WARNINGS

Included as part of the PRECAUTIONS section.

PRECAUTIONS

Limitations Of Use

The total duration of use of SPRIX alone or sequentially with other forms of ketorolac is not to exceed 5 days. SPRIX must not be used concomitantly with other forms of ketorolac or other NSAIDs [see DOSAGE AND ADMINISTRATION].

Gastrointestinal (GI) Effects - Risk Of Ulceration,Bleeding, And Perforation

SPRIX is contraindicated in patients with previously documented peptic ulcers and/or GI bleeding [see CONTRAINDICATIONS].Ketorolac tromethamine can cause serious GI adverse events including bleeding,ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at anytime, with or without warning symptoms, in patients treated with ketorolac.

Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. Minor upper GI problems, such asdyspepsia, are common and may also occur at any time during NSAID therapy. The incidence and severity of GI complications increases with increasing dose of, and duration of treatment with, ketorolac. Even short-term therapy is not without risk. In addition to past history of ulcer disease, other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients, and therefore, special care should be taken in treating this population.

To minimize the potential risk for an adverse GIevent, the lowest effective dose should be used for the shortest possible duration. Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy, and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of SPRIX until a serious GI adverse event is ruled out. For high risk patients,consider alternate therapies that do not involve NSAIDs. Use great care when giving SPRIX to patients with a history of inflammatory bowel disease (ulcerative colitis, Crohn's disease) as their condition may be exacerbated.

Hematological Effects

Because prostaglandins play an important role inhemostasis and NSAIDs affect platelet aggregation as well, use caution with use of ketorolac tromethamine in patients who have coagulation disorders, and monitor these patients carefully. The effects of NSAIDs other than aspirin on platelet function are reversible. Patients on therapeutic doses of anticoagulants (e.g., heparin or dicumarol derivatives) have an increased risk of bleeding complications if given ketorolac tromethamine concurrently; therefore, administer such concomitant therapy only with extreme caution. The concurrent use of ketorolac tromethamine and therapy that affects hemostasis, including prophylactic low dose heparin (2500 to 5000 units q12h), warfarin anddextrans, has not been studied extensively, but may also be associated with an increased risk of bleeding. Until data from such studies are available, carefully weigh the benefits against the risks and use such concomitant therapy in these patients only with extreme caution. Monitor patients receiving therapy that affects hemostasis closely.

In clinical trials, serious adverse events related to bleeding were more common in patients treated with SPRIX than placebo. In clinical trials and in postmarketing experience with ketorolac IV and IMdosing, postoperative hematomas and other signs of wound bleeding have been reported in association with peri-operative use. Therefore, use SPRIX with caution in the postoperative setting when hemostasis is critical.

Anemia is sometimes seen in patients receiving NSAIDs.This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Do not use SPRIX in patients for whom hemostasis is critical [see CONTRAINDICATIONS, DRUG INTERACTIONS].

Renal Effects

Ketorolac and its metabolites are eliminated primarily by the kidneys. Patients with reduced creatinine clearance will have diminished clearance of the drug [see CLINICAL PHARMACOLOGY]. SPRIX is contraindicated in patients with advanced renal impairment [see CONTRAINDICATIONS].

In patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion, administration of anNSAID may cause a dose-dependent reduction in prostaglandin formation and renal blood flow, which may precipitate overt renal decompensation. Decreased intravascular volume such as when oral intake is poor increases the risks of renal toxicity with NSAIDs. Therefore, patients treated with SPRIX should be adequately hydrated. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.

Use SPRIX with caution in patients with impaired renal function, heart failure, liver dysfunction, those taking diuretics or ACEinhibitors, and the elderly. Assess the risks and benefits prior to givingSPRIX to these patients, and follow these patients closely during SPRIXtherapy. Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury such as interstitial nephritis and nephrotic syndrome.

Anaphylactoid Reactions

As with other NSAIDs, anaphylactoid reactions may occur in patients with or without a history of allergic reactions to aspirin orNSAIDs and in patients without known prior exposure to ketorolac. SPRIX should be discontinued immediately in patients with allergic reactions. SPRIX should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs [see CONTRAINDICATIONS, Preexisting Asthma]. Emergency help should be sought in cases where ananaphylactoid reaction occurs.

Cardiovascular Effects

Cardiovascular (CV) Thrombotic Events

Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious CV thrombotic events, myocardial infarction and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event inpatients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms.Patients should be informed about the signs and/or symptoms of serious CVevents and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CVthrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID increases the risk of serious GI events. Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke [see CONTRAINDICATIONS, Gastrointestinal (GI) Effects - Risk of Ulceration, Bleeding, and Perforation, DRUG INTERACTIONS].

Hypertension

NSAIDs can lead to onset of new hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs [see DRUG INTERACTIONS].

Congestive Heart Failure and Edema

Fluid retention, edema, retention of NaCl, oliguria, and elevations of serum urea nitrogen and creatinine have been reported in clinical trials with ketorolac. Therefore, only use SPRIX very cautiously in patients with cardiac decompensation or similar conditions.

Skin Reactions

NSAIDs, including ketorolac, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS),and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Inform patients about the signs and symptoms of serious skin manifestations, and discontinue use of the drug at the first appearance of skin rash or any other sign of hypersensitivity [see CONTRAINDICATIONS].

Pregnancy

Starting at 30 weeks gestation, SPRIX can cause fetal harm when administered to a pregnant woman due to an increased risk of premature closure of the ductus arteriosus. If SPRIX is used at or after 30weeks gestation, the patient should be apprised of the potential hazard to a fetus [see Use In Specific Populations].

Hepatic Effects

Use SPRIX with caution in patients with impaired hepatic function or a history of liver disease. Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs, including ketorolac. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST(approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice, fulminant hepatitis, liver necrosis, and hepatic failure, some of them with fatal outcomes, have been reported [see Renal Effects, CLINICAL PHARMACOLOGY].

Evaluate patients with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, for evidence of the development of a more severe hepatic reaction while on therapy withSPRIX. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), discontinueSPRIX.

Inflammation And Fever

The pharmacological activity of SPRIX in reducing inflammation and fever may diminish the utility of these diagnostic signs in detecting infections.

Preexisting Asthma

Patients with asthma may have aspirin-sensitive asthma.The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, do not administer SPRIX to patients with this form of aspirin sensitivity, and use with caution in patients with preexisting asthma [see CONTRAINDICATIONS, Anaphylactoid Reactions].

Eye Exposure

Avoid contact of SPRIX with the eyes. If eye contact occurs, wash out the eye with water or saline, and consult a physician if irritation persists for more than an hour.

Patient Counseling Information

Instruct patients to read the NSAID Medication Guide that accompanies each prescription dispensed. Inform patients of the following information before initiating therapy with SPRIX.

Instruct all patients to read and closely follow theFDA-approved SPRIX Patient Instructions to ensure proper administration ofSPRIX. When prescribing SPRIX, inform patients or their caregivers of the potential risks of ketorolac treatment, instruct patients to seek medical advice if they develop treatment-related adverse events, advise patients not to give SPRIX to other family members, and advise patients to discard any unused drug.

Limitations Of Use

Instruct patients not to use SPRIX for more than 5 days.Use of SPRIX alone or in combination with any other ketorolac product for more than 5 days increases the risk for serious complications including GI bleeding and renal injury.

Gastrointestinal Effects

Ketorolac is a potent NSAID and, like other NSAIDs, may cause serious side effects, such as gastrointestinal bleeding, which may resulting hospitalization and even fatal outcome. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, instruct patients to be alert for the signs and symptoms of ulcerations and bleeding, and to ask for medical advice when observing any indicative sign or symptom, including epigastric pain, dyspepsia, melena, and hematemesis. Instruct patients of the importance of this follow-up [see CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS].

Renal Effects

SPRIX is eliminated by the kidneys. Advise patients to maintain adequate fluid intake and request medical advice if urine output decreases significantly [see CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS].

Cardiovascular Effects

Ketorolac, like other NSAIDs, may cause serious CVevents, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, advise patients to be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and that they should ask for medical advice when observing any indicative sign or symptoms. Inform patients of the importance of this follow-up [see WARNINGS AND PRECAUTIONS].

Adverse Skin Reactions

Ketorolac, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which may result in hospitalization and even death. Although serious skin reactions may occur without warning, instruct patients to be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Advise patientsto stop the drug immediately if they develop any type of rash, and contacttheir physicians as soon as possible [see WARNINGS AND PRECAUTIONS].

Weight Gain and Edema

Instruct patients to promptly report signs or symptoms of unexplained weight gain or edema to their physicians [see WARNINGS AND PRECAUTIONS].

Hepatotoxicity

Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and “flu-like” symptoms). If these occur, instruct patients to stop therapy and seek immediate medical therapy [see WARNINGS AND PRECAUTIONS].

Anaphylactoid Reactions

Inform patients of the signs of an anaphylactoid reaction (e.g., difficulty breathing, swelling of the face or throat). If these occur, instruct patients to seek immediate emergency help [see CONTRAINDICATIONS,WARNINGS AND PRECAUTIONS].

Effects During Pregnancy

Avoid the use of SPRIX at or beyond 30 weeks gestation as ketorolac can cause premature closure of the ductus arteriosus [see WARNINGS AND PRECAUTIONS, Use In Specific Populations].

Single Day Container

Instruct patients not to use any single bottle of SPRIX for more than one day [see DOSAGE AND ADMINISTRATION].

Nasal Discomfort

Advise patients that they may experience transient, mild to moderate nasal irritation or discomfort upon dosing.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, And Impairment Of Fertility

Carcinogenesis

An 18-month study in mice with oral doses of ketorolac at2 mg/kg/day (approximately 1.5 times the human systemic exposure at the recommended maximum IN dose of 31.5 mg qid, based on area-under-the-plasma-concentration curve [AUC]), and a 24-month study in rats at 5 mg/kg/day (approximately 0.8times the human AUC) showed no evidence of tumorigenicity.

Mutagenesis

Ketorolac was not mutagenic in the Ames test, unscheduledDNA synthesis and repair, or in forward mutation assays. Ketorolac did not cause chromosome breakage in the in vivo mouse micronucleus assay. At 1590μg/mL and at higher concentrations, ketorolac increased the incidence of chromosomal aberrations in Chinese hamster ovarian cells.

Impairment of fertility

Impairment of fertility did not occur in male or female rats at oral doses of 9 mg/kg (approximately 1.5 times the human AUC) and 16mg/kg (approximately 2.7 times the human AUC) of ketorolac, respectively.

Use In Specific Populations

Pregnancy

Teratogenic Effects

Pregnancy Category C prior to 30 weeks gestation;Category D starting at 30 weeks gestation.

SPRIX can cause fetal harm when administered to a pregnant woman. Human data demonstrate that use of NSAIDs at or after 30 weeks gestation increases the risk of premature closure of the ductus arteriosus. If SPRIX is used at or after 30 weeks gestation, the patient should be apprised of the potential hazard to a fetus. There are no adequate, well-controlled studies in pregnant women. Prior to 30 weeks gestation, SPRIX should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Reproduction studies have been performed during organogenesis using daily oral doses of ketorolac tromethamine at 3.6 mg/kg(0.6 times the human systemic exposure at the recommended maximum IN dose of31.5 mg qid, based on area-under-the-plasma-concentration curve [AUC]) in rabbits and at 10 mg/kg (1.7 times the human AUC) in rats. These studies did not reveal evidence of teratogenicity or other adverse developmental outcomes.However, because animal dosing was limited by maternal toxicity, these studies do not adequately assess ketorolac's potential to cause adverse developmental outcomes in humans.

Labor And Delivery

The effects of SPRIX on labor and delivery in pregnant women are unknown. In rat studies, maternal exposure to NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, increased the incidence of dystocia and delayed parturition, and decreased pup survival.

Nursing Mothers

Ketorolac is excreted in human milk. Limited data from one published study involving ten nursing mothers 2-6 days postpartum showed low levels of ketorolac in breast milk. Levels were undetectable (less than 5ng/mL) in 4 of the patients. After a single administration of 10 mg ketorolac, the maximum milk concentration observed was 7.3 ng/mL, and the maximum milk to plasma ratio was 0.037. After 1 day of dosing (10mg every 6 hours), the maximum milk concentration was 7.9 ng/mL, and the maximum milk-to-plasma ratio was0.025. Assuming a daily intake of 400-1000 mL of human milk per day and a maternal body weight of 60 kg, the calculated maximum daily infant exposure was0.00263 mg/kg/day, which is 0.4% of the maternal weight adjusted dose. Exercise caution when administering SPRIX to a nursing woman. Available information has not shown any specific adverse events in nursing infants; however, instruct patients to contact their infant's health care provider if they note any adverse events.

Pediatric Use

The safety and effectiveness of ketorolac in pediatric patients 17 years of age and younger have not been established.

Geriatric Use ( ≥ 65 years of age)

Exercise caution when treating the elderly (65 years and older) with SPRIX. Carefully consider the potential benefits and risks of SPRIXand other treatment options before deciding to use SPRIX. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY]. After observing the response to initial therapy with SPRIX,then adjust the dose and frequency to suit an individual patient's needs.
