helicobacter pylori infection
"Given Prevpac for H. Pylori. Within 48 hrs of ending the full course of medication I experienced an anaphylactic reaction. Large, round, flat hives formed on the soft of my arms and inner thighs. My hands began to swell, and then I felt my face begin to swell. The swelling moved from left to right across my face, and it eventually began to close my throat and enlarge my tongue. My husband drove me to an urgent care center where I received a shot of Kenalog and a Medrol dose pack. I always list Prevpac as a medicine of which I am allergic."
