Is it safe to use pulmicort and ventolin during pregnancy?

Yes: If these are for asthma, the answer to your question is yes. Pulmicort is pregnancy category b which is good. Albuterol should only be used if needed and if you need it you should use it. However if you find that you are having to use your albuterol more than usual or find that it is not providing relief, you should be evaluated by your physician.
