Naproxen (Aleve) Prgnancy Riiskc Category: C (D in 3rd Trimester)

  • Naproxen crosses over the placenta.
  • Some studies have shown that birth defects can be caused by in utero NSAID use.
  • The data are however contradictory.
  • Following in utero NSAID use, nonteratogenic effects such as prenatal constriction, persistent pulmonary hypertension, oligohydramnios and necrotizing enterocolitis have been seen in the fetus/neonate.
  • Additionally, postnatal nonclosure of ductus arteriosus may occur and be resistant to medical treatment.
  • Because NSAIDs can cause premature closure of ductus arteriosus, naproxen's product label specifically states that you should avoid using it starting at 30 weeks gestation.
  • Pregnant women may be able to use NSAIDs for mild rheumatoid-arthritis flares.
  • It should be avoided or minimized during pregnancy.
  • Women of reproductive age who have been using NSAIDs for a long time may experience infertility. This can be reversed by stopping the medication.
  • Women who have difficulty conceiving or are undergoing fertility treatment should consider quitting.
  • The possibility of miscarriage may increase if NSAIDs are used close to the time of conception.

Naproxen use during breastfeeding:

  • Breast milk contains Naproxen.
  • The naproxen relative infant dose (RID) is 3.3%. This was computed using the maximum amount of breast milk concentration and compared to a daily dose of 750 mg for the mother.
  • When the RID is less than 10%, breastfeeding is acceptable.
  • The highest possible milk concentration (2.37 mg/mL) is used to calculate the infant's daily dose of breast milk. It is 0.36mg/kg/day.
  • Following maternal administration of oral naproxen (375 mg twice daily), the milk concentration was assessed.
  • The urine of the infant who was breastfeeding contained Naproxen (Jamali 1982; Jamali83).
  • In a study that included 20 mothers-infant couples, there were two cases each of drowsiness or vomiting among breastfed infants.
  • Postpartum women who want to breastfeed may use NSAIDs.
  • Other agents may be preferable, but women who breastfeed infants with platelet dysfunction and thrombocytopenia should avoid them.
  • Naproxen can be used for short-term (1 week) when needed.
  • Because naproxen has a lower risk profile, other agents are better for migraine treatment in breastfeeding women (Amundsen 2015).
  • According to the manufacturer, when deciding whether to breastfeed during therapy, you should consider the risks to infants, the benefits to breastfeeding for the mother, and the benefits to the mother.

Naproxen (Aleve) Dose in Kidney Disease:

  • CrCl ≥30 mL/min:

      • Temporarily discontinue in patients with intercurrent disease that increases the risk of acute kidney injury.
    • eGFR <30 mL/minute/1.73 m :
      • Avoid use.
