If a transdermal patch falls off, what is the recommended next step?

• A. Reapply a new patch immediately on the old site
• B. Contact a healthcare professional before re-administering a new patch, and discard the old patch
• C. Place a new patch over the old one
• D. Ignore and continue without patch

Answer: (B)

Transdermal patches deliver a fixed amount of medication over time, so any interruption in dosing needs careful handling. When a patch falls off, there’s a risk of underdosing if you just wait or reapply blindly. At the same time, applying a new patch without guidance could result in too much drug being absorbed if there’s still residual medication or overlap from the old patch. That’s why the safest step is to contact a healthcare professional before putting on a replacement patch and to discard the old one. A clinician can confirm whether and when to reapply, and ensure the dosing schedule remains appropriate. Discarding the old patch also prevents confusion about dosing and reduces the chance that someone else handles it and is exposed to the medication. Follow any specific product instructions for site rotation and disposal as well.
