Treatment Options for Chronic Hip Pain in an Elderly Female When Acetaminophen Fails
For an elderly female with chronic left hip pain unresponsive to acetaminophen, NSAIDs at the lowest effective dose should be added or substituted, with mandatory gastroprotection using a proton pump inhibitor given her age-related increased risk of gastrointestinal bleeding. 1
Immediate Next Steps: NSAID Therapy with Gastroprotection
The most appropriate pharmacologic escalation is to prescribe either ibuprofen or naproxen at the lowest effective dose, co-prescribed with a proton pump inhibitor (PPI). 1
Specific NSAID Recommendations:
- Ibuprofen 400-600 mg three times daily or naproxen 250-375 mg twice daily are reasonable first choices in elderly patients with low baseline gastrointestinal risk 1
- Mandatory co-prescription of a PPI (such as omeprazole 20 mg daily) reduces the relative risk of endoscopic gastric ulcer to 0.40 (95% CI 0.32 to 0.51) compared to NSAIDs alone 1
- NSAIDs demonstrate an effect size of 0.69 for pain relief in hip osteoarthritis with a number needed to treat of 4 1
Critical Safety Considerations Before Prescribing NSAIDs:
Cardiovascular Assessment:
- Evaluate for history of myocardial infarction, stroke, heart failure, or uncontrolled hypertension, as NSAIDs carry cardiovascular risks 1
- Avoid diclofenac specifically due to higher cardiovascular event risk compared to other traditional NSAIDs 1
- If the patient takes aspirin, avoid ibuprofen due to interference with aspirin's antiplatelet effect; naproxen is preferred 1
Renal Function Assessment:
- Check baseline serum creatinine and estimated glomerular filtration rate (eGFR), as NSAIDs adversely affect renal function, particularly in elderly patients 1, 2
- NSAIDs should be used with extreme caution or avoided if eGFR <30 mL/min 1
Medication Interaction Review:
- Exercise particular caution if the patient takes ACE inhibitors, diuretics, or antiplatelet agents due to dangerous drug interactions 2
- NSAIDs may adversely affect blood pressure control in patients on antihypertensive medications 1
Alternative Pharmacologic Options
If NSAIDs Are Contraindicated:
Tramadol 25-50 mg every 6 hours as needed can be considered as an alternative analgesic 3, 4
- Tramadol appears useful for patients who do not receive adequate pain relief with acetaminophen and are at risk for NSAID-related side effects 4
- Reduce the dose by 20-25% in patients over 60 to prevent morphine accumulation, over-sedation, and delirium 2
Topical NSAIDs (diclofenac gel) provide localized pain relief with minimal systemic absorption 3, 5
- Topical NSAIDs demonstrate efficacy similar to oral NSAIDs with an adverse event incidence similar to placebo 5
- Significantly lower cardiovascular and gastrointestinal risks compared to oral formulations 3
Duloxetine 30 mg daily for one week, then 60 mg daily if tolerated 3
- Particularly effective in older patients (>65 years) with osteoarthritis 3
- Avoids the cardiovascular and gastrointestinal risks of NSAIDs 3
Opioid Therapy as Last Resort:
Opioids should be reserved exclusively for breakthrough pain at the lowest effective dose for the shortest duration after exhausting non-opioid options 1, 2
- Before initiating opioid therapy, assess: (1) whether alternative therapies have equivalent or better therapeutic index, (2) whether the patient has medical problems increasing risk of opioid-related adverse effects, and (3) whether the patient can manage therapy responsibly 1
- Opioids increase risk of falls, cognitive impairment, constipation, nausea, and delirium in elderly patients 6, 2
- Initiate prophylactic laxatives when starting opioids to prevent constipation 6
Essential Non-Pharmacologic Interventions
Physical therapy is a strong evidence-based treatment for mild-to-moderate hip osteoarthritis and should be initiated concurrently with pharmacologic management. 1, 2
Specific Physical Therapy Components:
- Structured exercise programs including strengthening exercises for hip musculature (quadriceps, hip flexors, hip extensors) 1
- Pool therapy in warm water (86°F) provides analgesia, reduces joint loading, and enhances pain-free motion 1
- Avoid high-impact aerobic training, as rapid application of loads may produce pain or damage 1
- Referral to Physical Medicine and Rehabilitation (PMR) for development of an individualized program using validated outcome measures 2
Additional Non-Pharmacologic Adjuncts:
- Immobilization techniques, ice packs, and supportive dressings carry minimal risk and may provide additional relief 2
- Consider assistive devices (cane, walker) to reduce joint loading 1
Diagnostic Imaging and Interventional Options
Obtain anteroposterior and lateral radiographs of the hip and pelvis if not already performed to confirm osteoarthritis and rule out other pathology 2
Ultrasound-guided intra-articular corticosteroid injection can be considered for both diagnostic and therapeutic purposes 2
- Well-supported for hip osteoarthritis and helps confirm intra-articular pathology as the pain source 2
Critical Pitfalls to Avoid
Do not prescribe NSAIDs without gastroprotection in elderly patients, as age is an independent risk factor for gastrointestinal bleeding 1
Do not overlook referred pain from the lumbar spine, sacroiliac joints, or knee—maintain a broad differential diagnosis 2
Do not proceed to surgical referral without exhausting conservative options including physical therapy and pharmacologic management 2
Monitor for NSAID-related complications including blood pressure changes, peripheral edema, and renal function deterioration 1, 2
Monitoring Plan
- Reassess pain and functional status at 2-4 weeks after initiating NSAID therapy 2
- Monitor renal function (serum creatinine, eGFR) every 3-6 months or 1-2 weeks after starting NSAIDs 3
- Evaluate for gastrointestinal symptoms at each visit and discontinue NSAIDs if dyspepsia, abdominal pain, or signs of bleeding develop 1
- Assess cardiovascular status including blood pressure and signs of fluid retention 1
