Mine said non medication saline nose spray, the others could cause problems but just haven't been tested on pregnancy.
In general, actin whether pregnant or not is meant for short term use. It has that rebound effect where people Ned it to feel like they can breathe. My doctor is okay with it for 1 week max.
Yes being a nurse I'm very knowledgeable with medications, but jw what everyone's OB decision is on using it period. Rather it be a day or a week. Thank you ladies.
