Never heard this before. My son has asthma and i was told to never use it near him. It makes it worse.
Im 37 weeks pregnant and I used vics on my early 20s weeks of being pregnant. I put it on my chest had a bad cold everything looks good with baby.
Gosh..did you know you aren't supposed to use on babies either because it could cause respiratory issues..yeah the things we learn!
But if youre super worried i would just call your doctors office and ask over the phone theyll tell you. But what i read is that you can use it
I googled it and vics is safe while pregnant
