While the HealFast formula is designed to provide the least amount of interactions with common medications as well as anesthesia during the operative period; we love doctors, they are doctors, and would ALWAYS advise that you consult your personal doctor and/or anesthesiologist before surgery to ensure there are no complications with taking heal fast.
It's just a good habit to have. They welcome questions from patients and physicians at info@healfastproducts.com.
