Pressure Dressing Duration After Contraceptive Implant Placement
Keep the pressure dressing on for 24 hours after contraceptive implant insertion.
Standard Post-Insertion Care
After placement of a subdermal contraceptive implant (Implanon/Nexplanon), the standard recommendation is to maintain a pressure dressing for 24 hours to minimize bruising and ensure proper hemostasis at the insertion site. This is followed by keeping a small adhesive bandage in place for 3-5 days to protect the insertion site.
Rationale and Clinical Context
The insertion procedure itself is quick—taking approximately 1 minute 1—and is performed subdermally in the non-dominant upper arm, 6-8 cm above the elbow 2. The pressure dressing serves to:
- Prevent hematoma formation
- Minimize bruising at the insertion site
- Provide initial wound protection
- Reduce local swelling
Important Post-Procedure Instructions
After the 24-hour pressure dressing period:
- Keep the site dry for the first 24 hours
- Avoid heavy lifting with the affected arm for 24-48 hours
- Leave the small adhesive bandage in place for 3-5 days
- Palpate the implant to confirm proper placement before the patient leaves the clinic
Critical Safety Considerations
While complications are rare, proper insertion technique is essential to prevent serious adverse events. Recent evidence shows that nerve injuries, particularly to the ulnar nerve, can occur especially during removal procedures when implants become impalpable 3. This underscores the importance of:
- Correct initial placement depth (subdermal, not intramuscular)
- Proper anatomical positioning (avoiding the sulcus between biceps and triceps where neurovascular structures lie)
- Patient education about palpating the implant regularly to ensure it remains palpable
The 24-hour pressure dressing is a simple but important step in the immediate post-insertion care protocol that helps ensure optimal healing and reduces minor complications at the insertion site.
