Hi, I scratched my hand on a rusted nail yesterday afternoon, even though it barely punctured my skin it is still a rusted nail, also given that I am on Isotretinoin ( Sotret) medication.10 mg daily for the past 2 months. I am wondering if the Tetanus shot would interact with Isotretinoin. I can t find any forums which state clearly whether it would or not. I am on my way to the hospital because I rather not risk getting infected but I would still like to be sure.
