Omnicef and steroids

(33yr) Was given Omnicef for an ear infection. After 3rd dose broke out with huge patches of red whelps. Stop taking, but then my joints started to ache and I had large knots on the bottom of my feet and hands. Diarrhea and vomiting, severe stomache cramps and low blood pressure... followed by antiphylatic shock. While I was in the ER the discovered I was also having a heart attack.

It has been 3 weeks and every time I come off the steroids, the rash and other symtoms return.

Has anyone else had similar problems.

My 16 yr old son was prescribed this drug 9 days ago for a severe sinus infection. He came home from school yesterday with several small raised welts on the creases of his arms. I took him immediately back to his Dr who said he was having an allergic reaction, prescribed steroids and said it would get worse before it got better. Within a few hours his elbows had visible knots in different places, then his knees did the same thing, then his feet started getting knots on the bottom and he had different whelps breaking out on his torso and lower stomach. We immediately took him to the ER last night when he said his tongue "felt funny". The attending immediately diagnosed an acute severe allergic reaction and gave him a huge steroid and Benadryl dose. He released him because the itching had stopped and his tongue no longer felt funny. Last night he kept drenching himself with sweat during sleep. Today so far some of the whelps are gone but he has some pretty severe joint involvement with visible knots around the elbow and knees and feet.
