Pain Management with Ketorolac and Aspirin

Contraindications and Risks

The American Heart Association recommends aspirin 162-325 mg for adults experiencing non-traumatic chest pain, which improves survival in patients with myocardial infarction by reducing platelet aggregation 1
The combination of ketorolac and aspirin increases the risk of gastrointestinal bleeding and other hemorrhagic complications, even with a single dose of each medication 1
Aspirin and ketorolac both affect platelet function and hemostasis, and their concurrent use may be associated with an increased risk of bleeding 1

Acetaminophen 650-1000 mg orally or IV can be considered for pain management, as an alternative to IV ketorolac 1
Opioid analgesics, such as low-dose morphine (2-4 mg IV) or hydromorphone (0.5-1 mg IV), can be used for severe pain management, as an alternative to IV ketorolac 1

If ketorolac is absolutely necessary for pain management, it is recommended to wait at least 8-12 hours after aspirin administration, consider reduced dosing (no more than 15 mg IV), and monitor closely for signs of bleeding 1
