Brief Answer: Not common and unlikely Detailed Answer: Hi and thank you so much for this query. Phytoceramides do no interact with any prescription medications. Ceramides are naturally occurring substances in the body. It is not like a foreign substance being introduced that may cause an interaction but merely increasing its levels for the benefits observed in persons with increased levels. This said, it is always a good idea to let your doctor know which other drugs or supplements you are taking. Consider talking to your treating doctor. I hope this addresses your query fully. Thank you so much for patronizing our services and please do feel free to ask for follow up clarifications and information if need be. I wish you the best of health. Dr. Ditah, MD.
