Which medication should be given before intrauterine device (IUD) insertion to reduce pain?

Medication for Pain Management Prior to IUD Insertion

The expert recommendation is to give prescription-strength oral naproxen 550 mg taken 1-2 hours before IUD insertion, or alternatively ketorolac (20 mg oral or 30 mg intramuscular) given 1-2 hours prior to the procedure. 1

Primary Analgesic Recommendations

First-Line: NSAIDs

The 2025 American Journal of Obstetrics and Gynecology best practices guideline provides clear direction on systemic analgesia:

• Naproxen 550 mg orally 1-2 hours before insertion is the preferred first-line option 1

  • Demonstrated reduction in pain during IUD placement in multiparous patients
  • Showed clinically significant reduction in pain at 5 and 15 minutes post-insertion in nulliparous patients
  • More effective than standard ibuprofen dosing

• Ketorolac as an alternative:

  • 20 mg oral, taken 40-60 minutes before insertion: reduced pain during and 10 minutes after placement 1
  • 30 mg intramuscular, given 30 minutes prior: reduced pain at 5 and 15 minutes after placement (though not during insertion) 1

Important caveat: Standard-dose ibuprofen taken as single-dose premedication has NOT been shown to reduce pain during IUD placement 1. However, recent 2026 research on multidose ibuprofen (800 mg × 3 doses over 24 hours before insertion) did show significant pain reduction 2, though this is not yet incorporated into standard guidelines and requires more planning.

Second-Line: Opioid Option

• Tramadol 50 mg orally 1 hour prior to insertion 1
  • Significantly decreased pain compared to placebo
  • More effective than naproxen in one study
  • Critical restrictions: Cannot be given with benzodiazepines; patient needs transportation to/from appointment
  • Reserve for patients with anticipated severe pain or high anxiety

Local Anesthesia Options

When systemic analgesia alone may be insufficient, local anesthesia should be considered:

Intracervical Block (ICB)

The guideline now recommends ICB as an alternative to paracervical block 1:

• 2% lidocaine 3.6-4 mL injected intracervically at 3,6,9, and 12 o'clock positions before tenaculum placement 1
• Alternative: 1% lidocaine with standard syringe if 2% unavailable 1
• More effective than naproxen 550 mg alone for reducing insertion pain 1
• No wait time required after injection 1

Topical Anesthetics

• EMLA cream 4-5 g applied to cervix and cervical canal 1
• 10% lidocaine spray to cervix 1
• Require 5-10 minute wait time depending on type 1

Paracervical Block (PCB)

• 2 mL buffered 1% lidocaine at tenaculum site, then remaining anesthetic at 4 and 8 o'clock positions at cervicovaginal junction 1
• More invasive but highly effective
• No wait time needed after injection 1

Anxiolytics for High-Anxiety Patients

While benzodiazepines don't directly reduce pain, they can improve the overall experience:

• Oral midazolam 10 mg taken 30-60 minutes beforehand (preferred due to fast onset, short half-life 1.5-2.5 hours) 1
• Alternatives: lorazepam 1-2 mg sublingual or diazepam 5-10 mg oral, 20-30 minutes before 1
• Cannot be combined with tramadol 1
• Patient requires transportation

What NOT to Use Routinely

Misoprostol

Do NOT use routinely for pain control 1:

• Most studies do not support routine use for decreasing pain
• Increases postprocedure cramping
• Reserve ONLY for: previous failed insertion attempts or known cervical stenosis 1
• If used: 400 mcg vaginally 4 hours prior 1

Standard-Dose Ibuprofen

• Single-dose ibuprofen premedication has not been shown to reduce pain during insertion 1
• May help with post-procedure pain only (peak levels occur 1-2 hours after administration) 1

Practical Algorithm

For routine IUD insertion:

1. Prescribe naproxen 550 mg to take 1-2 hours before appointment
2. Consider adding topical lidocaine or ICB at time of procedure based on patient preference and nulliparity

For nulliparous patients or those with high anxiety:

1. Naproxen 550 mg 1-2 hours before
2. ICB with 2% lidocaine at procedure
3. Consider midazolam 10 mg 30-60 minutes before if significant anxiety

For patients with previous difficult/failed insertion:

1. Naproxen 550 mg 1-2 hours before
2. Consider misoprostol 400 mcg vaginally 4 hours prior (accept increased cramping as trade-off)
3. ICB or PCB at procedure
4. Ultrasound guidance

For patients with severe anticipated pain:

1. Tramadol 50 mg 1 hour before (arrange transportation)
2. ICB or PCB at procedure
3. Do NOT add benzodiazepine if using tramadol

Common Pitfalls

• Timing matters: NSAIDs must be given 1-2 hours before, not at time of procedure
• Don't rely on ibuprofen alone: Standard single-dose ibuprofen is ineffective for procedural pain
• Warn about lidocaine side effects: Numbness of tongue, tinnitus are self-limiting 1
• Don't combine tramadol with benzodiazepines: Respiratory depression risk 1
• Misoprostol is not a pain medication: It's for cervical dilation in select cases only, and increases cramping 1
