Scopolamine patches are used to help prevent nausea and vomiting. They’re often prescribed if you experience nausea due to medications or motion sickness.

Scopolamine patches are worn behind the ear and can be left in place for up to 3 days. Another patch can be applied after 3 days if you still need nausea prevention.

Scopolamine patches are linked to some side effects. Most side effects are mild and temporary and will usually resolve on their own. However, in rare cases, serious side effects can occur that need urgent medical attention.

Scopolamine patches can cause several side effects. Most side effects are mild and will resolve on their own. Common side effects of the scopolamine patch include:

After you apply a scopolamine patch, it will take your skin at least 4 hours to absorb the medication. This typically means it will take at least 4 hours — and it might take as long as 8 hours — to notice any side effects.

Most side effects will ease after a day or two. However, some side effects may linger even after you remove the patch, as the medication will still be in your bloodstream. It can take a day or more for side effects to resolve after you’ve removed a scopolamine patch.

In rare instances, scopolamine patches may cause severe side effects. Some of these side effects require urgent medical attention.

If you notice any of these side effects, it’s important to remove the patch immediately and get medical attention right away. Serious side effects of the scopolamine patch include:

These side effects are rare. Some have only been reported in a small number of scopolamine patch users. However, because these side effects are serious, it’s important to be aware of them and to tell your doctor right away if you experience any of them.

It’s also important that your doctor knows about any medications, vitamins, and nutritional supplements you take, as these medications could interact with the scopolamine patch and cause side effects.

The best way to minimize possible side effects of the scopolamine patch is to use it exactly as instructed. This can also help you get the best results from the patch.

Once you have the patch in place, be sure to:

  • avoid getting water on the patch
  • apply a new patch if your patch falls off
  • avoid cutting or trimming your patch if it becomes loose
  • wear your patch for exactly as long as prescribed
