Mrsr........do you mean the ones like Octravin? Of so, both my OB's have told me that they it is totally OK if used sparingly. (I would just use a single squirt at night so I could breath OK to sleep........).

The box does say "Only on the advice of a Dr". I trusted both my OB's and went ahead. and with absolutely no ill effects on my babies.......but I would check with your Dr.
