DR:
To the best of my knowledge, Retin-A itself has not caused problems, but is recommended to be avoided during pregnancy because of the risk of other members of the Vitamin A family for causing birth defects. This same concern would apply to Retinol, etc.
Most pregnant women want to take as few chances as possible, even if the risk is low. I'd stay away from this whole class of drugs. Your doctor can recommend others, such as those containing erythromycin, to tide you over.
Good luck!

Thank you for your response. Please clarify something for me. In your response to my question, you advised that I "stay away from this whole class of drugs". Were you including Alphy Hydroxy Acid (Glycolic Acid) in this class of drugs to be avoided prior and during pregnancy? Your advice is much appreciated. DR
