The Basics
What is Clomipramine?
Tricyclic antidepressant that is used to treat symptoms of obsessive-compulsive disorder (OCD), such as recurrent thoughts or feelings and repetitive actions.
Brand names for Clomipramine
Anafranil
How Clomipramine is classified
Antidepressive Agents, Antidepressive Agents (Tricyclic)
Clomipramine During Pregnancy
Clomipramine pregnancy category
Category CNote 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 Clomipramine while pregnant
No teratogenic effects were observed in studies performed in rats and mice at doses up to 100 mg/kg, which is 24 times the maximum recommended human daily dose (MRHD) on a mg/kg basis and 4 times (rats) and 2 times (mice) the MRHD on a mg/m² basis. Slight nonspecific embryo/fetotoxic effects were seen in the offspring of treated rats given 50 and 100 mg/kg and of treated mice given 100 mg/kg. There are no adequate or well-controlled studies in pregnant women. Withdrawal symptoms, including jitteriness, tremor, and seizures, have been reported in neonates whose mothers had taken Anafranil until delivery. Anafranil should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Taking Clomipramine While Breastfeeding
What are recommendations for lactation if you're taking Clomipramine?
Limited evidence indicates that use of clomipramine during breastfeeding is acceptable. For women who were taking clomipramine during pregnancy, the amount of drug in breastmilk may be insufficient to prevent neonatal withdrawal symptoms in breastfed infants. For use as an antidepressant, clomipramine may be less desirable than other antidepressants that have been studied more thoroughly.
Maternal / infant drug levels
Limited evidence indicates that use of clomipramine during breastfeeding is acceptable. For women who were taking clomipramine during pregnancy, the amount of drug in breastmilk may be insufficient to prevent neonatal withdrawal symptoms in breastfed infants. For use as an antidepressant, clomipramine may be less desirable than other antidepressants that have been studied more thoroughly.
Possible effects of Clomipramine on milk supply
Clomipramine has caused increased prolactin levels and galactorrhea in nonpregnant, nonnursing patients.[9][10][11][12] The clinical relevance of these findings in nursing mothers is not known. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
An observational study looked at outcomes of 2859 women who took an antidepressant during the 2 years prior to pregnancy. Compared to women who did not take an antidepressant during pregnancy, mothers who took an antidepressant during all 3 trimesters of pregnancy were 37% less likely to be breastfeeding upon hospital discharge. Mothers who took an antidepressant only during the third trimester were 75% less likely to be breastfeeding at discharge. Those who took an antidepressant only during the first and second trimesters did not have a reduced likelihood of breastfeeding at discharge.[13] The antidepressants used by the mothers were not specified.
A retrospective cohort study of hospital electronic medical records from 2001 to 2008 compared women who had been dispensed an antidepressant during late gestation (n = 575) to those who had a psychiatric illness but did not receive an antidepressant (n = 1552) and mothers who did not have a psychiatric diagnosis (n = 30,535). Women who received an antidepressant were 37% less likely to be breastfeeding at discharge than women without a psychiatric diagnosis, but no less likely to be breastfeeding than untreated mothers with a psychiatric diagnosis.[14] None of the mothers were taking clomipramine.
Possible alternatives to Clomipramine
Fluvoxamine, Nortriptyline, Paroxetine, Sertraline.
