question: I gave my 4 years old son (40 lb) an Ultrafen (iBuprofen) 200mg suppository (to treat 38.8C fever). After one hour he got a rash all over his body and I discovered than the medicine was expired (12/2010). His temperature is down now and the rash is gone.Is there anything I should do now? I gave him one (from the expired suppository) yesterday too.
