Pregnancy Category

Pregnancy Published literature reports that use of NSAIDs after 30 weeks’ gestation increases risk of premature closure of fetal ductus arteriosus; data from observational studies regarding potential embryofetal risks of NSAID use, including diclofenac, in women in first or second trimester of pregnancy are inconclusive; avoid use of NSAIDs in pregnant women starting at 30 weeks of gestation (third trimester) Infertility Based on mechanism of action, the use of prostaglandin-mediated NSAIDs, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women; published animal studies have shown that administration of prostaglandin synthesis inhibitors has potential to disrupt prostaglandin- mediated follicular rupture required for ovulation; small studies in women treated with NSAIDs have also shown reversible delay in ovulation; consider withdrawal of NSAIDs in women who have difficulties conceiving or who are undergoing investigation of infertility Lactation Data from published literature reports with oral preparations of diclofenac indicate presence of small amounts of diclofenac in human milk; there are no data on effects on breastfed infant, or on milk production; consider developmental and health benefits of breastfeeding along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from treatment or from underlying maternal condition

Increased risk of nephrotoxicity w/ ciclosporin or triamterene. May increase the risk of developing corneal complications in patients w/ significant pre-existing corneal inflammation when use concomitantly w/ ophth preparation containing corticosteroids. Colestyramine and colestipol reduce the bioavailability of diclofenac. Decreased plasma concentration when administered after sucralfate. Ophth application of diclofenac may reduce the efficacy of ophth acetylcholine and carbachol. May increase serum levels of lithium and digoxin.
