Toradol: Potent Non-Opioid Pain Relief for Acute Conditions
Toradol (ketorolac tromethamine) is a nonsteroidal anti-inflammatory drug (NSAID) indicated for the short-term management of moderately severe acute pain that requires analgesia at the opioid level. As a potent analgesic with anti-inflammatory and antipyretic properties, it offers a critical therapeutic option for clinicians seeking effective pain control while mitigating the risks associated with opioid medications, such as respiratory depression and the potential for dependence. Its unique pharmacologic profile allows for use in both injectable and oral formulations, facilitating a step-down approach in pain management protocols across various clinical settings, from post-operative care to emergency department use.
Features
- Active pharmaceutical ingredient: Ketorolac tromethamine.
- Available in multiple formulations: intramuscular (IM) and intravenous (IV) injection, and oral tablets.
- Classified as a nonsteroidal anti-inflammatory drug (NSAID) of the acetic acid derivative class.
- Possesses potent analgesic, anti-inflammatory, and antipyretic (fever-reducing) properties.
- Onset of analgesic action is rapid, typically within 10 minutes for IV administration and 30 minutes for IM administration.
- Peak plasma concentrations are reached within approximately 30-60 minutes following intramuscular injection.
- Demonstrated analgesic efficacy comparable to certain opioid medications like morphine or meperidine in acute pain settings.
- Not classified as a controlled substance, eliminating concerns regarding narcotic scheduling and associated prescribing restrictions.
Benefits
- Provides powerful, opioid-level analgesia without the associated risks of respiratory depression, significant sedation, or physical dependence.
- Effectively reduces inflammation at the site of injury or surgical intervention, addressing a key component of pain pathophysiology.
- Facilitates a multimodal analgesic approach, potentially reducing the total dosage of concomitant opioids required for adequate pain control (opioid-sparing effect).
- Offers flexible administration routes (IV, IM, oral) allowing for seamless transition from inpatient to outpatient care.
- Rapid onset of action ensures prompt relief for patients experiencing acute, moderate to severe pain.
- Can be a valuable tool in protocols designed to combat the opioid epidemic by providing a potent non-opioid alternative.
Common use
Toradol is specifically indicated for the short-term (up to 5 days) management of moderately severe acute pain. Its use is typically reserved for situations where an analgesic with potency comparable to opioids is warranted, but the risks of opioid therapy are undesirable or must be minimized. Common clinical applications include:
- Post-operative pain management following a wide range of surgical procedures (e.g., orthopedic, abdominal, gynecological).
- Pain associated with acute musculoskeletal injuries, such as fractures, sprains, and strains.
- Renal colic (pain from kidney stones).
- Acute migraine attacks (often used in combination with other anti-migraine agents in emergency settings).
- Providing analgesia in emergency department settings for various painful conditions. It is crucial to note that Toradol is not indicated for minor or chronic pain conditions, nor is it intended for prophylactic use or as an antipyretic.
Dosage and direction
Dosing of Toradol is highly dependent on the patient’s age, renal function, route of administration, and the specific formulation used. The following represents general guidelines; always adhere to the specific prescribing information and institutional protocols.
- Adults (under 65 years, with normal renal function):
- Single-Dose Treatment (IM/IV): 60 mg as a single dose, or 30 mg for patients with a lower body weight or those at increased risk for adverse effects.
- Multiple-Dose Treatment (IM/IV): 30 mg every 6 hours. The maximum daily dose should not exceed 120 mg.
- Oral Tablets (as continuation from parenteral therapy): 20 mg as a first dose for patients who received a single 60 mg IM/IV dose or a 30 mg IM/IV dose, followed by 10 mg every 4 to 6 hours. The maximum daily oral dose is 40 mg.
- Geriatric Patients (65 years and older), patients with renal impairment, or low body weight (<50 kg):
- Dosing must be reduced. A typical multiple-dose regimen is 15 mg IM/IV every 6 hours, with a maximum daily dose of 60 mg.
- Corresponding oral dosing is reduced to 10 mg every 4 to 6 hours, not to exceed 40 mg daily.
- Duration of Therapy:
- The total duration of Toradol therapy (combined parenteral and oral) must not exceed 5 days due to the significantly increased risk of serious adverse events with longer use.
- Administration:
- Parenteral formulations are for intramuscular or intravenous use only.
- Oral tablets should be taken with a full glass of water and may be taken with food or an antacid to minimize gastrointestinal upset.
Precautions
Administration of Toradol requires careful patient assessment and vigilant monitoring due to its significant risk profile.
- Gastrointestinal (GI) Risk: Toradol poses a high risk of causing serious GI adverse events, including bleeding, ulceration, and perforation, which can be fatal. These events can occur at any time, with or without warning symptoms, during therapy.
- Renal Effects: Use with extreme caution in patients with pre-existing renal impairment, volume depletion, heart failure, liver dysfunction, or those taking diuretics or ACE inhibitors. Toradol can cause renal papillary necrosis and other renal injury, which may lead to acute renal failure.
- Cardiovascular Thrombotic Risk: NSAIDs, including Toradol, increase the risk of serious and sometimes fatal cardiovascular thrombotic events, such as myocardial infarction and stroke.
- Hematologic Effects: May inhibit platelet aggregation and prolong bleeding time. Use with caution in patients with underlying coagulopathies or those undergoing surgical procedures with a high risk of bleeding.
- Hepatic Effects: Borderline elevations of liver function tests may occur in up to 15% of patients. Severe hepatic reactions, including jaundice and fatal hepatitis, can occur.
- Monitoring: Clinicians should monitor renal function, hemoglobin, and signs of GI bleeding during treatment, especially in high-risk patients.
Contraindications
Toradol is contraindicated in the following scenarios:
- Known hypersensitivity (e.g., anaphylactic reactions, serious skin reactions) to ketorolac tromethamine, any component of the formulation, or other NSAIDs.
- Patients with a history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions have been reported.
- In the setting of peri-operative pain in the context of coronary artery bypass graft (CABG) surgery.
- Patients with active peptic ulcer disease, recent gastrointestinal bleeding or perforation, or a history of peptic ulcer disease or GI bleeding.
- Patients with advanced renal impairment or patients at risk for renal failure due to volume depletion.
- As a prophylactic analgesic before any major surgery.
- In combination with other NSAIDs, including aspirin, or with probenecid or pentoxifylline.
- During labor and delivery, and in nursing mothers.
- For neuraxial (epidural/intrathecal) administration due to its alcohol content.
Possible side effect
The use of Toradol can be associated with a wide range of adverse reactions. The most common (≥2%) side effects involve the gastrointestinal and central nervous systems.
- Gastrointestinal: Dyspepsia, nausea, vomiting, abdominal pain, constipation, diarrhea, flatulence, GI fullness, stomatitis, gastritis.
- Central Nervous System: Headache, dizziness, drowsiness, sweating.
- Other: Edema (fluid retention), hypertension, purpura, injection site pain (with IM formulation).
- Serious Side Effects (seek immediate medical attention):
- Signs of GI bleeding or ulceration (e.g., hematemesis, melena, hematochezia).
- Signs of hepatotoxicity (e.g., nausea, fatigue, lethargy, jaundice, right upper quadrant tenderness).
- Signs of heart failure or hypertension (e.g., shortness of breath, unexplained weight gain, edema).
- Signs of renal impairment (e.g., changes in urine output, swelling).
- Signs of an allergic reaction (e.g., skin rash, blisters, fever, itching, difficulty breathing, swelling of face/throat).
- Signs of aseptic meningitis (e.g., stiff neck, fever).
- Signs of a cardiovascular event (e.g., chest pain, shortness of breath, weakness, slurred speech).
Drug interaction
Toradol has the potential for significant and dangerous interactions with numerous medications.
- Other NSAIDs and Aspirin: Concomitant use is contraindicated due to additive risks of serious GI toxicity.
- Anticoagulants (e.g., Warfarin) and Antiplatelets (e.g., Clopidogrel): Increased risk of serious bleeding due to additive effects on platelet function and potential ulcerogenic effects.
- ACE Inhibitors, ARBs, and Diuretics: Toradol may reduce the antihypertensive and natriuretic effect of these agents, potentially leading to acute renal failure, particularly in volume-depleted patients.
- Lithium: Toradol can decrease renal clearance of lithium, leading to increased plasma lithium levels and potential lithium toxicity.
- Methotrexate: Toradol can reduce the tubular secretion of methotrexate, potentially increasing methotrexate plasma levels and its associated toxicity.
- Selective Serotonin Reuptake Inhibitors (SSRIs): Concomitant use increases the risk of GI bleeding.
- Probenecid: Concomitant use is contraindicated as it significantly increases ketorolac plasma levels and half-life.
- Pentoxifylline: Concomitant use is contraindicated due to an increased risk of bleeding.
- Pemetrexed: Should be avoided for several days before, during, and after pemetrexed administration in patients with renal impairment.
Missed dose
Given that Toradol is prescribed for short-term, as-needed analgesia on a fixed schedule for a maximum of 5 days, the concept of a “missed dose” is less defined than with chronic medications.
- If a dose is missed, it should be taken as soon as it is remembered.
- However, if it is almost time for the next scheduled dose, the missed dose should be skipped.
- The patient should never take a double dose to make up for a missed one.
- Patients should be instructed to maintain the prescribed interval between doses (e.g., every 6 hours) and not to exceed the maximum daily dosage under any circumstances.
Overdose
Overdose of Toradol can be serious and potentially fatal. Symptoms are generally extensions of its common adverse effects.
- Symptoms: May include abdominal pain, nausea, vomiting, lethargy, drowsiness. More severe symptoms can include respiratory depression, coma, renal failure, gastrointestinal bleeding, hypertension, or acute renal failure. Anaphylactic reactions may occur.
- Management: There is no specific antidote for ketorolac overdose. Management is supportive and symptomatic.
- Employ gastric lavage or administer activated charcoal (if ingestion was recent) to reduce absorption.
- Provide supportive care, including maintaining a patent airway and monitoring cardiac status and vital signs.
- Forced diuresis, alkalization of the urine, hemodialysis, or hemoperfusion are unlikely to be beneficial due to Toradol’s high protein binding and extensive metabolism.
- Contact a poison control center for the most current guidance.
Storage
- Store at controlled room temperature, 20°C to 25°C (68°F to 77°F).
- Protect from light.
- Keep the medication in its original container, tightly closed, and out of reach of children and pets.
- Do not store in bathrooms or other damp places. Heat and moisture may degrade the medication.
- Do not freeze the injectable solution.
- Properly discard any unused medication after the course of therapy is complete or after the expiration date has passed.

Reviews
- “As an anesthesiologist, Toradol is an indispensable part of our multimodal analgesia protocol for post-operative patients. Its opioid-sparing effect is significant, allowing for better pain control with fewer opioid-related side effects like nausea and ileus. The strict 5-day limit is a critical safety rule we never violate.” – Dr. A., MD, Anesthesiology
- “In the emergency department, IV Toradol is a first-line agent for renal colic and acute musculoskeletal pain. It works rapidly and effectively. However, its use requires careful patient selection; we rigorously screen for any history of renal impairment, GI issues, or bleeding risk before administration.” – Physician Assistant, Emergency Medicine
- “The transition from IV to oral Toradol provides a seamless continuum of care for our orthopedic surgery patients upon discharge. It helps manage their pain effectively during the most acute phase at home. Patient education on the short duration and potential stomach side effects is paramount.” – Orthopedic Nurse Practitioner
- “While potent, the side effect profile of ketorolac demands immense respect. I have seen cases of acute GI bleeding precipitated by its use, even with short courses. It is a powerful tool, but it must be used with extreme caution and only in the appropriate patient population.” – Clinical Pharmacist
