It starts as a dull, annoying throb in your lower back. You think maybe you pulled a muscle at the gym or slept weird on the couch. Then, within twenty minutes, it transforms into a white-hot, stabbing agony that makes you want to crawl out of your own skin. This is the reality of renal colic. If you are reading this while pacing your living room or hunched over a toilet, you just want to know what to take for kidney stone pain so the world stops spinning.
It hurts. A lot. Honestly, doctors often compare the intensity of passing a stone to childbirth or being stabbed. The pain isn't actually from the stone scratching you—though that's a common myth—but from the stone blocking the flow of urine, which causes your kidney to swell and your ureter to spasm violently.
The First Line of Defense: Over-the-Counter Options
Most people reach for Tylenol. Don't. While acetaminophen can help a little, the gold standard for kidney stone pain is actually nonsteroidal anti-inflammatory drugs, or NSAIDs.
Why? Because NSAIDs like ibuprofen (Advil, Motrin) or naproxen (Aleve) do something Tylenol can't: they inhibit prostaglandins. Prostaglandins are the chemicals that tell your ureter to swell and spasm. By blocking them, you aren't just masking the pain; you’re actually calming the pipe that’s trying to squeeze a jagged rock through a space the size of a coffee straw.
A landmark study published in the Annals of Emergency Medicine actually found that NSAIDs are just as effective, if not more effective, than opioids for kidney stone pain. Plus, they don't make you nauseous or dizzy, which is a huge win when you’re already feeling like you might throw up.
But there’s a catch.
If you have a history of kidney disease or impaired kidney function, you have to be incredibly careful. NSAIDs work by reducing blood flow to the kidneys. If your kidney is already under massive pressure from a blockage, slamming a high dose of ibuprofen can occasionally cause more harm than good. Always check with a doctor if you’ve got pre-existing kidney issues.
What Your Doctor Might Prescribe
Sometimes the over-the-counter stuff just doesn't touch it. When you end up in the ER—which many stone-passers do—the toolkit gets a bit heavier.

Ketorolac, often known by the brand name Toradol, is basically an NSAID on steroids. It's usually given through an IV or an injection in the arm. It is, quite frankly, a miracle drug for renal colic. It hits fast. It stops the spasms. It lets you breathe again.
Then there are alpha-blockers. You might have heard of Tamsulosin (Flomax). Technically, it’s a prostate medication, but doctors prescribe it "off-label" for kidney stones all the time. It relaxes the muscles in the lower part of your ureter. Think of it like greasing the tracks. It doesn't kill the pain directly, but by helping the stone move faster and reducing the pressure, the pain subsides naturally.
Some people wonder about opioids. While they are sometimes used for breakthrough pain, many urologists, including those at the Mayo Clinic, prefer to steer clear if possible. Opioids slow down your gut, cause constipation, and can make the vomiting that often accompanies kidney stones even worse.
The Heat Factor and Hydration Myths
You've probably heard that you need to "chug water" to flush the stone out.
Stop.
If your ureter is completely blocked, chugging a gallon of water is like pouring more liquid into a clogged sink. It just builds up more pressure in the kidney, which leads to—you guessed it—more pain. You should stay hydrated, but don't overdo it until the stone starts moving again. Sip, don't chug.
A heating pad is your best friend. Seriously. High heat applied to the flank or abdomen can confuse the pain signals going to your brain. It’s a simple, non-drug way to take the edge off while you’re waiting for the meds to kick in.

When "What to Take" Becomes "Where to Go"
There is a point where home remedies and pills aren't enough. You need to know the red flags.
If you have a fever or chills, stop reading and go to the ER. A stone combined with an infection is a medical emergency called urosepsis. It can get life-threatening fast. Similarly, if you are vomiting so much that you can't keep your pain meds down, you're going to get dehydrated and the pain will win. Get an IV.
Understanding Why What You Take for Kidney Stone Pain Matters
It isn't just about comfort; it's about management. The goal is to keep you out of the operating room if the stone is small enough to pass on its own (usually under 5mm).
The Role of Antispasmodics
In some countries, doctors prescribe Buscopan or other antispasmodics. These aren't as common in the U.S., but the logic is the same: stop the cramping. The ureter is a muscular tube. When it feels a stone, it freaks out and clamps down. Anything that stops that clamp-down is going to be your savior.
Why Lemon Juice Isn't a Painkiller
You’ll see a lot of "natural" advice online about drinking apple cider vinegar or lemon juice to "dissolve" the stone instantly.
Let's be real: that's not how biology works.
Citric acid can help prevent future stones by binding to calcium in the urine, but it’s not an acid-wash that’s going to melt a stone that is currently stuck in your mid-ureter. Drink the lemon water for your long-term health, sure, but don't expect it to stop the stabbing pain in your side right now.

The "Jump and Bump" Technique
This sounds ridiculous. It basically involves drinking a decent amount of water, taking your pain meds, and then literally jumping up and down or landing hard on your heels.
Does it work? Some urologists actually suggest it. Gravity is a real thing. If the stone is hovering at a narrow junction, a little mechanical vibration can sometimes help it scoot along. Just make sure you’ve taken your ibuprofen first, or you’re going to regret every single landing.
A Note on Different Stone Types
What you take for kidney stone pain might also depend on what the stone is made of, though you usually don't know that until it’s out.
Calcium oxalate stones are the most common. Uric acid stones, however, are unique because they can sometimes be dissolved with medication like potassium citrate. These medications turn your urine from acidic to alkaline. If your doctor suspects a uric acid stone, they might put you on a regimen to literally melt the stone over weeks. But for the acute, "I can't breathe" pain? The protocol remains NSAIDs and heat.
Real-World Advice for the Next 24 Hours
If you are currently in the thick of it, here is the play-by-play.
Check your temperature. If it's normal, move to step two. Take an NSAID if your kidneys and stomach can handle it. Get a heating pad on high and wrap it around your side. Try to find a position that works—some people find the "fetal position" on the floor helps, while others need to pace.
Keep a strainer handy. You want that stone. If you catch it, the lab can tell you exactly what it’s made of, which means you can change your diet and never, ever have to search for "what to take for kidney stone pain" again.
Actionable Steps for Immediate Relief
- Prioritize NSAIDs: Use ibuprofen or naproxen over acetaminophen unless contraindicated by your doctor.
- Apply Focused Heat: Use a heating pad or a hot bath to dull the nerve response in the flank area.
- Monitor Your Output: If you stop peeing entirely, that’s a sign of a total blockage. Get to a professional.
- Sip, Don't Slam: Maintain hydration to keep the kidneys functioning, but avoid "water loading" which can increase pressure-induced pain.
- Flowmax (Tamsulosin): Ask your doctor for a prescription to help relax the ureter and speed up the stone's exit.
- Screen Your Urine: Use a stone strainer every single time you go. Knowing the stone's composition is the only way to prevent the next one.
The pain will eventually end. Most stones pass within a few days, though larger ones can take weeks. Stay on top of the dosing schedule for your pain meds—don't wait for the pain to come back full-force before taking the next dose. Keep the inflammation down, keep the muscles relaxed, and ride it out.
