I am having radiofrequency ablation for control of my lower back pain. The prep instructions say that I should not take ACE Inhibitors or Monamine oxidase inhibitors (7-14 days) before surgery. Also Glucophage or blood thinners. These are the drugs I have questions about: amlodipine besylate, metropolol, sertraline, buspirone, lamotrigene, trazadone, hydroxyzine pam glimepiride hydrocodone-acetaminophen 5-325 I m sorry Dr Grief, I wish the website would have said this was a pay for information site. Iam unable to do so. Thank you.
