Category XNote that the FDA has deprecated the use of pregnancy categories, so for some medications, this information isn’t available. We still think it’s useful to list historical info, however, given what a common proxy this has been in the past.
What we know about taking Temazepam while pregnant
Restoril is contraindicated in women who are or may become pregnant. If this drug is usedduring pregnancy, or if the patient becomes pregnant while taking this drug, the patient should beapprised of the potential hazard to the fetus. Patients should be instructed to discontinue the drugprior to becoming pregnant. The possibility that a woman of childbearing potential may bepregnant at the time of institution of therapy should be considered. Reproduction studies in animals with temazepam were performed in rats and rabbits. In aperinatal-postnatal study in rats, oral doses of 60 mg/kg/day resulted in increasing nurslingmortality. Teratology studies in rats demonstrated increased fetal resorptions at doses of 30 and120 mg/kg in one study and increased occurrence of rudimentary ribs, which are consideredskeletal variants, in a second study at doses of 240 mg/kg or higher. In rabbits, occasionalabnormalities such as exencephaly and fusion or asymmetry of ribs were reported without doserelationship. Although these abnormalities were not found in the concurrent control group, theyhave been reported to occur randomly in historical controls. At doses of 40 mg/kg or higher,there was an increased incidence of the 13th rib variant when compared to the incidence inconcurrent and historical controls.
Taking Temazepam While Breastfeeding
What are recommendations for lactation if you're taking Temazepam?
Because of the low levels of temazepam in breastmilk and its relatively short half-life, amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants. Taking the bedtime dose after the infant’s last feeding of the day may minimize the dose received by an older infant who is sleeping through the night.
