Hello. I Was In The Hospital Last Night And Got

Posted on Wed, 9 Jan 2019

Question: Hello. I was in the hospital last night and got IV medication. I was wondering how long after you get the medicine would a severe allergic reaction begin? I got them around 2 AM. Should I be okay at this point? I received Iopamidol, NS bolus, zofran, reglan, pepcid and protonix. I've had a reaction to methylprednisolone a few weeks ago, so now I am a little worried anytime I take medicine. Thank you!
