Is hand sanitizer safe to use during pregnancy?

What does the evidence say about hand sanitizer during pregnancy?

1. Only about 0.5 to 2.3 percent of the ethanol applied in a hand rub is actually absorbed into the body, and even with repeated hygienic or surgical-level disinfection, the resulting blood alcohol levels stayed far below the concentrations that impair coordination or judgment. 1
2. Alcohol works by denaturing and coagulating proteins in microbes, with 60 to 95 percent concentrations generally effective, and higher concentrations are actually less effective since proteins need some water present to denature; the same review notes that more research is specifically needed on long-term effects for pregnant healthcare workers who use it many times a day. 2
3. A safety assessment modeling ethanol exposure from hand sanitizer found the resulting internal doses carried wide safety margins, roughly 2 to 1000-fold, compared with the exposure levels linked to developmental harm, concluding that even intense, frequent use is not expected to pose a meaningful developmental risk. 3
4. A systematic review of triclosan, an antibacterial ingredient sometimes used in soaps and sanitizers, found no clear association with human infertility overall, though some included studies linked triclosan exposure to changes in semen quality and in ovarian reserve markers, and the authors called the overall evidence base unsettled. 4
5. A meta-analysis of hand hygiene and community infection risk estimated that a single hand hygiene event was associated with roughly a 3 percent drop in the daily probability of catching a respiratory infection, an effect the authors project could scale toward a 15 to 28 percent reduction with several hand hygiene events spread through the day. 5

Is hand sanitizer safe in each trimester?

• First trimester. Nothing about early pregnancy changes how hand sanitizer behaves on your skin. If you're also newly sensitive to strong scents, an unscented or lightly scented formula can make frequent use more tolerable.
• Second trimester. Routine hand sanitizer use alongside regular handwashing is a reasonable way to lower your everyday exposure to cold and flu viruses during this stretch of pregnancy, without any special second-trimester precaution.
• Third trimester. No new precaution applies as you get closer to delivery. If you work in a setting where you're sanitizing dozens of times a shift, that heavier, occupational-level pattern is worth a quick mention at a prenatal visit, since it hasn't been specifically studied in pregnancy.
