Individuals over the age of 60 can experience an increased sensitivity to this type of medication. This sensitivity can result in more pronounced side effects as well as a higher rate of occurrence. Because these medications can produce drowsiness, dizziness and lightheadedness, older users should be particularly careful when operating a vehicle.

Elderly individuals are also more likely to experience:

• Confusion or memory loss
• Constipation
• Unusual excitement
• Restlessness or irritability

Elderly individuals are at a higher risk of developing glaucoma from this treatment and should immediately contact a physician if they experience any type of eye pain while taking the medication.
