There are numerous medications which will be prescribed for you at your pre-op/consent visit.  These include pain medication, nausea, and anti-spasm medications.  In some cases injectable blood thinners (such as Lovenox, enoxaprin, or heparin) to prevent blood clots.

Typically, the blood thinners are to be used AFTER surgery, unless you are undergoing bridging therapy.  Bridging therapy means that you are already on a blood thinner and are being switched over to Lovenox so that your regular blood thinner has time to wear off before surgery.  If this is the case and you are using injectable blood thinners prior to surgery, DO NOT DO AN INJECTION THE NIGHT BEFORE, OR THE MORNING OF YOUR PROCEDURE!
