Difenac 75 SR NF Pregnancy |
||
Difenac 75 SR NF crosses the placenta. Birth defects have been observed following in utero NSAID exposure in some studies; however, data is conflicting (Bloor 2013). Nonteratogenic effects, including prenatal constriction of the ductus arteriosus, persistent pulmonary hypertension of the newborn, oligohydramnios, necrotizing enterocolitis, renal dysfunction or failure, and intracranial hemorrhage have been observed in the fetus/neonate following in utero NSAID exposure. In addition, nonclosure of the ductus arteriosus postnatally may occur and be resistant to medical management (Bermas 2014; Bloor 2013). Because they may cause premature closure of the ductus arteriosus, product labeling for Difenac 75 SR NF specifically states use should be avoided starting at 30 weeks' gestation.
Use of NSAIDs can be considered for the treatment of mild rheumatoid arthritis flares in pregnant women; however, use should be minimized or avoided early and late in pregnancy (Bermas 2014; Saavedra Salinas 2015). If treatment of migraine is needed in pregnant women, agents other than Difenac 75 SR NF are preferred (Amundsen 2015).
Use is not recommended Excreted into human milk: Yes The effects in the nursing infant are unknown.
The data on excretion into breast milk is limited. One women receiving 150 mg daily had milk levels of 100 mcg/L, equivalent to an infant dose of about 0.03 mg/kg/day. Six mothers receiving 100 mg orally daily for 1 week postpartum had undetectable levels in their milk. While it does appear to pass in small amounts, some experts consider this drug to be acceptable during breast feeding, however other agents have more published information and may be preferred, especially when nursing a newborn or preterm infant.
