Some medicines are not so safe during pregnancy
. But, sometimes the risk of not taking them is worse than taking them. I have seasonal asthma/ allergies. I have been on my inhaler, sinus meds, and 2 rounds of antibiotics in the past 2 weeks.when having respiratory problems such as asthma, when an attack happens it usually causes a fast raipid heartbeat and anxiety. This is not good for the baby. That is why a breathing treatment with the machine is a last resort.
