Scopolamine may increase the effects of other drugs that cause drowsiness, including antidepressants, alcohol, antihistamines (including meclizine), sedatives (used to treat insomnia), pain relievers, anxiety medicines, and muscle relaxants. Tell your doctor about all medicines that you are using, and do not use any other prescription or over-the-counter medicines without first talking to your doctor.

Drugs other than those listed here may also interact with scopolamine. Talk to your doctor and pharmacist before using any prescription or over-the-counter medicines.

Stop using scopolamine and seek emergency medical attention or contact your doctor immediately if you experience:

• an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives);

• pain and redness of the eyes with dilated pupils; or

• difficulty urinating.

In rare cases, unusual reactions to ordinary doses of scopolamine have occurred including confusion, agitation, rambling speech, hallucinations, paranoid behaviors, and delusions. In the case of such a reaction, stop using scopolamine and seek medical attention.

Other, less serious side effects may be more likely to occur. Continue to use scopolamine and talk to your doctor if you experience

• drowsiness;

• dizziness;

• dry mouth;

• restlessness;

• blurred vision;

• dilated pupils;

• dry or itchy eyes;

• flushing; or

• fast heartbeats.

Nausea, vomiting, dizziness, headache, and poor coordination have been reported when treatment that has lasted more than a few days is discontinued. If you use scopolamine for more than a few days, be aware that these side effects may occur when you stop.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
