   2. Renal Impairment

   1. Consider other NSAIDs which are typically as effective, with less Gastrointestinal Bleeding risk
   2. Maximum: 40 mg per day
   3. Regular dose
      1. First dose: 20 mg PO (two 10 mg tablets)
      2. Subsequent dosing: 10 mg PO q4-6 hours prn

    4. Bleeding risk
11. Efficacy
    1. Most NSAIDs have equivalent efficacy to parenteral Ketorolac (and to some Opioids)
    2. Equivalents to Toradol 60 mg IM
       1. Morphine 12 mg IM
       2. Most NSAIDS (and similar onset of action to IM Injection)
          1. Ibuprofen 800 mg orally
          2. Naprosyn 500 mg orally
    3. Advantages over Morphine in ER with blunt limb Trauma
       1. Toradol has longer duration
       2. Toradol less adverse effects
