When you reach for ibuprofen, naproxen, or aspirin to ease a headache, sore muscles, or joint pain, you’re using a NSAID, a nonsteroidal anti-inflammatory drug used to reduce pain, fever, and inflammation. Also known as nonsteroidal anti-inflammatory drugs, these medications are everywhere—from pharmacies to kitchen cabinets—but they aren’t harmless, even when taken as directed. Many people think because NSAIDs are sold without a prescription, they’re safe for daily use. That’s not true. Long-term or high-dose use can quietly damage your stomach, kidneys, and heart—even if you feel fine.
One of the most common risks is stomach ulcers, open sores in the lining of the stomach or small intestine caused by NSAIDs blocking protective enzymes. Also known as gastric ulcers, they can lead to bleeding, severe pain, or emergency hospital visits—often without warning signs until it’s too late. Older adults, people on blood thinners, or those with a history of stomach problems are at higher risk. But even healthy 30-year-olds who take ibuprofen every day for back pain are putting themselves in danger. The damage builds slowly. You won’t feel it until it’s serious.
Then there’s kidney damage, a hidden threat that affects how your kidneys filter waste and regulate fluid. Also known as NSAID-induced nephrotoxicity, this can happen even with short-term use in people who are dehydrated, have high blood pressure, or already have reduced kidney function. NSAIDs reduce blood flow to the kidneys. For most, that’s no big deal. But for others, it’s enough to trigger acute kidney injury or worsen chronic disease. And unlike liver damage, there’s no clear symptom until your creatinine levels spike at a routine checkup.
And it’s not just your gut and kidneys. NSAIDs can raise your risk of heart attack or stroke, especially if you take them for months or years. The FDA has warned about this for over a decade. People with existing heart disease should avoid them unless a doctor says otherwise. Even over-the-counter doses add up. Taking two Advil a day for your arthritis? That’s a daily dose. Not occasional. Not harmless.
Some people also get ringing in the ears, dizziness, or high blood pressure. Others develop allergic reactions—rashes, swelling, or trouble breathing. These aren’t rare. They’re common enough that every pharmacy label warns about them. But most people skip reading the fine print.
What’s missing from the conversation is that there are safer ways to manage pain. Physical therapy, heat therapy, acetaminophen for mild pain, or even low-dose antidepressants for chronic pain can work without the same risks. You don’t have to choose between pain and damage. You just need to know the trade-offs.
Below, you’ll find real-world breakdowns of how NSAIDs interact with other drugs, who’s most at risk, and what alternatives actually work. No fluff. No marketing. Just what you need to protect yourself while still getting relief.
Ibuprofen and naproxen are common OTC painkillers, but they carry serious risks like heart attack, stomach bleeding, and kidney damage. Learn the safe limits, who should avoid them, and what to do instead.
