The Effects of Ibuprofen Consumption on the Incidence of Postpartum Depression

Postpartum depression (PPD) is a common and debilitating psychiatric condition whose etiology is yet to be fully elucidated. Anti-inflammatory medications have been shown to be effective in the treatment of major depressive disorder but there have only been a few trials examining whether anti-inflammatory medications can serve as effective prophylactic agents against the development of major depressive disorder. Prophylaxis against PPD with anti-inflammatory agents has never been studied.

We performed a prospective observational trial examining whether consumption of higher doses of the nonsteroidal anti-inflammatory drug ibuprofen is associated with a lower incidence of PPD. We recruited high-risk women and collected data on Edinburgh Postnatal Depression Scale, Patient-Reported Outcome Measurement Information System pain scale and clinical assessment of PPD at postpartum weeks 0, 3, and 6. Subjects were instructed to keep a log of medication consumed.

When looking at the total sample, we found that higher consumption of ibuprofen was associated with lower incidence of PPD, although this result was nonsignificant (P = 0.26). When we stratified by concurrent psychotropic medication, we found that among women not taking psychotropic medications, higher consumption of ibuprofen at week 3 was significantly associated with a lower likelihood of having PPD at week 3 (P = 0.03).

We found that ibuprofen consumption was significantly associated with a reduced risk of development of PPD at week 3 among high-risk women not taking psychotropic medications.
