Transderm Scop (Scopolamine) - Transdermal

Additional Content Provided and Reviewed by IBM Micromedex

What Is Transderm Scop?

Transderm Scop (scopolamine) is a prescription transdermal patch placed on the skin to prevent nausea and vomiting due to motion sickness or anesthetic medication. Transdermal patches deliver the medication through the skin.

This medication is called an anticholinergic, meaning it works by blocking the activity of acetylcholine, a neurotransmitter that has many actions in the central nervous system (CNS, brain and spinal cord) and the peripheral nervous system (nerves of the organs and the skeletal muscles). These actions cause the Transderm Scop patch to have a range of effects, such as dilating (expanding) the pupils, inhibiting saliva and sweat, decreasing gastrointestinal (GI) activity, and increasing heart rate.

What Is Transderm Scop Used For?

The Food and Drug Administration (FDA) approved Transderm Scop for use in adults as a preventative medication before anticipated nausea and vomiting due to a particular reason.

Transderm Scop is indicated to prevent:

  • Nausea and vomiting associated with motion sickness 
  • Postoperative nausea and vomiting that can occur with recovery from anesthesia, opiates, and surgery

How to Use Transderm Scop

Use the Transderm Scop patch as directed by your healthcare provider.

For preventing symptoms of motion sickness, place the patch at least four hours before you want it to work.

For preventing symptoms after surgery and anesthesia, place the patch the night before your surgery and remove it 24 hours after your procedure.

The patch should be placed on the hairless skin behind your ear. Make sure the area is dry before applying it. Wash your hands immediately after you touch the patch to avoid getting medication in your eyes, mouth, or anywhere else.

Wear one patch at a time, and do not cut it. If the patch moves out of place, remove it and replace it on the same spot on your skin. If you need to use this medication for longer than three days, remove the used patch and replace it with a new one.

If you need a dose of less than a single patch, you can remove only a portion of the patch backing and apply it with only a portion of the patch making contact with the skin. You must still wear this portion of the patch for three days at a time. For example, if you need a half dose of the patch, remove only a half of the patch backing and expose only half of the patch adhesive to the skin. After applying, cover the patch with an adhesive dressing to ensure stability.

Discard the used patch carefully, folding in the medicated side and ensuring that children or pets can’t get access to it.


Store this medication out of reach from pets or children. Store it in an upright position, and don’t let the pouches get bent or rolled. 

Keep Transderm Scop patches at room temperature, between 68 F and 77 F.

Off-Label Uses

Healthcare providers sometimes prescribe Transderm Scop off-label for other medical uses not specified by the FDA.

Because of its ability to inhibit the action of acetylcholine, Transderm Scop has off-label uses for treating or preventing:

Although it is approved for adults, children are sometimes prescribed Transderm Scop off-label. If you are prescribed this medication for an off-label indication, use it as directed by your provider and make sure you are aware of the potential side effects.

Transderm Scop is approved for adults, but it is prescribed off-label for adults and children.

How Long Does Transderm Scop Take to Work?

Transderm Scop begins to work within a few hours. Take it hours before anticipated nausea and vomiting are expected to begin.

What Are the Side Effects of Transderm Scop?

This is not a complete list of side effects and others may occur. A medical professional can advise you on side effects. If you experience other effects, contact your pharmacist or a medical professional. You may report side effects to the FDA at or 1-800-FDA-1088.

The side effects of Transderm Scop are caused by its anticholinergic activity. Most side effects are mild and temporary, but severe side effects can be life-threatening and may require urgent treatment.

Overdose: What Happens If I Take Too Much Transderm Scop?

Placing more than one patch on the body or ingesting Transderm Scop patches can cause anticholinergic toxicity. You are also at risk of toxicity if you have underlying health problems, are 65 years of age or older, or have low body weight.

Effects of an overdose can include:

  • Dry skin and/or dry mouth
  • Extreme tiredness
  • Confusion
  • Agitation
  • Hypertension (high blood pressure)
  • Urinary retention (inability to urinate)
  • GI blockage
  • Irregular heart rate
  • Hallucinations
  • Seizures
  • Vision changes
  • Coma

These effects can be dangerous and require close observation with monitoring of vital signs. Symptomatic medical treatment is sometimes necessary. Your healthcare provider may need to provide you with respiratory support as the medication is wearing off. 

The effects of Transderm Scop toxicity can be similar to some of the symptoms of drug withdrawal.
