Ibuprofen
NSAID for mild to moderate pain, inflammation, and fever
Indications
- PO only
Contraindications
- Known hypersensitivity to ibuprofen or other anti-inflammatories including aspirin
- Known or suspected renal dysfunction (GFR or Creatinine Clearance less than 30 mL/min or patient identifies as having kidney dysfunction)
- Concern for severe active bleeding (trauma, intracranial hemorrhage, GI bleeding)
- Pregnancy
- Use of anticoagulant (eg. apixaban, rivaroxaban, warfarin, edoxaban, dabigatran)
Cautions
- Severe volume depletion/dehydration
- Active cardiac emergency (myocardial infarction)
- Anti-inflammatory within the last 6-12 hours (eg. ibuprofen, celecoxib, naproxen)
Adult Dosages
Analgesia
- 300-400 mg PO; may repeat every 4-6 hours; maximum daily dose 1,200 mg/day
Pediatric Considerations
Analgesia
- 10 mg/kg PO; may repeat once after 6 hours; maximum daily dose 40 mg/kg/day
Adverse Effects
- The most common adverse reactions involve gastrointestinal upset, ranging from abdominal discomfort to gastric ulceration, bleeding, and perforation
- These events are unlikely following a single, out-of-hospital dose of ibuprofen, but care should be exercised in patients with a recent history of NSAID use
Additional Information
Mechanism of Action
Inhibits prostaglandin synthesis, reducing pain, inflammation, and pyrexia.
Pharmacokinetics
| Effect | Onset | Peak | Duration |
|---|---|---|---|
| Analgesic | 30-60 minutes | 1-2 hours | 4-6 hours |
| Antipyretic | 30 minutes to 2.5 hours | 2-4 hours | 6-8 hours |
Overdose
The most common symptoms of NSAID overdose are gastrointestinal irritation and CNS depression. Care is primarily supportive.
Warnings and Precautions
Alternative treatment options should be considered in patients with a history of gastrointestinal, renal, or significant cardiovascular disease: ibuprofen, and all NSAIDs, have the potential to cause significant adverse reactions. The risk appears to increase with dose, duration of therapy, and underlying risk factors.
Drug Interactions
As a class of medications, NSAIDs may raise blood pressure, limiting the effectiveness of antihypertensives.
