Yes, you can sleep with a lidocaine patch, Biofreeze patch, or Icy Hot patch. They are all considered safe for night-time use. It is important to keep in mind that any pain patch should only be limited to less than 12 hours of use, and in some cases up to 8 hours depending on the instructions.

For adults and children over 12 years, apply one Icy Hot® Lidocaine Patch to the affected area for up to 8 hours. Repeat as necessary, but do not use more than 3 to 4 times daily. Use as directed.

For adults and children over 12 years of age, apply a thin layer of Icy Hot® No Mess to affected area and massage until thoroughly absorbed into skin. Repeat as necessary, but no more than 3 to 4 times daily.

However, it's important to understand that there is no “healing” going on from the Icy Hot itself. It does not affect your muscles, nor can it correct any damaged tissues. It simply creates a distraction from your pain, hopefully long enough for your body to initiate a healing process.
