Carefully consider the potential benefits and risks of Dolac (ketorolac tromethamine) and other treatment options before deciding to use Dolac (ketorolac tromethamine). Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
Dolac (ketorolac tromethamine) ORAL is indicated for the short-term ( ≤ 5 days) management of moderately severe acute pain that requires analgesia at the opioid level, usually in a postoperative setting. Therapy should always be initiated with IV or IM dosing of ketorolac tromethamine, and Dolac (ketorolac tromethamine) ORAL is to be used only as continuation treatment, if necessary.
The total combined duration of use of Dolac (ketorolac tromethamine) ORAL and ketorolac tromethamine is not to exceed 5 days of use because of the potential of increasing the frequency and severity of adverse reactions associated with the recommended doses (see WARNINGS, PRECAUTIONS, DOSAGE AND ADMINISTRATION, and ADVERSE REACTIONS). Patients should be switched to alternative analgesics as soon as possible, but Dolac (ketorolac tromethamine) ORAL therapy is not to exceed 5 days.
Carefully consider the potential benefits and risks of Dolac (ketorolac tromethamine) and other treatment options before deciding to use Dolac (ketorolac tromethamine). Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals. In adults, the combined duration of use of IV or IM dosing of ketorolac tromethamine and Dolac (ketorolac tromethamine) ORAL is not to exceed 5 days. In adults, the use of Dolac (ketorolac tromethamine) ORAL is only indicated as continuation therapy to IV or IM dosing of ketorolac tromethamine.
Transition from IV or IM dosing of ketorolac tromethamine (single- or multiple-dose) to multiple-dose Dolac (ketorolac tromethamine) ORAL:
Patients age 17 to 64: 20 mg PO once followed by 10 mg q4-6 hours prn not > 40 mg/day
Patients age ≥ 65, renally impaired, and/or weight < 50 kg (110 lbs): 10 mg PO once followed by 10 mg q4-6 hours prn not > 40 mg/day
Oral formulation should not be given as an initial dose
Use minimum effective dose for the individual patient
Do not shorten dosing interval of 4 to 6 hours
Total duration of treatment in adult patients: the combined duration of use of IV or IM dosing of ketorolac tromethamine and Dolac (ketorolac tromethamine) ORAL is not to exceed 5 days.
The following table summarizes Dolac (ketorolac tromethamine) ORAL dosing instructions in terms of age group:
Table 4 :Summary of Dosing Instructions
|Patient Population||DolacORA L(following IV or IM dosing of ketorolac tromethamine)|
|Age < 17 years||Oral not approved|
|Adult Age 17 to 64 years||20 mg once, then 10 mg q4-6 hours prn not > 40 mg/day|
|Adult Age ≥ 65 years, renally impaired, and/or weight < 50 kg||10 mg once, then 10 mg q4-6 hours prn not > 40 mg/day|
Dolac is contraindicated in patients with previously demonstrated hypersensitivity to ketorolac tromethamine.
Dolac is contraindicated in patients with active peptic ulcer disease, in patients with recent gastrointestinal bleeding or perforation and in patients with a history of peptic ulcer disease or gastrointestinal bleeding.
Dolac should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS: Anaphylactoid Reactions, and PRECAUTIONS: Preexisting Asthma).
Dolac is contraindicated as prophylactic analgesic before any major surgery.
Dolac is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS).
Dolac is contraindicated in patients with advanced renal impairment or in patients at risk for renal failure due to volume depletion (see WARNINGS for correction of volume depletion).
Dolac is contraindicated in labor and delivery because, through its prostaglandin synthesis inhibitory effect, it may adversely affect fetal circulation and inhibit uterine contractions, thus increasing the risk of uterine hemorrhage.
Dolac inhibits platelet function and is, therefore, contraindicated in patients with suspected or confirmed cerebrovascular bleeding, hemorrhagic diathesis, incomplete hemostasis and those at high risk of bleeding (see WARNINGS and PRECAUTIONS).
Dolac is contraindicated in patients currently receiving aspirin or NSAIDs because of the cumulative risks of inducing serious NSAID-related adverse events.
The concomitant use of Dolac and probenecid is contraindicated.
The concomitant use of ketorolac tromethamine and pentoxifylline is contraindicated.
(see also BOXED WARNING)
The total combined duration of use of DolacORAL and IV or IM dosing of ketorolac tromethamine is not to exceed 5 days in adults. Dolac (ketorolac tromethamine) ORAL is not indicated for use in pediatric patients.
The most serious risks associated with Dolac (ketorolac tromethamine) are:
Dolac (ketorolac tromethamine) is contraindicated in patients with previously documented peptic ulcers and/or GI bleeding. Dolac (ketorolac tromethamine) can cause serious gastrointestinal (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 any time, with or without warning symptoms, in patients treated with Dolac (ketorolac tromethamine).
Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. Minor upper gastrointestinal problems, such as dyspepsia, are common and may also occur at any time during NSAID therapy. The incidence and severity of gastrointestinal complications increases with increasing dose of, and duration of treatment with, Dolac (ketorolac tromethamine). Do not use Dolac (ketorolac tromethamine) for more than five days. However, 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 GI event, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should 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 Dolac (ketorolac tromethamine) until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered.
NSAIDs should be given with care to patients with a history of inflammatory bowel disease (ulcerative colitis, Crohn's disease) as their condition may be exacerbated.
Because prostaglandins play an important role in hemostasis and NSAIDs affect platelet aggregation as well, use of Dolac (ketorolac tromethamine) in patients who have coagulation disorders should be undertaken very cautiously, and those patients should be carefully monitored. Patients on therapeutic doses of anticoagulants (eg, heparin or dicumarol derivatives) have an increased risk of bleeding complications if given Dolac (ketorolac tromethamine) concurrently; therefore, physicians should administer such concomitant therapy only extremely cautiously. The concurrent use of Dolac (ketorolac tromethamine) and therapy that affects hemostasis, including prophylactic low-dose heparin (2500 to 5000 units q12h), warfarin and dextrans have not been studied extensively, but may also be associated with an increased risk of bleeding. Until data from such studies are available, physicians should carefully weigh the benefits against the risks and use such concomitant therapy in these patients only extremely cautiously. Patients receiving therapy that affects hemostasis should be monitored closely.
In postmarketing experience, postoperative hematomas and other signs of wound bleeding have been reported in association with the peri-operative use of IV or IM dosing of ketorolac tromethamine. Therefore, peri-operative use of Dolac (ketorolac tromethamine) should be avoided and postoperative use be undertaken with caution when hemostasis is critical (see PRECAUTIONS).
Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.
Dolac (ketorolac tromethamine) and its metabolites are eliminated primarily by the kidneys, which, in patients with reduced creatinine clearance, will result in diminished clearance of the drug (see CLINICAL PHARMACOLOGY). Therefore, Dolac (ketorolac tromethamine) should be used with caution in patients with impaired renal function (see DOSAGE AND ADMINISTRATION) and such patients should be followed closely. With the use of Dolac (ketorolac tromethamine) , there have been reports of acute renal failure, interstitial nephritis and nephrotic syndrome.
Dolac (ketorolac tromethamine) is contraindicated in patients with serum creatinine concentrations indicating advanced renal impairment (see CONTRAINDICATIONS). Dolac (ketorolac tromethamine) should be used with caution in patients with impaired renal function or a history of kidney disease because it is a potent inhibitor of prostaglandin synthesis. Because patients with underlying renal insufficiency are at increased risk of developing acute renal decompensation or failure, the risks and benefits should be assessed prior to giving Dolac (ketorolac tromethamine) to these patients.
As with other NSAIDs, anaphylactoid reactions may occur in patients without a known previous exposure or hypersensitivity to Dolac (ketorolac tromethamine). Dolac (ketorolac tromethamine) 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 and PRECAUTIONS: Preexisting Asthma). Anaphylactoid reactions, like anaphylaxis, may have a fatal outcome. Emergency help should be sought in cases where an anaphylactoid reaction occurs.
Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (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 in patients 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 CV events and the steps to take if they occur.
There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation). 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).
NSAIDs, including Dolac (ketorolac tromethamine) , 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. NSAIDs, including Dolac (ketorolac tromethamine) , should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.
Fluid retention, edema, retention of NaCl, oliguria, elevations of serum urea nitrogen and creatinine have been reported in clinical trials with Dolac (ketorolac tromethamine). Therefore, Dolac (ketorolac tromethamine) should be used only very cautiously in patients with cardiac decompensation, hypertension or similar conditions.
NSAIDS, including Dolac (ketorolac tromethamine) , 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. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity.
In late pregnancy, as with other NSAIDs, Dolac (ketorolac tromethamine) should be avoided because it may cause premature closure of the ductus arteriosus.
Dolac (ketorolac tromethamine) cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids.
The pharmacological activity of Dolac (ketorolac tromethamine) in reducing inflammation may diminish the utility of this diagnostic sign in detecting complications of presumed noninfectious, painful conditions.
Dolac (ketorolac tromethamine) should be used 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 Dolac (ketorolac tromethamine). 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 and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported.
A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with Dolac (ketorolac tromethamine). If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (eg, eosinophilia, rash, etc.), Dolac (ketorolac tromethamine) should be discontinued.
Anemia is sometimes seen in patients receiving NSAIDs, including Dolac (ketorolac tromethamine). This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including Dolac (ketorolac tromethamine) , should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving Dolac (ketorolac tromethamine) who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored.
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 nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, Dolac (ketorolac tromethamine) should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma.
Dolac (ketorolac tromethamine) is a potent NSAID and may cause serious side effects such as gastrointestinal bleeding or kidney failure, which may result in hospitalization and even fatal outcome.
Physicians, when prescribing Dolac (ketorolac tromethamine) , should inform their patients or their guardians of the potential risks of Dolac treatment (see BOXED WARNING, WARNINGS, PRECAUTIONS, and ADVERSE REACTIONS sections), instruct patients to seek medical advice if they develop treatment-related adverse events, and advise patients not to give Dolac (ketorolac tromethamine) ORAL to other family members and to discard any unused drug.
Remember that the total combined duration of use of DolacORAL and IV or IM dosing of ketorolac tromethamine is not to exceed 5 days in adults. Dolac (ketorolac tromethamine) ORAL is not indicated for use in pediatric patients.
Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed.
Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs, should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, Dolac (ketorolac tromethamine) should be discontinued.
An 18-month study in mice with oral doses of ketorolac tromethamine at 2 mg/kg/day (0.9 times the human systemic exposure at the recommended IM or IV dose of 30 mg qid, based on area-under-the-plasma-concentration curve [AUC]), and a 24-month study in rats at 5 mg/kg/day (0.5 times the human AUC) showed no evidence of tumorigenicity. Ketorolac tromethamine was not mutagenic in the Ames test, unscheduled DNA synthesis and repair, and in forward mutation assays.
Ketorolac tromethamine did not cause chromosome breakage in the in vivo mouse micronucleus assay. At 1590 μg/mL and at higher concentrations, ketorolac tromethamine increased the incidence of chromosomal aberrations in Chinese hamster ovarian cells.
Impairment of fertility did not occur in male or female rats at oral doses of 9 mg/kg (0.9 times the human AUC) and 16 mg/kg (1.6 times the human AUC) of ketorolac tromethamine, respectively.
Reproduction studies have been performed during organogenesis using daily oral doses of ketorolac tromethamine at 3.6 mg/kg (0.37 times the human AUC) in rabbits and at 10 mg/kg (1.0 times the human AUC) in rats. Results of these studies did not reveal evidence of teratogenicity to the fetus. However, animal reproduction studies are not always predictive of human response.
Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Oral doses of ketorolac tromethamine at 1.5 mg/kg (0.14 times the human AUC), administered after gestation Day 17, caused dystocia and higher pup mortality in rats.
There are no adequate and well-controlled studies of Dolac (ketorolac tromethamine) in pregnant women. Dolac (ketorolac tromethamine) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
The use of Dolac (ketorolac tromethamine) is contraindicated in labor and delivery because, through its prostaglandin synthesis inhibitory effect, it may adversely affect fetal circulation and inhibit uterine contractions, thus increasing the risk of uterine hemorrhage (see CONTRAINDICATIONS).
The use of ketorolac tromethamine, as with any drug known to inhibit cyclooxygenase/prostaglandin synthesis, may impair fertility and is not recommended in women attempting to conceive. In women who have difficulty conceiving or are undergoing investigation of infertility, withdrawal of ketorolac tromethamine should be considered.
After a single administration of 10 mg of Dolac (ketorolac tromethamine) ORAL to humans, 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 (qid), the maximum milk concentration was 7.9 ng/mL, and the maximum milk-to-plasma ratio was 0.025. Because of the possible adverse effects of prostaglandin-inhibiting drugs on neonates, use in nursing mothers is contraindicated.
Dolac (ketorolac tromethamine) ORAL is not indicated for use in pediatric patients. The safety and effectiveness of Dolac (ketorolac tromethamine) ORAL in pediatric patients below the age of 17 have not been established.
Because ketorolac tromethamine may be cleared more slowly by the elderly (see CLINICAL PHARMACOLOGY) who are also more sensitive to the dose-related adverse effects of NSAIDs (see WARNINGS: Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation), extreme caution, reduced dosages (see DOSAGE AND ADMINISTRATION), and careful clinical monitoring must be used when treating the elderly with Dolac (ketorolac tromethamine).
Adverse reaction rates increase with higher doses of Dolac (ketorolac tromethamine). Practitioners should be alert for the severe complications of treatment with Dolac (ketorolac tromethamine) , such as GI ulceration, bleeding and perforation, postoperative bleeding, acute renal failure, anaphylactic and anaphylactoid reactions and liver failure (see BOXED WARNING, WARNINGS, PRECAUTIONS, and DOSAGE AND ADMINISTRATION). These NSAID-related complications can be serious in certain patients for whom Dolac (ketorolac tromethamine) is indicated, especially when the drug is used inappropriately.
In patients taking Dolac (ketorolac tromethamine) or other NSAIDs in clinical trials, the most frequently reported adverse experiences in approximately 1% to 10% of patients are:

A large postmarketing observational, nonrandomized study, involving approximately 10,000 patients receiving ketorolac tromethamineIV/IM, demonstrated that the risk of clinically serious gastrointestinal (GI) bleeding was dose-dependent (see Tables 3A and 3B). This was particularly true in elderly patients who received an average daily dose greater than 60 mg/day of ketorolac tromethamineIV/IM (see Table 3A).
Table 3 Incidence of Clinically Serious GI Bleeding as Related to Age, Total Daily Dose, and History of GI Perforation, Ulcer, Bleeding (PUB) After up to 5 Days of Treatment With Ketorolac TromethamineIV/IMA.
|A. Adult Patients Without History of PUB|
|Age of Patients||Total Daily Dose of Ketorolac TromethamineIV/IM|
|≤ 60 mg||> 60 to 90 mg||> 90 to 120 mg||> 120 mg|
|< 65 years of age||0.4%||0.4%||0.9%||4.6%|

Symptoms following acute NSAID overdoses are usually limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which are generally reversible with supportive care. Gastrointestinal bleeding can occur. Hypertension, acute renal failure, respiratory depression and coma may occur, but are rare. Anaphylactoid reactions have been reported with therapeutic ingestion of NSAIDs, and may occur following an overdose.
Patients should be managed by symptomatic and supportive care following a NSAIDs overdose. There are no specific antidotes. Emesis and/or activated charcoal (60 g to 100 g in adults, 1 g/kg to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or following a large oral overdose (5 to 10 times the usual dose). Forced diuresis, alkalization of urine, hemodialysis or hemoperfusion may not be useful due to high protein binding. Single overdoses of Dolac have been variously associated with abdominal pain, nausea, vomiting, hyperventilation, peptic ulcers and/or erosive gastritis and renal dysfunction which have resolved after discontinuation of dosing.
