Specific Precautions and Warnings With Darifenacin

Warnings and precautions to be aware of prior to taking darifenacin include the following:
 
  • This medication may make glaucoma worse. If you have glaucoma and take darifenacin, your healthcare provider may need to monitor you more closely.
     
  • Darifenacin can slow down the digestive system. This can cause problems, especially for people who already have a slow digestive system due to myasthenia gravis, ulcerative colitis, or other problems.
     
  • The liver helps to remove darifenacin from your body. Therefore, if you have liver disease, you may require extra monitoring by your healthcare provider and may need to take a lower darifenacin dosage.
     
  • Darifenacin can cause blurred vision, dizziness, and drowsiness. Be sure that you know how the medication affects you before driving or operating heavy machinery.
     
  • Darifenacin can decrease your ability to sweat, which may increase your risk of heat stroke. Be sure to stay well hydrated in the heat.
     
  • Darifenacin may potentially interact with a number of other medications (see Drug Interactions With Darifenacin).
     
  • Darifenacin is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known (see Enablex and Pregnancy).
     
  • It is not known whether darifenacin passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Enablex and Breastfeeding).
