Although rare, allergic reactions to IV contrast can occur in a minority of patients. In this context, “at risk” reflects a higher risk for an acute allergic-like reaction, and it is most important to target premedication to i) those … BACKGROUND AND PURPOSE Management of contrast media allergies may lead to treatment delays in patients with acute ischemic stroke undergoing endovascular therapy. Contrast Allergy PreMed Pack TM PREDNISONE Do Shellfish Allergies Place Patients at Higher Risk for Contrast Reactions Than Other Allergies?

However, efficacy has been debated, especially in high-risk patients. 539 Davenport MS, Cohan RH, Caoili EM, Ellis JH. Although patients with non-elective PCI received more contrast fluid (120 ml vs 93 ml, P<0.0001) and their minimum premedication duration was longer (44 mins vs 26 mins, P<0.01) rate of breakthrough reaction was similar for both groups. 13-HOUR PREP Prednisone 50 mg (by mouth) q6 hours x 3 doses starting 13 hours prior to scan as: 13 hours + 7 hours + 1 hour prior to scan Dosing regimen: Dose 1 – Prednisone 50 mg 13 hours prior to scan Dose 2 – Prednisone 50 mg 7 hours prior to scan NDC 16129-101-01. double therapy.

Although modern low- and iso-osmolality iodine-based contrast media are generally well tolerated, there is an inherent risk of adverse reactions (1–3).In patients at risk of an allergic-like reaction to contrast media, the American College of Radiology recommends pretreatment with corticosteroids.The most common regimen is premedication over 13 hours (). Radiology 2009; 253:372. Steroid Premedication Regimens.
