Although there are no potential interactions between both meds, they are prescription medications only, and the one person who has to guide/clarify/advice you is the Dr. that prescribed them to you.
Your Dr. is responsible for your treatment and above all your safety, as he/she knows your medical background he/she must warn you of any potential risks involved with your treatment as well as the benefits of taking the medications prescribed to you by him/her.
