Hi, I missed 2 doses of .5mg lorazepam 2 nights in a row. Plus I just took my 3rd dose of Cipro for UTI. About an hour after taking the antibiotic I felt very sick hard to put into words, sweating, dizzy, nauseated but did not vomit. Thinking it is the Cipro I called the urologist he stopped the Cipro will be on Keflex Yet the doctor on call doesn t really think it s an allergic reaction. Your thought.
