Use of non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDS) has been associated with an increased risk of miscarriage. This has been hypothesized as being related to prostaglandin levels in the endometrium.


Risk factors for miscarriage:

(1) any non-aspirin NSAID at any dose

(2) NSAID dose around the time of conception

(3) use of NSAID for more than 1 week


Taking an anti-emetic agent during the pregnancy was associated with a reduced risk for miscarriage.


The differential diagnosis would include conditions for which NSAIDS may be given:

(1) rheumatologic disorder

(2) infection
