Warnings and precautions to be aware of prior to taking oxybutynin include the following:
The kidneys and liver help to remove the drug from your body. Therefore, if you have kidney or liver disease, you may require extra monitoring by your healthcare provider and you may need to take a lower oxybutynin dosage.
The medication can cause blurred vision, dizziness, and drowsiness. Make sure you know how oxybutynin affects you before driving or operating heavy machinery.
Oxybutynin is considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the full risks are not known (see Ditropan and Pregnancy).
It is not known if oxybutynin 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 Ditropan and Breastfeeding).
