Scopolamine is a generic prescription drug that relieves motion sickness and postoperative nausea and vomiting. It belongs to a family of drugs called anticholinergic drugs and works by slowing nerve signals in an area of the brain called the vomiting center. In the U.S., it’s only available as an extended-release skin patch. It can be worn for one to three days and delivers a constant dose through the skin.

  • How to apply a scopolamine patch:

    • Leave the patch in its sealed wrapper until you are ready to put it on. 

    • Select a hairless area of skin behind the ears.

    • Do not put the patch on skin that is cut or tender.

    • Clean and dry the skin.

    • Take the liner off the sticky, metallic side of the patch.

    • Do not touch the metallic, sticky surface of the patch.

    • Place the metallic, sticky surface of the patch to the skin with the tan side of the patch facing outwards.

    • Remove the remaining lining on top of the tan surface.

    • Wash your hands with soap and water.

    • Do not touch the patch again until you are ready to remove it. You may squeeze some of the medicine out of the patch.

    • Limit contact with water while swimming and bathing because the patch may fall off. If the patch is loose or falls off, throw it away and apply a new patch behind the other ear.

  • For postoperative nausea and vomiting, remove the patch 24 hours after it was applied.

  • For motion sickness, the patch can remain in place for up to three days after it was put on.

  • After you take off the patch, wash the skin area where the patch was placed.

  • Fold the used patch in half with the sticky sides together. Throw the used patch away so that children or pets cannot get to it. 

  • Store scopolamine patches at room temperature in an upright position. Do not bend or roll up the patches.
