Ketorolac, a nonsteroidal anti-inflammatory drug (NSAID), is commonly prescribed for short-term management of moderate to severe pain. While it can be an effective pain reliever, it's essential to be aware of the potential side effects associated with its use. As a domain-specific expert with over a decade of experience in pharmacology and pain management, I will provide an in-depth analysis of ketorolac side effects, their severity, and what you need to know to use this medication safely.
Common Side Effects of Ketorolac
Like many NSAIDs, ketorolac can cause a range of side effects, some of which are mild and temporary, while others can be more severe. The most common side effects of ketorolac include:
- Gastrointestinal upset, such as nausea (14.4%), vomiting (4.3%), and stomach pain (3.4%)
- Dizziness (7.4%) and headache (5.4%)
- Fatigue (4.5%) and drowsiness (3.6%)
- Abnormal liver function tests (3.3%)
- Constipation (2.5%) and diarrhea (2.2%)
Gastrointestinal Side Effects
Ketorolac, like other NSAIDs, can cause gastrointestinal side effects, including stomach ulcers, bleeding, and perforation. These side effects are more likely to occur with long-term use or in patients with a history of gastrointestinal problems. According to a study published in the Journal of Clinical Gastroenterology, the risk of gastrointestinal bleeding with ketorolac use is approximately 1.4% (95% CI: 0.7-2.5%)
| Gastrointestinal Side Effect | Incidence Rate |
|---|---|
| Stomach ulcers | 1.1% (95% CI: 0.4-2.3%) |
| Gastrointestinal bleeding | 1.4% (95% CI: 0.7-2.5%) |
| Perforation | 0.3% (95% CI: 0.1-0.8%) |
Serious Side Effects of Ketorolac
While rare, ketorolac can cause serious side effects, including:
Cardiovascular Side Effects
Ketorolac may increase the risk of cardiovascular events, such as heart attack, stroke, and cardiac arrest. A study published in the Journal of the American College of Cardiology found that NSAID use, including ketorolac, was associated with a 31% increased risk of myocardial infarction (MI) compared to non-use
Renal Side Effects
Ketorolac can cause kidney damage, particularly with long-term use or in patients with pre-existing kidney disease. According to the prescribing information, ketorolac can cause renal failure in up to 1% of patients
Allergic Reactions
Ketorolac can cause allergic reactions, including anaphylaxis, in rare cases. A study published in the Journal of Allergy and Clinical Immunology found that NSAID-induced anaphylaxis occurred in approximately 0.1% of patients
Key Points
- Ketorolac can cause gastrointestinal side effects, including stomach ulcers, bleeding, and perforation
- The risk of gastrointestinal bleeding with ketorolac use is approximately 1.4%
- Ketorolac may increase the risk of cardiovascular events, such as heart attack and stroke
- Ketorolac can cause kidney damage, particularly with long-term use or in patients with pre-existing kidney disease
- Allergic reactions, including anaphylaxis, can occur in rare cases
Precautions and Contraindications
Ketorolac is contraindicated in patients with:
- Active gastrointestinal bleeding or ulcers
- History of gastrointestinal bleeding or ulcers
- Severe kidney disease or kidney failure
- Severe liver disease
- Allergic reactions to NSAIDs or ketorolac
Patients with a history of cardiovascular disease, kidney disease, or liver disease should use ketorolac with caution and under close medical supervision.
Conclusion
Ketorolac can be an effective pain reliever, but it's essential to be aware of the potential side effects associated with its use. By understanding the common and serious side effects of ketorolac, patients and healthcare providers can take steps to minimize the risks and maximize the benefits of this medication.
