At Hope Harbor Wellness in Atlanta, GA, we meet many people who need short-term relief from serious pain and want clear, reliable information about their options. Ketorolac, often known by the brand Toradol, is a powerful non-steroidal anti-inflammatory drug (NSAID) that can help with moderate to severe pain when used for a very limited time. It’s sometimes chosen instead of an opioid in hospitals and clinics. Still, it carries important risks.
This expanded guide explains what ketorolac is, how it’s used, who should avoid it, and the side effects and interactions you need to know. We’ll also cover practical dosing guidance your provider might use, what to do about adverse reactions, and how ketorolac compares with other pain relievers. As an outpatient drug rehab in Atlanta where we offer mental health services, addiction treatment, and drug detox, our role is to offer balanced, safety-first guidance—especially when pain and substance use risks intersect.
Article at a Glance
- Ketorolac (Toradol) is one of the most potent NSAIDs. It’s intended for short-term use only and is often started by injection in medical settings, then continued briefly as tablets or a nasal spray.
- Limit use to five days total. Longer courses sharply increase risks for gastrointestinal bleeding, kidney injury, and cardiovascular events.
- Toradol side effects can be serious. Watch for stomach pain, black stools, chest pain, shortness of breath, weakness on one side, confusion, swelling, or decreased urination.
- People with certain conditions should avoid ketorolac. This includes active GI ulcers or bleeding, significant kidney disease, certain heart conditions, and late pregnancy or labor.
- Never combine with other NSAIDs or aspirin for pain. Dangerous bleeding can result. Many prescriptions and OTC products contain hidden NSAIDs—double-check labels.
- Talk with your prescriber about interactions. Blood thinners, blood pressure medicines, lithium, methotrexate, and some seizure or psychiatric meds may interact.
- Ketorolac is not addictive, but misuse can harm your heart, stomach, and kidneys. It is not a substitute for comprehensive pain or addiction care.
What Is Toradol?
Toradol is a former U.S. brand name for ketorolac tromethamine, a prescription-only NSAID used to treat moderate to severe acute pain for the shortest possible time. In U.S. pharmacies today, ketorolac is mostly dispensed as a generic. A nasal spray formulation is available under the brand Sprix. Ketorolac injection is commonly used in hospitals for an initial dose, followed by a brief oral or intranasal course at home if appropriate.
Ketorolac also exists as ophthalmic drops (e.g., Acular, Acuvail) to manage eye pain and inflammation after eye surgery. Those drops act locally and are different from the systemic forms discussed here.
Why providers use it: ketorolac can reduce pain enough to avoid or reduce opioid exposure after certain procedures. That’s helpful, but only when the risk–benefit balance is favorable and the 5-day limit is respected.
Warnings and Pre-Existing Conditions
Ketorolac is not a casual pain reliever. It has black box warnings and strict duration limits. Your medical history matters.
Situations where ketorolac is usually avoided or used only with extreme caution:
- Active or recent GI issues: peptic ulcer disease, GI bleeding, or perforation. Ketorolac further irritates the stomach and intestines and can trigger dangerous bleeding.
- Cardiovascular disease: history of heart attack, stroke, uncontrolled hypertension, or heart failure. All NSAIDs (except low-dose aspirin for cardioprotection) can raise the risk of heart attack and stroke, sometimes without warning.
- Kidney disease or dehydration: ketorolac can reduce kidney blood flow, leading to acute kidney injury—especially in older adults, people on diuretics, ACE inhibitors/ARBs, or those who are dehydrated.
- Upcoming or recent surgery: increased bleeding risk is a concern. Your surgeon and anesthesiologist should approve any perioperative NSAID plan.
- Labor and delivery: ketorolac can reduce uterine contractions and affect fetal circulation; it’s contraindicated in labor. (Breastfeeding use may be considered in limited cases—defer to your OB.)
- Bleeding disorders or anticoagulation therapy: risk of bleeding increases.
- Older age (especially 75+): higher risk of GI, kidney, and cardiovascular side effects.
- Allergies to NSAIDs or aspirin: avoid due to risk of severe reactions (including bronchospasm in aspirin-sensitive asthma).
If any of the above apply, your provider may choose a different pain strategy or add protective measures (e.g., GI protection with a PPI, extra lab monitoring). Never start or extend ketorolac without medical supervision.
Toradol (Ketorolac): Interactions and What To Avoid
Interactions can be dangerous. Share every medication and supplement you take, including OTC products and herbals.
Avoid these with ketorolac unless your prescriber explicitly recommends otherwise:
- Aspirin or other NSAIDs for pain (ibuprofen, naproxen, diclofenac). Combining NSAIDs compounds bleeding and kidney risks.
- Probenecid (gout medicine): raises ketorolac levels and toxicity risk.
- Pentoxifylline (improves blood flow): increases bleeding risk.
Use extra caution and monitoring with:
- ACE inhibitors and ARBs (lisinopril, enalapril, losartan, valsartan): combined use can strain the kidneys and raise potassium.
- Diuretics (furosemide, hydrochlorothiazide): higher chance of dehydration and kidney issues.
- Lithium: ketorolac may increase lithium levels, risking toxicity (tremor, confusion, GI upset).
- Methotrexate and pemetrexed: potential for higher toxicity; blood counts and kidney function may need monitoring.
- Cyclosporine: additive kidney stress.
- Digoxin: possible increase in digoxin levels—monitor.
- Anticoagulants and antiplatelets (warfarin, DOACs, clopidogrel): major bleeding risk increases.
- Antidepressants, benzodiazepines, muscle relaxants: may worsen sedation, dizziness, or falls, especially in older adults.
- Alcohol: raises GI bleed risk and can worsen dizziness or sedation.
Bottom line: do not mix ketorolac with other NSAIDs or aspirin for pain relief, and do not stop any chronic medication without your prescriber’s guidance.
Dosage and How to Take
Ketorolac is potent and intended for short-term use. Many courses begin with an injection in the hospital or clinic, followed by oral tablets or nasal spray at home. The total duration of therapy from first dose to last must not exceed 5 days.
Typical adult dosing your provider may use:
- Oral tablets: 20 mg once, then 10 mg every 4–6 hours as needed, not to exceed 40 mg in 24 hours.
- If body weight is under 110 lb (50 kg) or if you are older or frail, the initial dose is often 10 mg, with longer intervals.
- Nasal spray (Sprix): one spray in each nostril every 6–8 hours as needed, up to four doses in 24 hours.
- If under 110 lb (50 kg), many prescribers reduce to one spray in one nostril per dose.
- With food? Not required, but taking with food or milk can reduce stomach upset.
- Hydration: Stay well hydrated unless you’re on a fluid restriction; dehydration increases kidney risk.
Do not exceed the dose or duration. If pain is still severe at day five, contact your healthcare team to reassess the plan rather than continuing ketorolac.
Toradol Side Effects: What to Watch For
Common, often temporary effects can occur, especially at the start of therapy. Report persistent or severe symptoms.
Common with oral tablets:
- Headache, dizziness, or drowsiness
- Stomach upset, nausea, or diarrhea
- Indigestion or abdominal pain
- Peripheral swelling (hands, feet)
Common with nasal spray:
- Burning or nasal discomfort, stuffy or runny nose
- Throat irritation, watery eyes
- Headache or dizziness
- Less commonly: reduced urination, skin rash, slow heartbeat, elevated blood pressure
Serious but less common effects (<1% reported):
- GI bleeding (black/tarry stools, vomiting blood, severe stomach pain)
- Heart problems (chest pain, shortness of breath, sudden weakness on one side, speech difficulty)
- Kidney issues (little or no urine, swelling, fatigue)
- Allergic reactions (lip/tongue/face swelling, hives, wheezing)
- Severe skin reactions (blistering rash)
- Pancreatitis, inflammatory bowel flares, mood changes, light sensitivity
Act now if any red flags appear. Call 911 for chest pain, stroke symptoms, severe breathing trouble, or signs of major bleeding. For concerning but non-emergent effects, contact your prescriber the same day—do not “push through” side effects with ketorolac.
Ketorolac Overdose
A ketorolac overdose may not look dramatic at first, but it can be dangerous.
Possible consequences of too much ketorolac:
- Kidney injury (reduced urination, swelling, rising creatinine)
- Liver stress (abdominal pain, dark urine, jaundice)
- Serious skin reactions
- Lithium toxicity if you also take lithium (tremor, confusion, vomiting)
If you suspect an overdose or took extra doses by mistake, seek medical attention immediately. Bring the bottle or nasal spray and a list of all medicines and supplements you took.
Toradol (Ketorolac): Potential for Abuse
Ketorolac is not a controlled substance and not considered addictive. No typical “euphoria” or reinforcement occurs the way it can with opioids or certain sedatives. However, there’s still a misuse risk if someone self-extends treatment or combines it with other NSAIDs to try to control pain—behavior that raises the chance of GI bleeds, kidney damage, and cardiovascular events.
If chronic pain or mental health symptoms are driving you toward unsafe medication patterns—or toward alcohol or opioids for relief—comprehensive, integrated care can help. At Hope Harbor Wellness, we address pain, mood, and substance use together so you don’t have to choose between suffering and unsafe shortcuts.
How long does Toradol last and how does it work?
- Onset: After an injection, pain relief can begin within 30–60 minutes. Oral and intranasal forms may take a bit longer.
- Duration: Many people feel relief for 4–6 hours per dose.
How it works: Like other NSAIDs, ketorolac blocks cyclooxygenase (COX-1 and COX-2) enzymes that drive prostaglandin production. Fewer prostaglandins means less inflammation and pain—but also reduced protective mucus and blood flow in the GI tract and kidneys. That’s why bleeding and kidney risks rise at higher doses and longer durations.
Key takeaway: Ketorolac is designed for short bursts of strong anti-inflammatory action, not daily long-term use. Respecting the 5-day cap protects your stomach, kidneys, and heart.
Toradol vs. Ibuprofen and Naproxen: Which is safer?
All NSAIDs share similar classes of risks. What differs is potency and how we use them.
- Ketorolac (Toradol): very potent, reserved for short-term moderate to severe pain, often post-procedure. Strict 5-day maximum.
- Ibuprofen: over-the-counter at lower doses; can help with mild to moderate pain and fever. Still carries GI, kidney, and heart risks—especially at high doses or long durations.
- Naproxen: longer-acting; sometimes preferred when cardiovascular risk is a concern, but GI and kidney cautions remain.
When might ketorolac be chosen? When you need strong, opioid-sparing pain relief for a brief window. When might ibuprofen or naproxen be safer? For milder pain or when you need an OTC option with flexibility—provided you follow dosing limits and your provider says it’s appropriate.
Never combine ketorolac with ibuprofen or naproxen for extra relief. That strategy increases harm without meaningful benefit.
Toradol and Alcohol, Driving, and Work Safety
- Alcohol: Even small amounts can raise GI bleeding risk and worsen dizziness or drowsiness. The safest choice is to avoid alcohol while taking ketorolac.
- Driving and machinery: Until you know how you react, don’t drive or operate machinery. Dizziness and slowed reaction time can occur.
- Physically demanding work: Heavy lifting, climbing, or heat exposure can worsen dehydration and strain the kidneys. Stay hydrated, plan rest breaks, and report any dizziness or weakness to your supervisor and provider.
Toradol in Special Populations: Pregnancy, Breastfeeding, and Older Adults
- Pregnancy: Ketorolac is contraindicated in labor and generally avoided in late pregnancy due to fetal circulation and uterine effects. Use earlier in pregnancy is typically discouraged unless benefits clearly outweigh risks. Always consult your OB.
- Breastfeeding: Limited data suggest low levels in milk after occasional dosing, but decisions are individualized. Discuss timing and alternatives with your pediatrician/OB.
- Older adults (75+): Higher rates of GI, kidney, and cardiovascular side effects. If used, lower doses, shorter duration, and closer monitoring are standard.

Toradol (Ketorolac) FAQs
What do you need to know before taking Toradol?
Ketorolac is a prescription-strength NSAID meant for no more than five days total. It can raise the risk of stomach and intestinal bleeding, heart attack or stroke, and kidney injury, especially if you have a history of GI disease, heart disease, or kidney problems. Never combine it with other NSAIDs or aspirin for pain relief, and tell your provider about all medicines and supplements.
How long does Toradol stay in your system?
In most adults, ketorolac’s half-life is about 6 hours. It takes roughly five half-lives to clear a dose, so around 30 hours for most people. In older adults, the half-life can be closer to 7 hours (≈35 hours to clear). In kidney impairment, the half-life can be ~13.6 hours (≈68 hours to clear). Because of these differences, spacing doses and respecting the 5-day cap are essential.
How long after Toradol can you take ibuprofen?
Do not layer NSAIDs. Because ketorolac remains active for many hours and increases bleeding risk, you should avoid ibuprofen until your prescriber confirms it’s safe for your situation and enough time has passed. Many people need to wait at least a full day or more, but the exact timing depends on your health, dose, and form used. Ask your provider.
How is Toradol most commonly prescribed?
In the U.S., oral tablets are commonly used after an initial injection in a medical setting. The nasal spray is another option for short-term use. In 2020, more than a million Americans received a ketorolac prescription, typically for brief post-procedure or acute injury pain.
Is Toradol an opioid?
No. Ketorolac is an NSAID, not an opioid. It reduces inflammation and pain without producing opioid-type euphoria. That said, it still carries serious risks if misused or used too long.
Can I drink alcohol on Toradol?
It’s best to avoid alcohol while taking ketorolac. Alcohol increases the chance of stomach bleeding and can worsen dizziness or drowsiness.
What should I do if I miss a dose?
If you’re on a scheduled short course, take the next dose only if needed and never double up. Because ketorolac is for as-needed short-term use, keeping doses as low and few as possible reduces risks. If pain isn’t controlled, contact your provider rather than increasing doses on your own.
