September 25,2008 I was told to increase my dosage of Lisinopril from 10 mg to 20 mg and suddenly awoke on October 2, 2008 with a extremely swollen top lip, the degree was enough to get me into the ER room where I was issued Prednisone and Hydroxyzine with Famotidine which I had to take over the course of a few days to a week.
