeding. This risk is higher when combining multiple NSAIDs (e.g., ibuprofen with naproxen or aspirin) or when taken with blood thinners.
- Kidney damage — NSAIDs reduce blood flow to the kidneys, which can cause acute kidney injury, especially in dehydrated people, older adults, or those with pre-existing kidney problems. Taking them before intense exercise (when dehydrated) amplifies this risk.
- Other concerns — Fluid retention, high blood pressure, heart failure exacerbation, and interactions with medications (e.g., reduced effectiveness of some blood pressure drugs or increased bleeding risk with aspirin used for heart protection).
Important nuance on aspirin: Low-dose aspirin (often 81 mg) is frequently used for heart protection and carries a lower cardiovascular risk in that context. Higher doses used for pain share more of the NSAID risks. Doctors often advise against combining regular-dose aspirin with other NSAIDs without guidance.
Who Is at Higher Risk?
- People with heart disease, high blood pressure, or prior heart attack/stroke.
- Older adults (risk increases with age).
- Those with kidney disease, stomach ulcers, or bleeding disorders.
- People taking blood thinners, steroids, or certain blood pressure medications.
- Dehydrated individuals or those engaging in intense physical activity.
Practical Advice from Health Authorities
- Use the lowest effective dose for the shortest time needed.
- Avoid combining multiple NSAIDs unless specifically advised by a doctor.
- Consider alternatives for chronic pain: acetaminophen (Tylenol/paracetamol) for many people, topical pain relievers, physical therapy, or non-drug options like heat/ice, exercise, or weight management.
- Stay hydrated and monitor for warning signs: chest pain, shortness of breath, sudden weakness, black/tarry stools, severe stomach pain, swelling, or reduced urine output.
- Talk to your doctor or pharmacist before regular use, especially if you have risk factors or take other medications.
Bottom Line
Ibuprofen, naproxen, and high-dose aspirin are effective for occasional pain, but they carry real risks, particularly to the heart, stomach, and kidneys, which increase with dosage and duration. Recent warnings from doctors (including NHS GPs and cardiologists) remind us to use these medications cautiously rather than as a daily solution.
If you frequently rely on these medications, discuss safer long-term options with your healthcare provider. They can evaluate your personal risks and benefits.
