Brief Summary:
Both intravenous and oral acetaminophen have been shown to reduce post-operative pain scores when given preoperatively. This study investigates if there is a difference between the intravenous and the oral forms when given preoperatively to patients undergoing lumbar microdiscectomy. We hypothesize that the intravenous formulation does not improve pain scores or decrease opioid consumption during the first postoperative day compared to the oral formulation.

Arm Intervention/treatment
Active Comparator: oral acetaminophen
Patients in this arm of the study will receive oral acetaminophen and an IV placebo
Drug: oral acetaminophen
1000 milligrams given orally before surgery
Other Name: Tylenol

Active Comparator: intravenous acetaminophen
Patients in this arm of the study will receive IV acetaminophen and an oral placebo
Drug: intravenous acetaminophen
1000 milligrams of intravenous acetaminophen given before surgery
Other Name: Ofirmev

Primary Outcome Measures :
  1. Postoperative pain scores [ Time Frame: Day of surgery ]
    Pain scores are measured using a visual analog scale with patient at rest and also with movement of the lower extremities at four separate times following surgery.

Secondary Outcome Measures :
  1. Quantity of intraoperative and postoperative opioids administered. [ Time Frame: Day of surgery ]
    All doses of opioids given on the day of surgery will be recorded.
