Dealing with a blocked nose can be very uncomfortable, especially during these early weeks. While using a Vicks Inhaler occasionally is generally considered to have low risk because very little medication is absorbed into your body, it contains ingredients like camphor and menthol. During your first trimester, it is always safest to use caution. I highly recommend trying safe, drug-free alternatives first, such as a plain saline nasal spray or steam inhalation. If your congestion is still bothersome, please consult your healthcare provider to ensure the safest care for you and your baby.
