Naproxen/diphenhydramine

Naproxen/diphenhydramine (trade name Aleve PM) is a formulation of naproxen with diphenhydramine marketed by Bayer Healthcare.^[1] It is made as an over-the-counter drug. The intended use of the drug is relieve pain specifically when going to sleep.^[2]

Women in the third trimester of pregnancy should avoid this drug because there is a risk that naproxen, like other NSAIDs, may cause premature closure of the ductus arteriosus.^[2]

In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid.^[3][4] They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy.^[3][4]
