Proper Use of Scopolamine for Motion Sickness Prevention

The most effective way to use scopolamine for motion sickness prevention is to apply one transdermal patch (1 mg/3 days) to a hairless area behind the ear at least 4 hours before exposure to motion, as it provides up to 72 hours of protection. 1

Application Instructions

• Apply the transdermal patch to a clean, dry, hairless area of skin behind one ear at least 4 hours before anticipated motion exposure 1
• Wash hands thoroughly with soap and water immediately after applying the patch to prevent accidental transfer of medication to eyes 1
• The patch should remain in place for up to 3 days (72 hours) of continuous protection 1, 2
• If protection is needed for longer than 3 days, remove the patch and apply a new one behind the opposite ear 1
• Avoid touching the adhesive surface during application to ensure proper adherence 1

Timing Considerations

• The transdermal patch takes 4-6 hours to reach effective blood levels, so early application before travel is crucial 2
• For immediate protection while waiting for the patch to take effect, consider combining with oral scopolamine (0.3-0.6 mg) under medical supervision 3
• The patch provides continuous protection for up to 72 hours without the need for additional dosing 1, 4

Potential Side Effects and Precautions

• Common side effects include dry mouth, drowsiness, blurred vision, and dizziness 1, 4
• Temporary increase in pupil size and blurry vision may occur, especially if the patch comes in contact with the eyes 1
• Withdrawal symptoms may occur 24+ hours after removing the patch if used for several days, including dizziness, nausea, vomiting, and confusion 1
• The patch should be used with caution in elderly patients and those with pre-existing psychiatric conditions due to increased risk of central nervous system side effects 5
• Hypermetropic ("long-sighted") individuals may be particularly susceptible to visual accommodation problems 4

Proper Removal and Disposal

• After the recommended wear time, remove the patch and wash the application area thoroughly with soap and water 1
• Fold the used patch in half with the sticky sides together before disposal to prevent accidental exposure to others 1
• Dispose of the used patch in household trash out of reach of children and pets 1

Behavioral Strategies to Enhance Effectiveness

• Position yourself in the most stable part of the vehicle (middle of boat, over wings in aircraft) 2
• Focus on the true visual horizon when possible 2
• Consider lying down with eyes closed if symptoms worsen 2
• Minimize other sources of physical, mental, or emotional discomfort during travel 2

Storage Instructions

• Store patches at room temperature between 68°F and 77°F (20°C and 25°C) 1
• Keep patches in an upright position 1
• Do not bend or roll the patches 1
• Keep out of reach of children 1

Scopolamine transdermal patches have been shown to reduce the incidence of motion-induced nausea and vomiting by approximately 75% in clinical studies, making them one of the most effective options for motion sickness prevention 1, 2.
