Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

• Constipation (less common with hyoscyamine)
• Decreased sweating
• Dryness of mouth, nose, throat, or skin

• Bloated feeling
• Blurred vision
• Decreased flow of breast milk
• Difficult urination
• Difficulty in swallowing
• Drowsiness (more common with high doses of any of these medicines and with usual doses of scopolamine when given by mouth or by injection)
• False sense of well-being (for scopolamine only)
• Headache
• Increased sensitivity of eyes to light
• Lightheadedness (with injection)
• Loss of memory
• Nausea or vomiting
• Redness or other signs of irritation at place of injection
• Trouble in sleeping (for scopolamine only)
• Unusual tiredness or weakness

• Decreased interest in sexual intercourse
• Inability to have or keep an erection
• Loss in sexual ability, desire, drive, or performance
• Loss of taste

After you stop using scopolamine, your body may need time to adjust. The length of time this takes depends on the amount of scopolamine you were using and how long you used it. During this period of time check with your doctor if you notice any of the following side effects:

• Anxiety
• Irritability
• Nightmares
• Trouble in sleeping

For patients using the transdermal disk of scopolamine:

While using the disk or even after removing it, your eyes may become more sensitive to light than usual. You may also notice the pupil in one eye is larger than the other. Check with your doctor if this side effect continues or is bothersome.

Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
