Specific Fesoterodine Warnings and Precautions

Warnings and precautions to be aware of prior to taking this medication include the following:
  • In rare cases, this medication can cause life-threatening swelling of the face, lips, tongue, or throat. This can occur quickly, even after the first dose. Seek immediate medical attention if such swelling occurs.


  • Medications like fesoterodine can cause blurred vision, dizziness, and drowsiness. Be sure to see how fesoterodine affects you before driving or operating heavy machinery.
  • This medication may make glaucoma worse. If you have glaucoma and take fesoterodine, your healthcare provider may need to monitor you more closely.
  • Fesoterodine can slow 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 and kidneys help to remove fesoterodine from your body. If you have kidney disease, a lower fesoterodine dosage may be recommended. If you have liver disease, you may require extra monitoring by your healthcare provider. This medication is not recommended for people with severe liver problems.
  • Fesoterodine can decrease your ability to sweat, which may increase your risk of heat stroke. Be sure to stay well hydrated in the heat.
  • This medication may worsen myasthenia gravis. Check with your healthcare provider before taking fesoterodine if you have myasthenia gravis.
  • Fesoterodine may potentially interact with a number of other medications (see Drug Interactions With Fesoterodine).
  • Fesoterodine 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 Toviaz and Pregnancy).
  • It is not known whether fesoterodine 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 Toviaz and Breastfeeding).
