Non-Narcotic Options for Managing Acute Pain
Topical NSAIDs with or without menthol gel should be used as first-line therapy for acute musculoskeletal pain due to their superior benefit-harm ratio compared to other analgesics. 1
First-Line Pharmacologic Options
Topical Treatments
- Topical NSAIDs: First-line therapy for non-low back musculoskeletal injuries
Oral Medications
Oral NSAIDs (e.g., naproxen, ibuprofen):
- Effective for most types of acute pain including low back pain, dental pain, and kidney stone pain 1
- Dosing: For naproxen, typically 500mg initially, then 250mg every 6-8 hours as needed 2
- Should be used at lowest effective dose for shortest duration possible 2
- Contraindications: History of GI bleeding, cardiovascular disease, renal impairment 2
Acetaminophen:
Non-Pharmacologic Options
- Heat therapy: Effective for acute back pain 4
- Cold therapy: Ice, elevation for acute injuries
- Specific acupressure: Reduces pain and improves physical function 1
- TENS (Transcutaneous Electrical Nerve Stimulation): Effective for pain reduction 1
- Manual therapy/spinal manipulation: Beneficial for back pain with radiculopathy 4
- Rest, immobilization, or exercise: As appropriate for specific conditions 1
Second-Line Pharmacologic Options
Muscle Relaxants
- Cyclobenzaprine:
Combination Therapies
- Acetaminophen + NSAIDs: Can provide synergistic pain relief 5
- Acetaminophen + muscle relaxants: May be effective for certain conditions 4
Pain-Specific Recommendations
Low Back Pain
- First-line: NSAIDs or acetaminophen 1
- Avoid opioids (including tramadol) 1
- Consider muscle relaxants for short-term use if spasm present 4
Musculoskeletal Injuries (sprains, strains)
- First-line: Topical NSAIDs with/without menthol gel 1
- Second-line: Oral NSAIDs or acetaminophen 1
- Consider specific acupressure or TENS 1
Dental Pain
Headaches/Migraines
- First-line: NSAIDs or acetaminophen (with/without caffeine) 6
- Avoid opioids and butalbital-containing medications (increased risk of medication overuse headache) 1
Kidney Stone Pain
- NSAIDs or acetaminophen are more effective than opioids 1
Important Considerations and Cautions
NSAID risks: GI bleeding, cardiovascular events, renal effects 2
- Use lowest effective dose for shortest duration
- Higher risk in elderly patients, those on corticosteroids or anticoagulants 7
Acetaminophen risks: Hepatotoxicity at high doses or in patients with liver disease
Muscle relaxant cautions:
- Short-term use only (2-3 weeks maximum)
- May cause sedation, dizziness
- Potential for withdrawal symptoms with abrupt discontinuation 4
When opioids may be appropriate:
Algorithm for Acute Pain Management
- Assess pain type and severity
- For mild to moderate musculoskeletal pain:
- Start with topical NSAIDs (±menthol gel) for accessible areas
- Add oral NSAIDs or acetaminophen if needed
- For moderate pain or if first-line ineffective:
- Combine oral NSAIDs and acetaminophen
- Consider adding short-term muscle relaxant if muscle spasm present
- For severe pain:
- Maximize non-opioid options first
- Consider brief course of opioids only if non-opioid options inadequate AND pain is from severe trauma or invasive surgery
- Use lowest effective dose for shortest duration possible
Research shows the combination of ibuprofen and acetaminophen may be as effective as opioid/acetaminophen combinations for acute extremity pain, with fewer risks 5.
