Fertility: There are no data on the effect of flavoxate in human fertility. Flavoxate has no effect on animal fertility.
Pregnancy: There are no or limited amount of data from the use of flavoxate in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see Pharmacology: Toxicology: Preclinical safety data under Actions). As a precautionary measure, it is preferable to avoid the use of Urispas during pregnancy.
Lactation: It is unknown whether flavoxate (metabolites) is excreted in human milk. A risk to the suckling child cannot be excluded. Urispas should not be used during breast-feeding.
