This randomized, double-blind trial will compare the clinical efficacy of IV acetaminophen to that of IV ketorolac as adjuncts to standard therapy (prochlorperazine and diphenhydramine) in the treatment of patients presenting to the emergency department with chief complaint of "headache" or variants thereof.
After initial assessment of the patient by the provider, including careful review of inclusion and exclusion criteria, informed consent will be obtained. If a patient does not wish to participate in this study, he/she will receive alternative treatment at the discretion of their ED provider. The provider will place orders in the electronic medical record for "Headache study order set". This order set includes Compazine® 10 mg IV, Benadryl® 25 mg IV, and "study drug". Pharmacy will receive the order for the study drug. The research pharmacist will randomly assign participants to group A (1000 mg Ofirmev®) or group B (15 mg ketorolac). He/she will fill medication vials and IV bags in each "study kit". The kit for group A will contain a 100mL bag containing 1000 mg acetaminophen and a placebo vial of normal saline as well as both Compazine® and Benadryl®. The kit for group B will contain 100mL 0.9% normal saline and a vial containing 15 mg ketorolac as well as Compazine® and Benadryl®. The "study kit" will be sent to the emergency department via the tube system. When the study kit arrives, he/she will give each patient Compazine® and Benadryl®, hang the IV bag, and administer the contents of the vial. Therefore, every patient will receive a "push" of the contents in the vial (ketorolac or normal saline) and an 100mL infusion (Ofirmev or normal saline).

Pain Improvement
Comparison of the improvement in pain score between baseline and 60 minutes following analgesic administration, assessed using a Numeric Pain Rating Scale ( RATE PAIN FROM 0-10, with 0 = no pain and 10 = worst possible pain)
Time frame: 60 minutes
pain score at 30 minutes
ED staff will re-assess the patient and record level of pain at time of study drug administration and at 30 minutes after study drug administration, pain assessed using a Numeric Pain Rating Scale ( RATE PAIN FROM 0-10, with 0 = no pain and 10 = worst possible pain)
Time frame: 30 minutes
pain score at 90 minutes
ED staff will re-assess the patient and record level of pain at time of study drug administration and at 90 minutes after study drug administration, pain assessed using a Numeric Pain Rating Scale ( RATE PAIN FROM 0-10, with 0 = no pain and 10 = worst possible pain)
Time frame: 90 minutes
need for rescue medication in the ED
ED staff will re-assess the patient and record level of pain at time of study drug administration and at 90 minutes after study drug administration, pain assessed using a Numeric Pain Rating Scale ( RATE PAIN FROM 0-10, with 0 = no pain and 10 = worst possible pain)
Time frame: 90 minutes
patient's desire to receive the same medication again
prior to discharge the ED staff will ask the patient if they would like to receive the same medication again.
Time frame: 90 minutes
Need for rescue medication
If a rescue medication is required, the time, pain level, and type of medication given will be recorded. pain assessed using a Numeric Pain Rating Scale ( RATE PAIN FROM 0-10, with 0 = no pain and 10 = worst possible pain)
