Is using Vicks Vapor Inhaler during pregnancy dangerous?

If the doctor knows about it I wouldn't worry! Just let him know you have been needing to use it! If he doesn't want you to use that the doctor will tell you something else that can be used! I have bad asthma and allergies and have had to use allergy and asthma medicines to control it so I can breath! The doctor said in my case they are more worried about me not being able to breath and deprive baby of vital oxygen then the inhalers! That is the most important thing for you to do is to fallow your doctors directions and if he/she said it would be fine then you should be ok! Good luck!
