Methscopolamine can cause side effects that may impair your vision, thinking, or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
Cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by methscopolamine. Tell your doctor if you regularly use any of these medicines.
Avoid drinking alcohol. It can increase some of the side effects of methscopolamine.
