Your doctor has requested that you obtain an intravenous contrast study to further evaluate your medical problem. The contrast contains an iodine compound to which you have previously exhibited an allergy. To provide the safest possible environment for your test, you are being pre-medicated to suppress your apparent allergy. It is still possible to have an allergic reaction even with this pre-medication; however, the risk is extremely low.

The prescription must be obtained from your referring physician. In addition to any other instructions you have received to prepare for this examination, you are to take the following medication at the prescribed times:

1. Take a 50 mg tablet of Prednisone and a 50 mg tablet of Benadryl at 5p.m. and 11 p.m. the night before your scheduled examination.

2. Take a 50 mg tablet of Prednisone and a 50 mg tablet of Benadryl along with your single dose (300 mg) of Tagamet two (2) hours prior to your scheduled appointment.

3. Remember not to take any solid foods after midnight prior to your scheduled appointment and take only enough liquids to take your oral doses of medication on the day of your study.
