Scopolamine (Transdermal)

Scopolamine works by restoring the balance of natural substances norepinephrine and acetylcholine that may be upset in motion sickness, as well as by blocking some signals to your brain that may cause vomiting and nausea.

Overview

Motion sickness happens quite often. It can happen when you travel by road, rail, air, or water. It's especially common in kids. It's caused by frequent unusual motions of the head. Motions like going around corners or over bumps send plenty of messages to the brain. The balance systems in the inner ear receive different signals to what your eyes see. This sends confusing messages to your brain, making you nauseous (having a feeling of sickness). Scopolamine prevents the confusing messages from being sent to your brain.

Scopolamine comes in the form of a skin patch known as Transderm Scop for adult use. The patch is stuck on the skin behind the ear four hours before a journey and then removed when the journey ends. Transderm Scop releases Scopolamine through the skin and into the bloodstream.

Scopolamine is also used for preventing vomiting and nausea that may occur post-surgery and when opiate painkillers or anesthetics have been used. Scopolamine should be used 24 hours before surgery and taken off 24 hours post-surgery.

One of the common effects of this skin patch is that it brings on a dry mouth. Sometimes it's prescribed by doctors for this purpose, instead of preventing nausea.

Dosage

  • Apply Scopolamine skin patch to a hairless skin area just behind the ear.
  • Wear only one patch per time. Don't tear or cut the patch.
  • To prevent motion sickness, apply the skin patch at least four hours before you're exposed to what can cause motion sickness.
  • To prevent vomiting and nausea after surgery, apply the patch the night before surgery. Wear the patch for one day after surgery and then discard it.
  • If the patch falls off, get a new one to replace it.
  • You can wear one patch for up to three days. If you need a patch for longer than three 3 days, take off the patch and replace it with a new one just behind the other ear.
  • After taking off a patch, carefully fold it and discard it where your children and pets can't reach it.
  • Always clean your hands with water and soap after handling Scopolamine, whether you're applying the skin patch or taking it off. To ensure there aren't traces of Scopolamine left on the skin after removing a patch, wash the area behind the ear where you wore the patch. Use water and soap and then dry well.

  • If you've forgotten to apply the medication as instructed before surgery, call up your doctor for directions. Don't apply extra patches to compensate for applying the patch later than directed.
