I wore the patch for about 5 hours I guess and have to take off due to side effects. How long afterwards will I have them? My heart is pounding

Side effects. what type of patch?? nicotine patch? - pain patch or birth control patch? - generally side effects from the patch begin to subside immediately as you have removed the source of medication from your body. It may take up to 12 hours for the effects to wear off. I would recommend drinking plenty of fluids and washing the area of the patch.
