Ketorolac Risks: What You Need to Know Before Taking This Painkiller

When you need strong pain relief fast, ketorolac, a potent nonsteroidal anti-inflammatory drug (NSAID) used for short-term severe pain. Also known as Toradol, it works fast—often better than opioids for acute pain like after surgery or serious injury. But this power comes with serious risks you can’t afford to ignore. Unlike regular painkillers, ketorolac isn’t meant for daily use. It’s a short-term tool, and using it longer than five days dramatically increases your chance of life-threatening problems.

The biggest danger? stomach bleeding, a severe side effect caused by ketorolac’s effect on protective stomach lining. This isn’t just upset stomach—it’s internal bleeding that can happen without warning, especially in older adults or those with a history of ulcers. Then there’s kidney damage, a hidden risk that strikes silently, especially in people with dehydration, heart failure, or existing kidney issues. Ketorolac reduces blood flow to the kidneys, and in vulnerable people, that can lead to sudden kidney failure. Even healthy people aren’t immune if they take it too long or too often.

It also messes with your blood’s ability to clot. That means if you get cut, bruised, or have surgery, you’re more likely to bleed heavily. This is why doctors won’t prescribe it if you’re on blood thinners or have a bleeding disorder. And it doesn’t play nice with other NSAIDs like ibuprofen or naproxen—mixing them ups the danger without adding more pain relief. Even alcohol can turn a safe dose into a medical emergency.

Who should never touch ketorolac? Anyone over 65, anyone with kidney disease, heart failure, or high blood pressure, pregnant women in their third trimester, or people with asthma triggered by NSAIDs. It’s also a bad idea if you’ve had stomach ulcers before—even if they healed years ago. The risks aren’t theoretical. Real patients have ended up in the ER because they thought "it’s just a painkiller" and kept taking it past the five-day limit.

There are safer options for most types of pain. For mild to moderate pain, acetaminophen often works just as well without the bleeding or kidney risks. For inflammation-related pain, short-term use of lower-dose NSAIDs like naproxen, under a doctor’s watch, might be better than jumping straight to ketorolac. And if you’re dealing with chronic pain, physical therapy, nerve-targeted meds, or even simple movement can help more than a risky shot or pill.

The bottom line? Ketorolac is a fire extinguisher, not a candle. Use it only when the pain is burning hot and no other option works—and put it out as soon as possible.
