Key value for chemical safety assessment
Effects on fertility
Description of key information
Some small clinical studies suggest that desipramine and other tricyclic antidepressants may reduce libido and cause erectile and ejaculatory dysfunction in males. Other reports have also associated desipramine with testicular pain and swelling.

Effects on developmental toxicity
Description of key information
Based on experimental animal studies and human experience with imipramine, desipramine is not expected to increase the risk of congenital malformations. Desipramine (Norpramin; Pertofrane) is an active metabolite of imipramine.
Neonatal complications have been reported in newborns who were exposed to desipramine in utero. The symptoms observed during the first neonatal month have included colic, cyanosis, rapid breathing, and irritability. The pediatrician can be advised in advance that the mother has been taking this drug. Also, nortriptyline, a congener of desipramine, was associated with urinary retention in one newborn.

Toxicity to reproduction: other studies
Description of key information
Desipramine enters human milk. Maternal and infant serum levels of desipramine and its metabolite 2-hydroxydesipramine were measured in an exclusively breastfed infant after one week of maternal treatment with high-dose desipramine (300 mg/d). Neither desipramine nor its metabolite were detected using cutoffs of 1 ng/mL and 5 ng/mL respectively. No signs of infant toxicity were observed during 3 weeks of maternal treatment.
Desipramine concentrations were reported as undetectable (<25 ng/mL) in 3 infants exposed during pregnancy and lactation to maternal doses of 150-200 mg/d, measured at 2.3-14.9 weeks of age.
An exclusively breastfed infant was exposed beginning at 16 weeks postpartum, for a total of 8 weeks, to maternal treatment with desipramine 100 mg/d. Development was normal at 3 years of age. The clinical significance of low levels of desipramine in the breastfed newborn is not well defined, so observation for possible behavioral effects has been recommended. The American Academy of Pediatrics categorized the effects of desipramine on the nursing infant to be "unknown but a possible cause for concern". In contrast, however, the WHO Working Group on Human Lactation assessed the use of desipramine during lactation as "probably safe," although they noted the need for more data to delineate the range of drug concentrations that may be found in milk.

Justification for classification or non-classification
Overall, available data are inconclusive for the classification of the substance.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
