Safety/Monitoring .
Monitoring Parameters
Cr at baseline, then if renal or hepatic impairment, CHF, dehydration, or hypovolemia cont. periodically; BP during tx start, then periodically; CBC, chemistry profile if long-term tx
Look/Sound-Alike Drug Names
oxaprozin confused with: OXcarbazepine; oxybutynin
Pregnancy/Lactation .
Pregnancy
Clinical Summary
weigh risk/benefit if <30 wk gestation, esp. at 20-29 wk gestation, avoid use starting at 30 wk gestation; if must use at 20-29 wk gestation, limit dose and duration, and consider monitoring amniotic fluid if use >48h; risk of embryo-fetal toxicity and death low in 1st trimester based on conflicting human data; risk of fetal harm, incl. renal dysfxn and oligohydramnios, starting at 20 wk gestation and premature ductus arteriosus closure, starting at 30 wk gestation, based on human data w/ NSAID class and drug's mechanism of action
Individuals of Reproductive Potential
weigh risk/benefit in female pts trying to conceive, esp. if long-term use; NSAIDs may reversibly delay ovulation during tx based on limited human or animal data and drug's mechanism of action
Lactation
Clinical Summary
weigh risk/benefit while breastfeeding, consider short-acting NSAID; no human data available to assess risk of infant harm or effects on milk production
