Indications and Usage
SPRIX® (ketorolac tromethamine) is indicated in adult patients for the short term (up to 5 days) management of moderate to moderately severe pain that requires analgesia at the opioid level.
Warnings and Precautions
Cardiovascular Thrombotic Events: increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Contraindicated in the setting of CABG. Patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment.
Gastrointestinal Bleeding, Ulceration, and Perforation: contraindicated in patients with active peptic ulcers and/or GI bleeding and in patients with recent gastrointestinal bleeding or perforation. Can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms. Patients with a prior history of peptic ulcer disease and/or GI bleeding who used NSAIDs had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors.
Hepatotoxicity: Inform patients of warning signs and symptoms of hepatotoxicity. Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop.
Hypertension: NSAIDs, including SPRIX, can lead to new onset or worsening of preexisting hypertension. Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs. Monitor blood pressure.
Heart Failure and Edema: Avoid use of SPRIX in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure.
Renal Toxicity and Hyperkalemia: Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of SPRIX in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function.
Anaphylactic Reactions: Seek emergency help if an anaphylactic reaction occurs.
Exacerbation of Asthma Related to Aspirin Sensitivity: Contraindicated in patients with aspirin-sensitive asthma. Monitor patients with preexisting asthma (without known aspirin sensitivity).
Serious Skin Reactions: NSAIDs, including SPRIX, can cause serious skin reactions, which can be fatal. Discontinue SPRIX at first appearance of skin rash or other signs of hypersensitivity.
Premature Closure of Fetal Ductus Arteriosus: Avoid use in pregnant women starting at 30 weeks gestation.
Hematologic Toxicity: Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia. Do not use SPRIX in patients for whom hemostasis is critical.
Limitations of Use: SPRIX should not be used concomitantly with IM/IV or oral ketorolac, aspirin, or other NSAIDs.
Serious adverse reactions include: cardiovascular thrombotic events; GI bleeding, ulceration and perforation; hepatotoxicity; hypertension; heart failure and edema; renal toxicity and hyperkalemia; anaphylactic reactions; serious skin reactions; hematologic toxicity.
The most common adverse reactions (incidence ≥2%) in patients treated with SPRIX and occurring at a rate at least twice that with placebo include: nasal discomfort; rhinalgia; increased lacrimation; throat irritation; oliguria; rash; bradycardia; decreased urine output; increased ALT and/or AST; hypertension; rhinitis.
In controlled clinical trials in major surgery, primarily knee and hip replacements and abdominal hysterectomies, 1.5% of patients treated with SPRIX experienced serious adverse events of bleeding or hematoma at the operative site versus 0.4% of patients treated with placebo who experienced hematoma.
In patients taking ketorolac or other NSAIDs in clinical trials, the most frequently reported adverse reactions in approximately 1% to 10% of patients are:
- Gastrointestinal (GI): abdominal pain, constipation/diarrhea, dyspepsia, flatulence, GI fullness, GI ulcers (gastric/duodenal), gross bleeding/perforation, heartburn, nausea (incidence >10%), stomatitis, vomiting.
- Other: abnormal renal function, anemia, dizziness, drowsiness, edema, elevated liver enzymes, headache (incidence >10%), hypertension, increased bleeding time, injection site pain, pruritus, purpura, rash, tinnitus, sweating.
Drugs that interfere with hemostasis: increased risk of serious bleeding with use of anticoagulants, antiplatelet agents, selective serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs); concomitant use with pentoxifylline is contraindicated.
ACE inhibitors, angiotensin receptor blockers (ARBs), and beta-blockers: may diminish the antihypertensive effect of these drugs; monitor blood pressure.
ACE Inhibitors and ARBs: In elderly, volume depleted, or those with renal impairment may result in deterioration of renal function; monitor for signs of worsening renal function.
Diuretics: reduces the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients.
Digoxin: has been reported to increase the serum concentration and prolong the half-life of digoxin.
Use in Specific Populations
Pregnancy: Use of NSAIDs during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs in pregnant women starting at 30 weeks gestation.
Infertility: NSAIDs are associated with reversible infertility. Consider withdrawal of SPRIX in women who have difficulties conceiving.
Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which have been generally reversible with supportive care. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare.
