Ketorolac, often known as Toradol, is a strong anti-inflammatory painkiller that hospitals give to children by IV or injection for short bursts of pain. There is no single legal minimum age, because the official label approves it only for adults. A child’s eligibility rests on hospital practice and medical evidence rather than a printed cutoff, so the useful question is less “how old?” and more “how big, how long, and are this child’s kidneys and bleeding risk suitable?” In practice, many hospitals give it to children over about 6 months, and especially to those over 1 year, at a weight-based dose for a few days. Infants under 1 year generally aren’t given it outside specialist care.
What the Label Says Versus What Hospitals Do
The US label says injectable ketorolac is not intended for children.1DailyMed / FDA Label. Ketorolac Tromethamine Injection, USP It also says the drug is not for minor or long-lasting pain, so its approved role is short-term treatment of moderate-to-severe pain.2DailyMed / FDA Label. Ketorolac Tromethamine Injection, USP Safety and effectiveness have not been formally established under age 17, and the nasal spray should not be used under age 2.
Hospitals use it below 17 anyway. Doctors often use medicines in ways the label doesn’t list, and this is legal and routine in children’s medicine. Drug makers rarely run the costly trials needed to win approval for children, so doctors rely on published studies and hospital protocols instead. Children’s hospitals keep their own ketorolac dosing guides.3Children’s Mercy Kansas City. Ketorolac Ongoing trials give it to children as young as 6,4JMIR Publications.

The label’s silence on children mostly reflects that the manufacturer never sought a pediatric approval, not that regulators found the drug unsafe for kids. It’s also why two reputable hospitals can have slightly different rules, such as different lower age limits or maximum days.
In most hospitals the drug is ordered through a protocol or order set reviewed by pharmacists and physicians, not chosen casually at the bedside. Pharmacists usually check the dose against the child’s weight before it is given.
If a nurse mentions Toradol, you can ask whether it is part of the hospital’s usual protocol for your child’s age, and how many days it is planned for. Mention any kidney problems, bleeding problems or stomach ulcers, and say if your child already had ibuprofen today.
The Practical Age Floor Infants Under One
Expert reviews of ketorolac for children’s post-surgery pain advise against using it in infants under 1 year.6PubMed. Ketorolac for postoperative pain management in children Babies’ kidneys and their ability to clear drugs are still maturing during that first year. Infant kidneys filter blood more slowly than older children’s, so a drug can stay in the body longer. Anti-inflammatory painkillers can also reduce blood flow within the kidney, which matters more when the kidneys are immature. Clinicians who have other painkillers usually choose those for babies.
Some specialist units still use it in tiny babies. Published reports describe about 240 infants younger than 6 months who received ketorolac after surgery, and most received 0.5 mg per kg every 6 hours for 2 to 3 days.7PubMed Central. Ketorolac in Postoperative Neonates and Infants: A Systematic Review In premature babies it has been tried to close a heart vessel that stays open after birth, without bleeding or reduced urine in that small group.8Acta Medica Philippina. Comparison of Ketorolac and Indomethacin for the Closure of Patent Ductus Arteriosus among Preterm Infants Born at the Philippine General Hospital: A Randomized Controlled Crossover Design These are closely monitored intensive-care settings, not general practice.
If your baby is in the NICU or cardiac unit, the team may use ketorolac for a short, monitored course. They check urine output and blood tests during it, and you can ask what the plan is if urine drops.
Acetaminophen, dosed by weight, is the usual first choice for pain in babies. After bigger operations, doctors may use carefully dosed opioids or numbing medicine given near the surgical site, which they can monitor closely. If a baby under one is offered ketorolac, it is fair to ask why it was chosen over these options and who will be monitoring the baby.
After infancy, weight matters more than age. Doses are set per kilogram, so a small 3-year-old gets less than a large one, and a teenager may reach the adult dose ceiling.
Kidney and Stomach Risks for Children
Ketorolac belongs to the same family of anti-inflammatory painkillers as ibuprofen. In a large group of children hospitalized with sudden kidney injury, about 3 in 100 cases were blamed on these drugs, or about 7 in 100 once complex cases were excluded.9PubMed. Nonsteroidal anti-inflammatory drugs are an important cause of acute kidney injury in children Three in four of those children had taken normal doses.10PubMed. Nonsteroidal anti-inflammatory drugs are an important cause of acute kidney injury in children Children under 5 with this kind of kidney injury all needed dialysis and most needed intensive care.11PubMed. Nonsteroidal anti-inflammatory drugs are an important cause of acute kidney injury in children In children with sickle cell disease, kidney injury on ketorolac didn’t depend on dose, and many already had high creatinine, a blood test of kidney function, when they arrived.12Hematology Advisor. Ketorolac Dosage May Not Predict Acute Kidney Injury Risk in Patients With Sickle Cell Disease
Normal doses can still cause trouble because kidneys depend partly on natural chemicals to keep blood flowing well, especially when the body is short of fluid. These painkillers block those chemicals, so blood flow to the kidney can drop.
Before or during treatment, a kidney blood test can show whether the kidneys are filtering normally. A rising number between tests suggests the kidneys are struggling, and the drug is usually stopped. In a healthy child having routine surgery, doctors may skip the test, but it matters more for children with known kidney disease, sickle cell disease or dehydration.
Kids who are vomiting or not drinking are more vulnerable, and IV fluids are often given alongside. It is reasonable to ask whether your child has been drinking enough before doses continue. Children with existing kidney disease, and those taking other medicines that affect the kidneys, also carry more risk. Other anti-inflammatory drugs given at the same time add to the load and should not be stacked without the team knowing, so tell them about every medicine and supplement your child takes, including over-the-counter ones.
Ketorolac can also cause stomach or bowel ulcers and bleeding that may come with no warning.13UpToDate Lexidrug. Ketorolac: Pediatric drug information Past ulcers or bleeding raise the risk,14UpToDate Lexidrug. Ketorolac: Pediatric drug information and that is a key reason courses are kept to a few days.
Tell the nurse at once if you notice your child peeing much less than usual or passing dark urine, swelling of the face or legs, black tarry stool, or vomit that contains blood or looks like coffee grounds.
Bleeding Risk After Surgery Including Tonsillectomy
Children given ketorolac on the day of tonsil surgery were about twice as likely to have early bleeding needing a return to the operating room.15PubMed. Effect of perioperative ketorolac on postoperative bleeding after pediatric tonsillectomy Later bleeding risk rose somewhat in one analysis,16PubMed. Effect of perioperative ketorolac on postoperative bleeding after pediatric tonsillectomy but another analysis found no rise in later bleeding.17PubMed. Dose-Related Effects and Bleeding Risk of Ketorolac in Pediatric Tonsillectomy The extra early bleeding came with doses of about 1 mg per kg, not 0.5 mg per kg.18PubMed. Dose-Related Effects and Bleeding Risk of Ketorolac in Pediatric Tonsillectomy
The tonsil area is a raw wound that cannot be bandaged or pressed on, so any slowing of clotting shows up there. Ketorolac slows platelets, the cell fragments that plug small bleeding points, and this effect wears off over a day or two rather than instantly. That helps explain why surgeons argue about it for tonsillectomy even though many other operations show no clear problem. Twice as likely applies to a small starting risk, so most children given ketorolac still do not bleed.
Other operations look different. In children having brain and spine surgery, routine ketorolac wasn’t linked to bleeding.19PubMed. Routine perioperative ketorolac administration is not associated with hemorrhage in pediatric neurosurgery patients
Before tonsil surgery, ask whether ketorolac is planned and at what dose. Ask about ibuprofen at home too, since surgeons handle it differently. At home, bright red blood from the mouth, repeated swallowing with blood in the saliva, or vomiting blood needs an emergency visit, not a wait-and-see approach. A little pink streaking in saliva around the time the scabs loosen may be expected, but follow the surgeon’s discharge instructions, which usually say which painkillers are allowed.
How the Dose Is Worked Out
- IV: 0.5 mg per kg, maximum 30 mg.20Children’s Mercy Kansas City. Ketorolac
- Muscle injection: 1 mg per kg, maximum 60 mg.21Children’s Mercy Kansas City. Ketorolac
- Infants in specialist care: 0.5 mg per kg every 6 hours for 2 to 3 days.22PubMed Central. Ketorolac in Postoperative Neonates and Infants: A Systematic Review
The nurse or pharmacist multiplies the child’s weight in kilograms by the per-kilogram dose, then compares the result with the maximum. If it goes over, the maximum is given instead. The weight used is a measured current weight, which is why children are often weighed on arrival. A 20 kg child gets about 10 mg IV, while a 70 kg teen hits the 30 mg cap.
IV doses go into a vein, so they act faster and use the lower per-kilogram amount. The muscle injection uses the higher amount and is mostly used when there is no IV, but it is more painful for the child. You can ask which route is planned and why.
Doses are usually given on a schedule about six hours apart, rather than whenever pain flares. Courses are intentionally short, usually capped at around 5 days total, because the risks of kidney and bleeding problems rise with longer use. Expect the team to name a stop date or reassess daily, and ask if they haven’t. If ketorolac tablets are prescribed for home, don’t give them alongside ibuprofen or naproxen.
Lower doses may work too. Trials are testing whether 0.25 mg per kg or a 10 mg cap relieves pain as well as the standard dose in children 6 to 17.23CrossRef / JMIR Publications. Comparison of Ketorolac at 3 Doses in Children With Acute Pain: Protocol for A Randomized Controlled Trial (Preprint) Lower doses might cut side effects such as the tonsil bleeding seen at higher doses.
Does It Work and What Are the Alternatives
After hernia surgery, under 3 in 10 children given ketorolac plus acetaminophen needed rescue fentanyl, versus 8 in 10 without it.24PubMed.

Acetaminophen is gentler on kidneys and stomach, and combining it with ketorolac is common and sensible. Ibuprofen is a close cousin, so its kidney, stomach and bleeding risks are similar in kind. Ketorolac is stronger and comes by injection, which suits short severe pain when a child is vomiting or can’t swallow pills. If a child can swallow and the pain is moderate, ibuprofen by mouth may do the job.
You can ask whether a non-opioid option fits your child, and what happens if pain persists. Mention any allergy or reaction to aspirin or ibuprofen, which usually rules ketorolac out.
