What is Ketorolac?

Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID) used for the short-term management of moderate to severe pain. It is not for minor aches or long-term arthritis. It is the kind of painkiller given after surgery, after a significant injury, or during a severe flare of kidney stone pain. Ketorolac works by blocking the production of prostaglandins, the chemicals that cause pain and inflammation. It is effective and fast, often providing relief comparable to low-dose opioids without the sedation or addiction risk. But that power comes with a strict limit: it should not be used for more than 5 days because of the high risk of stomach ulcers, bleeding, and kidney damage.

Ketorolac is available as a 10 mg tablet, an injectable form, and an eye drop. The 10 mg oral dose is used for pain that has already been controlled by an injection of ketorolac, or as a starting dose in certain situations. It is not meant to be the first-line drug for a sprained ankle or a headache. The 10 mg tablet is often prescribed as one tablet every 4 to 6 hours as needed, with a strict maximum of 40 mg per day and 5 days total. It is a powerful tool for a short, sharp pain crisis, not a daily companion. Ketorolac is available as generic and was originally sold under the brand name Toradol.

Mechanism and Pharmacology

Ketorolac inhibits both COX-1 and COX-2 enzymes, similar to ibuprofen, but it is much more potent on a milligram-for-milligram basis. By blocking these enzymes, it dramatically reduces the production of prostaglandins throughout the body. That knocks down pain and inflammation quickly. But the COX-1 inhibition also strips away the protective prostaglandins in the stomach lining and reduces blood flow to the kidneys. This is why the risk of gastrointestinal bleeding and kidney injury is much higher with ketorolac than with weaker NSAIDs, and why the duration of use is strictly limited.

After oral administration, ketorolac is rapidly and completely absorbed, with peak plasma levels reached in about 35 minutes. Food, especially a high-fat meal, slows absorption but does not reduce the total amount. The drug is highly protein-bound, over 99 percent. It is metabolized in the liver to inactive metabolites and excreted primarily in the urine. The half-life is about 5 to 6 hours in healthy adults, which supports dosing every 4 to 6 hours. In elderly patients and those with reduced kidney function, the half-life is longer, and the dose must be reduced or the drug avoided altogether. Ketorolac crosses the placenta and is not recommended in pregnancy. The 10 mg tablet is a low oral dose, but it still carries the full toxicity profile of the drug.

How to Use Ketorolac

Take one 10 mg tablet every 4 to 6 hours as needed for pain. Do not take more than 40 mg in a 24-hour period. Do not take ketorolac for more than 5 days total. The tablet should be swallowed whole with a full glass of water. Taking it with food or milk helps protect the stomach and reduces nausea. If you miss a dose and you are taking it on a regular schedule, take it as soon as you remember. If it is almost time for the next dose, skip the missed one. Do not double up. This is not a medication where you should catch up on missed doses, because the risk of side effects rises sharply with higher intake.

Ketorolac is usually prescribed after an initial injection of ketorolac or another painkiller. Your doctor will tell you when to start the tablets and how many to take. Do not use it for chronic pain. If your pain lasts more than 5 days, you need a different pain management strategy. Do not combine ketorolac with other NSAIDs such as ibuprofen, naproxen, or aspirin used for pain, because the risks add up. If you take low-dose aspirin for heart protection, ketorolac can interfere with its effect. Always tell your doctor about all your medications before starting. Because of the bleeding risk, ketorolac is contraindicated before major surgery, in patients with active bleeding, or in those with a history of stomach ulcers. It is also not used in people with severe kidney disease.

Side Effects of Ketorolac

The side effects are the same class effects as other NSAIDs, but amplified. The most common are gastrointestinal: stomach pain, nausea, indigestion, and diarrhea. Taking the tablet with food reduces these. The most dangerous is gastrointestinal bleeding. Ketorolac can cause stomach ulcers, perforation, and bleeding, which can be fatal. This risk is present even with short courses and is higher in the elderly, at higher doses, and in patients taking corticosteroids or anticoagulants. Signs of a bleeding ulcer include black, tarry stools, vomiting blood, or severe abdominal pain. If these occur, stop the drug immediately and seek emergency care.

Kidney damage is a major concern. Ketorolac reduces blood flow to the kidneys, which can cause acute kidney injury, especially in dehydrated patients, those with heart failure, or those taking diuretics or ACE inhibitors. Fluid retention and swelling can occur. Allergic reactions range from rash to anaphylaxis with swelling of the face and throat. Ketorolac can raise blood pressure and increase the risk of heart attack and stroke, like all NSAIDs. It also inhibits platelet function, leading to prolonged bleeding time, which is dangerous after surgery or injury. Dizziness and drowsiness are possible. Ketorolac is not a safe drug for everyone. Its potency is real, but so is its danger.

High-Risk Groups (Elderly, Pregnancy)

Pregnancy. Ketorolac is pregnancy category C in the first and second trimesters and category D in the third trimester. It is contraindicated in the third trimester because it can cause premature closure of the ductus arteriosus in the fetus and may delay labour. It is also contraindicated during labour and delivery because of the bleeding risk. Ketorolac should be avoided throughout pregnancy if possible. Acetaminophen is the preferred pain reliever. Breastfeeding. Ketorolac passes into breast milk in small amounts. The manufacturer recommends against its use during breastfeeding because of the potential for adverse effects on the infant, including bleeding and kidney problems. Occasional use of a single dose may be acceptable, but regular use is not. Discuss with your doctor.

Elderly patients are at significantly higher risk of stomach ulcers, bleeding, kidney failure, and heart failure from ketorolac. The dose should be reduced, and the drug should be used for the shortest possible time, if at all. Many clinicians avoid ketorolac entirely in patients over 65. People with a history of stomach ulcers, bleeding disorders, inflammatory bowel disease, or those taking anticoagulants should not use ketorolac. Severe kidney disease, severe heart failure, and active liver disease are contraindications. Dehydration, even mild, increases the risk of kidney damage. A complete medication review is absolutely essential before starting.

Interaction With Activities (Driving, Alcohol)

Ketorolac can cause dizziness, drowsiness, and blurred vision. If you experience these, do not drive or operate machinery. The effects are more likely than with weaker NSAIDs. Alcohol significantly increases the risk of stomach bleeding and irritation when combined with ketorolac. It also adds to dizziness and can worsen kidney injury. Avoid alcohol entirely while taking this drug. Even a single drink can trigger gastric bleeding in a susceptible person. If you drink, do not take ketorolac. The combination of ketorolac and alcohol on an empty stomach is a serious risk.

Drug Interactions

Ketorolac has the same interactions as other NSAIDs, but because it is so potent, the consequences are more severe. Anticoagulants like warfarin, clopidogrel, and the direct oral anticoagulants (apixaban, rivaroxaban) greatly increase the risk of bleeding and are generally contraindicated with ketorolac. Aspirin, even low-dose, increases the risk of stomach ulcers and bleeding. Corticosteroids increase the risk of ulcers. SSRIs and SNRIs, used for depression, also increase bleeding risk. Methotrexate, lithium, and cyclosporine levels can rise, leading to toxicity. ACE inhibitors, ARBs, and diuretics can become less effective and the combination can precipitate kidney failure. Probenecid, used for gout, slows the excretion of ketorolac and increases its levels. The combination should be avoided. Always provide your doctor and pharmacist with a complete list of your medications before taking ketorolac.

Alternative Options

For moderate to severe pain, alternatives depend on the cause and the patient's risk factors. Acetaminophen is safer for the stomach and kidneys but less effective for inflammation. Ibuprofen and naproxen are weaker NSAIDs that can be used for longer periods and with less immediate danger, though they share the same class risks. Celecoxib is a COX-2 selective NSAID with a lower risk of stomach ulcers but a higher cardiovascular risk. For severe pain, opioids are sometimes used, but they carry addiction and sedation risks. Combination therapy, such as acetaminophen with a weak opioid, is often used after surgery. Topical NSAIDs or lidocaine patches can provide localized relief without systemic exposure. The choice depends on the severity of pain, the expected duration, and the patient's kidney, stomach, and heart health. Ketorolac is reserved for short, intense pain episodes where its potency justifies its risk profile.

Frequently Asked Questions

Why can I only take ketorolac for 5 days?
The risk of stomach ulcers, bleeding, and kidney damage rises sharply after 5 days. This is not a maintenance drug. It is for short-term, severe pain only. If you need pain relief beyond 5 days, your doctor should switch you to a safer long-term option.

Can I take ketorolac for a headache?
No. Ketorolac is too strong and too dangerous for a simple headache. Use acetaminophen or ibuprofen instead. Ketorolac is for significant pain after surgery or injury, not everyday aches.

Is ketorolac stronger than morphine?
In some post-surgical settings, 30 mg of ketorolac by injection is comparable to 10 mg of morphine for pain relief, but without the sedation. The oral 10 mg tablet is less studied but still potent. It is not a narcotic and does not cause addiction, but it has its own serious risks.

Can I take ketorolac if I have kidney problems?
You should not. Ketorolac can cause acute kidney failure, especially in anyone with pre-existing kidney disease, dehydration, or heart failure. If you have any kidney issues, tell your doctor before taking this drug.

What should I do if I vomit after taking ketorolac?
If you vomit within 30 minutes of taking the tablet, it may not have been absorbed. Contact your doctor or pharmacist for advice. Do not automatically take another dose, as this can lead to overdose. If you vomit after more than an hour, the drug has likely been absorbed.
