ADVERSE REACTIONS
Adverse reaction rates increase with higher doses of ketorolac tromethamine. Practitioners should be alert for the severe complications of treatment with ketorolac tromethamine, such as G.I. 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 ketorolac tromethamine is indicated, especially when the drug is used inappropriately.
In patients taking ketorolac tromethamine or other NSAIDs in clinical trials, the most frequently reported adverse experiences in approximately 1% to 10% of patients are:
| |
Gastrointestinal (GI) experiences including: | |
abdominal pain constipation/diarrhea dyspepsia flatulence GI fullness GI ulcers (gastric/duodenal) | gross bleeding/perforation heartburn nausea* stomatitis vomiting |
| |
abnormal renal function anemia dizziness drowsiness edema elevated liver enzymes headaches* hypertension | increased bleeding time injection site pain pruritus purpura rashes tinnitus sweating |
Additional adverse experiences reported occasionally (<1% in patients taking ketorolac tromethamine or other NSAIDs in clinical trials) include:
Body as a Whole: fever, infections, sepsis
Cardiovascular: congestive heart failure, palpitation, pallor, tachycardia, syncope
Dermatologic: alopecia, photosensitivity, urticaria
Gastrointestinal: anorexia, dry mouth, eructation, esophagitis, excessive thirst, gastritis, glossitis, hematemesis, hepatitis, increased appetite, jaundice, melena, rectal bleeding
Hemic and Lymphatic: ecchymosis, eosinophilia, epistaxis, leukopenia, thrombocytopenia
Metabolic and Nutritional: weight change
Nervous System: abnormal dreams, abnormal thinking, anxiety, asthenia, confusion, depression, euphoria, extrapyramidal symptoms, hallucinations, hyperkinesis, inability to concentrate, insomnia, nervousness, paresthesia, somnolence, stupor, tremors, vertigo, malaise
Reproductive, female: infertility
Respiratory: asthma, cough, dyspnea, pulmonary edema, rhinitis
Special Senses: abnormal taste, abnormal vision, blurred vision, hearing loss
Urogenital: cystitis, dysuria, hematuria, increased urinary frequency, interstitial nephritis, oliguria/polyuria, proteinuria, renal failure, urinary retention
Other rarely observed reactions (reported from postmarketing experience in patients taking ketorolac tromethamine or other NSAIDs) are:
Body as a Whole: angioedema, death, hypersensitivity reactions such as anaphylaxis, anaphylactoid reaction, laryngeal edema, tongue edema (see WARNINGS), myalgia
Cardiovascular: arrhythmia, bradycardia, chest pain, flushing, hypotension, myocardial infarction, vasculitis
Dermatologic: exfoliative dermatitis, erythema multiforme, Lyell's syndrome, bullous reactions including Stevens-Johnson syndrome and toxic epidermal necrolysis
Gastrointestinal: acute pancreatitis, liver failure, ulcerative stomatitis, exacerbation of inflammatory bowel disease (ulcerative colitis, Crohn's disease)
Hemic and Lymphatic: agranulocytosis, aplastic anemia, hemolytic anemia, lymphadenopathy, pancytopenia, post operative wound hemorrhage (rarely requiring blood transfusion — see Boxed WARNING, WARNINGS, and PRECAUTIONS)
Metabolic and Nutritional: hyperglycemia, hyperkalemia, hyponatremia
Nervous System: aseptic meningitis, convulsions, coma, psychosis
Respiratory: bronchospasm, respiratory depression, pneumonia
Special Senses: conjunctivitis
Urogenital: flank pain with or without hematuria and/or azotemia, hemolytic uremic syndrome
Postmarketing Surveillance Study
A large postmarketing observational, nonrandomized study, involving approximately 10,000 patients receiving ketorolac tromethamine, 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 tromethamine (see Table 3A).
