Naproxen for Hip Bursitis
For hip bursitis, use naproxen 500 mg twice daily (or 250 mg every 6-8 hours) at the lowest effective dose for the shortest duration, combined with conservative measures including rest and stretching exercises. If symptoms persist despite 1-2 weeks of NSAIDs and conservative therapy, proceed to corticosteroid injection into the inflamed bursa 1, 2.
Dosing Strategy
Initial dosing: Start with naproxen 500 mg followed by 500 mg every 12 hours, or alternatively 250 mg every 6-8 hours for acute tendonitis and bursitis 1. The initial total daily dose should not exceed 1250 mg, with subsequent daily doses not exceeding 1000 mg.
- Onset of action: Pain relief typically begins within 1 hour 1
- Duration: Use the shortest duration necessary; reassess after 7-14 days
- Dose adjustments: Lower doses should be considered in elderly patients (≥65 years), and those with renal or hepatic impairment 1
Treatment Algorithm
First-Line Conservative Management (0-2 weeks)
- NSAIDs: Naproxen as dosed above
- Rest: Avoid aggravating activities
- Stretching exercises: Focus on lower back and sacroiliac joints 2
- Reassess: Evaluate response at 7-14 days
Second-Line Intervention (if conservative fails)
- Corticosteroid injection: 20-24 mg betamethasone (or equivalent methylprednisolone) with 1% lidocaine into the inflamed bursa 2, 3
- Evidence shows intrabursal steroid injection provides the most rapid decrease in swelling and sustained improvement at 6 weeks 3
Refractory Cases
- Surgical options (iliotibial band release, subgluteal bursectomy, trochanteric reduction osteotomy) are reserved for rare cases of intractable symptoms 2
Important Safety Considerations
Cardiovascular risks: NSAIDs carry increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which may increase with duration of use 4, 1. This risk is particularly relevant in patients with cardiovascular disease or risk factors.
Gastrointestinal risks: NSAIDs cause increased risk of serious GI adverse events including bleeding, ulceration, and perforation 5, 1. The risk is dose-dependent and increases with:
- Age >65 years (2-3.5-fold increase) 6
- Previous GI events (2.5-4-fold increase) 6
- Concomitant warfarin use (3-fold increase) 6
- Concomitant corticosteroid use (2-fold increase) 6
GI protection strategies: For patients with increased GI risk, consider adding a proton pump inhibitor (PPI), which reduces risk of bleeding ulcers by 75-85% 6. PPIs reduce endoscopic GI ulcer risk (RR 0.40,95% CI 0.32-0.51) 5.
Renal considerations: Naproxen is not recommended in patients with moderate to severe renal impairment (creatinine clearance <30 mL/min) 1.
Clinical Pearls
- Naproxen's advantage: The 14-hour half-life allows sustained all-day pain relief with reduced pill burden compared to shorter-acting NSAIDs like ibuprofen 7
- Efficacy data: In shoulder tendinitis/bursitis (similar inflammatory condition), naproxen 500 mg twice daily showed significant pain reduction compared to placebo at both 7 and 14 days 8
- Steroid injection timing: If NSAIDs fail after 1-2 weeks, don't delay corticosteroid injection—evidence shows it provides the most rapid and sustained improvement 3
- Avoid opioids: There is no role for opioid therapy in bursitis management given the effectiveness of NSAIDs and local corticosteroid injection
Common Pitfalls to Avoid
- Exceeding maximum doses: Don't exceed 1250 mg on day 1 or 1000 mg daily thereafter 1
- Prolonged use without reassessment: Evaluate response at 7-14 days; don't continue indefinitely without considering alternative treatments
- Ignoring cardiovascular risk factors: Screen for CV disease before initiating therapy, especially for prolonged use 4
- Missing GI risk factors: Identify high-risk patients who need gastroprotection upfront 6
- Using NSAIDs alone when injection indicated: If conservative therapy fails after 1-2 weeks, proceed to corticosteroid injection rather than continuing ineffective NSAID therapy 2
