What if the skin shows redness around the patch?

This is a rare instance, but in case your skin shows redness and/or you feel an itching sensation at the site of patch application, it should subside in a few hours.
If the skin redness / irritation continues after six hours, remove the patch and wash the site of application with water. Try another site of application the next day. If similar uncomfortable situation arises, consult your doctor.
