    Pregnancy and Lactation


    Tolterodine is contraindicated during pregnancy.

    The manufacturer does not recommend using tolterodine during pregnancy. There is no adequate information from the use of this agent in human pregnancy. The potential risk is unknown. It is not known if tolterodine or its active metabolite crosses the human placenta. Tolterodine molecular weight indicates such possibility.

    The limited animal data suggest low risk although, studies in animals have shown reproductive toxicity.

    The safest course is to avoid the first trimester, but the risk in early pregnancy appears to be low (Briggs 2015).


    Tolterodine is contraindicated in breastfeeding.

    Manufacturer advises to avoid during lactation. No information is available on the use of this agent during breastfeeding.

    LactMed (2018) indicates that long-term use of tolterodine might reduce milk production or milk let-down therefore, sings of decrease lactation (like insatiety and poor weight gain) should be observed.
