A member asked:

Blood in urine bladder infection since two days on keflex and doxycycline now have chills and vomiting?

A doctor has provided 1 answer

Change antibiotic: Your vomiting could be due to medication side effects but if you are also having chills it may mean that you may be having pyelonephritis which means the infection has ascended up in the urinary tract into the lower part of the kidneys (especially if you also have fever and flank pain). You need to see your doctor to be rechecked and for a possible change in antibiotics.
