Q. My nose gets terribly dry in the winter and I frequently get nosebleeds. I used to use Vicks VapoRub to moisturize it but read in your column this is a bad idea. My doctor told me to use K-Y Jelly, and it works great to prevent nosebleeds.
A. Pulmonologists have warned against using petroleum jelly in the nostrils since such products may be bad for the lungs. K-Y Jelly is a water-based sexual lubricant, so the risk is much lower. Saline nasal sprays may also help moisten dry nasal tissues.
