It works by reducing inflammation and blocking pain signals in the body.
The generic version is a cost-effective alternative to brand-name drugs with the same active ingredient and effectiveness.
Ketorolac should be used for the shortest time possible due to serious side effect risks.
Always discuss your full medical history and current medications with your healthcare provider before taking ketorolac.
Toradol (Generic Ketorolac Tromethamine) Overview
Ketorolac tromethamine, commonly known by its brand name Toradol, is a nonsteroidal anti-inflammatory drug (NSAID) that provides strong pain relief and reduces inflammation. It belongs to a class of medications designed for short-term management of moderate to severe acute pain, most often following surgery or injury. Unlike other pain relievers, ketorolac works by blocking the production of prostaglandins—chemical messengers in your body that cause pain and inflammation.
This medication is typically prescribed for no longer than five days because prolonged use increases the risk of serious side effects. Ketorolac is available in multiple forms including tablets, injections, and nasal spray, making it versatile for different medical situations. The generic version contains the same active ingredient as the brand-name Toradol and is equally effective, making it a practical choice for patients seeking affordable pain management.
When you need short-term pain relief, understanding your medication options—including the difference between generic vs brand-name drugs—helps you make informed decisions about your treatment. Ketorolac is particularly useful in hospital and clinical settings but must be used carefully and under medical supervision.
Side Effects
Ketorolac is generally well-tolerated when used for short periods, but like all medications, it can cause side effects. Most people experience mild reactions, while serious ones are less common but require immediate attention.
Common Side Effects
Indigestion or heartburn – Ketorolac can irritate your stomach lining, causing uncomfortable burning sensations or acid reflux, especially if taken without food.
Nausea – Feeling sick to your stomach is a frequent reaction, though it usually improves as your body adjusts to the medication.
Dizziness or headache – Some people experience lightheadedness or mild headaches, which typically subside with continued use.
Drowsiness – Ketorolac may make you feel tired or less alert, so avoid driving or operating machinery until you know how it affects you.
Fluid retention – The medication can cause your body to retain water, leading to mild swelling in your hands, feet, or legs.
Serious Side Effects
Gastrointestinal bleeding – Ketorolac can cause bleeding in your stomach or intestines, which may result in black, tarry stools or vomiting blood.
Severe allergic reactions – Though rare, some people experience hives, difficulty breathing, or swelling of the face and throat after taking ketorolac.
Kidney problems – Prolonged use or use in people with existing kidney issues may cause kidney damage or reduced kidney function.
High blood pressure or heart problems – Ketorolac can increase blood pressure and raises the risk of heart attack or stroke, especially in people with existing cardiovascular disease.
Liver damage – In rare cases, ketorolac may cause liver function abnormalities or hepatotoxicity.
When to Seek Medical Attention
Contact your healthcare provider immediately if you experience severe stomach pain, vomiting blood, black or tarry stools, shortness of breath, chest pain, severe allergic reactions, or signs of kidney problems like reduced urine output. Do not wait if you have signs of bleeding or severe allergic reactions—seek emergency care right away. For less severe side effects like mild nausea or headache, call your doctor to discuss whether continuing the medication is appropriate or if adjustments are needed.

Always take ketorolac with food or milk to minimize stomach irritation, and stay well-hydrated while using this medication.
Drug Interactions
Ketorolac interacts with several medications and substances, potentially reducing their effectiveness or increasing your risk of side effects. Always inform your healthcare provider about all medications and supplements you take before starting ketorolac.
Blood Thinners (Warfarin, Dabigatran)
Ketorolac increases your bleeding risk when combined with blood thinners. Taking both medications together may lead to excessive bruising, bleeding, or life-threatening hemorrhage.
ACE Inhibitors and ARBs (Blood Pressure Medications)
Ketorolac may reduce the effectiveness of blood pressure medications like lisinopril or losartan and can increase your risk of kidney problems when used together.
Lithium (Mood Stabilizer)
Ketorolac can increase lithium levels in your blood, potentially causing toxicity. Regular blood tests may be needed if both medications are necessary.
Diuretics (Water Pills)
Combining ketorolac with diuretics like furosemide may reduce the diuretic's effectiveness and increase your risk of kidney damage and electrolyte imbalances.
Other NSAIDs (Ibuprofen, Naproxen)
Never take ketorolac with other NSAIDs, as this significantly increases your risk of serious gastrointestinal bleeding and kidney problems.
Methotrexate (Cancer and Immune-Suppressant Drug)
Ketorolac may increase methotrexate levels, raising the risk of toxic side effects on your bone marrow and kidneys.

Frequently Asked Questions
Get answers to common questions about ketorolac tromethamine.
Ketorolac typically begins working within 30 minutes to one hour when taken orally, and even faster—within 10 to 15 minutes—when given as an injection. The fast-acting nature of this medication is one reason it's popular for acute post-surgical or post-injury pain. However, the full effect may take up to two hours, so plan accordingly for pain relief timing.
Yes, and you should. Taking ketorolac with food, milk, or a glass of water helps reduce stomach irritation and indigestion. Food does not significantly delay absorption or reduce effectiveness, so eating with your dose is actually recommended to protect your digestive system from potential irritation or ulceration.
If you miss a dose of ketorolac, take it as soon as you remember. However, if your next scheduled dose is approaching—within a few hours—skip the missed dose and continue with your regular schedule. Never double up on doses to make up for a missed one, as this increases your risk of side effects and overdose.
No, ketorolac is specifically designed for short-term use only and should not be taken for more than five days. Long-term use significantly increases your risk of serious gastrointestinal bleeding, kidney damage, and cardiovascular problems. If you have chronic pain, discuss other treatment options like whiplash causes, symptoms, diagnosis, and treatment management plans with your healthcare provider.
Ketorolac may cause drowsiness or dizziness in some people, so avoid driving, operating machinery, or performing other dangerous activities until you know how the medication affects you. If you experience significant drowsiness or dizziness, do not drive and contact your doctor to discuss whether continuing the medication is safe or if dosage adjustments are needed.
The Bottom Line
Ketorolac tromethamine is a powerful short-term pain reliever that works quickly and effectively for acute moderate to severe pain, especially after surgery or injury. Its strength comes with important responsibilities—it must be used for five days or fewer and requires careful consideration of your medical history and current medications. While the generic version offers the same effectiveness as brand-name Toradol at a lower cost, making it a practical choice, serious side effects like gastrointestinal bleeding and kidney problems are possible. This medication works best under medical supervision and in combination with lifestyle measures like rest and ice therapy. Understanding both the benefits and risks helps you use ketorolac safely and effectively.
