NSAIDs are not recommended during pregnancy, particularly during the third trimester . While NSAIDs as a class are not direct teratogens , they may cause premature closure of the fetal ductus arteriosus and kidney ADRs in the fetus. Additionally, they are linked with premature birth  and miscarriage .   Aspirin, however, is used together with heparin in pregnant women with antiphospholipid antibodies .  Additionally, indomethacin is used in pregnancy to treat polyhydramnios by reducing fetal urine production via inhibiting fetal kidney blood flow.

Prescription NSAIDs are an important treatment for the symptoms of many debilitating conditions, including osteoarthritis, rheumatoid arthritis, gout and other rheumatological and painful conditions. OTC NSAIDs are used to temporarily reduce fever and to treat minor aches and pains such as headaches, toothaches, backaches, muscular aches, tendonitis, strains, sprains and menstrual cramps. Common OTC NSAIDs include ibuprofen (Motrin, Advil) and naproxen (Aleve). In addition, some combination medicines that relieve various symptoms, such as multi-symptom cold products, contain NSAIDs.
