Ventolin is completely safe during pregnancy ive been asthmatic all my life and am 20w now I still take my inhaler as and when needed i often use it more frequently now as I get shorter of breath quicker the inhaler opens the airways and lungs to give you and baby oxygen it would be worse not to take it as it deprives baby of the oxygen they need which could cause baby to be born with difficulties
It's taken into your lungs, and if you're an asthmatic, or have pregnancy asthma, you need to take the medication. Ventolin is a steroid to get you coughing up the gunk that is in your lungs from asthma. It goes straight to your lungs and baby will be fine, if you keep breathing.
