8 Use in Specific Populations

8.1 Pregnancy

(PLLR conversion)

Risk Summary

UROXATRAL is not indicated for use in women.

There are no adequate data on the developmental risk associated with use of UROXATRAL in pregnant women.

Based on findings from animal studies, alfuzosin administered during the period of organogenesis was not teratogenic, embryotoxic or fetotoxic at up to 1200 times the MRHD of 10 mg via AUC in rats and 3 times in rabbits, via body surface area.

In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancy is 2-4% and 15-20%, respectively.

Data

Animal data

Alfuzosin was not teratogenic, embryotoxic or fetotoxic in rats at plasma exposure levels (based on AUC of unbound drug) up to 1200 times (maternal oral dose of 250 mg/kg/day) the maximum recommended human dose (MRHD) of 10 mg.  In rabbits administered up to 3 times the MRHD (based on body surface area) (maternal oral dose of 100 mg/kg/day) no embryofetal toxicity or teratogenicity was observed. Gestation was slightly prolonged in rats at exposure levels (based  on AUC of unbound drug) approximately 12 times (greater than 5 mg/kg/day oral maternal dose) the MRHD, but difficulties with parturition were not observed.

8.2 Lactation

(PLLR conversion)

Risk Summary

UROXATRAL is not indicated for use in women. There are no data on the presence of UROXATRAL in human milk, the effect on the breastfed child, or effect on milk production.
