If you miss a dose of this medication, take it as soon as possible. If, however, it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double dose.
Tolterodine may cause dizziness or drowsiness; use caution when driving or doing any activities that require alertness.
Tolterodine may cause drying of the mouth. Since continued dryness of the mouth can increase the risk of dental disease, alert your dentist if you are taking this medication.
This medication may interact with fluoxetine (Prozac) in such a way as to increase the effect of the tolterodine. If you are taking fluoxetine, your physician may start you at a lower dose of tolterodine, gradually raising it to the standard dose if necessary.
This medication has not been studied in pregnant women. However, it has been shown in animal studies to result in increased embryo deaths, reduced birth weight, and increased incidence of fetal abnormalities. If you are pregnant, or planning to become pregnant, do not start this medication before you have discussed it with your physician.
It is not known whether tolterodine passes into breast milk. Since tolterodine is known to pass into the milk of nursing animals, causing temporary reduction in weight gain in the offspring, women should stop taking this drug as long as they are nursing.
