Why is this medication prescribed?

Transdermal scopolamine is commonly prescribed for the prevention of nausea and vomiting, particularly associated with motion sickness and post-operative nausea. It belongs to a class of medications known as anticholinergics, which work by blocking the action of acetylcholine, a neurotransmitter involved in nausea and vomiting.

How should this medicine be used?

Here’s how transdermal scopolamine is typically used:

• Patch Application: Transdermal scopolamine is administered through a patch that is applied to the skin behind the ear. The patch slowly releases scopolamine into the bloodstream over a period of several days.
• Timing: It is often recommended to apply the patch at least several hours before the anticipated onset of nausea or motion sickness. For instance, if someone is going on a long car ride or cruise, they might apply the patch several hours before departure.
• Dosage: The dosage and frequency of application depend on the individual’s medical condition and response to treatment. It’s important to follow the dosage instructions provided by the healthcare provider or on the medication label.
• Patch Duration: The patch is typically worn for up to three days, after which it should be removed and replaced with a new one if necessary. Patches are usually waterproof, but it’s essential to follow any specific instructions provided with the patch regarding activities like swimming or showering.
• Avoiding Contact with Eyes and Nose: It’s crucial to wash hands thoroughly after applying the patch to avoid accidentally transferring the medication to the eyes or nose, as this can cause irritation.
• Adverse Effects and Precautions: While transdermal scopolamine can be effective in preventing nausea and vomiting, it may cause side effects such as dry mouth, blurred vision, drowsiness, and constipation. Individuals with certain medical conditions or taking specific medications should consult their healthcare provider before using transdermal scopolamine.

As with any medication, it’s essential to use transdermal scopolamine exactly as prescribed by a healthcare professional and to report any adverse effects or concerns promptly.

• Secretory Conditions: In certain cases, transdermal scopolamine might be used to reduce excessive saliva production or sweating (hyperhidrosis).
