Mothers who breastfeed and take antidepressants invited to participate
IOWA CITY, Iowa -- University of Iowa researchers are beginning a clinical
trial to measure antidepressant levels in breastfeeding women who take such
medication and the antidepressant levels in their infants.
Mothers age 18 or older, with infants under 6 months of age, who breastfeed
at least three times a day and take antidepressants are invited to participate
in the study.
Participants will need to make one visit to the UI Hospitals and Clinics,
where they will be asked to provide a breast milk sample and one blood sample.
A small blood sample (less than 1/4 teaspoon) also will need to be collected
from the infant. The test results will be forwarded to the participant and
her designated physician(s). Compensation will be provided.
Although most antidepressants appear in breast milk, blood levels for most
antidepressants have been measured in fewer than two dozen women and their
infants, and some newer drugs have been studied in only a handful of cases
or not at all, said Alicia Weissman, M.D., UI assistant professor of family
medicine and one of the principal investigators for the study.
"Antidepressive medications offer effective treatment for postpartum
depression, which occurs in 10 to 15 percent of women who give birth,"
Weissman said. "However, when the mother is also breastfeeding, the decision
to start medication becomes very difficult."
The study will focus on newer antidepressants that are commonly used as
the first line of treatment in primary care settings: Wellbutrin (buproprion),
Prozac (fluoxetine), Zoloft (sertraline), Paxil (paroxetine), Effexor (venlafaxine),
Luvox (fluvoxamine), Celexa (citalopram), Serzone (nefazodone) and Remeron
Katherine Wisner, M.D., Helen C. Levitt Endowed Visiting Professor at the
UI College of Medicine, is helping Weissman conduct the study.
