Meds to Avoid Before Surgery

What medications and foods should I avoid before surgery?

We have a list of over 200 medications, over the counter and prescription that are known to contain elements that would interfere with blood clotting, and we give it to the patient well in advance of the surgery and say look through this list, And we ask very specifically on our questionnaires what medicines are you taking, both prescription medications and non-prescription medications. We are trying to make sure the patient doesn't forget or doesn't disregard the importance of these medications that could interfere by the way not only with the bleeding, but even with the anesthesia. There are certain drugs that the anesthesiologist would be very unhappy if he didn't know the patient were taking.
